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.〔(Nevex Speeds Apps With Caching System - InformationWeek )〕 CAS is also aware of some virtualization technologies like vMotion, maintaining a hot SSD cache during a VM migration.〔 CAS entered Intel's product line as the result of Intel's August 2012 acquisition of a Canadian start-up company Nevex Virtual Technologies;〔 Intel re-branded Nevex CacheWorks product to CAS with the release of version 2.0 in December 2012. CAS works with the enterprise-class Intel SSD products, such as the DC S3700 SATA drives and the 910-series PCI Express cards.〔 It also works with cache devices across SANs.〔 CAS is available on both Windows and — since February 2013 — on Linux.〔(Intel releases SSD cache acceleration software for Linux servers - Computerworld )〕 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.〔(Intel Cache Acceleration Software - YouTube )〕 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.〔http://www.intel.com/support/ssdc/cache/cas/sb/CS-033972.htm〕 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.〔(New Intel CAS-W: Accelerating Software Application Performance - Direct2Dell - Direct2Dell - Dell Community )〕〔(Intel Cache Acceleration Software with Dell and Autodesk - YouTube )〕 The current version of CAS supports only write-through caching.〔(Intel Cache Acceleration Software: FAQ Configuration and Use )〕 ==See also== *Intel Smart Response Technology for desktop-class computers *Microsoft's Automated Tiering (Windows 2012 R2) 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Cache Acceleration Software」の詳細全文を読む スポンサード リンク
