10GBase-T power issues may slow 10GbE adoption

Ethernet adapters were announced in late January to support the 10 Gigabit Ethernet (GbE) over twisted pair (10GBase-T) standard ratified last summer. But it will be a year or two before products arrive to support them, say vendors and analysts, in part due to the power challenges posed by the new standard. 10GbE products have been available for some time, but 10GbE over CX4 co-axial cable can extend only to 15 meters and optical fiber options remain expensive. 10GBase-T over Category 6 or 7 twisted pair cabling can extend up to 100 meters, but power requirements hinder its cost-effectiveness. Ethernet adapter vendor Chelsio Communications announced two single-port, dual-speed 10GbE cards, the S310e-BT storage adapter and the N310e-BT server adapter, in mid-January. At the same time, Tehuti Networks announced its TN7588-S single-port adapter and TN7588-D dual-port adapter. The products support 10GBase-T, but consume more power than the 1GbE cards currently available. "Those are first-generation products [from Chelsio and Tehuti]...

Features in this issue

  • 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.
