I don't understand. How do you "setup one LUN that has all of the NVRAM on the array dedicated to it"
I'm pretty familiar with 3510 and 3310. Forgive me for being a bit thick here, but can you be more specific for the n00b? Do you mean from firmware side or OS side? Or since the LUNs used for the ZIL are separated out from the other disks in the pool they DO get to make use of the NVRAM, is that it? I have a pair of 3310 with 12 36-gig disks for testing. I have a V240 with PCI dual-SCSI controller so I can drive one array from each port is what I am tinkering with right now. Looking for maximum reliability/redundancy of course so I would ZFS mirror the arrays. Can you suggest a setup here? A single-disk from each array exported as a LUN, then ZFS mirrored together for the ZIL log? An example would be helpful. Could I then just lump all the remaining disks into a 10-disk RAID-5 LUN, mirror them together and achieve a significant performance improvement? Still have to have a global spare of course in the HW RAID. What about sparing for the ZIL?
