Access "SAN consolidation with director-class switches"

Published: 18 Oct 2012

A single director-class switch can replace multiple smaller switches while offering growth flexibility, high availability and a bevy of advanced features. The heart of any Fibre Channel storage-area network (FC SAN) is the switching equipment that connects the host servers with the storage systems. This switching equipment performs basic connectivity between FC devices and can also: Determine the type of FC devices that are connected Handle FC zoning functions Typically allow connections to other Fibre Channel switches to extend the storage network There are two basic classes of FC switching equipment: directors and switches. And while they both perform the same fundamental functions, there are significant differences between the two switch classes. Basic FC switches generally have a fixed number of ports and provide basic switching functions with limited scalability and redundancy within the switch. This type of FC switch is available today from Brocade Communications Systems Inc., Cisco Systems Inc. and QLogic Corp. At the high end of the switch spectrum ... Access >>>

    • Dedupe and compression cut storage down to size by W. Curtis Preston

      Data reduction technologies like data deduplication and compression have been well integrated into backup systems with impressive results. Now those benefits are available for primary storage data systems.

    • SRM tools struggle to meet today's demands

      At one time, storage resource management (SRM) applications tried to be all things for all storage shops, with little success. Modern data storage environments require new tools to navigate the intricacies of virtualized environments, but the jury's still out on whether storage management vendors can meet those needs.

    • SAN consolidation with director-class switches by Dennis Martin

      A single director-class switch can replace multiple smaller switches while offering growth flexibility, high availability and a bevy of advanced features.

    • Tape may be teetering, but it's still a big part of backup ops

      Tape no longer holds the place it once did in most firms' backup environments, but most storage shops still rely on it to some degree. Our Snapshot survey finds that while the vast majority of respondents use disk in backup, nearly 40% plan to buy tape gear this year.

    • Seeking clarity in the clouds

      After you wade through the confusion that vendors have created, you'll find there are advantages to both public and private cloud offerings.

    • The solid state of storage efficiency

      Storage managers want to use their storage systems more efficiently and vendors are finally forking over the tools to do it; but there may be a catch as vendors are faced with decreasing disk sales.

    • The modernization of backup: More disk, less tape by Lauren Whitehouse

      ESG's 2010 Data Protection Survey shows that the trend away from tape continues, with the economics of both deduplication, for disk-based backup, and cloud storage, for long-term retention, contributing to tape's decline.
