BladeSystem

BladeSystem is a line of blade server machines from Hewlett Packard Enterprise (Hewlett-Packard before 2015) that was introduced in October 2004.

The BladeSystem forms part of the HP Converged Systems, which use a common converged infrastructure architecture for server, storage, and networking products. Designed for enterprise installations of 100 to more than 1,000 Virtual machines, the HP ConvergedSystem 700 is configured with BladeSystem servers. When managing a software-defined data center, a System administrator can perform automated lifecycle management for BladeSystems using HP OneView for converged infrastructure management.

The BladeSystem allows users to build a high density system, up to 128 servers in each rack.

Currently HP offers 2 types of enclosures in its BladeSystem lineup.

HP c7000 enclosure was announced in June 2006. In 2007 there was a minor update including larger Onboard Administrator display (3 inches, up from 2 inches). The next update was in 2009 and brought RoHS compatibility, increased backplane speed (5Tbit/s, up from 4Tbit/s) and 1Gbit/s Onboard Administrator connectivity. Fourth version – c7000 Platinum was announced in February 2013. It features location discovery services, thermal discovery services and redesigned backplane. The new backplane increased aggregate bandwidth 40% from 5 to 7 Tbit/s to allow use newest high-speed interconnect modules (such as 16Gbit/s FC and 56Gbit/s FDR InfiniBand). Also the new Platinum Plus rating power supplies were announced with higher efficiency than previous Gold Plus rating power supplies.

All versions of the enclosure occupy 10 rack units and can accommodate up to 16 half-height blade servers. It includes space for 6 power supplies (single-phase, three-phase or a −48V DC), 10 cooling fans, 8 single-wide (such as Gigabit Ethernet or FC) or 4 double-wide (such as 40Gb Ethernet or Infiniband) interconnect modules (that allows for up to 4 redundant interconnect fabrics)
