I fully agree with your post. NFS is much simpler in administration.
Although I don't have any experience with the DDRdrive X1, I've read and heard
from various people actually using them that it's the best available SLOG
device. Before everybody starts yelling ZEUS or LOGZILLA. Was anybody
Yes, the sandforce based ssd's are also interesting. I think both, the 1500
sure can, could be fitted with the necessary supercap to prevent dataloss in
case of unexpected power loss. And the 1500 based models will available with a
SAS interface needed for clustering. Something the DDRdrive
Don't waste your time with something other than the DDRdrive for NFS ZIL. If
it's RAM based it might work, but why risk it and if it's an SSD forget it. No
SSD will work well for the ZIL long term. Short term the only SSD to consider
would be Intel, but again long term even that will not work

I wasn't planning to buy any SSD as a ZIL. I merely acknowledged that an
sandforce with supercap MIGHT be a solution. At least the supercap should take

This is not entirely correct either. You're not forced to use VMFS.
It is entirely true. You absolutely cannot use ESX with a guest on a block
device without formatting the LUN with VMFS. You are *FORCED* to use VMFS.
You can format the LUN with VMFS, then put VM files inside the VMFS;
Actually, this brings up a related issue. Does anyone have experience
with running VirtualBox on iSCSI volumes vs NFS shares, both of which
would be backed by a ZFS server?
