Thanx for the reply ;)
I read somewhere that NFS is much slower than having an iscsi device.
Somewherelse they said the contrary....
What if I have a virtual openindiana server? should I zfs over an exported zfs
device?
Nooo...I don't think so....so NFS.
Is it good for cyrus/postfix and so on?
Then...what about a postgres db on NFS? and MySQL?
About windows.......should I boot on the iscsi disk? I don't think so...
What about SQLServer (...yes...people us it...) data files?...no way, just
iscsi or local disks....
It's a complete mess....backup is a mess here...
But I love ZFS :) that's why I brainstorm at 22:00 here :
If you have a ZIL or run the NFS share in async mode, the performance is
very good. I am running an all in one appliance. e.g. ESXi on a
quad-core xeon with 16GB ECC RAM. A virtual OI with 7GB of RAM and two
virtual cores. The OI VM runs on a small virtual disk on the ESXi local
datastore. 6 SATA drives in a 3/2 raid10 pool. The controller is
passed in to the OI VM via vmware vmdirectpath, so it has direct access
to the sata controller and drivers. A share on the pool is then
exported back to the ESXI itself. That NFS datastore is where all of
the other VMs live. Performance is very good.
