Leading Analyst Firm Reports That Astute Networks' Flash VM Storage Appliance Eliminates Virtual Machine I/O Performance Barriers for Virtual Server and Virtual Desktop Environments

Astute Networks, Inc., the leading provider of performance storage for virtual machines, today announced that its ViSX G4 Flash VM storage appliance has been featured in the Taneja Group report, "Accelerating I/O-Intensive Virtualized Applications." The Taneja Group profile outlines the I/O performance constraints faced in most virtual environments and how ViSX accelerates virtualized application performance, increases VM density, and dramatically increases the number of VDI (Virtual Desktop Infrastructure) users.

"Key to the ready adoption of the Astute's ViSX VM storage appliances is that it drops seamlessly into an existing virtual infrastructure," said the Taneja Group analysts in the report. "ViSX is a non-disruptive, high-performance flash solution that avoids forklift upgrades, ripping and replacing, or otherwise re-architecting production environments. Astute has deliberately aimed at Networked Flash as the most cost-effective way to leverage flash technology because it puts the technology in the right place -- on the network -- to be most effectively shared by all VMs across all hosts while preserving current data protection and storage management practices. With a focus on tight hypervisor integration, purpose-built ViSX solves the virtual I/O performance constraint in a matter of minutes with almost no impact on the virtual server administrator."

The Taneja Group report explores the range of mixed results for flash "optimizations," including flash in the server, flash in the storage array, and flash in the network. The report concludes that the ideal solution to minimize virtual infrastructure disruption is "networked flash," the concept of enabling high-performance I/O for virtual environments by intelligently leveraging a shared flash appliance over common Ethernet iSCSI storage networks. ViSX employs a networked flash architecture to maximize the utilization and performance of flash as shared storage while completely optimizing both TCP and iSCSI traffic. The report explains that using this architecture, ViSX VM storage appliances offer the following advantages:

  • Shared high-performance storage with comprehensive data protection that enables virtualization of demanding I/O intensive applications
  • Maximizes flash ROI with an optimal design for both performance and efficiency
  • Deploys in minutes without disruption to server operations, existing capacity storage, or virtual server admin management processes

ViSX flash-based VM storage appliances are purpose-built to deliver unprecedented random IOPS performance and unprecedented IOPS per dollar value, helping to unleash the full potential of virtualized datacenters. The Networked Flash™ architecture of ViSX combines ultra-reliable eMLC Flash solid state storage modules with Astute's own custom designed high-performance, 10/1GbE DataPump Engine™ network protocol processor that completely offloads and dramatically accelerates network (TCP) & storage (iSCSI) protocol processing. Together, they eliminate all of the critical I/O bottlenecks that can affect virtualized applications. ViSX appliances also support integrated in-line de-duplication to significantly increase overall effective capacity. Unlike other traditional and flash storage systems, ViSX de-duplication technology has no impact on performance.

"Because of features like the custom DataPump Engine and high-performance de-dupe, many other flash solutions will be hard pressed to match the IOPS/$ of ViSX G4," concluded the Taneja Group report. "With benefits like increased total VM density, improved performance for all I/O constrained VMs [by removing contention for shared traditional storage], and the ability to deploy in minutes factored in, ViSX G4 has an obvious and immediate ROI justification."

"We set out day one to fully leverage our patented technology into a family of purpose-built appliances that eliminate known problems and pain points experienced by a majority of organizations that have virtualized their infrastructure. Be it added performance for virtualized servers and applications, or removing the performance and cost obstacles holding back wide deployment of VDI, we are pleased that the Taneja Group report acknowledges that ViSX has succeeded in its intended purpose," said Steve Topper, CEO of Astute Networks.
