Hardware RAID with ZFS on Nexenta (OpenSolaris)
Posted on 2013-01-06
I am using Nexenta (Open Solaris) for its ZFS features on an Appliance that I use. I was planning to set the disks as JBOD, but when I got down to it, the LSI MegaRaid SAS 8708EM2 controller did not support JBOD. So, I had to set each of the 24 1Tb SATA disks as its own single disk RAID0 configuration. This, at least, allowed the disks to be seen by the installation. I mirrored the boot disks and used zpool not the Nexenta menu to create a 3 x 6disk raidz3 configuration with 3 hotspares. The zpool will be used as an Iscsi target for remote VMware datastore. Is this an efficient configuration or how could this have been done better with Nexenta.? Thank you for your help!
