SC8000 SAS Port Types

There are two types of controller SAS ports: initiator only and initiator/target. SAS chains
begin with an initiator port. As shown in the following figure, ports 1–2 (circled in blue) on
SAS IO cards are initiator only, and ports 3–4 (circled in red) are initiator/target.
Figure 52. Controller SAS Port Types
1 Initiator Only (Ports 1–2)
2 Initiator/Target (Ports 3–4)

Connect IPC for Dual-Controller Storage Centers

If you are configuring a dual‐controller Storage Center, connect the controllers with a
Category (Cat) 6 Ethernet cable. If the Storage Center only uses a single SAS chain, you
must also interconnect the controllers with additional SAS connections to make sure that
sufficient IPC bandwidth is available.
