Imagine 10 SATA discs in raidz2 and one or two SSD drives as a cache. Each Vista client reaches ~90MB/sec to the server, using Solaris CIFS and iSCSI. So you want to use iSCSI with this. (iSCSI allows ZFS to export a file system as a native SCSI disc to a desktop PC. The desktop PC can mount this iSCSI disk as a native SCSI disk and format it with NTFS - on top of ZFS with snapshots, etc. This is done from desktop PC bios).
Now, you install WinXP on the iSCSI ZFS volume, and clone it with a snapshot. Then you can boot from the clone, with the iSCSI volume on a desktop PC. Thus, your desktop PC doesnt need any hard drive at all. It uses the iSCSI volume on the ZFS server as a native SCSI disk, which has WinXP installed. This way, you can deploy lots of desktop PC in an instant. Using the cloned WinXP snapshot. And if there are problems e.g virus, just destroy the clone and create a new one in one second. Has anyone does this? Does the SSD provide extra speed? Any stories to share? (Ive read this iSCSI suggestion on a blogg with black background color, it's not my idea). If I add a SSD disk as a cache, can I remove it? No? Will there be problems if I remove it? Can I exchange it with a bigger?
