FCoE vs. iSCSI vs. iSER

One of the features of modern data centers is the ubiquitous use of Ethernet. Although many data centers run multiple separate networks (Ethernet and Fibre Channel (FC)), these parallel infrastructures require separate switches, network adapters, management utilities and staff, which may not be cost effective. Multiple options for Ethernet-based SANs enable network convergence, including FCoE (Fibre Channel over Ethernet) which allows FC protocols over Ethernet and Internet Small Computer System Interface (iSCSI) for transport of SCSI commands over TCP/IP-Ethernet networks. There are also new Ethernet technologies that reduce the amount of CPU overhead in transferring data from server to client by using Remote Direct Memory Access (RDMA), which is leveraged by iSER (iSCSI Extensions for RDMA) to avoid unnecessary data copying. That leads to several questions about FCoE, iSCSI and iSER covered in this presentation: If we can run various network storage protocols over Ethernet, what differentiates them? What are the advantages and disadvantages of FCoE, iSCSI and iSER? How are they structured? What software and hardware do they require? How are they implemented, configured and managed? Do they perform differently? What do you need to do to take advantage of them in the data center? What are the best use cases for each?
