XtremIO, which is bringing unprecedented levels of performance, scalability, reliability, and ease-of-use to SAN storage with its breakthrough scale-out enterprise flash storage array, today announced it has closed an extended Series B funding round including Lightspeed Venture Partners and now totaling more than $19 million. David Gussarsky of Lightspeed will take a seat on the company's board of directors. The company, which has raised over $25 million since its founding in 2009, plans to devote the new capital to expanding its business operations and engineering team as the market demand for flash-based storage arrays accelerates.

"It is clear that hard drive based storage arrays have become the performance bottleneck in the data center infrastructure stack. Whether virtualizing servers or desktops (VDI), running analytics, or consolidating databases, a new approach is needed to bring storage performance in-line with the advancements made over the past several years in servers and networking," said Ehud Rokach, CEO of XtremIO. "XtremIO's array architecture was developed from the ground up to leverage the speed and unique abilities of flash memory, and with our strong venture backing we are ready to bring a tremendous leap forward in I/O and latency performance to the market, unveil unique new capabilities that hard drive based storage cannot match, and eliminate the complexity that has traditionally plagued SAN storage configuration and tuning."

"We are on the cusp of a massive technology shift from performance disk to flash technology for I/O intensive data center applications. After evaluating the market and XtremIO's technology, we are convinced that they have a breakthrough architecture and product to address data center storage I/O challenges," said David Gussarsky, Managing Partner at Lightspeed Venture Partners. "Lightspeed invests heavily in infrastructure companies with the potential to disrupt markets and with very strong technical and management teams. We are pleased to invest in and support XtremIO."
