Voltaire and DataDirect Networks Deliver Native InfiniBand Storage to Customers Worldwide

Voltaire Ltd. (NASDAQ: VOLT), a leading provider of grid backbone solutions for data centers, today announced that it is working with DataDirect Networks, Inc., the data infrastructure provider for the most extreme, content-intensive environments in the world, to deliver native InfiniBand storage to customers worldwide. The companies recently completed cross-certification testing of Voltaire Grid Director™ InfiniBand-based switches and software with DataDirect Networks S2A9900 StorageScalerTM systems. Used together, the products deliver up to a 200 percent improvement in storage performance compared to solutions that use Fibre Channel.

According to leading industry analyst firm The Taneja Group, the growth of the native InfiniBand storage market may be similar to the fastest growing storage systems with a potential CAGR of 60-70 percent.(1)

“With the growth of scale-out, cluster computing architectures, we’re seeing increased demand for high-performance storage access,” said Dave Fellinger, chief technology officer, DataDirect Networks. “We specifically designed the S2A9900 to further enable InfiniBand clusters, which our customers are increasingly choosing as a highly scalable and stable interface technology. InfiniBand enables remote direct memory access data distribution, allowing the realization of a true ‘zero memory copy’ storage interface and a very efficient protocol. Voltaire’s InfiniBand switches are a great way for our users to gain exponential performance improvements at competitive prices.”

The S2A9900 StorageScaler™ platform provides extreme performance and capacity, with the ability to manage 1.2PB of capacity, in only two floor tiles, and deliver sustained throughput of up to 6GB/s for both writes and reads, per appliance. It is the first storage system to support native 20Gbps InfiniBand DDR host connections, enabling users to achieve their bandwidth goals using significantly fewer network connections.

Voltaire Grid Director™ switches provide high-performance 20 Gbps InfiniBand connectivity and microsecond latencies to enable high-performance applications to run on distributed server, network and storage resources.

“Businesses in industries including digital media, oil and gas, and life sciences that rely on high performance storage to run their applications will gain big benefits from native InfiniBand storage,” said Asaf Somekh, vice president of strategic alliances, Voltaire. “We’re pleased to work with our partner DataDirect Networks to bring these much-needed solutions to market.”
