Most days of the week, you can expect to see AI- and/or sustainability-related headlines in every major technology outlet. But finding a solution that is future ready with capacity, scale and flexibility needed for generative AI requirements and with sustainability in mind, well that’s scarce.

Cisco is evaluating the intersection of just that – sustainability and technology – to create a more sustainable AI infrastructure that addresses the implications of what generative AI will do to the amount of compute needed in our future world. Expanding on the challenges and opportunities in today’s AI/ML data center infrastructure, advancements in this area can be at odds with goals related to energy consumption and greenhouse gas (GHG) emissions.

Addressing this challenge entails an examination of multiple factors, including performance, power, cooling, space, and the impact on network infrastructure. There’s a lot to consider. The following list lays out some important issues and opportunities related to AI data center environments designed with sustainability in mind:

1. Performance Challenges: The use of Graphics Processing Units (GPUs) is essential for AI/ML training and inference, but it can pose challenges for data center IT infrastructure from power and cooling perspectives. As AI workloads require increasingly powerful GPUs, data centers often struggle to keep up with the demand for high-performance computing resources. Data center managers and developers, therefore, benefit from strategic deployment of GPUs to optimize their use and energy efficiency.

2. Power Constraints: AI/ML infrastructure is constrained primarily by compute and memory limits. The network plays a crucial role in connecting multiple processing elements, often sharding compute functions across various nodes. This places significant demands on power capacity and efficiency. Meeting stringent latency and throughput requirements while minimizing energy consumption is a complex task requiring innovative solutions.

3. Cooling Dilemma: Cooling is another critical aspect of managing energy consumption in AI/ML implementations. Traditional air-cooling methods can be inadequate in AI/ML data center deployments, and they can also be environmentally burdensome. Liquid cooling solutions offer a more efficient alternative, but they require careful integration into data center infrastructure. Liquid cooling reduces energy consumption as compared to the amount of energy required using forced air cooling of data centers.

4. Space Efficiency: As the demand for AI/ML compute resources continues to grow, there is a need for data center infrastructure that is both high-density and compact in its form factor. Designing with these considerations in mind can improve efficient space utilization and high throughput. Deploying infrastructure that maximizes cross-sectional link utilization across both compute and networking components is a particularly important consideration.

5. Investment Trends: Looking at broader industry trends, research from IDC predicts substantial growth in spending on AI software, hardware, and services. The projection indicates that this spending will reach $300 billion in 2026, a considerable increase from a projected $154 billion for the current year. This surge in AI investments has direct implications for data center operations, particularly in terms of accommodating the increased computational demands and aligning with ESG goals.

6. Network Implications: Ethernet is currently the dominant underpinning for AI for the majority of use cases that require cost economics, scale and ease of support. According to the Dell’Oro Group, by 2027, as much as 20% of all data center switch ports will be allocated to AI servers. This highlights the growing significance of AI workloads in data center networking. Furthermore, the challenge of integrating small form factor GPUs into data center infrastructure is a noteworthy concern from both a power and cooling perspective. It may require substantial modifications, such as the adoption of liquid cooling solutions and adjustments to power capacity.

7. Adopter Strategies: Early adopters of next-gen AI technologies have recognized that accommodating high-density AI workloads often necessitates the use of multisite or micro data centers. These smaller-scale data centers are designed to handle the intensive computational demands of AI applications. However, this approach places additional pressure on the network infrastructure, which must be high-performing and resilient to support the distributed nature of these data center deployments.

As a leader in designing and supplying the infrastructure for internet connectivity that carries the world’s internet traffic, Cisco is focused on accelerating the growth of AI and ML in data centers with efficient energy consumption, cooling, performance, and space efficiency in mind.

These challenges are intertwined with the growing investments in AI technologies and the implications for data center operations. Addressing sustainability goals while delivering the necessary computational capabilities for AI workloads requires innovative solutions, such as liquid cooling, and a strategic approach to network infrastructure.

The new Cisco AI Readiness Index shows that 97% of companies say the urgency to deploy AI-powered technologies has increased. To address the near-term demands, innovative solutions must address key themes — density, power, cooling, networking, compute, and acceleration/offload challenges.

We want to start a conversation with you about the development of resilient and more sustainable AI-centric data center environments – wherever you are on your sustainability journey. What are your biggest concerns and challenges for readiness to improve sustainability for AI data center solutions?

Disaster Recovery Solutions for the Edge with HyperFlex and Cohesity

The edge computing architecture comes with a variety of benefits. Placement of compute, storage, and network resources close to the location at which data is being generated typically improves response times and may reduce WAN based network traffic between an Edge site and central data center. This stated the distributed nature of edge site architectures also introduces several challenges related to data protection and disaster recovery. One requirement is performing local backups with the ability to conduct local recovery operations. Another formidable challenge involves edge site disaster recovery. Planning for the inevitable edge site outage, be it temporary, elongated, or permanent is the problem this blog takes a deeper look into.

Business continuity planning focuses on items such as Recovery Point Objective (RPO) and Recovery Time Objective (RTO). These measurements are generally expressed in terms of a Service Level Agreement (SLA). Under the covers exists a collection of infrastructure building blocks that make adherence to an SLA possible. In simplistic terms, the building blocks include the ability to perform backups, the ability to create additional copies of backups, provide a methodology to transport backup copies to remote locations (replication), an intuitive management interface, and connects to a preconfigured recovery infrastructure.

From an operational standpoint, an edge site disaster recovery solution includes workflows that enable the ability to:

◉ Perform workload failover from an edge site to a central site.

◉ Protect failed over workload at a central site.

◉ Reverse replicate protected workloads from a central site back to an edge site at the point where the edge site is ready to receive inbound replication traffic.

◉ Failover again such that the edge site once again hosts production workloads.

◉ Test these operations without impacting production workloads.

Should an edge site failure or outage occur, workload failover to a disaster recovery site may become necessary. (Quite obviously, disaster recovery operations should be tested on an ongoing basis rather than just hoping things will work.) At the point where workload failover has been completed successfully, the failed over workload requires data protection. At the point where the edge site has been returned to an operational state, backup copies should be replicated back to the edge site. Alternatively, a new or different edge site may replace the original edge site. At some point, workload transition from the central site back to the edge site will occur.

HyperFlex with Cohesity Data Protect

Cohesity provides a number of DataProtect solutions to assist users in meeting data protection and disaster recovery business requirements. The Cohesity DataProtect product is available as a Virtual Edition and can be deployed as a single virtual machine hosted on a HyperFlex Edge cluster. A predefined small or large configuration is available for selection when the product is installed. The Cohesity DataProtect solution is also available in a ROBO Edition, running on a single Cisco UCS server.

Cohesity DataProtect edge solutions provide local protection of virtual machine workloads and can also replicate local backups to a larger centralized Cohesity cluster deployed on Cisco UCS servers.

Cohesity protection groups are configured and define the workloads to protect. Protection groups also include a policy that defines the frequency and retention period for local backups. The policy also defines a replication destination, replication frequency, as well as the retention period for replicated backups.

In summary, Cisco HyperFlex with Cohesity DataProtect has built-in workflows that enable easy workload failover and failover testing. At the point where reverse replication can be initiated, a simple policy modification is all that is required. Cohesity also features Helios, a centralized management facility that enables the entire solution to be managed from a single web-based console.

Cisco Nexus 9000 Intelligent Buffers in a VXLAN/EVPN Fabric

As customers migrate to network fabrics based on Virtual Extensible Local Area Network/Ethernet Virtual Private Network (VXLAN/EVPN) technology, questions about the implications for application performance, Quality of Service (QoS) mechanisms, and congestion avoidance often arise. This blog post addresses some of the common areas of confusion and concern, and touches on a few best practices for maximizing the value of using Cisco Nexus 9000 switches for Data Center fabric deployments by leveraging the available Intelligent Buffering capabilities.

What Is the Intelligent Buffering Capability in Nexus 9000?

Cisco Nexus 9000 series switches implement an egress-buffered shared-memory architecture, as shown in Figure 1. Each physical interface has 8 user-configurable output queues that contend for shared buffer capacity when congestion occurs. A buffer admission algorithm called Dynamic Buffer Protection (DBP), enabled by default, ensures fair access to the available buffer among any congested queues.

Figure 1 – Simplified Shared-Memory Egress Buffered Switch

 

In addition to DBP, two key features – Approximate Fair Drop (AFD) and Dynamic Packet Prioritization (DPP) – help to speed initial flow establishment, reduce flow-completion time, avoid congestion buildup, and maintain buffer headroom for absorbing microbursts.

AFD uses in-built hardware capabilities to separate individual 5-tuple flows into two categories – elephant flows and mouse flows:

◉ Elephant flows are longer-lived, sustained bandwidth flows that can benefit from congestion control signals such as Explicit Congestion Notification (ECN) Congestion Experienced (CE) marking, or random discards, that influence the windowing behavior of Transmission Control Protocol (TCP) stacks. The TCP windowing mechanism controls the transmission rate of TCP sessions, backing off the transmission rate when ECN CE markings, or un-acknowledged sequence numbers, are observed (see the “More Information” section for additional details).

◉ Mouse flows are shorter-lived flows that are unlikely to benefit from TCP congestion control mechanisms. These flows consist of the initial TCP 3-way handshake that establishes the session, along with a relatively small number of additional packets, and are subsequently terminated. By the time any congestion control is signaled for the flow, the flow is already complete.

As shown in Figure 2, with AFD, elephant flows are further characterized according to their relative bandwidth utilization – a high-bandwidth elephant flow has a higher probability of experiencing ECN CE marking, or discards, than a lower-bandwidth elephant flow. A mouse flow has a zero probability of being marked or discarded by AFD.

Figure 2 – AFD with Elephant and Mouse Flows

For readers familiar with the older Weighted Random Early Detect (WRED) mechanism, you can think of AFD as a kind of “bandwidth-aware WRED.” With WRED, any packet (regardless of whether it’s part of a mouse flow or an elephant flow) is potentially subject to marking or discards. In contrast, with AFD, only packets belonging to sustained-bandwidth elephant flows may be marked or discarded – with higher-bandwidth elephants more likely to be impacted than lower-bandwidth elephants – while a mouse flow is never impacted by these mechanisms.

Additionally, AFD marking or discard probability for elephants increases as the queue becomes more congested. This behavior ensures that TCP stacks back off well before all the available buffer is consumed, avoiding further congestion and ensuring that abundant buffer headroom still remains to absorb instantaneous bursts of back-to-back packets on previously uncongested queues.

DPP, another hardware-based capability, promotes the initial packets in a newly observed flow to a higher priority queue than it would have traversed “naturally.” Take for example a new TCP session establishment, consisting of the TCP 3-way handshake. If any of these packets sit in a congested queue, and therefore experience additional delay, it can materially affect application performance.

As shown in Figure 3, instead of enqueuing those packets in their originally assigned queue, where congestion is potentially more likely, DPP will promote those initial packets to a higher-priority queue – a strict priority (SP) queue, or simply a higher-weighted Deficit Weighted Round-Robin (DWRR) queue – which results in expedited packet delivery with a very low chance of congestion.

Figure 3 – Dynamic Packet Prioritization (DPP)

If the flow continues beyond a configurable number of packets, packets are no longer promoted – subsequent packets in the flow traverse the originally assigned queue. Meanwhile, other newly observed flows would be promoted and enjoy the benefit of faster session establishment and flow completion for short-lived flows.

AFD and UDP Traffic

One frequently asked question about AFD is if it’s appropriate to use it with User Datagram Protocol (UDP) traffic. AFD by itself does not distinguish between different protocol types, it only determines if a given 5-tuple flow is an elephant or not. We generally state that AFD should not be enabled on queues that carry non-TCP traffic. That’s an oversimplification, of course – for example, a low-bandwidth UDP application would never be subject to AFD marking or discards because it would never be flagged as an elephant flow in the first place.

Recall that AFD can either mark traffic with ECN, or it can discard traffic. With ECN marking, collateral damage to a UDP-enabled application is unlikely. If ECN CE is marked, either the application is ECN-aware and would adjust its transmission rate, or it would ignore the marking completely. That said, AFD with ECN marking won’t help much with congestion avoidance if the UDP-based application is not ECN-aware.

On the other hand, if you configure AFD in discard mode, sustained-bandwidth UDP applications may suffer performance issues. UDP doesn’t have any inbuilt congestion-management mechanisms – discarded packets would simply never be delivered and would not be retransmitted, at least not based on any UDP mechanism. Because AFD is configurable on a per-queue basis, it’s better in this case to simply classify traffic by protocol, and ensure that traffic from high-bandwidth UDP-based applications always uses a non-AFD-enabled queue.

What Is a VXLAN/EVPN Fabric?

VXLAN/EVPN is one of the fastest growing Data Center fabric technologies in recent memory. VXLAN/EVPN consists of two key elements: the data-plane encapsulation, VXLAN; and the control-plane protocol, EVPN.

You can find abundant details and discussions of these technologies on cisco.com, as well as from many other sources. While an in-depth discussion is outside the scope of this blog post, when talking about QOS and congestion management in the context of a VXLAN/EVPN fabric, the data-plane encapsulation is the focus. Figure 4 illustratates the VXLAN data-plane encapsulation, with emphasis on the inner and outer DSCP/ECN fields.

Figure 4 – VXLAN Encapsulation

As you can see, VXLAN encapsulates overlay packets in IP/UDP/VXLAN “outer” headers. Both the inner and outer headers contain the DSCP and ECN fields.

With VXLAN, a Cisco Nexus 9000 switch serving as an ingress VXLAN tunnel endpoint (VTEP) takes a packet originated by an overlay workload, encapsulates it in VXLAN, and forwards it into the fabric. In the process, the switch copies the inner packet’s DSCP and ECN values to the outer headers when performing encapsulation.

Transit devices such as fabric spines forward the packet based on the outer headers to reach the egress VTEP, which decapsulates the packet and transmits it unencapsulated to the final destination. By default, both the DSCP and ECN fields are copied from the outer IP header into the inner (now decapsulated) IP header.

In the process of traversing the fabric, overlay traffic may pass through multiple switches, each enforcing QOS and queuing policies defined by the network administrator. These policies might simply be default configurations, or they may consist of more complex policies such as classifying different applications or traffic types, assigning them to unique classes, and controlling the scheduling and congestion management behavior for each class.

How Do the Intelligent Buffer Capabilities Work in a VXLAN Fabric?

Given that the VXLAN data-plane is an encapsulation, packets traversing fabric switches consist of the original TCP, UDP, or other protocol packet inside a IP/UDP/VXLAN wrapper. Which leads to the question: how do the Intelligent Buffer mechanisms behave with such traffic?

As discussed earlier, sustained-bandwidth UDP applications could potentially suffer from performance issues if traversing an AFD-enabled queue. However, we should make a very key distinction here – VXLAN is not a “native” UDP application, but rather a UDP-based tunnel encapsulation. While there is no congestion awareness at the tunnel level, the original tunneled packets can carry any kind of application traffic –TCP, UDP, or virtually any other protocol.

Thus, for a TCP-based overlay application, if AFD either marks or discards a VXLAN-encapsulated packet, the original TCP stack still receives ECN marked packets or misses a TCP sequence number, and these mechanisms will cause TCP to reduce the transmission rate. In other words, the original goal is still achieved – congestion is avoided by causing the applications to reduce their rate.

Similarly, high-bandwidth UDP-based overlay applications would respond just as they would to AFD marking or discards in a non-VXLAN environment. If you have high-bandwidth UDP-based applications, we recommend classifying based on protocol and ensuring those applications get assigned to non-AFD-enabled queues.

As for DPP, while TCP-based overlay applications will benefit most, especially for initial flow-setup, UDP-based overlay applications can benefit as well. With DPP, both TCP and UDP short-lived flows are promoted to a higher priority queue, speeding flow-completion time. Therefore, enabling DPP on any queue, even those carrying UDP traffic, should provide a positive impact.

Key Takeaways

VXLAN/EVPN fabric designs have gained significant traction in recent years, and ensuring excellent application performance is paramount. Cisco Nexus 9000 Series switches, with their hardware-based Intelligent Buffering capabilities, ensure that even in an overlay application environment, you can maximize the efficient utilization of available buffer, minimize network congestion, speed flow-establishment and flow-completion times, and avoid drops due to microbursts.
