The Dell 1950 III is a fine server, but today I discovered a weakness, and something I hadn't known.
The weakbess is that if you use the built-in SAS controller with a 3tb drive, it can only see 2096 gb, just over 2tb. That's a weakness in common with other similar controllers I've used - it's annoying.
The thing I hadn't known, is that you can use an ordinary SATA drive with a SAS interface. It just plugs straight in, even though the plug and socket look quite different. Nice!
So instead of using a fast (15k) SAS drive at 147 gb for the system drive with a 3tb drive for data, I'm using two 2tb drives, raided and striped for a bit more speed.
This is because I'm setting up a new server to be the backup of my main server. The existing backups of that server will be dowgraded to just data backups; the new server will be used as an instant-swap replacement for the main server if anything terrible should happen to it.
