  • Voice apps can strain storage

    Digital voice recordings are creeping up on storage like e-mail did a decade or so ago, but they're roughly 1,000 times larger per element. Here's how to prevent them from overwhelming your data center.

  • iSCSI moves up the ranks

  • New life for InfiniBand

    InfiniBand storage is finally emerging, but despite its cost, speed and scalability advantages over Fibre Channel, acceptance has been slow in enterprise data centers. But clustered, high-performance computing and demanding applications have helped renew interest in InfiniBand-based storage networks.

  • New DLT drive tops a terabyte

  • Finding Data

    Archiving applications are increasingly being used to minimize online data stores and to meet compliance requirements. Most of those archivers include search features, but the capabilities vary widely. Understanding how these search tools work will help you find the best fit for your company.
