Where’s my Endpoint?

Cisco Study Materials, Cisco Guides, Cisco Certifications, Cisco Guides, Cisco Online Exam, Cisco Exam Prep

Is there a way to know what endpoints are alive within your data center at this moment? Is it possible to continuously monitor the life of every endpoint – be it a Virtual Machine (VM), a physical host or even a container ? Enter Endpoint Locator or EPL!

With DCNM available as a manager for data center fabrics, we decided to incorporate EPL directly into DCNM. EPL has been shipping as a preview feature in DCNM since November 2016. General availability of this feature is now available with the DCNM 10.2(1) May 2017 release.

For a VXLAN BGP EVPN based data center fabric, Endpoint Locator provides near real-time tracking of every endpoint. Events such as endpoint coming up, endpoint going down, or endpoint move are now visible with a few simple clicks. EPL supports all kinds of endpoints, be it IPv4, IPv6 or Dual-Stack. In fact, EPL can literally locate anything with a MAC or IP address.

To provide context to the detected endpoint itself, additional information is gathered and correlated, resulting in a multitude of data points at your fingertips. Find your endpoints physical location with the reference to the associated switch and connected physical interface. Add in logical information such as VLAN, VRF or VNIs. The ease of access and visibility of such information within the data center is unprecedented for data center fabrics.

Once EPL is enabled via a simple wizard, it starts gathering information about existing endpoints and from then onward, all network events associated with the endpoint will be tracked.

Apart from a live endpoint dashboard, EPL also displays endpoint historical information for a time period specified in absolute or relative data ranges. The endpoints can be filtered by a variety of parameters including the VRF, network identifier, switch name, etc. Any search results are available for instant download.

In addition to the dashboard, EPL offers a set of Operational and Exploratory analytics views that are based on the collected endpoint data.

◉ Network Historical View – Displays daily historical information about endpoints, networks, and VRFs in terms of currently active endpoints, endpoint additions & deletions.

◉ Operational Heatmap – Displays holistic information on all the operations that have been occurring in the fabric on an hourly basis.

◉ Endpoint Life – Displays a timeline of a particular endpoint throughout its entire existence within the fabric showing where the endpoint was located and where it has moved.


Stay tuned for more innovations like these which drive operational simplicity and visibility into data center fabrics using DCNM.

A Special acknowledgement to Shyam Kapadia for being the primary development lead for EPL; our journey started with an innocent break room conversation about a customer problem with respect to workload visibility.

Do the Impossible: Deliver the Best Collaboration Experience and Secure Sensitive Data with Cisco’s Extended Secur …

Security is Paramount, and Cisco Webex is the Market Leader


Security is critical for any collaboration deployment because employees inevitably share sensitive data and intellectual property. Building out security is hard as it’s not a standalone feature that can be built in isolation. It is a platform-level capability that needs to be designed for every component and every feature support must comply with it to be effective.

Cisco Study Materials, Cisco Guides, Cisco Learning, Cisco Tutorial and Materials, Cisco Prep

Cisco has security in its DNA from the network to devices to the cloud. Cisco Webex was architected with a 360 approach to security. We looked at the full attack surface and possible threat vectors to build controls and mitigations while providing the best user experience, and enabling users to securely collaborate with users outside of their companies and support their personal devices.

Customer Challenges


Users are increasingly using collaboration tools to do their job – and it often involves sensitive data – whether it’s intellectual property, personally identifying information or financial information. Line of business executives and IT administrators are concerned about data loss especially when their users are collaborating externally. As an open platform, Webex has an events API and one of the largest compliance and Data Loss Prevention (DLP) partner ecosystems in the industry to address these concerns.

However, many of our customers do not have a central DLP solution deployed and this stalls rollout of modern collaboration tools. Even if some customers deploy these tools, IT admins end up blocking collaboration with external users and use of personal devices in order to mitigate these data loss risks.

Not only does this impact employee adoption of these tools, it increases data loss and malware exposure as users start using non-sanctioned consumer collaboration apps to get the job done.

Extended Security Pack Solution


I am thrilled to announce a new Collaboration Flex add-on offer – the Cisco Webex Control Hub Extended Security Pack – a Cisco-on-Cisco best of breed solution to this customer problem that packages full functionality Cisco Cloudlock for Webex Teams with native Webex anti-malware capabilities powered by Cisco Talos ClamAV in Webex Cloud.

The new Extended Security Pack is available now and enables our customers to safely and securely rollout modern collaboration with best user experience.

Cisco Study Materials, Cisco Guides, Cisco Learning, Cisco Tutorial and Materials, Cisco Prep

Cloudlock DLP policies follow your employees even when they collaborate with external users. And our anti-malware solution will block infected files from being downloaded and malicious URLs will not be expanded and clearly marked for end-users.

Peace of Mind Through Industry Leading Webex Teams Security


We firmly believe that every customer is different and there is “no one size fits all” security model, and therefore IT Admins can choose Webex Control Hub policies to match Webex security to their risk profile. We are announcing new controls to manage 3rd party integrations like JIRA, Box, and Smartsheet into Webex. The ability to manage bots and whitelist external domains for collaboration will be available in October. In addition, Control Hub now supports active directory groups for automatic license assignment based on your geography, role or other criteria.

We are very excited to partner with ThetaLake to support AI-based archiving, eDiscovery, and supervision for Webex Meetings recordings with automated detection of compliance risks in audio and visual content, including screenshares.

The new Control Hub search and extraction tool is available now and will support large lawsuits and investigations by allowing hundreds of users in one query. In addition, a simple EML export mechanism will allow faster integration into eDiscovery tools and quick viewing of extracted content for internal investigations.

Trust and Protection You Can Count on 


Webex has tight controls on privacy and personal identifiable information and supports various cross-border frameworks and is GDPR compliant. ISO 27018 is the first certification to focus on privacy and PII controls and Webex Meetings and Teams have passed the ISO27018 audit.

Webex is adding new built-in mobile application management (MAM) capabilities to set up a timeout for Teams mobile client with application PIN lock and an ability to block notifications with message content on lock screen. In addition, we are proud to announce a common mechanism for customers to wrap all Webex mobiles apps (Meetings, Teams and Jabber) using their favorite MAM SDK starting October 2019.

The 3 W’s in Zero Trust Security

Picture this scenario: you are a security guard at an office building. Today you are looking after a restricted area. A person you’ve never seen before walks straight past you into one of the rooms. Would you stop them or would you just assume they are allowed to be there?

In a physical world, trust is most commonly based on who you are, not where you are. A savvy security guard would ask you for your ID before allowing you in. Virtually, though, the situation is different: being in the right place is often enough. If you are inside of a company’s network perimeter, it is often assumed you have the right to be there. You gain access to the same data and tools that any other trusted user would. It’s clear that such an approach is no longer enough.

Zero trust security comes in as an alternative model, more in line with the current threat landscape.  It is based on the principle of “always check, never trust“, originally introduced by Forrester. It takes into account 3 main factors:

◉ Workforce: Employees are at risk of identity theft, which is one of the most widespread types of fraud today.

◉ Workload: New vulnerabilities in applications and their improper management open highways for cybercriminals.

◉ Workplace: With more and more connected devices, the workspace has extended far beyond the four walls of you company building.

Moving from a perimeter model to Zero Trust means assessing, adapting and implementing new security policies that address threats in a constantly changing environment. In this trust-centric approach access is granted to users and devices, not a network.

Cisco Tutorial and Materials, Cisco Learning, Cisco Online Exam, Cisco Security

This means that policies now need to be calculated based on a vast number of data sources. All network activities must be continuously taken into account. Any indications of compromise or changes in the behaviour of apps, users and devices must be examined, validated and receive immediate responses.

How to apply a Zero Trust model


Cisco’s practical approach to Zero Trust includes six important steps.

1. Establish levels of trust for users and user devices (identity verification with multi-factor authentication and device status, which must be compliant and properly updated)
2. Establish levels of reliability for IoT and/or workloads (profile and baseline)
3. Establish SD perimeters to control access to the application (authorised access)
4. Establish SD perimeters to control access to the network (segmentation and micro-segmentation)
5. Automate the adaptive policy using normalisation (network, data centre and cloud)
6. Automate the adaptive policy using the response to threats (adapt the level of trust)

Zero Trust Security involves people, processes and technology in its adoption. It can provide a roadmap for a truly efficient and automated security infrastructure.

Ransomware in Education: How to use your Network to Stay Ahead of Attacks

Cisco Study Materials, Cisco Guides, Cisco Certifications, Cisco Exam Prep

Educational institution systems store a large amount of sensitive data, including student and employee records. They rely heavily on these systems for day-to-day operations. So any disruption or loss of access can be a game changer. But these same institutions also often have tight budgets and can’t afford to employ large security teams. That’s one reason they’re perceived as easy and lucrative targets by online adversaries.

A typical response may be to deploy multiple security technologies to block threats from entering your organization at various attack vectors, and you should continue to do so. However, just relying on these techniques isn’t enough since 100% prevention is not possible in today’s complex threat landscape. That’s where continuous monitoring of your network’s behavior comes in. By using this approach, you can help detect and respond to a ransomware attack more quickly and effectively.

How to stay ahead of cyber threats


Your network is a source-of-truth of every activity – normal or malicious. Adversaries must use your network in order to carry out their malicious objectives. Because of this, collecting and analyzing your network telemetry is an effective way of detecting advanced threats, like ransomware. Here’s how it helps you.

◉ Detect threats early by pinpointing suspicious behavior. Ransomware attacks are generally initiated through methods like a phishing email or exploitation of a vulnerability. It might involve behavior such as port scanning, command-and-control (C&C) communication back to the attacker network, etc. Whatever means the attackers use, the activity touches the network. By using behavioral modeling, this kind of activity can be easily detected. You can also create custom security policy alerts to detect restricted communications such as use of SMB protocol, or access to sensitive data servers from outside the network. So even if the ransomware is an unknown strain and has infected the organization, the anomalous behavior will give the attackers away.

◉ Correlate local alerts to global campaigns. Attackers often reuse ransomware strains to infiltrate multiple organizations. An effective network security analytics solution is powered by industry-leading threat intelligence that has the knowledge of all the malicious domains, servers, campaigns, and other indicators of compromise. Using multiple analytical techniques like statistical modeling and machine learning, billions of network sessions within your organization can be processed and correlated to global campaigns, in order to pinpoint attacks and then quickly remediate.

◉ Perform forensic analysis for incident response. Your organization has been infected, and you have been immediately notified through alerts of the ransomware attack. Now what? Time is of the essence and your security teams need to answer questions like what machines have been infected, what was the source of the attack, and where are communications occurring? Because you have a record of every network communication, you can begin from the alert and investigate back in time to conduct a thorough forensic analysis to answer those questions and contain the ransomware.

Industry-leading network visibility and security analytics


The capabilities described above are offered by Cisco’s network traffic analysis solution, called Cisco Stealthwatch. It provides enterprise-wide visibility, from the private network to the public cloud, and applies advanced security analytics to detect and respond to threats in real-time.

By using a combination of behavioral modeling, machine learning, and global threat intelligence, Stealthwatch can quickly (and with high confidence) detect threats such as:

◉ C&C attacks
◉ Ransomware
◉ DDoS attacks
◉ Illicit cryptomining
◉ Unknown malware
◉ Insider threats.

With a single, agentless solution, you get comprehensive threat monitoring across your data center, branch, endpoint, and cloud. Plus, it can also analyze encrypted traffic for threats, without any decryption, using our proprietary Encrypted Traffic Analytics technology.

Cisco Study Materials, Cisco Guides, Cisco Certifications, Cisco Exam Prep
Stealthwatch can detect ransomware hiding in encrypted traffic, and can also correlate it to global campaigns like WannaCry.

By deploying Stealthwatch, you can turn your network into a “threat sensor” by simply collecting telemetry such as NetFlow. And there is no need to deploy multiple agents. Stealthwatch can be deployed easily. Best of all, it scales automatically with your infrastructure, growing as your needs grow.

Using Automation with your Security Products

Cisco Study Materials, Cisco Tutorials and Material, Cisco Guides, Cisco Online Exam
For network engineers, automation is changing the way we interact with the network devices that are a key part of our responsibilities. This is a fundamental change in the way that we’re used to controlling these devices. And if you’re a network engineer, it’s natural that you might be hesitant to use automation because you think it might reduce the number of engineers required to maintain devices. But I challenge you to think first about the increased efficiency that it will provide.

Three reasons to embrace network automation


It’s important to remember that network automation is not just another “flavor of the month” but the future of our industry. So now is a prime opportunity for you to lead rather than follow. I suggest you embrace it and by doing so become a better engineer. And as you begin, understand that there are three key reasons you should implement network automation:

◉ To reduce configuration errors. Automating the repetitive configurations used in the network will help reduce your error rates caused by manually configuring the devices.

◉ Improve network management. Many processes you perform regularly on your devices may not get done, or experience a delay, due to the manual nature of the tasks. Automating them is a great way to ensure they get done.

◉ Free up your IT Staff for critical tasks. By using automation for less critical tasks, it allows your team to focus on performing the critical tasks that ensure the network is running at peak efficiency.

Four tools for network automation


Now, let’s look at four tools you can use for automating your network:

◉ Python is quickly becoming one of the most used languages for automation. It’s a much more human readable language.

◉ Github is a great repository for code used for automation. Plus, there are numerous Cisco supported repositories on Github. So you can download these to jump start your automation journey.

◉ Postman is a great tool to get you going with interacting with your network devices.

◉ Ansible is a great network automation platform.

Cisco DevNet and network automation


Next we need to look to Cisco DevNet. Cisco has announced new certifications around network automation, and they’ve put countless hours into developing a world class training and development environment:

Enterprise Networking in 2020: 5 Trends to Watch in Wireless, SD-WAN, More

Networking isn’t what it used to be. A few years ago, the epicenter of networking began to move. It shifted from company-owned datacenters, out to the cloud. For users, the focus of networking moved from computers connected with wires, to mobile devices connected over the air. These fundamental shifts, in where business processes run and how they’re accessed, is changing how we connect our locations together, how we think about security, the economics of networking, and what we ask of the people who take care of them.

So it is going to be an exciting year. Here’s how:

Wireless: It’s Wi-Fi, It’s 5G. It’s Both.


In 2020, Wi-Fi 6 will enter the enterprise, through the employee door and through enterprise access point refreshes. 5G will also appear, although in 2020, it will be mostly for consumers.

The latest smartphones from Apple, Samsung, and other manufacturers are Wi-Fi 6 enabled, and Wi-Fi 6 access points are currently shipping to businesses and consumers. 5G phones are not yet in wide circulation, although that will begin to change in 2020. We project that through 2020 more people will be using Wi-Fi 6 than 5G.

2020 will also see the beginning of a big improvement in how people use Wi-Fi networks. The growth of the OpenRoaming project will make joining participating Wi-Fi networks as easy as using a cell phone in a new town: Users won’t have to think about it.

While “5G” service will roll out in 2020 (some is already switched on today), almost none of it will be the ultra-high speed connectivity that we have been promised or that we will see in future years. With 5G unable to deliver on that promise initially, we will see a lot of high-speed wireless traffic offloaded to Wi-Fi networks.

2020 will also see the adoption of new frequency bands, including the beginning of the rollout of “millimeter wave” (24Ghz to 100Ghz) spectrum for ultra-fast, but short-range 5G; and of CBRS, at about 3.5Ghz, which may lead to the creation of new private networks that use LTE and 5G technology, especially for IoT applications. We will also see continued progress in opening up the 6 GHz range for unlicensed Wi-Fi usage in the United States and the rest of world.

Eventually, having even more pervasive, high-speed, secure wireless connectivity will open up new kinds of business opportunities in all industries, from healthcare to transportation. In combination with the improved performance of both Wi-Fi 6 and (eventually) 5G, we are in for a large – and long-lived – period of innovation in access networking.

The Network as Intelligent Sensor


Businesses have started to use their networks for more than data transmission. Now they’re being used to sense their environments as well. This is going to have big impacts on business – not just for network operators, but directly to the bottom line as well.

With software that is able to profile and classify the devices, end points, and applications (even when they are sending fully encrypted data), the network will be able to place the devices into virtual networks automatically, enable the correct rule set to protect those devices, and eventually identify security issues extremely quickly. Ultimately, systems will be able to remediate issues on their own, or at least file their own help desk tickets. This becomes increasingly important as networks grow increasingly complex.

Wireless networking equipment can also collect data on how people and things move through and use physical spaces – for example, IoT devices in a business; or medical devices in a hospital. That data can directly help facility owners optimize their physical spaces, for productivity, ease of navigation, or even to improve retail sales. These are capabilities that have been rolling out in 2019, but as business execs become aware of the power of this location data, the use of this technology will begin to snowball.

SD-WAN Plans Solidify in 2020


The workplace is becoming virtual, not physical. Businesses now hire talent wherever it is, and these dispersed employees are connecting to increasing numbers of cloud services. This dispersal of connectivity – the growth of multicloud networking – will force many businesses to re-tool their networks in favor of SD-WAN technology. IDC research shows that almost 95% of the enterprises they surveyed expect to be using SD-WAN within 24 months.

Meanwhile the large cloud service providers, like Amazon, Microsoft, and Google are connecting to networking companies (like Cisco), to forge deep partnership links between networking stacks and services.

When it comes to their own WAN solutions, each enterprise is different. Some enterprises, looking for security solutions that align with compliance regulations, need on-premise security. Smaller businesses often want their security solutions in the cloud. Many businesses will need hybrid solutions that combine elements of traditional on-premise control for compliance, with cloud-based solutions for flexibility and agility. Security, and workloads, have to be installed where they meet the needs of the business.

This is going to lead to a growth in business for managed service providers (MSPs), many more of which will begin to offer SD-WAN as a service. We expect MSPs to grow at about double the rate of the SD-WAN market itself, in line with IDC’s predictions. We also expect that MSPs will begin to hyper-specialize, by industry and network size.

Multidomain Needs Spur Controller-Based Integration


The intent based networking model that enterprises began adopting in 2019 is making network management more straightforward by absorbing the complexities of the network. However, networking systems are made up of multiple networks themselves (for example, campus networks and WANs), as well as domains of technology that are traditionally managed in their own domains (for example, security). For better management, agility, and especially for security, these multiple domains need to work together. Each domain’s controller needs to work in a coordinated manner to enable automation, analytics and security across the various domains.


Increasing network complexity fuels adoption of multidomain technologies.

The next generation of controller-first architectures for network fabrics allow the unified management of loosely-coupled systems using APIs and defined data structures for inter-device and inter-domain communication. With the way networks are changing, there is no other solution to keep ahead of system growth and complexity.

From Network Engineer to Network Programmer


The standard way that network operators work – provisioning network equipment using command-line interfaces like CLI – is nearing the end of the line. Today, intent-based networking lets us tell the network what we want it to do, and leave the individual device configuration to the larger system itself. We can also now program our updates, rollouts, and changes using centralized networking controllers, again not working directly with devices or their own unique interfaces. But new networks run by APIs require programming skills to manage. Code is the resource behind the creation of new business solutions.

If maximizing the value of these controllers means getting up to speed with programming them, there’s a big opportunity for the people who get ahead of this trend. But it will not be an easy change. Retraining yourself (or your team) is expensive, and not everyone will adapt to the new order. For those that do, the benefits are big. Network operators will be closer to the businesses they work for, able to better help businesses achieve their digital transformations. The speed and agility they gain thanks to having a programmable network, plus telemetry and analytics, opens up vast new opportunities.

It remains critical for individuals to validate their proficiency with new infrastructure and network engineering concepts. With training, network operators will be able to stay closer to the businesses they work for, providing value beyond maintenance and support. Networks in 2020 will become even more central to how businesses function. As always, CEOs will direct resources into infrastructure projects that directly generate revenue.       

2020 Will be Transformative


Together, new capabilities will make networks into even more important business assets, and companies will leverage them in ways that we have not imagined.

We just finished surveying over 2,000 network executives and operators on the future of networking.

Why Upgrade to MDS 9700

MDS 9500 family has supported customers for more than a decade helping them  through FC speed transitions from 1G, 2G, 4G, 8G and 8G advanced without forklift upgrades. But as we look in the future the MDS 9700 makes more sense for a lot of data center designs.  Top four reasons for customers to upgrade are

1. End of Support Milestones
2. Storage Consolidation
3. Improved Capabilities
4. Foundation for Future Growth

So lets look at each in some detail.

1. End of Support Milestones


MDS 4G parts are going End of Support on Feb 28th 2015. Impacted part numbers are DS-X9112, DS-X9124, DS-X9148. You can use the MDS 9500 Advance 8G Cards or MDS 9700 based design. Few advantages MDS 9700 offers over any other existing options are

a. Investment Protection – For any new Data Center design based on MDS 9700 will have much longer life than MDS 9500 product family. This will avoid EOL concerns or upgrades in near future. Thus any MDS 9700 based design will provide strong investment protection and will also ensure that the architecture is relevant for evolving data center needs for more than a decade.

b. EOL Planning – With MDS 9700 based design you control when you need to add any additional blades but with MDS 9500, you will have to either fill up the chassis within 6 months (End of life announcement to End of Sales) or leave the slots empty forever after End of Sale date.

c. Simplify Design – MDS 9700 will allow single skew, S/W version, consistent design across the whole fabric which will simplify the management. MDS 9700 massive performance allows for consolidation and thus reducing footprint and management burden.

d. Rich Feature Set – Finally as we will see later MDS provides host of features and capabilities above and beyond MDS 9500 and that enhancement list will continue to grow.

Cisco Certifications, Cisco Tutorial and Material, Cisco Guides, Cisco Learning, Cisco Online Exam

2. Storage Consolidation


MDS 9700 provides unprecedented consolidation compared to the existing solutions in the industry. As an example with MDS 9710 customers can use the 16G Line Rate ports to support massively virtualized workload and consolidate the server install base. Secondly with 9148S as Top of Rack switch and MDS 9700 at Core, you can design massively scalable networks supporting consistent latency and 16G throughput independent of the number of links and traffic profile and will allow customers to Scale Up or Scale Out much more easily than legacy based designs or any other architecture in the industry.

Moreover as shown in figure above for customers with MDS 9500 based designs MDS 9710 offers higher number of line rate ports in smaller footprint and much more economical way to design SANs. It also enables consolidation with higher performance as well as much higher availability.

Cisco Certifications, Cisco Tutorial and Material, Cisco Guides, Cisco Learning, Cisco Online Exam

3. Improved Capabilities


MDS 9700 design provides more enhanced capabilities above and beyond MDS 9500 and many more capabilities will be added in future. Some examples that are top of mind are detailed below

Availability: MDS 9700 based design improves the reliability due to enhancements on many fronts as well as simplifying the overall architecture and management.

◉ MDS 9710 introduced host of features to improve reliability like industry’s first N+1 Fabric redundancy, smaller failure domains and hardware based slow drain detection and recovery.

◉ Its well understood that reliability of any network comes from proper design, regular maintenance and support. It is imperative that Data Center is on the recommended releases and supported hardware. As an example data center outage where there are unsupported hardware or software version failure are exponentially more catastrophic as the time to fix those issues means new procurement and live insertion with no change management window. Cost of an outage in an Data Center is extremely high so it is important to keep the fabric upgraded and on the latest release with all supported components. Thus for new designs it makes sense that it is based on the latest MDS 9700 directors, as an example, rather than MDS 9513 Gen-2 line cards because they will fall of the support on Feb 28, 2015. Also a lot of times having different versions of the hardware and different software versions add complexity to the maintenance and upkeep and thus has a direct impact on the availability of the network as well as operational complexity.

Throughput:

With massive amounts of virtualization the user impact is much higher for any downtime or even performance degradation. Similarly with the data center consolidation and higher speeds available in the edge to core connectivity more and more host edge ports are connected through the same core switches and thus higher number of apps are dependent on consistent end to end performance to provide reliable user experience. MDS 9700 provides industries highest performance with 24Tbps switching capability. The Director class switch is based on Crossbar architecture with Central Arbitration and Virtual Output Queuing which ensures consistent line rate 16G throughput independent of the traffic profile with all 384 ports operating at 16G speeds and without using crutches like local switching (muck akin to emulating independent fixed fabric switches within a director), oversubscription (can cause intermittent performance issues) or bandwidth allocation.

Latency:

MDS Directors are store and forward switches this is needed as it makes sure that corrupted frames are not traversing everywhere in the network and end devices don’t waste precious CPU cycles dealing with corrupted traffic. This additional latency hit is OK as it protects end devices and preserves integrity of the whole fabric. Since all the ports are line rate and customers don’t have to use local switching. This again adds a small latency but results in flexible scalable design which is resilient and doesn’t breakdown in future. These 2 basic design requirements result in a latency number that is slightly higher but results in scalable design and guarantees predictable performance in any traffic profile and provides much higher fabric resiliency .

Consistent Latency: For MDS directors latency is same for the 16G flow to when there are 384 16G flows going through the system. Crossbar based switch design, Central arbitration and Virtual Output Queuing guarantees that. Having a variable latency which goes from few us to a high number is extremely dangerous. So first thing you need to make sure is that director could provide consistent and predictable latency.

End to End latency: Performance of any application or solution is dependent on end to end latency. Just focusing on SAN fabric alone is myopic as major portion of the latency is contributed by end devices. As an example spinning targets latency is of the order of ms. In this design few us is orders of magnitude less and hence not even observable. With SSD the latency is of the order of 100 to 200 us. Assuming 150 us the contribution of SAN fabric for edge core is still less than 10%. Majority (90%) of the latency is end devices and saving couple of us in SAN Fabric will hardly impact the overall application performance but the architectural advantage of CRC based error drops and scalable fabric design will make provided reliable operations and scalable design.

Scalability:

For larger Enterprises scalability has been a challenge due to massive amount of host virtualization. As more and more VMs are logging into the fabric the requirement from the fabric to support higher flogins, Zones. Domains is increasing. MDS 9700 has industries highest scalability numbers as its powered by supervisor that has 4 times the memory and compute capability of the predecessor. This translates to support for higher scalability and at the same time provides room for future growth.

Cisco Certifications, Cisco Tutorial and Material, Cisco Guides, Cisco Learning, Cisco Online Exam

4. Foundation for Future Growth:


MDS 9700 provides a strong foundation to meet the performance and scalability needs for the Data Center requirements but the massive switching capability and compute and memory will cover your needs for more than a decade.

◉ It will allow you to go to 32G FC speeds without forklift upgrade or changing Fabric Cards (rather you will need 3 more of the same Fabric card to get line rate throughput through all the 384 ports on MDS 9710 (and 192 on MDS 9706).

◉ MDS 9700 allow customers to deploy 10G FCoE solution today and upgrade without forklift upgrade again to 40G FCoE.

◉ MDS 9700 is again unique such that customers can mix and match FC and FCoE line cards any way they want without any limitations or constraints.

Most importantly customers don’t have to make FC vs FCoE decision. Whether you want to continue with FC and have plans for 32G FC or beyond or if you are looking to converge two networks into single network tomorrow or few years down the road MDS 9700 will provide consistent capabilities in both architectures.

Cisco Certifications, Cisco Tutorial and Material, Cisco Guides, Cisco Learning, Cisco Online Exam

In summary SAN Directors are critical element of any Data Center. Going back in time the basic reason for having a separate SAN was to provide unprecedented performance, reliability and high availability. Data Center design architecture has to keep up with the requirements of new generation of application, virtualization of even the highest performance apps like databases, new design requirements introduced by solutions like VDI, ever increasing Solid State drive usage, and device proliferation. At the same time when networks are getting increasingly complex the basic necessity is to simplify the configuration, provisioning, resource management and upkeep. These are exact design paradigms that MDS 9700 is designed to solve more elegantly than any existing solution.
