Dataram Corporation [NASDAQ:DRAM], a worldwide leader in the manufacture of high-quality computer memory, storage products and software, today announced that its XcelaSAN ® storage optimization appliance dramatically reduces the total cost of computing in virtualized environments. Tests show that XcelaSAN paired with one entry-level midrange storage array exceeds the VMware ESX performance of three high-performance midrange storage systems for about one tenth the cost.

Using workload details from a VMware authored whitepaper entitled ‘ 100,000 I/O Operations Per Second, One ESX Host,’ Dataram demonstrates that XcelaSAN improves efficiency and performance for VMware users. Results show that XcelaSAN improves productivity by enabling more transactions at lower cost and with less infrastructure.

XcelaSAN delivers transparent, dynamic performance improvement to VMware customers experiencing I/O bottlenecks. Storage utilization improves in virtualized environments when XcelaSAN is installed since customers can use more of the available installed capacity without negatively affecting performance. Companies can now run more virtual machines per physical server to fully realize the potential of virtualization to reduce costs.

“XcelaSAN allows IT managers to easily and cost effectively accelerate application data in VMware environments without the need to install additional midrange storage or migrate to high-end storage,” said Eric Schwartz, Sr. Systems Engineer with Dataram. “In a virtualized infrastructure, XcelaSAN reduces the need to overprovision by providing more efficient resource utilization. The result is significant reduction of the total cost of computing.”

Companies that need to maximize the efficiency, performance, high availability and lifespan of their virtualized storage infrastructure will benefit from Dataram’s XcelaSAN storage optimization appliance.
