Tony you are correct in your assesment...Host side of array runs at 8GB....BE runs at 4GB (could be 2GB depending on what dusks you have). you can check in the GUI to see what speed your emclosures are currently running at .  open out the physical  bit of the array. the enclosure speeds should be listed against the enclosures.  Or you can run the following navicli command - naviseccli -h backendbus -get -speeds   jim
We would like to migrate our CX3-20 SAN to CX4-120.  We prefer to opt for 8GB - prepare for the future need.  We just wonder whether we can keep the existing DAE (Running 300GB 15krpm FC Disk) or we have to replace it with new ones ?  Thanks
Is DAE for CX3-20 different from that for CX4?
