Products and services
Xsigo Systems' product, the I/O Director, is a hardware and software device that consolidates data center infrastructure and streamlines server I/O management. Using the Xsigo I/O Director, users provision I/O resources on live servers, without disrupting network and storage configurations, and without physically entering the data center. Xsigo’s I/O virtualization solution replaces a server’s multiple Ethernet and Fibre Channel interfaces with a single high-speed Ethernet or InfiniBand link. Multiple virtual Ethernet interfaces (vNICs) and virtual Fibre Channel interfaces (vHBAs) communicate over this link. Virtual interfaces are established using Xsigo’s virtualization hardware and Xsigo’s host drivers. These virtual I/O resources appear to the server’s applications like their traditional I/O card-based counterparts but unlike traditional I/O resources, vNICs and vHBAs can be created as needed and do not require the server to be opened or rebooted.
Xsigo awards and achievements include The Wall Street Journal Technology Innovation Award in the Network / Internet Technologies category, being named Storage Magazine's Product of the Year in the networking equipment category; also being identified by Byte and Switch as a Top 10 Storage Startup to Watch; also being named by Virtualization Review Magazine as Take Five: Innovative Vendor; and being identified by eWeek as a Top 10 Disruptive New Storage Technology. Xsigo Systems' VP780 I/O Director was also nominated for SYS-CON's Virtualization Journal Readers' Choice Awards for Best Network Virtualization.
