Dell PowerEdge M1000E Blade Server Teardown
I came by a discarded full size Dell PowerEdge M1000E server rack. Full SAN, 2 large blade servers, 4 or 6 backbone switches, all power supplies and fans. This is a system that is about 8-10 years old and had a new price of around 1000000 DKR (166666 $US).
It was all unloaded in a big mess into a container and I only had time/space to take a blade server, all power supplies and fans with me. Hard disks all go to destruction and backbone switches and the M1000E cabinet itself is too big and clumsy to have any real value in the work shop.
