Solaris 11 Express 2010.11 and ZFS

Solaris 11 Express 2010.11 and ZFS

There was much discussion over the years over the discontinuance of Solaris Express distribution, the creation of OpenSolaris distribution, the discontinuance of OpenSolaris distribution, and ultimately the re-announcement of Solaris Express distribution. More information regarding Solaris Express has been leaked.

Designated Release:
It appears that there will be a release of Solaris Express referred next month or so, designated as Solaris 11 Express 2010.11!

RAID-Z/Mirror Hybrid Allocator:
Mirrored layout across the children of a RAID-Z vdev to ensure latency sensitive metadata can be read in a single I/O. See bug 6977913 reference.

ZFS "zdb" Enhancements:
Support for decompression, checksumming, and RAID-Z in "zdb" has been requested since 2008-Q4. See bug 6757444 reference.

ZFS File System Listing Enhancement:
Performance has been improved for listing ZFS file systems.

ZFS Encryption:
During 2003, a request was made to include encryption in ZFS, a welcome addition for laptops. The bug-id for this feature is 4854202.

Future Solaris 11 Support:
Solaris 11 is expected to power the new generation of embedded systems from Oracle including Exadata X2-8 database machine and Exalogic cloud-in-a-box!

There is more than this in the next release to come, but this gives us a clear direction of where we are at and where we are going!
