I was asked to come in and look at a companies server because it was having problems. The consultant they brought in to set it up originally is not answering their calls. It is an HP ML350. The first thing I noticed was there is only one hard drive installed. I am going to make a lot of changes, but I want to continue to use the ML350. This is their only server and they do not want to invest in a second at this time.
They are running MS Server 2008 with multiple apps, exchange, AD & as a file server. It is setup running a virtual server, but I do not know very much about that portion.
I want to setup Raid on this server now. I have not set this up after the server is in production before. Can I get some recommendations for the hardware and the type of Raid to setup? Any suggestions on the best way to accomplish this with the happy medium of redundancy, down-time, ease of installation/setup and reliability?
What am I missing?
