Virtualizing servers, storage and even networks will change the face of IT and significantly impact the roles of storage professionals.
By Rich Friedman
Virtualization is dramatically changing how servers, storage and networks are configured and managed. But virtualization technologies aren't just changing storage environments; they're rapidly changing the nature and scope of storage jobs. Virtualization creates more interdependencies across different technology domains, which can instigate political turf wars over who should architect, divvy up and manage storage resources. Should it be the storage, network, server or VMware administrator?
"With server virtualization, storage administrators are, in some ways, ceding control of large blocks of storage to be allocated and managed by those responsible for VMware," said James Damoulakis, chief technology officer at GlassHouse Technologies Inc., Framingham, Mass.
FCoE could tip balance
Traditionally, Fibre Channel (FC)-based storage-area networks (SANs) have been, by and large, under the autonomous control of storage administrators. But Fibre Channel over Ethernet (FCoE) could disrupt that arrangement. As FCoE begins to take hold over the next two years to four years, even more questions about roles and responsibilities will arise. It's possible that the storage staff could be squeezed out, with network administrators finally taking control of the storage network.
"I'm betting that it will happen over time, but it will probably be a long time," GlassHouse's Damoulakis said. "With the continued use of Fibre Channel, even over Ethernet, the specialized knowledge relating to zoning and LUN [logical unit number] masking will probably be left either to the storage admin or to a liaison role that straddles both storage and networking."
Today, the storage administrator dictates the type of network supporting the storage environment, said Bob Laliberte, an analyst at Enterprise Strategy Group in Milford, Mass. However, "it's easy to imagine that changing," he added. "If FCoE takes off, will the deployment of Ethernet switches be controlled by storage or networking companies?" And who controls the budget -- the storage team or the networking group? The most likely scenario, he said, will be the elimination of siloed IT groups replaced by hybrid IT groups, on either a project or permanent basis, staffed by members with expertise in networking, storage, servers and virtualization.
