IBM DCS3700, Installation, User'S, And Maintenance Manual

Page: 81 / 202

The following illustration shows multiple redundant direct-attached SAS host connections. This
configuration is also the configuration to use for a dual-node cluster configuration. Up to four hosts can
be direct attached to the DCS3700 when the optional 6Gbps 2 port SAS host interface card is installed in
each controller.
Overview of installing an IBM BladeCenter configuration to connect to
a DCS3700
This section gives an overview and guidelines for installing an IBM BladeCenter configuration to connect
to a DCS3700 storage system.
Before you install the BladeCenter configuration, consider the following information:
v
Make sure that the BladeCenter chassis, blade server, SAS connectivity module, and SAS expansion
card are supported. Go to http://www.ibm.com/systems/support/storage/ssic/interoperability.wss
and check the System Storage Interoperation Center for details of the hardware supported by the
DCS3700 storage system.
v Make sure that an Advanced Management Module is installed in the BladeCenter chassis. The latest
level of management-module firmware is available at http://www.ibm.com/bladecenter/.
v
For the latest SAS connectivity module firmware, SAS expansion card firmware, blade server BIOS
code, and device drivers, see http://www.ibm.com/systems/support/.
Installing the BladeCenter configuration
To install the IBM BladeCenter SAS Expansion Card (CFFv), IBM BladeCenter SAS Connectivity Module,
and blade server, complete the following general steps:
1. Install an IBM BladeCenter SAS Expansion Card (CFFv) in each blade server that you want to connect
to the DCS3700. See the documentation that comes with the SAS expansion card for installation
requirements and procedures.
2. Install the blade servers in the BladeCenter chassis. See the documentation that comes with the blade
server for installation requirements and procedures.
