Modernizing your data lake to the evolving landscape

In today’s environment, voluminous amount of data, reaching exabytes in scale, ends up being stored in a data ecosystem. Enterprises are constantly evaluating new sets of data management for processing, transforming, and analyzing these large amounts of data, leading to newer data pipelines that are evolving beyond the standard data lake.

The rapid advancement of Artificial Intelligence and Machine Learning (AI/ML) introduces a new set of challenges to the business and the IT organization’s data strategy when implementing high-performance, scalable, and agile-fashion cloud-scale architecture.

The next generation of distributed systems for big data analytics needs to address data silos between different tiers such as data lakes, data warehouses, AI/compute, and object storage. It is imperative to develop an infrastructure that sustains a healthy data pipeline between storage devices and computing devices (CPU, GPU, FPGA). Also, reducing network bandwidth and achieving overall low latency for parallel data processing is critical for supporting an organization’s data-driven goals.

Cisco® Data Intelligence Platform (CDIP) is a cloud-scale architecture that brings together big data, AI/compute farms, and storage tiers to work together as a single entity while also being able to scale independently to address the IT issues in the modern data center.

Cisco Data Intelligence Platform

The Cisco Data Intelligence Platform (CDIP) supports today’s evolving architecture for big data analytics. CDIP combines a fully scalable infrastructure with centralized management and a fully supported software stack (in partnership with industry leaders) to each of three independently scalable components of the architecture: the data lake, AI/ML technologies, and object stores.

Hadoop 3.0 introduced Docker support along with GPU isolation and scheduling. This opened up a plethora of opportunities for modern applications, such as micro-services and distributed applications running on thousands of containers to execute AI/ML algorithms on petabytes of data with ease and in a speedy fashion. CIDP is fully capable of addressing those application needs managed by either YARN or Kubernetes.

As the journey continues in the Hadoop ecosystem, more staggering and impressive frameworks and technologies, such as Apache submarine and Spark 3.0, are available to further complement it. Along with these new technologies, CDIP offers an extremely adaptable architecture and it evolves as underlying technologies, the platform, and frameworks changes, providing total investment protection. Figure 1 shows an overview of the CDIP architecture.

CDIP delivers world-record performance

Cisco recently published five Hadoop performance world records on Cisco Data Intelligence Platform using TPCx-HS, an industry standard and leading benchmark for Hadoop throughput with both MapReduce and Spark.

By running different scale-factor workloads with Spark (1 TB, 3 TB, and 10 TB) and with MapReduce (1 TB, 3 TB, and 10 TB), we can demonstrate that Cisco Data Intelligence Platform is not only a leader in performance; it also scales linearly.

CDIP Highlights

Intelligent multi-domain management with Cisco Intersight

Cisco Intersight® enables IT to operationalize heterogenous infrastructure and the application platform at scale to seamlessly function as a single cohesive unit through single-plane-of-glass management.

Powered by the latest generation in CPU from Intel and AMD

The latest generation of processors from Intel (Cascade Lake Refresh) and AMD (EPYC 7002 series) provides the foundation for powerful data center platforms with an evolutionary leap in agility and scalability.

Elimination of infrastructure silos with CDIP

CDIP is a highly modular platform that brings big data, AI compute farms, and object storage to work together as a single entity, while each component can scale independently to address the IT issues in the modern data center.

Disaggregated architecture

CDIP is a disaggregated architecture that brings together a more integrated and scalable solution for big data analytics and AI. It is specifically designed to improve resource utilization, elasticity, heterogeneity, and failure handling. It can also consume continuously evolving AI/ML frameworks and landscapes.

Pre-validated and fully supported

Cisco Validated Design (CVD) facilitates faster, more reliable, and more predictable customer deployments by providing configuration and integration of all components into a fully working optimized design. CVDs also provide scalability and performance recommendations.

Scaled architecture with 3:1 oversubscription with Cisco UCS Fabric Interconnects and Cisco ACI

The architecture discussed here and shown in Figure 14 supports 3:1 network oversubscription from every node to every other node across a multidomain cluster (nodes in a single domain within a pair of Cisco fabric interconnects are locally switched and not oversubscribed). The Cisco Nexus 9508 Switch with the Cisco N9K-X9736C-FX line card can support up to 36 x 100-Gbps ports each and 8 N9K-X9736C-FX line cards.

From the viewpoint of the data lake, 24 Cisco UCS C240 M5 Rack Servers are connected to a pair of Cisco UCS 6332 Fabric Interconnects (with 32 x 40-Gbps throughput). From each fabric interconnect, 8 x 40-Gbps links connect to a pair of Cisco Nexus 9336 Switches. Three pairs of fabric interconnects can connect to a single pair of Cisco Nexus 9336 Switches (8 x 2 40-Gbps links). Each of these Cisco Nexus 9336 Switches connects to a pair of Cisco Nexus 9508 switches with 6 x 100-Gbps uplinks (connecting to a Cisco N9K-X9736C-FX line card). Figure 14 provides a layout of the infrastructure.

Scaled architecture with 3:1 oversubscription with Cisco fabric interconnects and Cisco ACI

Figure 14.         

Scaled architecture with 3:1 oversubscription with Cisco fabric interconnects and Cisco ACI

Scaled architecture with 2:1 oversubscription with Cisco ACI

In the scenario discussed here and shown in Figure 15, the Cisco Nexus 9508 Switch with the Cisco N9K-X9736C-FX line card can support up to 36 x 100-Gbps ports each and 8 N9K-X9736C-FX line cards.

For the 2:1 oversubscription, 30 Cisco UCS C240 M5 Rack Servers are connected to a pair of Cisco Nexus 9336 Switches and each Cisco Nexus 9336 connects to a pair of Cisco Nexus 9508 Switches with three uplinks each. A pair of Cisco Nexus 9336 Switches can support 30 servers and connect to a spine with 6 x 100-Gbps links on each spine. This single pod (a pair of Cisco Nexus 9336 Switches connecting to 30 Cisco UCS C240 M5 servers and 6 uplinks to each spine) can be repeated 48 times (288/6) for a given Cisco Nexus 9508 Switch and can support up to 1440 servers.

To reduce the oversubscription ratio (to get 1:1 network subscription from any node to any node), you can use just 15 servers under a pair of Cisco Nexus 9336 Switches and then move to Cisco Nexus 9516 Switches (the number of leaf nodes would double).

To scale beyond this number, multiple spines can be aggregated. Figure 15 provides a layout of the scenario.

Conclusion

Evolving workloads need a highly flexible platform to cater to various requirements, whether data-intensive (data lake) or compute-intensive (AI/ML/DL) or just storage-dense (object store). An infrastructure to enable this evolving architecture—one that is able to scale to thousands of nodes—requires strong attention to operational efficiency.

To bring in seamless operation of the application at this scale, one needs:

      An infrastructure automation with centralized management

      Deep telemetry and simplified granular troubleshooting capabilities

      Multi-tenancy for application workloads, including containers and micro-services, with the right level of security and SLA for each workload

Cisco UCS with Cisco Intersight and Cisco ACI can enable this next-generation cloud-scale architecture, deployed and managed with ease.
