Howdy. My plan:
I'm planning an ESX-iSCSI target/NFS serving box. I'm planning on using an Areca RAID card, as I've heard mixed things about hot-swapping with Solaris/ZFS, and I'd like the stability of a hardware RAID. My question is this: I'll be using 8 750GB SATA drives, and I''m trying to figure out the best method to maintain: 1) Performance 2) Hot-swap-ability 3) Disk loss. My current plan is to build two RAID-5 arrays, 4 drives each, and mirror them in ZFS and add them to the pool. This will give me 750GB*3, size wise, total. Now, here is the important question: Does mirroring provide a performance boost, or is it simply a way to provide redundancy? That is, if I go ahead and force-add the RAID-5 arrays, without mirroring them, I'll have 6 usable drives; double the storage, but ZFS won't see any redundancy. But if a drive fails, ZFS won't know or care, I'll simply go into the Areca control panel and eject the drive; voila! But, is there a performance boost with mirroring the drives? That is what I'm unsure of. Thanks for any information!
