ZFS pools and SAS / SATA

S

Sylhouette

Hello.

We want to use an 24 Bays server as a storage box.
http://twp.nl/server-TWPSS1204887647 with an areca or LSI card.
the areca ca would be the 1880i
The LSI would be the 9211 8i

Now we have some relative static data (a lot) and we want to try VM ware machines served by ISCSI.

Now my thought was to create a raidz pool of 2 vdevs containing 6 SATA disks for the static data.
For the VMware ISCSI targets my idea was to make a mirrored pool of 2 vdevs contaning 2 SAS disks.

Is this possible, can i create Multiple pools on one machine, and can i mix SAS/SATA.

thanks
regards

Yes and not sure. It shouldn't be a problem provided that their sizes are the same (for mirror, raidz, etc.).
 
Here is multiple pools (ok, two of them):

SAS / SATA: sorry, I don't know. Haven't worked with SAS yet.
