The Intel Cache Acceleration Software (CAS) is a computer data storage product for solid-state drive (SSD) caching.

Description

CAS manages using the SSD storage as a cache layer for slower storage data (e.g. spinning hard drives). A cached copy of recently used data from slower storage is kept in faster SSD storage to improve I/O performance.

Windows Enterprise, Windows Workstation, and Linux.[2][4]

CAS for Windows is an application-aware file-based cache, which can be tuned by system administrators. Additionally, it integrates with the operating system's

vMotion, maintaining a hot SSD cache during a VM migration.[7]

CAS works with the enterprise-class Intel SSD products, such as the

SUSE Linux Enterprise Server.[7] The Windows Enterprise version currently runs only on the 64-bit flavors of Windows Server 2008 R2 SP1 and Windows Server 2012 R2; 32-bit versions are not currently supported.[9]
The Windows Workstation version currently runs on only the 64-bit flavors of Windows 7, Windows 8.1, and Windows 10; 32-bit versions are not currently supported.

The current version of CAS for Linux supports write-through, write-back, and write-around caching. The Windows versions of CAS support

write-through and write-back caching.[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.[10][11]
