Are you taking the iSCSI plunge?

Unstoppable iSCSI iSCSI is not only here to stay, it's likely to take a leading role in many storage shops. We've watched iSCSI grow from a standard into a real technology that has spawned specific products, to the point where there are a large number of vendors providing iSCSI products. More importantly, we're seeing user adoption of iSCSI growing rapidly. The vast majority of iSCSI customers still have Fibre Channel (FC) in their SANs. However, iSCSI has gained a substantial foothold without necessarily displacing FC, and the iSCSI juggernaut appears to be unstoppable. There's a great deal of value in networking storage, but the majority of IT shops still use DAS to some extent. FC has failed to reach the ubiquity of other computer networking technologies largely because of its cost and complexity. The Enterprise Strategy Group (ESG) believes that IP-based networking, with iSCSI as a fundamental technology, has the potential to raise the level of adoption to reach the masses. We're just on the threshold of iSCSI becoming a ...

Features in this issue

  • 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.

  • Removable disk vies with tape

  • 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.
