Voice apps can strain storage

As companies implement digital voice applications, storage managers need to prepare for these new data sources. Voice over Internet Protocol (VOIP) phone calling is accelerating the evolution from an analog to a digital world and bringing new storage challenges to the data center. Before the digitization of voice, analog voice traffic was recorded on tape and perhaps later transferred to CDs or DVDs. Some of these recordings might have been listened to--typically 30 to 90 days after their creation--and then the media was archived or jettisoned. Some shops kept their voice-recording media for a longer period of time, but as the number of CDs grew, storage management problems multiplied. It's much easier today to store digital voice recordings as a file or row item in a large relational database; all of the tools and processes of modern data centers can be used to store, index, search, archive and expire this digital data. With so many different options to store voice that's been captured in a digital format, storage managers need...

Features in this issue

  • Fine-tune storage networks

    How key SAN components, principally host bus adapters and switches, are configured will determine overall SAN performance. If you know what to look for and how to make adjustments, performance issues can be greatly reduced.

  • 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.

  • The winners of Storage magazine's Products of the Year were surprising

    Storage Bin: The winners of Storage magazine's Products of the Year were surprising, as so few of them were big-name storage vendors. Here's Steve Duplessie's take on the subject.

  • Deploying Intelligent Information Management applications

    By deploying Intelligent Information Management applications, organizations can improve resource management by eliminating the storage of duplicate data, reduce risk by quickly responding to discovery requests, comply with record-retention and privacy regulations, and restore the right data faster.

  • Misplaced priorities

    by  Stephen Foskett

    In this age of compliance and despite well-publicized cases of data theft, a recent security survey from GlassHouse Technologies indicates that few companies are paying much attention to storage security.
