Product Overview

The Cisco Unified Computing System (Cisco UCS®) is a next-generation data center platform that unites computing, networking, storage access, and virtualization resources in a cohesive system designed to reduce total cost of ownership (TCO) and increase business agility.

Using ultra-low latency Fusion ioMemory technology, the Fusion ioDrive2 adapter built for Cisco UCS C-Series Rack Servers decouples storage performance from capacity through the integration of a powerful new memory tier uniquely designed to accelerate application delivery.

Main Benefits

The Cisco UCS Fusion ioDrive2 Adapter (Figure 1) offers the following main benefits:

   Significant improvements in application performance for Cisco UCS C-Series servers: Fusion ioMemory significantly reduces latency in enterprise applications with a persistent, high-performance, high-capacity memory tier. This memory tier integrates transparently with Cisco UCS rack servers to immediately improve performance and relieve I/O bottlenecks.

   Dramatically reduced TCO: With significant performance improvements, Cisco® customers can reduce the amount of physical infrastructure that they need to deploy, increase the number of virtual machines that they can place on a single physical server, and further improve overall system efficiency. These improvements provide savings in capital expenditures (CapEx) and operating expenses (OpEx), including reduced application licensing fees and savings related to space, cooling, and energy use.

   Improved enterprise reliability through self-healing features, wear management, and predictive monitoring: The Cisco UCS Fusion ioDrive2 Adapter includes powerful features to eliminate concerns about reliability, including NAND flash memory failures and excessive wear. The all-new intelligent, self-healing Fusion-io Adaptive Flashback feature provides complete chip-level fault tolerance, which enables the Cisco UCS Fusion ioDrive2 Adapter to repair itself after a single chip failure or a multichip failure without interrupting business continuity.

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 the Cisco Unified Data Center 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.
