HP 455880-B21 Hewlett-Packard HP ProCurve networking / enterprise server hardware Datacentre Switch

The HP 455880-B21 is a Virtual Connect Flex-10/10Gb Ethernet module built for the HP BladeSystem c7000 and c3000 enclosures (alternative part numbers 455882-001 cover the same module across HP’s parts catalogue), one of HP’s Virtual Connect interconnect modules that let a blade enclosure’s server NICs be provisioned and moved between physical uplinks in software rather than by re-cabling. Flex-10 technology partitions each 10GbE port into up to four independent FlexNICs with individually assignable bandwidth, so a single physical port can serve the roles that would otherwise need several separate NICs and cables. It occupies one of the enclosure’s interconnect bays and is typically deployed in a redundant pair for high-availability blade networking. As c-Class BladeSystem installations age, a spare or replacement Virtual Connect module is a routine requirement for restoring interconnect redundancy. Tech-Star (UK-based, shipped worldwide) supplies Virtual Connect modules for ongoing BladeSystem maintenance.
