PROVO, UT, March 10, 2010 – SirsiDynix®, the world leader in library technology, announces support for SirsiDynix Symphony® 3.3.1 when installed on VMware® virtual servers ESX 4.0 and ESXi 4.0. The announcement follows the company’s December announcement regarding support for Horizon™ when installed in a virtual environment.

“We told our customers that as they found opportunities to do more with less, we would find ways to support them. Virtualization is an effective way for libraries to maximize IT resources, so we are responding,” said Talin Bingham, chief technology officer for SirsiDynix. “While economic conditions may drive more libraries towards virtual environments today, as cloud computing becomes the standard, more libraries will benefit from virtualization in the future. We are ready now.”

Benchmark test results have been published to aid library customers in system optimization. Tests compared Symphony performance in virtual and non‐virtual environments using ISAM, MS SQL 2008 and Oracle databases.

In addition to supporting Horizon and Symphony in virtualized instances, SirsiDynix has an unparalleled Software‐as‐a‐ Service offering, completely alleviating hardware maintenance and scalability concerns. Over 600 customers employ SirsiDynix SaaS solutions in five datacenters around the world.
