And I’ll give you a hint. EMC Engineering is not going to be the driving force, EMC Marketing will be. Their favourite words are “First to market with….” (fill in the blank)]]>
Is this a chicken and egg problem? I imagine if drives had 8Gb FC interfaces array vendors would wind up supporting it at least in a portion of their array and vice-versa.]]>
1. Most users don’t even utilize the 1Gbit they had originally. Going to 2BGit and then 4Gbit is pure marketing. The “Bigger-better-faster-more” crowd loves it.
2. Cached disk arrays that spread the IO load across the back end means that even if the switch-to-array speed is 8G, the distributed IO won’t even approach the 4G point.
3. Drive transfer rates don’t even come remotely close to the 8G limit, so when writing to a disk you’re still at the mercy of the physical limitations of the drive. The only exception to this *MIGHT* be in the case of Tier-0 or SSD disks, where the Solid State nature of the drive enables massive ultra-fast transfers.]]>
