IBM touts SSD data management software for its servers, arrays

21.05.2009
IBM is now providing management software across all of its servers and storage arrays that identifies the most highly accessed data applications and migrates them to solid-state disk (SSD) drives to improve application performance.

The company also announced today that it is offering SSDs in its Power6 iSeries server line. IBM already offers SSDs from STEC Inc. as an option in its x-Series blade server line and DS8000 enterprise-class storage arrays.

Clod Barrera, chief technical strategist for IBM Systems Storage, said that by using SSDs to store highly accessed data, such as that which resides in relational databases, application performance can be improved eight-fold. "We asked ourselves, isn't there a sweet spot or a place where we can move the indices plus hot tables for better performance, and the answer is yes," Barrera said. "By moving only a fraction of the data, response time was [eight times] better than the hard disk drive-only base line."

Based on IBM's testing, the new SSD offerings, combined with the Smart Data Placement tools, can reduce the physical footprint of the storage needed by about 80% and energy consumption by up to 90%. That's because SSDs use less power, and less frequently used data can be moved off primary servers and storage.

For example, a bank running a DS8000 storage array in support of DB2 for zOS and SAP, can improve business performance by more than 30% and reduce the physical storage footprint by 60%. That would reduce the bank's energy consumption by more than 70%, IBM state in a statement.

IBM said its Smart Data Placement software includes nine tools that will work with the SSDs now available on all of its hardware, from servers to storage arrays. The software comes in different variations, some of them new, some that are upgrades to existing offerings.
