looks at Ethernet block access storage protocols, with the candidates being AoE (ATA over Ethernet), FCoE (Fibre Channel over Ethernet) and iSCSI. As well as consultant Chris Evans, there are three Reg reader experts here: Geoff Barnett, Evan Unrue and "Mike1", all asked to contribute because of the high calibre of their …
ah come on...
There's only one way to find out..... FIGHT !!!!!
What about SRP?
SRP is SCSI Remote Direct Memory Access Protocol. Runs over Infiniband. Low latency. 40Gb pipes to the storage server (via the IB switch) - as oppose the 10Gb of Ethernet.
This is used by a number of companies and offered as a storage solution by a number of vendors (i.e. Infiniband based storage servers -e.g. Oracle's Exadata, Rorke's Galaxy server, etc).
Performance and scalability wise... I fail to see Ethernet as a SAN protocol layer being able to compete with Infiniband.
