Data Center Overview

The need to analyze growing amounts of data, to support complex simulations, to overcome performance bottlenecks and to create intelligent data algorithms requires the ability to manage and carry out computational operations on the data as it is being transferred by the data center interconnect. NVIDIA Networking InfiniBand solutions incorporate In-Network Computing technology that performs data algorithms within the network devices, delivering ten times higher performance, and enabling the era of “data-centric” data centers. By delivering the fastest data speed, lowest latency, smart accelerations and highest efficiency and resiliency, InfiniBand is the best choice to connect the world’s top HPC and artificial intelligence supercomputers.

Server Virtualization

Increased density of virtual machines on a single system within a data center is driving more I/O connectivity per physical server. Multiple 1 or 10 Gigabit Ethernet NICs along with Fibre Channel HBAs are used in a single enterprise system for data exchange. Such hardware proliferation has increased I/O cost, convoluted cable management, and caused loss of I/O slots. 25GbE and higher networking solutions with higher speeds that can run multiple protocols simultaneously (RoCE, iSCSI, etc.) can deliver better performance with unmatched scalability and efficiency. This helps reduce costs while providing the ability to support an increasingly virtualized and agile data center.

Controllerless Network Virtualization

Datacenter operators are now increasingly adopting controller-less network virtualization leveraging Ethernet Virtual Private Network (EVPN) with VXLAN. As the name suggests, there are no controllers involved in this approach. BGP – the same protocol that runs the internet is used to propagate MAC/IP reachability and build a highly scalable virtualized fabric. NVIDIA Networking Spectrum switches have comprehensive support for VXLAN overlays with 10X better scalability and rich feature set. With support for all flavors of VXLAN routing and concurrently with RoCE, Spectrum switches are the ideal building block for modern virtualized infrastructure.

Ethernet Storage Fabric

Ethernet is the dominant storage interconnect in the cloud. New storage technologies such as NVMe Over Fabrics have dramatically improved storage performance. Traditional Commodity Ethernet switches are incapable of consistently and predictably handling high bandwidth storage traffic. With support for high-bandwidth cut-through performance, compact form-factor and turn-key integration with major storage solutions, NVIDIA Networking Spectrum Ethernet switches are purpose-built and ideal for Ethernet Storage Fabric.

Scale-Out Databases

NVIDIA Networking high performance and low latency Ethernet and InfiniBand-based server adapters and switches provide fault-tolerant and unified connectivity between clustered database servers and native storage, allowing for very high efficiency of CPU and storage capacity usage. The result is 50% less hardware cost to achieve the same level of performance.

Microsoft Based Solutions

The efficiency of today's data centers depends heavily on fast and efficient networking and storage capabilities. Microsoft has determined that offloading the network stack processing from the CPU to the network is the optimal solution for storage hungry workloads such as Microsoft SQL Server, and Machine learning. Offloading frees the CPU to do other application processing, which improves performance and reduces the number of servers required to support a given workload, resulting in both CapEx and OpEx savings.

Whether looking for on premise data center or public cloud offerings, Microsoft‘s solutions combined with NVIDIA Networking networking with offload accelerators provides for a solid foundation to provide outstanding performance, and increased efficiency to accommodate evolving business needs. Turn-key Microsoft Based Solutions based NVIDIA Networking ConnectX adapters and Spectrum Ethernet switches are available through key OEM partners such as Dataon, SecureGuard and Fujitsu.

Virtualization

The data centers that today's IT professionals are asked to manage are more than just tools in a larger operation; they are critical to their company's business. For many, the data center is the business itself. It must deliver the best performance at the lowest possible total cost of ownership and scale as the business grows. As such, the majority of IT organizations have either already adopted or are in the process of adopting virtualization technologies. This enables a company to run various applications over the same servers, maximizing server utilization and achieving a dramatic improvement in the total cost of ownership, elastic provisioning, and scalability.

However, the adoption of a virtualization architecture creates some very significant data center interconnect challenges. To overcome these challenges, the majority of IT organizations are deploying advanced interconnect technologies to enable a faster, flatter, and fully virtualized data center infrastructure. Using the right interconnect technology, connecting servers to servers and servers to storage, reduces cost while providing the ability to support an increasingly virtualized and agile data center. This is exactly what NVIDIA Networking end-to-end interconnect solutions deliver.

Highest I/O Performance

NVIDIA Networking products and solutions are uniquely designed to address the virtualized infrastructure challenges, delivering best-in-class and highest performance server and storage connectivity to various demanding markets and applications, combining true hardware-based I/O isolation and network convergence with unmatched scalability and efficiency. NVIDIA Networking solutions are designed to simplify deployment and maintenance through automated monitoring and provisioning and seamless integration with the major cloud frameworks.

Figure 1: By using the ConnectX-3 40GbE adapter, a user can deliver much faster I/O traffic than by using multiple 10GbE ports from competitors.

Hardware Based I/O Isolation

NVIDIA Networking ConnectX® adapters and NVIDIA Networking switches provide a high degree of traffic isolation in hardware, allowing true fabric convergence without compromising service quality and without taking additional CPU cycles for the I/O processing. NVIDIA Networking solutions provide end-to-end traffic and congestion isolation for fabric partitions, and granular control of allocated fabric resources.

Every ConnectX adapter can provide thousands of I/O channels (Queues) and more than a hundred virtual PCI (SR-IOV) devices, which can be assigned dynamically to form virtual NICs and virtual storage HBAs. The channels and virtualized I/O can be controlled by an advanced multi-stage scheduler, controlling the bandwidth and priority per virtual NIC/HBA or group of virtual I/O adapters. This ensures that traffic streams are isolated and that traffic is allocated and prioritized according to application and business needs.

Accelerating Storage Access

In addition to providing better network performance, ConnectX's RDMA capabilities can be used to accelerate hypervisor traffic such as storage access, VM migration, data, and VM replication. The use of RDMA pushes the task of moving data from node-to-node to the ConnectX hardware, yielding much faster performance, lower latency/access-time, and lower CPU overhead.

In today's virtualized data center, I/O is the key bottleneck leading to degraded application performance and poor service levels. Exacerbating the issue is infrastructure consolidation and a cloud model mandate that I/O and network resources be partitioned, secured, and automated.

Accelerating Remote Storage Access - Breakthrough Performance, Scaling and Resiliency

The exponential growth and the availability of data forces organization to build and deploy infrastructure that enables their businesses to thrive in this new era. To meet these dynamic and growing demands Microsoft has released an advanced set of features introduced in Windows Server 2016 with support for Microsoft Azure Stack. Storage Spaces Direct (S2D) adds the concept of pooling affordable drives form shareable storage and also introduced RoCE (RDMA over Converged Ethernet) to access data without burdening the CPU. In doing so, they offer a new way to deploy scalable and cost-effective storage while offloading IO processing to the network. This increases the server‘s efficiency since the CPU becomes available to run applications, and thus reduces the number of servers required to support a given workload.

With NVIDIA Networking RoCE the performance of a Storage Spaces Direct implementations doubles and CPU burdens shrink, enabling significantly higher efficiency in Windows-based data centers. Data accessed over RoCE enable:

  • Increased throughput: leverages the full throughput of high speed networks in which the network adapters coordinate the transfer of large amounts of data at line speed.
  • Low latency: provides extremely fast responses to network requests, and, as a result, makes remote file storage feel as if it is directly attached block storage.
  • Low CPU utilization: uses fewer CPU cycles when transferring data over the network, which leaves more power available to server applications.

As enterprises move to public cloud offerings, they also recognize that certain workloads will remain on-premises, and need an easy and cost-effective solution to seamlessly connect these two worlds. Microsoft Azure Stack provides this in a hybrid cloud storage solution. With Azure Stack, organizations can achieve their goal of connecting traditional infrastructure to the Azure cloud. By utilizing the advantages of S2D and NVIDIA Networking RoCE enabled adapters and switches, Azure Stack provides more efficient and faster access to data and transforms enterprise data centers by boost performance and agility of enterprise applications.

Online Transaction Database

In recent years, clustering has become the technology of choice for database systems. It has proven to be the most efficient way to meet today’s business requirements: high performance, high-availability, and scalability at a lower cost of ownership. In order to achieve these goals it is critical to choose the right interconnect solution.

One of the most important parameters that a business process must meet is its Recovery Time Objective (RTO), which defines the maximum allowed downtime of a service due to failure. Not meeting RTO can result in the unacceptable consequences associated with a break in business continuity. As most enterprise applications use databases, RTO must also include the time required to restore the entire database. For example, the expected RTO for databases used in data warehouses is between 12 hours and a few days. However, this RTO range surely cannot apply to Online Transaction Processing (OLTP) systems, where the expected RTO is much more challenging and is in the order of minutes to a few hours, depending on the size of the database storage.

Recently, a tier-1 Fortune 100 Web2.0 company wanted to build a high performance database system that would be capable of handling tens of millions of mobile user requests per day in real time, while keeping the total cost of ownership intact.

The company's original database system was based on 1GE network technology, which presented a number of challenges: Scaling the architecture and technology infrastructure was expensive and time consuming; the company's ability to meet the demands of a near-real-time response to its mobile customers was limited; and, in case of database failure, it took them more than 7 days to restore the database system, which was extremely slow compared to their 6-hour goal. This brought the company to consider using a faster and more efficient interconnect technology that would enable the company to meet all these demands, while also cutting down the costs associated with maintaining the infrastructure.

Working jointly with NVIDIA Networking Solutions, a leading supplier of end-to-end connectivity solutions for data center servers and storage, a modular database clustered solution was developed that utilizes NVIDIA Networking end-to-end InfiniBand and Ethernet Technologies. The solution supports the deployment of a single database across a cluster of servers and provides superior fault tolerance, performance, and scalability without any need to change applications. The solution provides a near-real-time response for the mobile users and also a 4-hour recovery time, 33% faster than the company's target. In addition, it offers customer continuous uptime for all of its database applications, on-demand scalability, lowered computing costs, and record-breaking performance.
