The technology behind it;
We use 6 Dell PowerEdge 1950 servers with Windows Server 2003 and Flash Media Server 3.5, each connected with two gigabit connections to the HEAnet network. The Windows Media servers (soon to include the FMS servers) are Dell PowerEdge R905 servers with 10 Gbit/s connections running Windows Server 2008 R2 with Hyper-V. The servers currently host four virtual machines serving Windows Media using network load balancing across the VMs. They will soon host FMS VM also.
