I ended up purchasing an additional 2 TB of disk space for our SAN. In fact, the SAN that we were using was almost full so I had to buy a new SAN to hold the new disk space. I also purchased a new server for our ETL box. Our original box was an older Compaq DL360 G4P with 4X Intel Xeon 3.4 GHz CPUs and 4 GB of RAM.
We're still using the original box, but it will finally be replaced here this month. We're replacing it with a DL360 G6 with 32 GB of RAM. I'm not sure about the CPUs, but the server is going to be a much better box for our ETL.
Well, that's it. Nothing too exciting, but this is what we used our budget for.
