iSCSI Performance - Celerra vs Clariion

Question

I have a customer asking which he'll see better performance from, iSCSI through the NS or through the CX. Is there a definitive answer on the subject? Maybe a whitepaper? I Like to think that using etherchannel across all four nics and being able to address both SPs would offset any performance lost by going through the datamovers, but what do I know.  Any assistance on the subject would be appreciated. Thank you.

I dont think you will find a performance comparison like that

right know Celerra ISCSI has some features in the networking side and more snapshots than Clariion but over time the EMC direction is to focus on Clariion ISCSI

If you need to choose right now I wouldnt base it on performance but on the requirements and what snapshot and replication technology you want to use

Obviously customers using more Fibre-Channel would choose Clariion ISCSI for familiarity with NaviSphere and MirrorView

whereas customers mostly using NAS would choose Celerra ISCSI because they are more familiar with the file system and Celerra Replicator concepts

Thanks, I appreciate the quick response. This customer is going to be all FC-connected except for this one office that houses the Celerra, so that makes the choice easy (iSCSI on Clariion to keep familiarity across interfaces).

Cheers
