IBM Inks Storage Software Virtualization Deal With Cisco: Page 5 of 5

Advanced Systems Group has already closed several deals using the TagmaStore array from Hitachi Data System, said Teter. With TagmaStore, several petabytes of heterogeneous storage systems can be attached to the back-end and managed as a single pool of storage.

The solution provider is now testing IBM's SAN Volume Controller in its lab, and it seems to be working well so far, said Teter. "We can connect to various hosts and various drive technologies, and implement policies (using SVC)," he said. "We are just starting to see the light at the end of the tunnel."

While TagmaStore offers high-performance features such as a quarter-Tbyte cache and HDS's crossbar switch backplane, IBM's SVC is lower cost, enabling it to be used in more midrange and enterprise environments, Teter said.

For heterogeneous storage networks, virtualization is a great solution, said Teter. "Before, virtualization was a solution looking for a problem," he said. "Now customers have issues with disparate storage, low utilization, file sharing, and policy controls. Virtualization is a great product to provide a turnkey solution for better management of storage assets."
