Learning Tree Deploys Xsigo Virtual I/O to Expedite Data Center Virtualization

Corporate Training Firm Deploys Virtual I/O to Reduce Cabling Complexity by 80%, and Accelerate I/O Management by 20X

SAN JOSE, CA--(Marketwire - September 27, 2010) -  Xsigo Systems, Inc., a technology leader in data center I/O virtualization, today announced that Learning Tree International, a world leader in hands-on training for managers and technology professionals, has deployed Xsigo's award-winning I/O virtualization technology to support data center virtualization efforts. By using Xsigo, Learning Tree reduced cabling complexity by 80% and accelerated I/O management tasks by 20X. As a result, the company was able to expand its server capacity instantly without added capital cost or IT headcount, and expects to save 50% on the capital cost of future server additions.

"Our goal is to virtualize 100% of our applications, and we recognized early on that I/O issues like performance, complexity, and cumbersome management would present barriers to meeting that goal," said Eric Smith, director of enterprise infrastructure services at Learning Tree. "With Xsigo virtual I/O we have eliminated I/O bottlenecks that constrained server performance, and we have streamlined management to let us complete tasks in minutes that would otherwise take days, putting us on track to meet our virtualization goal on time and at the lowest possible cost."

Headquartered in Reston, Virginia, Learning Tree offers hands-on training courses that have enhanced the professional skills of more than 2 million employees from more than 65,000 organizations. The company's virtualization infrastructure includes VMware ESX 4.0 software, Dell servers, NetApp storage, and Xsigo VP780 I/O Directors with 20Gb server connections. Xsigo offers a range of solutions that deliver from 10Gb to 40Gb of bandwidth through each server connection to eliminate I/O bottlenecks with performance up to 40X faster than typical 1Gb Ethernet connectivity. 

For Learning Tree, a key benefit of virtual I/O is flexible storage connectivity. Because Xsigo allows all virtualized servers to access all available storage types -- Fibre Channel, CIFS, and NFS -- it is now possible to run any application on any server, enabling flexibility that would have been cost prohibitive with traditional I/O. A second benefit is the ability to quickly re-configure LAN connectivity in software to meet new operational requirements. 

"We recently added a load balancer and needed to configure a new network for the virtual machines that would reside behind that device," Smith continued. "With traditional I/O it would have taken days to install and configure NICs on the hosts, and then add the needed cabling. With Xsigo we did it in minutes without touching the servers."

The Xsigo VP780 and VP560 I/O Directors consolidate data center infrastructure and provide dynamic connectivity from any server to any Ethernet or Fibre Channel network, a key requirement of cloud computing. At VMworld 2010, Xsigo announced a significant advancement in virtual I/O technology, an Ethernet-based version of its award-winning Xsigo I/O Director, the industry's first virtual I/O technology to leverage the standard Ethernet ports found on every x86 server. With Xsigo, data center managers can reduce cabling requirements by 70 percent, cut power consumption by 30 percent, and complete routine management tasks in seconds rather than hours or days.

"As our environment grows, we can now add servers in under an hour -- we just connect two cables and use pre-defined templates to configure the I/O," Smith concluded. "Before this, we had to install, configure, and connect up to eight NICs and perhaps two Fibre Channel HBAs, which required days of repetitive configuration work that took time away from higher value tasks." 

"We are delighted that Learning Tree made Xsigo a part of their initiative to achieve a fully-virtualized data center," said Bruce Fingles, vice-president of product management and alliances at Xsigo. "They are on the cutting edge of a wave of mid-sized firms who want to do more with virtualization and who recognize that the performance, agility, and simplicity of virtual I/O can help them get there faster and at less cost."
