Hi Nicholas, ZFS itself is very stable and very effective as fast FS in our experience. If you browse the archives of the list you'll see that NFS performance is pretty acceptable, with some performance/RAM quirks around small files:
http://www.opensolaris.org/jive/message.jspa?threadID=19858 http://www.opensolaris.org/jive/thread.jspa?threadID=18394 To my understanding the iSCSI driver is undergoing significant performance improvements...maybe someone close to this can help? If by VI you are referring to VMware Infrastructure...you won't get any support from VMware if you're using the iSCSI target on Solaris as its not approved by them. Not that this is really a problem in my experience as VMware tech support is pretty terrible anyway.
Some questions: 1. how stable is zfs? i'm tolarent to some sweat work to fix problems but data loss is unacceptable
We haven't experienced any data loss, and have had some pretty nasty things thrown at it (FC array rebooted unexpectedly).
2. If drives need to be pulled and put into a new chasis does zfs handle them having new device names and being out of order?
My understanding and experience here is yes. It'll read the ZFS lables off the drives/slice.
3. Is it possible to hot swap drives with raidz(2)
Depends on your underlying hardware. To my knowledge hot-swapping is not dependent on the RAID-level at all.
4. How does performance compare with 'brand name' storage systems?
No clue if you're referring to NetApp. Does anyone else know? -J _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
