1 high density cooling solutions 2 a “blade” is a “server on a card”; containing processors, memory, hard drives, integrated ethernet nics, optional fibre channel hbas, hardware management operation and other i/o technologies. the first commercial blade servers were launched in 2001 by rlx technologies (bought by hp in 2005) what is a “blade server”? 3 the blade servers are plugged in to a chassis which provides shared infrastructures such as power, cooling, server management, kvm switches, etc. they are “hot-pluggable”. each chassis normally occupies “7u” of a “standard” 42u rack. therefore 1 rack can house up to 6 chassis. the “blade chassis” 4 modular scalabilitysimply slide new blade into vacant slot, no cabling versatilityblades with different types and speeds of processor can be mounted in the same chassis performancemany more servers can be packed into the same space availability and “hot swap” serviceability management and integrated systems management deploymentprocessors, minimal cabling blade server benefits 5 manufacturer total server market share blade server market share ibm38.4%42.7% hewlett packard26.8%35.1% dell9.6%11.2% source: idc feb 2006. based on 2005 4th quarter factory revenue manufacturers 6 total server market blade server market world market 4th quarter 2005 $14,478 million $667 million (4.6%) world market growth v q4 2004 -0.2%+56.9% emea market 4th quarter 2005 $4,927 million?
