FCoE uses Ethernet as it’s physical transport



Roadmap to 100GFCoE!

Inter-Switch Links (ISL) provide higher core bandwidth than its sister edge speed



Roadmap to 160GFC ISL!


FC Edge

These speeds can also be used for ISLs

Edge Links are the predominate SAN inter-connect

hdd support
HDD Support
  • Low RPM (below 10,000) drives, often with a SATA drive interface
    • Best value for cheap and deep solutions, $/GB is key purchase criteria
    • LFF 3.5" HDDs satisfies this better than SFF 2.5“ HDDs
  • High RPM (10,000 and above) drives, often with a SAS drive interface
    • Best value for performance driven solutions, $/IOP is a key purchase criteria
    • Two 10k 2.5” drives can outperform a single 3.5” drive spinning at 15k RPM
  • Solid State Drives (SSD)
    • SSD delivers the best performance, but at a premium price
    • LFF 3.5" HDDs satisfies this better than SFF 2.5“ HDDs

dc power markets
DC Power markets
  • Telecommunications, Disaster recovery
    • With a need for failure proof” systems, the markets have been long time users of 48v DC powered equipment for its ability to run on backup power and AC to DC conversion at power in.
  • Military and transportation markets
    • As data storage needs move from building-based data centers to vehicles, trains, and other mobile installations, DC power is a logical choice with existing DC power storage and recharge capabilities unmatched by AC power. This also applies to the growing “data center in a cargo box” market, allowing for quick deployment of IT resources in remote areas.
  • “Green Initiatives”
    • We all know that computer components operate inside the box with DC voltages, and that AC-to-DC conversion wastes power and generates heat. IT facilities are evaluating the ability to convert to more efficient DC power for entire data centers, lowering the IT center operating costs and improving backup power options.
