OK, I am new to the ZFS data storage thing and have a few questions, and yes I have googled it before asking, sizes rounded up for easy math
-Unit is mainly used for storage, will be accessed over a 2x1Gbps Bonded addapter, to upto 10 machines, but 5 mostly, (2 XBMC units, 1 laptop, and 2 destops)
-also i currently running ubunutu + zfs, would it be better to run ESXi + zfs os + ubunutu instead?
-Raidz vs Raidz2 and Raidz3, is there much overhead and will it hamper and VMs i have stored on those partions. I know it can be done, but I found no real specs on how much of an issue it was. Should i just setup a raid 0 with 2 500GB blue disk and backup to the raidz array, or can i run dirrectly off the zfs.
-setting up a zpool, is is possible to blend multiple Raidz levels into one large pool like you can with LVM2 (example raidz 8x2Tb (14TB), and raidz2 8x1.5TB (9TB), in one large pool for 23 TB of storage
-zfs, I currently have 14 2TB disk I am getting 3 more soon for a total of 17 2TB, all data on these disk is backed up to individual 750gb-1TB disks, how should i setup my raid pools, since these disk are all mixed I think of a few different setups. I think that the data is important but since it is all backed up I am not too worried about it failing, as I have run a 8x2TB LVM2 Spanned with no raid for over 2 years with out issue. I plan on using these 8 disk in my new build.
1=17x2TB in Raidz for about 32TB of usable storage + 1 Hot Spare added later.
2=17x2TB in Raidz2 for about 30TB of usable storage
3=17x2TB in Raidz3 for about 28TB of usable storage
4=9x2TB Green 5400 RPM disk Raidz +8x2TB regular 7200 RPM in Raidz + Shared hotspare to be added later. gives me about 30 TB of usable space. does mixing 5400 and 7200 RPM disk have a huge impact on transfers.
here is my rig specs.
