Greetings, I have a N54L Proliant Microserver I've been using that runs a linux software RAID1 with two 1 TB drives at home. I'd like to fill up the remaining next two bays with 1 TB drives for more space and additional redundancy (aiming for two drive failure). Performance is not a huge factor as it is a home server (I say this as the four bays use a port multiplier, not a raid card). The OS runs on a separate drive and SATA channel (so, 5 total SATA drives are possible), perhaps it's worth doing 5 1 TB drives and throw the OS into the mix? That said, I attended last years presentation on ZFS, and have even played around a little with thumb drives and Linux on ZFS with no issues. The server supports ECC, however I already purchased the RAM for it as non-ECC and 16 gigs worth, so I'd hate to throw away that investment to purchase more expensive ECC. Is it worth considering even using ZFS on Linux with non-ECC? The presentation leaned toward no, and that is the general consensus I'm seeing on forums. So, perhaps stick to a software Linux raid6? Here are are my wants: * Rock solid reliability and data integrity; I back up to Crashplan via headless nightly, but would like to minimize any dependency on this * Needs to survive the rare, but inevitable power failure; perhaps a UPS or other recommendations? * Must be able to have minimum 2 drive failure * Snapshots would be nice * Support for encryption would nice, which the software raid option gives me, am familiar with setting up LUKS Based on a lot of recent tests, I'll probably go with Western Digital drives for the cost savings and longevity, unless anyone has other suggestions? Thanks in advance for any suggestions, -- Jeremy MountainJohnson Jeremy.MountainJohnson at gmail.com
