I''ve been reading about the work using flash SSD devices for ZIL and cache devices. I was wondering if anyone knows what releases of Opensolaris and Solaris these features are available on? The performance inporvements are pretty dramatic. Alastair -------------- next part -------------- An HTML attachment was scrubbed...

The > performance inporvements are pretty dramatic.You can keep track of some of the major updates through the flag days announcements: http://www.opensolaris.org/os/community/on/flag-days/all/ The separate ZIL log arrived in b68 (June 2007) and the L2ARC arrived in b78 (November 2007). Both will have made OpenSolaris 2008.05 which is based on b86. IIRC, Solaris 10u5 is based on b70. Both are planned to be in Solaris 10u6. -- richard
