Server Racks from Kneurr (or Knurr)

For the new server room, the method chosen for the most efficient use of the cooling equipment installed is "cold-aisle containment". For this to be effective, the racks used to house the servers need to be uniform. For that reason, it was decided that racks purchased from a specialist who could repeat the order over a period of time would be mandatory. The racks chosen were from Kneurr (or Knurr). The details are;

Miracel Server Rack 42U x 600W x 1000DP

Cage nuts (M5 (type 2) plate 2.5mm part no: 050415187)
Bolts to suit (Oval head screw part no: 050413319)
1U blanking plates (1U 19” Quick Release Blanking Panel (incl fixings) Part No: M119QRBP )

For “cold-aisle containment”, a minimum of 2 racks are needed (see here and here) and if you cannot fill the racks, blanking plates must be used to fill the empty spaces to maintain the separation of the cold air from the hot.
