Has anyone bought one of these cards recently? It seems to list for around $170
at various places, which seems like quite a decent deal. But no well-known
reputable vendor I know seems to sell these, and I want to be able to have
someone backing the sale if something isn't perfect. Where do you

Need your help. My DEV134 OSOL build with my 30TB disk system got really

I added 3 drives to my pool with the intent to add them to my RAIDz2...

Thank you everyone for your answers.
Cost is a factor, but the main obstacle is that the chassis will only support
four SSDs (and that's with using the spare 5.25 bay for a 4x2.5 hotswap bay).
My plan now is to buy the ssd's and do extensive testing. I want to focus my

I want to transfer a lot of ZFS data from an old OpenSolaris ZFS mirror
(v22) to a new FreeBSD-8.1 ZFs mirror (v14).
If I boot off the OpenSolaris boot CD and import both mirrors will the
copying from v22 ZFS to v14 ZFS be harmless?
I'm not sure if this is teh right mailinglist for this question.

We are doing NFS in VMWare 4.0U2 production, 50K users using OpenSolaris
SNV_134 on SuperMicro boxes with SATA drives. Yes, I am crazy. Our experience
has been that iSCSI for ESXi 4.x is fast and works well with minimal fussing
until there is a problem. When that problem happens, getting to data

RAID-Z is limited to 3 parity disks. The error message is giving you false hope

I have a 8 disk raidz2 pool (ZP02) that I am having some issues with.
The pool is using WD20EADS 2TB drives connected to a Intel SASUC8I

The pool was originally created when the machine was running SXDE 1/08.
