Solaris, as of 10u6 (released in October 2008), and recent versions of OpenSolaris and Solaris Express Community Edition on which OpenSolaris is based, can use SSD drives as a performance booster for ZFS. There are two available modes—using an SSD for the ZFS Intent Log (ZIL), which is used every time a synchronous write to the disk occurs, or for the L2ARC (Level 2 Adaptive Replacement Cache), which is used to cache data for reading. When used either alone or in combination, large increases in performance are generally seen. soprwisostdr If you need help with ordering or configuring your system call: © 2011 Ames Sciences, Inc.
