One thing holding back people here in Europe is lack of MetroCluster support. Once that is fixed I expect Europe to catch up with the cDOT adoption rate.
Speaking of MetroCluster, did anyone else notice the launch of Optical SAS? It allows the use of single-mode fibre for disks in stretch metros, although FCVI still needs to be over multimode. You also save from not having to use the 6500N FC-SAS bridges.
Other limitations on Optical SAS:
- If optical SAS cables are used for inter-shelf cables, optical SAS cables must also be used to connect to storage controller - Only one pair of patch panels can be used between connections - Only 6Gb/sec configurations are currently supported, no IOM3 support - No support for DS4486 in MetroCluster configuration - Limitation of 96 SSD spindles per stack - FAS22xx NOT supported
