The V6XD series, has a new spin off the V6XDG+
4x Xeon compute nodes
4x GPU slots
10GbE internal connections
1x node 0 for user interface / control
Not only a great dev and sales tool, but also a rugged work horse for 'on-site' auditing / security / compliance etc!
Fly to the location (note the V6XD Series is small enough to go in cabin luggage), roll in the server, remove from flight case, plug in (2x 10GbE external ports) to gather your data, process you data (lots of RAM and power on hand), use the internal 'node0' for your user interface if required. Once you have finished securely wipe the client data from the internal SSDs (>16TB available), and move on to the next task - it couldn't be any easier!
