VirtenSys Tackles VM Bottlenecks

Startup produces combined, high speed I/O switches for virtual machine hosts.

VirtenSys has announced the general availability of the VirtenSys I/O 4000 Series for use as virtual I/O switches capable of removing a virtual environment bottleneck and increasing the number of virtual machines resident on a single server.

The VirtenSys 4000 switches are capable of handling both high speed networking and storage traffic, which means fewer network interface cards and host bus adapters are needed to handle all the traffic generated on a server hosting multiple virtual machines.

The switches can be virtualized to handle Ethernet network traffic, SAS/SATA or Fibre Channel storage traffic, or Fibre Channel over Ethernet, which deals with both.

By virtualizing I/O, more virtual machines may run on each host server. Pay Pal is an early VirtenSys I/O 4000 adopter, according to Kevin Cantoni, VP of Pay Pal product development, who is cited in the announcement. "I/O virtualization is an important part of our green strategy," he said.

"The VIrtenSys approach to I/O virtualization complements VMware vSphere," said Shekar Ayyar, VP of infrastructure alliances at VMware, in the announcement. Having virtualized I/O introduces greater flexibility with less overhead to data center operations, he added.

Cisco Systems entered the blade server market in part based on its strength in offloading network and storage traffic from servers running a concentration of virtual machines.

The VirtenSys switches support Intel 10 GE network interface cards, Neterion 10GE cards, QLogic Fibre Channel host bus adapters and LSI SAS/SATA MegaRAID controllers. The company raised $16 million in venture capital funding earlier this month.

VirtenSys was founded in 2005, and is based in Beaverton, Ore., and Manchester, UK.
