Controller modules

The ThinkSystem DS4200 supports dual controller configurations, and the ThinkSystem DS4200 models
ship with two controller modules. The following types of controller modules are available:
DS4200 SAS Controller Modules
DS4200 FC/iSCSI Controller Modules
DS4200 SAS Controller Modules provide direct SAS attachment for up to four hosts with a supported SAS
HBA installed. Each DS4200 SAS Controller Module has four 12 Gb SAS ports with Mini-SAS HD (SFF-
8644) connectors.
DS4200 FC/iSCSI Controller Modules provide SAN based iSCSI or Fibre Channel connectivity to the hosts
with a supported software initiator or HBA installed. Each DS4200 FC/iSCSI Controller Module has two
built-in CNCs that have two SFP/SFP+ ports each for a total of four SFP/SFP+ ports per controller module.
The CNC supports the following storage connectivity protocols, depending on the SFP/SFP+ transceiver
installed or DAC cables attached:
1 Gb iSCSI with 1 GbE RJ-45 SFP optical modules
1/10 Gb iSCSI with 10 GbE SW SFP+ optical modules with LC connectors
10 Gb iSCSI with 10 GbE SFP+ DAC cables
4/8 Gb Fibre Channel with 8 Gb FC SW SFP+ optical modules with LC connectors
4/8/16 Gb Fibre Channel with 16 Gb FC SW SFP+ optical modules with LC connectors
Notes:
Both ports on the CNC on the DS4200 FC/iSCSI Controller Module must have the same connectivity
type (the same type of SFP/SFP+ modules or DAC cables).
Hybrid iSCSI and FC connectivity or 1 Gb and 10 Gb iSCSI connectivity is supported on a per CNC
basis; that is, each of two CNCs on the controller module is configured with the different types of
transceivers.
Both controller modules in the system must be of the same type, and they must have matching port
configurations (that is, the ports on both DS4200 FC/iSCSI controller modules must have SFP/SFP+
modules of the same type).
SAS controller modules and FC/iSCSI controller modules have one 12 Gb SAS x4 expansion port
(Mini-SAS HD SFF-8644 connector) for the attachment of the ThinkSystem DS Series expansion units.
