I am hoping that I can be giving some direction. I currently have two Dell Power Edge 2970 Servers running ESXi 4.0. I want to implement a third party backup solution (currently looking at PD Virtual or Veeam) and need to purchase an additional storage medium to store the backups that are created (currently using Ghetto script to snapshot each machine every night and placing it on the ESXI host machine). We are a small company of around 50 users and I do not have it in the budget to purchase a fiber SAN. I was looking at either a product from Buffalo or Thecus. Wanted to see what others are implementing on their networks.
