Dual-protocol arrays appeal to users

SAN users once forced to choose between iSCSI and Fibre Channel (FC) no longer have to make that tough decision. As consolidation and server virtualization drive iSCSI adoption, the newer protocol is making its way into storage environments as a complement to the proven FC protocol. Users can have the best of both worlds, pairing iSCSI and FC in one dual-protocol SAN array. Jim Poteet, director of technology at Overland Park, KS-based StoreFinancial Services, wanted both protocols when his company implemented an EMC dual FC and iSCSI array. Phil Treide, EMC's manager of Clariion marketing, notes that EMC now ships more than 50% of its Clariions as dual protocol with iSCSI. StoreFinancial, a provider of multimerchant gift cards, must meet a seven-second industry-standard response time when connecting to card networks for authorizations. "We wanted to have fibre to make sure we would respond appropriately to our card networks," says Poteet. "And we wanted to have iSCSI so that we can actually tie in other servers." Poteet's main ...

  • Survey: Fibre Channel rules planned purchases

  • Automate application recovery

    Today's application continuity computing (ACC) products are best suited for small- and medium-sized businesses, and are focused exclusively on Exchange, which most companies now consider a business-critical application. But the concentration on Exchange will likely change over the next few years, as several ACC vendors plan support for SQL Server and SharePoint in the future.

  • Best Practices: High hopes for thin provisioning

    Thin provisioning is a promising way to address allocation and performance. One of the biggest challenges when using the technology is knowing where your data lives, and whether it can be tracked or recovered if there's a catastrophic component failure.

  • Storage Bin 2.0: Winds of change push storage into a new era

    The transactional computing era is over. The Internet computing era is dragging data into the "cloud," and this new era will rain more files--and bigger files--down on you than you can ever imagine.
