This IDC Vendor Profile examines Xsigo and the launch of its new Xsigo VP780 I/O Director, a network appliance that replaces NIC and HBA cards tied to individual servers with a virtualized I/O fabric. It discusses the benefits of I/O virtualization, especially in terms of implementing a virtualized server environment; describes some of the advantages of the Xsigo approach to I/O virtualization; and provides insights from a financial services firm — currently evaluating Xsigo — that IDC interviewed for this Vendor Profile.
