Intel releases SSD cache acceleration software for Linux servers

Software migrates data between DRAM and SSD based on I/O intensity

Intel today released a version of its SSD-based Cache Acceleration Software (CAS) for Linux servers, which it said can offer up to 18 times the performance for read-intensive applications, such as on-line transaction processing systems.

Additionally, Intel's CAS now supports caching to NAND flash (solid-state drives and PCIe cards) in storage arrays. And it supports VMware vMotion, which allows virtual machines to migrate between systems while maintaining hot data on cache, regardless of the host machine.

"The advantage is not just to provide better performance, but ensure no matter what happens, that performance remains consistent," said Andrew Flint, Intel's CAS product manager.

Intel acquired its CAS technology in September from its buyout of Canadian startup Nevex. Nevex sold the software as CacheWorks, but Intel quickly rebranded it CAS.

The use of cache acceleration and management software for NAND flash memory is a hot market. More than a dozen vendors are shipping products, and acquisitions are on the rise. Earlier last year, SanDisk acquired FlashSoft for its flash cache acceleration and management software. That was followed by Samsung's buyout of Nvelo for its Dataplex SSD caching software. The software identifies data experiencing high levels of reads and moves it to NAND flash in the form of SSDs to boost performance.

Intel announced CAS support for Windows systems in December. The latest support, for Linux, also allows admins to select applications that will benefit from the higher performance SSDs or allow the CAS software to automatically redistribute I/O-intensive data to the flash memory.

Intel said its CAS product can target hot data on back-end storage, such as a SAN, for both Windows and Linux machines and allow virtual machine migration while maintaining high I/O performance with flash cache.

"We took the problem of the I/O bottleneck from the side of accelerating applications," Flint said. "We have technology to direct performance to applications. Because we do that, we find most of our sales are to the DBAs and the app admins at companies.
