New servers usually mean Fibre Channel (FC) host bus adapters (HBAs) for SAN traffic and Ethernet cards for NAS traffic. But I/O virtualization, or virtual I/O, changes that assumption. "Virtual I/O allows servers to connect to a multitude of different targets irrespective of the protocol," says Patrick Guay, senior VP of marketing at Voltaire, a provider of virtual I/O routers in Billerica, MA. To accomplish this, the virtual I/O router performs a "network address translation [NAT]-like function," says Bill Erdman, director of marketing at Cisco Systems' Server Virtualization Business Unit.

Cisco finds that virtual I/O offers organizations the following benefits: It creates a pool of physical HBAs and network interface cards (NICs) that may be shared between servers. It eliminates the need to install and cable HBAs and NICs for each server. It breaks the physical 1... Access >>>
