3. Install the IBM BladeCenter SAS Connectivity Modules in the I/O bays in
BladeCenter unit. See the documentation that comes with the SAS connectivity
modules for installation requirements and procedures.
4. Go to “Connecting BladeCenter hosts to the DS3200.”
Connecting BladeCenter hosts to the DS3200
The dual-controller DS3200 comes with one SAS host connector on each controller,
enabling up to 14 blade servers in one BladeCenter unit to be redundantly
connected to the DS3200.
To protect against the loss of any one path from the host blade servers to the
DS3200, use redundant host connections. Figure 31 shows the locations of
controllers A and B and the host connectors at the rear of the DS3200.
To connect a SAS expansion card that is installed in a blade server to the DS3200,
complete the following steps:
1. Connect a SAS cable from the SAS host connector on the DS3200 RAID
controller to any SAS port on an IBM BladeCenter SAS Connectivity Module
that is installed in a BladeCenter unit.
Attention: The optional SAS host port adapter with its two additional SAS
connectors is not supported in this configuration. You must use the SAS host
connector on the controller.
2. To create a redundant host connection, connect a SAS cable from a second
SAS connectivity module to a host connector on the other RAID controller in the
DS3200. You can create a maximum of two redundant host connections in a
dual-controller DS3200.
Attention: You can connect only one DS3200 to the BladeCenter SAS
Connectivity Module. No other external devices can be connected to the SAS
connectivity module.
3. (Optional) For additional storage, you can connect EXP3000 storage expansion
enclosures to the DS3200. For an illustration showing how to configure the
storage expansion enclosures, see Figure 18 on page 27.
