Product Overview

With cost efficiency and a small footprint in mind, LSI 400GB SLC WarpDrive adapter (Figure 1), an LSI-powered PCI Express (PCIe) storage accelerator card, is fully supported on Cisco UCS® B-Series Blade Servers for a simple, ready-to-use solution. Using a high-speed PCIe bus, the LSI storage accelerator card stores performance-sensitive data directly on the server blade so that it is as close as possible to the application. This placement can dramatically improve application performance because the “hot data” is read directly from PCIe flash-memory storage residing on the server, bypassing the need to go to the storage network to access that data. This approach increases throughput and reduces latency while simultaneously lightening the workload on the rest of the infrastructure.

In addition, on the new LSI storage accelerator card, flash-memory management processing is run directly on the card, offloading server CPU processing and preserving valuable system memory, using up to 75 percent fewer CPU and memory resources than many other solutions on the market. This savings allows the server's valuable processing resources to be used more effectively for database processing.

The LSI 400GB SLC WarpDrive adapter is built on the latest enterprise-class solid-state technologies and includes sophisticated advanced features to help deliver consistently high levels of performance, endurance, and reliability under some of the most demanding conditions. The LSI DuraWrite technology helps optimize the number of program cycles to the flash storage, effectively extending the rated write endurance of the flash storage by 20 times or more compared to standard controllers. Other sophisticated algorithms and dedicated onboard hardware resources handle complex flash-memory management tasks such as garbage collection and wear leveling. These advanced features make the LSI adapter an excellent choice for accelerating your business applications.

The LSI 400GB SLC WarpDrive adapter has been integrated, tested, and certified with EMC XtremSW Cache and NetApp FlashAccel caching software. Cisco Unified Computing System (Cisco UCS) customers can confidently deploy an end-to-end solution with the LSI 400GB SLC WarpDrive adapter knowing that it works transparently with existing EMC and NetApp storage arrays deployed in the data center.

Why Cisco?

Cisco UCS continues Cisco’s long history of innovation in delivering integrated systems for improved business results based on industry standards and using the network as the platform. Recent examples include IP telephony, LAN switching, unified communications, and unified I/O. Cisco began the unified computing phase of our Data Center 3.0 strategy several years ago by assembling an experienced team from the computing and virtualization industries to augment our own networking and storage access expertise. As a result, Cisco delivered foundational technologies, including the Cisco Nexus® Family, supporting unified fabric and server virtualization. Cisco UCS completes this phase, delivering innovation in architecture, technology, partnerships, and services. Cisco is well positioned to deliver this innovation by taking a systems approach to computing that unifies network intelligence and scalability with innovative application-specific integrated circuits (ASICs), integrated management, and standard computing components.
