Modular scalability simply slide new blade into vacant slot, no cabling Versatility blades with different types and speeds of processor can be mounted in the same chassis Performance many more servers can be packed into the same space Availability and “hot swap” serviceability Management and integrated systems management deployment processors, minimal cabling IBM Each BladeCenter chassis occupies “7U” Max 6 BladeCenters in standard “42U” rack Max heat output per BladeCenter: 4kW Max heat output per rack: 24kW Nominal cooling airflow: 6 x 850 = 5100 m3/h Airflow front to back Dell 10 PowerEdge 1855 Blades occupy “7U” Max 60 PowerEdge 1855 Blades in standard “42U” rack Max heat output per 10 Blades: 4.17kW Max heat output per rack: 25kW Nominal cooling airflow: 6 x 680 = 4080 m3/h Airflow front to back Blade servers currently deployed are normally spread around a number of racks in the data centre Weight is also an issue – fully loaded rack is up to 900kg Actual heat loads are less than those predicted because all the servers in a rack are never fully loaded at the same time (perhaps why IBM and Siemens only offer max 15kW cooling solutions of their own) Cost of space is not the main driver for blade server deployment Manufacturers recognise that getting sufficient power and cooling to the servers is a constraint on the growth in deployment and are working on solutions Optimised management of the whole cooling system Reduction in energy consumption and running costs Maintaining optimum conditions during all operating phases Monitoring the room, the servers and all of the main system components with the possibility of remote assistance.
