New Fibre Channel standard runs over Ethernet

A new Fibre Channel (FC) standard is in the works that leverages the venerable Ethernet architecture. Products based on the standard could appear in a few years, but it's unclear whether storage managers, particularly those who are happy with their FC environments, will be interested. Last April, a collection of IT vendors (including Brocade, Cisco, EMC, Emulex, IBM, Intel, Nuova Systems, QLogic and Sun Microsystems) proposed the new Fibre Channel over Ethernet (FCoE) standard to the T11 Committee of the American National Standards Institute, which would allow SAN I/O traffic to be transported over Ethernet networks. Unlike protocols like FCIP, which encapsulates FC and sends it over a TCP socket, FCoE would map directly onto Ethernet. According to Greg Schulz, senior analyst and founder of StorageIO Group, Stillwater, MN, a key benefit of FCoE is that it could potentially "remove the overhead of TCP/IP from the equation," leveraging the underlying Ethernet-based network while supporting FC frames and upper-level protocols.

  • Fibre Channel director face-off: Brocade vs. Cisco

    by  Jerome Wendt

    Fibre Channel directors are the choice for consolidating isolated SAN fabrics. Brocade's 48000 Director and Cisco's MDS 9513 Multilayer Director are the undisputed leaders in this small field, but they offer very different paths to storage services and consolidation options. We'll help you decide which company's product is the best director for your storage environment.

    Most companies don't have a detailed policy that governs what data they need to keep and what data should be destroyed. Deciding on the destruction levels you're comfortable with is the easiest part of this puzzle. The most complicated piece is figuring out what to destroy and when, and then sticking to it.

  • How to write an archiving program RFP

    by  Sharon Fisher

    With so many archiving systems on the market, putting together a request for proposal (RFP) for an archiving program for structured, semistructured or unstructured data is a key step. It's equally important that your team is well-prepared to evaluate vendor proposals so you'll end up with a product that fits your company's needs at a price that doesn't break your budget.

  • Demystifying Unix dump
