Cache Acceleration Software

From Wikipedia, the free encyclopedia

The Intel Cache Acceleration Software (CAS) is an enterprise storage product for SSD caching.

CAS is an application-aware file-based cache, which can be tuned by system administrators. Additionally, it integrates with the operating system's buffer cache, creating a multi-tier cache architecture.[1][2] CAS is also aware of some vitalization technologies like vMotion, maintaining a hot SSD cache during a VM migration.[3]

CAS entered Intel's product line as the result of Intel's August 2012 acquisition of a Canadian start-up company Nevex Virtual Technologies;[4] Intel re-branded Nevex CacheWorks product to CAS with the release of version 2.0 in December 2012.[5]

CAS works with the enterprise-class Intel SSD products, such as the DC S3700 SATA drives and the 910-series PCI Express cards.[4] It also works with cache devices across SANs.[6] CAS is available on both Windows and — since February 2013 — on Linux.[7][4] There are two Linux flavors of CAS: the community version was announced to be GPL'd source, while the commercially supported version is available for CentOS, Red Hat Enterprise Linux and SUSE Linux Enterprise Server.[3] The Windows version currently runs only on the 64-bit flavors of Windows Server 2008 R2 and Windows Server 2012; 32-bit versions or desktop version of Windows are not currently supported.[8]

A workstation version, called CAS-W, was announced in September 2013 by Dell; Dell's announcement states an exclusive agreement with Intel to offer CAS-W only for Dell Precision workstations.[9][10]

The current version of CAS supports only write-through caching.[6]
