Virtensys provides I/O virtualization appliances that simplify server connectivity and management. Their appliances consolidate physical networking and storage adapters into shared pools of virtual I/O resources. This allows datacenter administrators to easily provision and reallocate virtual network interface cards and host bus adapters across multiple servers from a centralized management console. Customers benefit from reduced complexity, costs, and time spent on routine I/O provisioning and management tasks.

20. A fewer number of high powered interfaces are virtualized within the Virtensys IOV Appliance

21. A simple, low power, low profile PCIe extender card is inserted into the servers

22. A PCI extension cable connects the server to the appliance, allowing you to “Wire Once” for all future 10 GbE & FC ports (provides a typical 4:1 cable consolidation and at least a 2:1 card reduction)
