I just recently bought a new server an HP DL380 G6. I replaced the stock smart array p410 controller with an LSI 9211-8i.
My plan is use ZFS as the underlying storage for XEN which will run on the same baremetal.
I have been told that you can use SATA disks with the smart array controllers but because consumer drives lack TLER, CCTL and ERC its not recommended. Is this the case?
I was wondering if using the LSI controller in JBOD (RAID passthrough mode) does the kind of disks I use really have as much of an impact as they would with the smart array controller?
I am aware that trying to use a RAID system not backed by a write cache for virtualization is not good for performance. But I was conisdering adding an SSD for ZFS. Would that make any difference?
I reason I am so obsessed with using ZFS is for dedup and compression. I don't think the smart array controller can do any of those features.
