Controller B
A RAID chassis accommodates two power supply FRUs of the same type — either both AC or both DC —
within the two power supply slots (see two instances of callout No.1 above). The RAID chassis
accommodates two controller I/O modules (IOMs)of the same type within the IOM slots (see callouts No.2
and No.3 above).
Caution:
Dual controller configurations are supported. Single configurations are supported only when
a controller fails over to its partner . A controller must be installed in each IOM slot to ensure sufficient
airflow through the chassis during operation.
Note:
The chassis support hot-plug replacement of redundant controller IOMs, fans, power supplies,
and expansion modules. Hot-add replacement of drive chassis is also supported.
2U12, 2U24, and 2U48 Controller I/O Module – Rear
Panel Components
The Controller I/O Module has two model types, converged network (CNC) ports or HD mini-SAS. The
models can be configured as follows:
l
Host CNC ports configured with SFPs supporting the following:
o
4/8/16 Gb FC
o
10GbE iSCSI
o
1 Gb RJ-45
l
Host interface ports configured with 12 Gbit/s HD mini-SAS (SFF-8644) connectors.
Note:
Xcellis, StorNext, and QX controller IOMs support FC host attach only.
Host CNC Ports Configured with SFPs (FC or iSCSI)
The following figure shows CNC ports configured with SFP+ transceivers that support 4, 8, or 16 Gb FC, or
10 GbE iSCSI connections. The SFPs look identical. Refer to the CNC LEDs that apply to the specific
configuration of your CNC ports.
