Dedupe and virtualization don't solve the real problem: Editorial

Dedupe and virtualization don't solve the real problem I guess I didn't need confirmation, but our recent Storage Decisions conference in Toronto clarified what's on storage managers' minds these days. Sessions on data deduplication and configuring storage for virtualized server environments were packed, and the majority of conversations centered on these two technologies and practices. But there were also plenty of questions. It's no surprise that these two topics are top of mind these days. The server virtualization juggernaut isn't slowing at all--and it's likely to pick up steam with new or improved players like Virtual Iron Software and Microsoft challenging VMware's dominance. And storage vendors are hardly sitting on their hands. They're focusing on virtual server interoperation and integration with alliances such as Symantec's recently announced Veritas Virtual Infrastructure (VxVI); the coordinated venture with Citrix Systems bundles XenServer with Veritas Storage Foundation to create an integrated management package. ...

  • Solid State: New frontier for storage

    Solid-state media is starting to show up as an option for traditional storage arrays because it offers higher performance and lower power consumption. However, there are still reliability concerns related to wear out, the slower write performance of flash cells, and issues related to array management and interoperability.

  • DLT-S4 tape drives at bargain prices

  • Here comes 8Gig Fibre Channel

    New 8Gb/sec host bus adapters (HBAs) and switch devices have started arriving. But with storage arrays incorporating the new, higher speed technology still months away, end-to-end 8Gb storage infrastructures are still in the planning stages. Storage managers can get a jump on their 8Gig configurations by upgrading switches and HBAs now, or by considering networking gear that supports Fibre Channel over Ethernet.

    by  Ellen O'Brien

    Many IT shops are moving from traditional rack-mounted servers to blade configurations in hopes of reducing power and floor space requirements in their data centers. But combining blade architectures with server virtualization can cause problems with I/O and storage systems.
