iSCSI over DCB support (SC, SCv and PS Series)

3.4 iSCSI over DCB support (SC, SCv and PS Series)
The following table indicates switches that have been tested with each array family’s native iSCSI over DCB
features.
SC Series arrays, with the release of SC Operating System (SCOS) 7.0 now support iSCSI over DCB. With
this support, the SC series supports the following DCB standards:
• IEEE 802.1Qbb – Priority Flow Control
• IEEE 802.1Qaz – Enhanced Transmission Selection
• IEEE 802.1Qaz – Data Center Bridging Exchange Protocol (IEEE DCBx)
Note: SC Series arrays do not support pre-IEEE DCBx standards such as converged enhanced Ethernet
(CEE) or data center Ethernet (DCE) for iSCSI over DCB functionality. Switches that are listed in the table
below that only support these pre-IEEE versions are designated as “L4” indicating there is “No Support”.
Note: SC Series iSCSI over DCB is supported on controllers using the Chelsio T5xxx iSCSI Adapters at this
time.
