LeftHand Networks Virtual SAN Appliance for VMware ESX Server enables customers to fully realise the benefits of infrastructure virtualisation across data centres and remote and branch offices

Bloxham, Oxfordshire, UK – 10th September 2007- LeftHand Networks® today unveiled the LeftHand Networks Virtual SAN Appliance (VSA) for VMware ESX Server. The VSA clusters the internal storage within multiple x86 server hosts running VMware ESX Server to create a full-featured SAN enabling advanced high-availability of data and applications in VMware Infrastructure environments. The powerful, yet cost-effective solution provides a completely fault-tolerant SAN without requiring the purchase of additional hardware, additional costs for power and cooling or additional footprint within the data centre.

Customers are realising tremendous benefits from server virtualisation. But with more applications running on a physical server, more applications fail if that server fails. As a result, customers require highly available virtual infrastructure for their applications, which in turn requires shared storage. In many cases, this is not an option due to the cost of physical shared storage. Even so, when shared storage is an option, the storage local to the server is not fully used. The VSA provides a cost effective shared storage solution via a redundant SAN with automated failover. The combination of the VSA and VMware Infrastructure provides an automated, high-availability solution for both application servers and storage with failover and fail back between physical machines.

The VSA empowers businesses to realise further the benefits of server and desktop consolidation, centralised management and backup, and disaster recovery solutions across the data centre as well as remote and branch offices. By implementing the VSA, businesses can reduce data storage costs and management fees while increasing storage use and improving data availability within a VMware Infrastructure environment.

"LeftHand Networks' open iSCSI SAN approach, which integrates SAN/iQ with enterprise-class x86 servers, makes the addition of a Virtual SAN Appliance a natural step forward," said John Humphreys, program director for IDC. "The Virtual SAN Appliance concept is truly unique in the VMware Virtual Appliance Marketplace and is indicative of the continued innovation in the server virtualisation marketplace."

The LeftHand Networks Virtual SAN Appliance enables the full possibilities of VMware Infrastructure in areas of the organisation where it was previously not considered. With the VSA, customers can deploy a highly available virtualised environment in a remote/branch office for less than 50 percent of the cost for a physical SAN. LeftHand is the first SAN vendor to deliver a product that virtualises and optimises internal storage disks within a server and across servers to create a Virtual SAN. The LeftHand Networks Virtual SAN Appliance for VMware ESX Server works within a VMware ESX Server host alongside other virtual machines/applications to optimise the virtualised infrastructure. The virtual SAN is a full-featured SAN that can be used to provide storage to both virtual and non-virtual applications, without the additional hardware costs associated with a traditional SAN.

"Virtual SANs represent a natural progression for virtualised environments. With a virtual SAN appliance, customers can deploy a SAN in their environment, enabling them to take advantage of the high availability capabilities of VMware Infrastructure," said Parag Patel, Vice President, Alliances at VMware.

The LeftHand Networks Virtual Storage Appliance for VMware ESX Server is the latest offering in the open iSCSI SAN family of products from LeftHand Networks and complements the company's physical SAN offerings. LeftHand's patented software platform, SAN/iQ, will run within a VMware virtual machine and carry the same capabilities and features made available in the physical storage systems built on LeftHand Networks, HP ProLiant DL320s and IBM x3650 servers.

"LeftHand Networks' flexible, open iSCSI SAN approach provides choice to our customers and is very attractive from a partner perspective," said Mike Duhaime, Direct Systems Support. "The addition of the LeftHand Networks Virtual SAN Appliance for VMware ESX expands our offering beyond physical IBM x3650-based SANs to virtualise disks drives within IBM Blade Centres and servers within remote office location to deliver a complete VMware® Infrastructure 3 and LeftHand SAN infrastructure."

Powered by SAN/iQ, the Virtual SAN Appliance allows customers to take advantage of a wide range of enterprise-class features, such as snapshots, thin provisioning, synchronous and asynchronous replication, automatic failover and fail back, and management through a single pane of glass.
