Section 3
Customizing the Server Configuration
This section discusses issues you should consider for customizing the configuration of
your FS6200 Server. You should perform these tasks after your service representative
completes setting up the FS6200 Server.
Configuring I/O
This subsection provides topics you should consider when setting up your I/O
configuration on the FS6200 Server.
Configuring Storage
The FS6200 Server supports Virtual Sector Size (VSS) disks on external storage. Logical
disks are not supported on external storage.
Storage systems with VSS disks, including active-active and active-passive disk storage
systems, are fully supported by the FS6200 Server MCP.
You access the OCManager installed in the systems management engine environment to
display useful I/O subsystem information. However, you should not use it to adjust system
settings unless directed by Unisys support. In particular, do not set persistent binding on
the storage logical units (LUNs).
The Fibre Channel Host Bus Adapters (HBAs) are available for your configuration. Refer to
the Server External Disk and Tape Storage Systems Configuration Guide for details.
There are four PCIe slots per ISM available that can be used for up to three HBAs or NICs
in any combination. Each HBA has four Fibre Channel ports. Therefore, there are up to 24
Fibre Channel ports which is the maximum number of ports. The Fibre Channel HBA ports
can be used to access a disk storage system. Direct connect and fabric configurations are
both supported. In the case of a fabric configuration, each HBA port can be given access to
either one or two taps in the storage system.
For a resilient storage system configuration, at least two HBA cards in separate ISMs must
have paths that provide access to the storage system and these paths should make use of
storage ports in at least two storage processors/directors within the storage system. In a
fabric configuration, the best resiliency requires having those paths traverse two physically
separate fabrics. An external halt/load unit with paths from each ISM should be configured
for production use of the server.
