Using the NEM With Sun StorEdge 3510
and 3511 Arrays
You cannot connect the Sun StorEdge 3510 RAID array or Sun StorEdge 3511 FC
with SATA RAID array to the NEM on the same channel that use different speeds (1
Gb and 2 Gb). You can, however, mix 1-Gb and 2-Gb FC HBAs on different controller
channels. This limitation is due to the design of the Sun StorEdge 3510 RAID array's
port bypass circuitry and the inability of FC to support auto-negotiation in a multi-
drop loop configuration.
Host connectors channels 4 and 5 of the 3511 FC cannot auto-negotiate to 1 Gbit
which limits the number of hosts that can be direct-attached using 1 Gbit HBAs.
Channels 0 and 1 are able to auto-negotiate to 1 Gbit and allow up to four
connections in a dual-controller configuration or two connectors each in a single-
controller configuration.
