iSCSI: Learn it or be left behind

iSCSI: Learn it or be left behind Two tech trends will give iSCSI storage yet another boost, so it may be time to brush up on your IP skills. At the tail end of the Internet boom, I was working for a fly-by-night, storage-focused telecom company when I first heard about iSCSI. Given the growth of the Internet, a storage technology based on IP seemed a safe bet. Ethernet was becoming the global transport du jour, so iSCSI appeared to be a sure winner--networking leader Cisco Systems had gobbled up early iSCSI pioneer NuSpeed Internet Systems for $450 million in 2000. But like many technologies from that era, iSCSI didn't live up to its early promise. Back in 2000, the protocol was fairly new and marginally stable products were extremely basic. I remember seeing a NuSpeed/Cisco box at Interop. It had one port for connecting to a server and another for connecting to a storage system. In other words, it was a basic protocol converter and little else. At the time, vendors of 16-port Fibre Channel (FC) switches probably laughed off ...

  • Rein in NAS with file virtualization

    NAS filers have sprung up largely unchecked in many companies, creating major management headaches and forcing companies to reevaluate how they handle this critical piece of storage infrastructure. File virtualization appliances can address multiple filer pain points by pooling disparate storage, providing a global namespace and making short shrift of data migrations.

  • Per-protocol pricing gets murky

  • Terabyte drives arrive

  • Backup apps take small steps to improve encryption

  • Are you ready for new compliance rules?

    Two things to know about storage and regulator compliance: There's no single technology product that meets all compliance requirements and there's plenty of prep work to do before you even think about technology. The first step is to define your unique requirements, including compliance and litigation-readiness needs, as well as business productivity and service-level objectives.

  • Power costs put the squeeze on storage

    Storage shops keep growing and growing, adding capacity to keep up with the business. But the cost of powering all that additional capacity and keeping it cool is growing, too, and some data centers are being pushed to their limits. Thinking green can help stem the tide of soaring power costs and also help you figure in the cost of end-of-life disposal for your aging equipment.

  • Are backups a waste of time?

    by  James Damoulakis

    Data protection is now much more specialized due to increased user expectations and new technology options. We need to rethink the way we approach risk and risk-related services.

  • iSCSI: Learn it or be left behind

    by  Jon Oltsik

    Thought you might get by without considering iSCSI storage? Think again. With continuous progress on the iSCSI protocol and steadily improving products, the technology is now gaining enterprise stature. Savvy users should prepare themselves now for iSCSI.

  • We're in the midst of some seismic shifts in the storage world

    Storage Bin: Changes in the tech world can evolve subtly or may hinge on a big, revolutionary event. Either way, we're in the midst of some seismic shifts in the storage world, and both vendors and IT pros will have to adjust to a new world order.
