Access "Speed wars: Fibre Channel vs. Ethernet"
This article is part of the Vol. 4 No. 12 February 2006 issue of Storage Products of the Year 2005
The appeal of 10Gb/sec Ethernet over copper is evident, but can it displace Fibre Channel in the data center? BRACE YOURSELF FOR ANOTHER ROUND OF THE PERPETUAL storage networking competition of whose pipe is the fastest. Just as Fibre Channel (FC) pulls significantly ahead in the performance race with 4Gb/sec speed, IP/Ethernet is about to leapfrog FC with 10Gb/sec Ethernet over copper wire. And no sooner will data centers have absorbed 4Gb/sec FC than 8Gb/sec will arrive. Do data center storage managers care about faster pipes? Judging from the current demand for high-speed storage networking links, perhaps not. In a survey conducted last June by the Milford, MA-based Enterprise Strategy Group (ESG), 50% of respondents reported using 1Gb/sec FC. "At that time, 2Gb/sec FC was just beginning to be widely deployed and 4Gb/sec FC was about to start up," says Tony Asaro, senior analyst at ESG. Based on that survey, "the market isn't demanding 8Gb/sec or 10Gb/sec," he concludes. "It's not yet even demanding 4Gb/sec FC." But analysts see two uses for the greater ... Access >>>

Speed wars: Fibre Channel vs. Ethernet
Just as 4Gb/sec Fibre Channel is poised to make its move into the data center, Ethernet is roaring back with its 10Gb/sec technology. But the lure of pure speed might not be enough for Ethernet to overtake Fibre Channel--at least for now.
Shopping for storage: One vendor or more?
Buying storage today is more difficult than ever. You need to get the best acquisition price, the lowest long-term TCO and avoid vendor lock-in. On top of it all, you must decide which is best: one vendor or more?

Not just a big switch
Fibre Channel directors don't just provide lots of ports, they also offer ways to connect disparate SANs, isolate data and devices within a fabric, and configure throughput for specific applications. We look at how the big three directors match up.

Marriott's lost tapes are just the latest in a string of high-profile storage snafus
Storage bin: Marriott's lost tapes are just the latest in a string of high-profile storage snafus. But with plenty of viable security solutions available, there's simply no excuse for these very public blunders.

The midrange array market may still be hot, but storage managers are wary of getting burned. While midrange vendors keep piling on the features, storage pros are becoming disenchanted with midrange systems despite their more modest price tags.
