Storage consolidation pays off for Michigan

IT department improves efficiency by turing three large arrays into one smaller array

Michigan's Department of Technology, Management and Budget (DTMB) has completed the consolidation of three large storage arrays into one smaller array at the Traverse Bay Hosting Center, which provides about a third of the state’s 4.4 petabytes of storage, according to a DTMB announcement.

The six-month project, which involved migrating more that 200 servers and consolidating 280 Firbe Channel ports, has generated $567,829 in refunds from storage vendor EMC in unused maintenance for fiscal 2010, DTMB said. The department expects that another $1.2 million in costs will be avoided through 2011.

The consolidation cleared floor space for other use at the Traverse Bay center, one of three storage facilities run by the department, and cut the bill for heating, cooling and power consumption in half.

Three years ago, DTMB, then known as the state’s Department of Information Technology, completed a data center consolidation project that closed 29 centers around the state.

The storage consolidation "marks a major next step in our consolidation story," Ken Theis, DTMB’s director and Michigan’s CIO, said in the announcement. "In 2007, we consolidated all of our data centers across the state down to just three secured centers, and now we are doing the work within those three centers to make them even more efficient."
