1 The 40% power savings was calculated by comparing a 1U server with a 450W power supply and IBM System x iDataPlex with a 375W power supply configured with dual-core low-voltage processors, 8 GB memory (4x2 GB) and four 500 GB SATA hard disk drives.
2 In most cases with the IBM Rear Door Heat eXchanger installed in the iDataPlex rack, outlet temperatures from the back of the iDataPlex rack are up to 10 degrees lower than inlet air (room) temperatures. This helps eliminate the need for air conditioning and facilitates cooling of the next row of iDataPlex racks using the iDataPlex flow-through layout.
