Flex System environment storage performance will be critical so expectations of the selected
storage protocol will be very high.
storage protocol will be very high.
Within the IBM Flex System Enterprise Chassis either option would be suitable between
storage and compute nodes. Each of the iSCSI, FCoE or FC have their attributes and
advantages over another. Performance for example, would be one attribute where separation
between the three could be measured, but such a discussion is beyond the scope of this
publication. Major determining factors in this choice of SAN will include the external
connectivity whether FC or type of Ethernet. We would favour FCoE and FC over iSCSI in the
enclosed IBM Flex System Enterprise Chassis environment as a TCP/IP within the protocol
layer is unnecessary in this environment.
