Removable disk vies with tape

The battle between disk and tape has heated up for small- to medium-sized businesses (SMBs), with several vendors launching entry-level removable disk products designed to replace tape as offsite backup media. Tandberg Data's RDX QuikStor has been available since October, while Dell launched its PowerVault RD1000 in November. Last month, Imation announced its RDX series of removable hard-disk systems along with a separate removable disk solution--Imation's Odyssey solution, a bundle that includes a docking station, hard-disk cartridge and a full version of EMC's Retrospect software at a starting price of $249. Imation introduced its Ulysses drive--a removable disk drive encased in an LTO Ultrium form factor that can slip unobtrusively into a tape library--in the first quarter of last year. The Tandberg Data and Dell and Imation RDX products are based on ProStor Systems' RDX removable disk technology, and offer native disk capacities of 40GB, 80GB and 120GB; Imation also offers a 160GB RDX native capacity disk.

  • Integrating iSCSI and FC storage

    Mixing iSCSI with Fibre Channel (FC) allows you to make more efficient use of installed storage capacity, but marrying the two protocols isn't without its challenges. Bringing iSCSI into existing FC SANs raises integration issues and leads to a somewhat more complex storage infrastructure that requires IP and FC knowledge, as well as the ability to manage and troubleshoot a multiprotocol storage environment.

  • Clustering ERP apps

    For mission-critical apps, availability is the key. Clustering those applications can ensure they stay up and running, but clustering often conjures up images of complex technologies and an environment that's fragile and complex. Still, for most companies, the benefits of clustering are profound enough to mitigate its risks.

  • Protect laptop data

    When your company's data is mobile, it's far more vulnerable, so protecting laptop data is critical. Protecting data on laptops is a two-pronged process: ensuring the data is always available using backup, and securing data from prying eyes through encryption.

  • Are you taking the iSCSI plunge?

    iSCSI has grown from a theoretical standard into a real technology with real storage products. Although once considered by many to be a Fibre Channel killer, iSCSI has gained a substantial foothold without necessarily displacing Fibre Channel. Companies of all sizes are taking the plunge, and the iSCSI juggernaut appears to be unstoppable.

    Everyone thinks about online data in the same way: You write it, read it, rewrite it and keep it forever. But many organizations have far more data that's written once, read a few times and kept alive forever. You might say this bulk data is "write once, read several times" (WORST), and it can bloat your storage environment.
