With 32 drives you should have at least 3 failure tolerances. Might even want to plan some hot spares in there. The idea is to build a large file system that won't die and take your data with it - nor introduce downtime (with a suitable failure tolerance). And of course, have an offsite backup for actually backing up your data.
- ChuckMcM 8y agoAgreed with the hot spare. Typical RAID reconstruction on these systems is limited to available I/O operations (IOPS) after accounting for the number needed to meet performance goals. If these are the only drives on a fairly beefy system you have lots of extra IOPS available so you should be able to reconstruct a drive in under a day if you wanted to. There are the usual caveats about age related failures happening in groups but at least anecdotally and from what I know from the folks who work in NetApp customer support usage across a much larger population, it is quite reliable.
