INFORTREND NEW TECHNOLOGY - "DYNAMIC LD ASSIGNMENT" - PROVIDES UNPARALLELED LEVELS OF PERFORMANCE AND AVAILABILITY
"Dynamic LD Assignment" Helps to Maintain High Performance of EonStor RAID Subsystems Even When Data Links Fail

SAN JOSE, Calif., Dec. 2, 2008 – Networked storage expert Infortrend® (Public TPE: 2495) today announced a new technology "Dynamic LD (logical drive) Assignment" which brings up to a 55% boost in write and up to a 10% boost in read performance for its EonStor® dual-controller RAID subsystems during data path failure. With the introduction of "Dynamic LD Assignment", Infortrend has proved its commitment to continually advance the limit of best-in-class performance, whilst at the same time providing high availability of systems.

A failed data link can often result in the breakdown or degradation of system performance. In a business-critical deployment where a system is expected to run 24/7 and at optimal performance, even one second of performance degradation is intolerable since it may lead to major business losses. To alleviate this problem, Infortrend has developed "Dynamic LD Assignment"; technology that provides high availability on EonStor subsystems. This new technology minimizes the potential impact the failure of the data path could have on overall performance levels. When a data path is broken, clients who adopt dual-controller EonStor arrays can rest assured of not only the highest availability but the best possible performance.

Typically, failed data links lead to performance degradation because the storage controller has to re-direct the I/Os targeting the logical drive whose primary data path is broken. Infortrend now supplies all its EonStor dual-controller arrays with the "Dynamic LD Assignment" technology to improve performance by eliminating the re-rerouting overhead. Once the failure is identified and corrected, optimal system performance can be immediately restored.

"In today’s intensive IT environments that require non-stop operation, ensuring system availability and uptime are among the top priorities for business continuity," said Thomas Kao, product planning director at Infortrend Inc. "However, to such a company as Infortrend which takes delivering high-performance storage solutions as one of its development commitments, maintaining peak performance levels is no less important than system availability. Our uncompromising demand for performance drives us to develop "Dynamic LD Assignment." For clients utilizing our dual-controller arrays, we can now provide a solution that alleviates the performance degradation issue caused by a data link failure."

Availability

The "Dynamic LD Assignment" now comes with all EonStor Fibre-, SAS-, and iSCSI-host redundant-controller models using Firmware ver.3.64J or later.
