Hello,
I have been reading a lot about iSCSI lately so i decided to give it a try. I am runing FreeNAS 8.3.1 and have created iSCSI targets for mounting on ESXi 5.1. I have been running NFS + ZFS for about a year and had no issues however i am bored and wanted to do some benchmarks comparing the two.
Currently i have iSCSI + UFS (i heard ZFS requires lots of tweaking to run properly with iSCSI)
My question is how to do proper configuration on this, currently i have created a target for each VM that i have (5 of them) all with 100GB extents. Is it better to simply make 1 target using all of the UFS disk space and make say a 1TB extent and mount this in ESXi, then simply create the VM's off that datastore?
Backups, with UFS what is the best way to backup my extents / targets? should i just use ZFS, make the tweaks and use snap shots, saving the snap shots on a separate volume?
Can i just backup the extent? when i was using ZFS + NFS i could simply backup the directory the ESXi created for the VM, move it around all i wanted and was always able to import it back into esxi. with iSCSI how would i do that? backup the extent? then import when needed.
Little confused on the iSCSI stuff in regards to backups, and can not seem to find much in here via search function.
any info would be appreciated.
Thanks!
