and when it is, the odds of a 2nd drive failing are almost microscopic, so at a hardware level, a 3 or 4 drive RAID 5 is an acceptible risk. Again, if your data is valuable enough, invest in the extra drive(s) and use RAID 6 or even RAID 6 cascaded with RAID 1 'protection' of the entire array....what is that? Raid 60? Too many drives involved - we are limited to 4 drives per system. In that case use 4 x 15k SAS drives of moderate capacity as RAID6 combined with a good controller (IBM or 3Ware). If that doesn't provide a good enough compromise of 2 disk redundance and speed, you need an external storage.
Which is what I'm planning on getting rid off :-)
We don't need a lot of space - 1-2Tb in total will provide plenty of room for growth for a couple of years. Instead, reliability is paramount - we will quite probably be getting rid of the central SAN storage, and moving to a distributed model. A neat little 1U server like an HP DL160G5 has room for 4 SATA drives (or SAS with the right controller) - we're looking at getting a couple of that type (not necessarily the HP though).
Strange, we are currently considering to migrate on to a SAN environment. What is the reason for your move to single server storage and what kind of SAN do your use? -- Sandy List replies only please!
