Hi Chris,
We own the hardware and it is at a co-host location that has redundant internet trunks.
There's a SAN, and several hosts (Blade servers). All the VMs reside on the SAN, and they are instantiated on one of the hosts. There's a separate "performance storage" with SSDs in the SAN, and that's where the disk images for the storage servers live. The VMs are stored in regular HDD RAID storage on the SAN.
The SAN takes care a lot of the redundancy on site. However, I know there is an incremental backup created every 45 minutes which is transferred away from the cohosting site.

Thanks Tracy
So, you would typically have the clients RDP'ing into one server to run the .exe in turn accessing the dbf's on another VM acting as a file server?
How are the physical drives configured, is there any redundancy if anything fails or you using some VM magic?
Thanks
Chris.

Hi Chris,
We get away with 1 CPU core per server in a VM to get good performance accessing DBFs on a different VM. More CPU cores may help by allowing the server to spread out on additional cores. We don't see a lot of CPU usage per VM. The bottle neck appears to be IO access to the DBFs. With that said, we have over 20 machines that allow a Remote Desktop like connection and 5 separate storage VMs for our 4000+ clients.
The fastest drives you can get (SSD's are a good choice) and a good backup solution.
HTH, Tracy

Hi All
Just a general question ...
If you was choosing a server which would run a vfp application using standard dbfs as fast as possible for around 30 users (connected via remote desktop). What server would you choose to get the best performance?
Is it CPU's , Hard Drive Configuration, Memory etc ... we can assume that there is sufficient memory for the remote desktop side of things.
Thanks
Chris.
