Its growth rate just got increased
IDC has increased the growth rate for InfiniBand in the 2007-2011 period due to accelerated InfiniBand take up.
An InfiniBand fabric has servers or storage devices connected to it by host channel adapters (HCA) and intervening InfiniBand switches. The current bandwidth is 20Gbit/s with 40Gbit/s just beginning – Mellanox has started shipping 40Gbit/s product – far beyond 10Gbit/s Ethernet or 8Gbit/s Fibre Channel.
IDC reckons that the compound annual growth rate (CAGR) for InfiniBand HCA shipments from 2007 to 2011 should be 51.5 percent, up from its previous 29.3 percent, with shipments reaching 991,878 in 2011 and HCA revenues reaching $279.7 million.
