Chapter 5
Set Up the BS2000 Server
for ETERNUS DX/AF Storage Systems
The ETERNUS DX/AF storage system is configured in the same way as any other disk subsystem with host
connection via FC supported by BS2000.
5.1

SE Server (SU /390)

Set up the SE Server for BS2000 disks on an ETERNUS DX/AF storage system.
An affinity group is generated on the SE Server as a logical controller. A maximum of 4 FC channels is
recommended, up to 8 FC channels are supported.
A maximum of 4096 LUNS is supported per channel path. However, we recommend assigning significantly
fewer volumes to an affinity group, thus enabling PAV alias devices to be generated on the same channel
path.
Please be aware that if there are up to 4096 LUNs per channel path, the number of host FC ports per CA port is
limited to 32 for the storage system.
For performance reasons each volume should be configured with one or two additional PAV alias devices.
D3435 (internal type A5) must be specified as disk device type. (See manual "BS2000 System Installation" and
the example in the annex.)
5.2

S-Server

Set up the S-Server for BS2000 disks on an ETERNUS DX/AF storage system.
An affinity group is generated on the S-Server as a logical controller on a maximum of 8 FC channels.
A maximum of 256 LUNS is supported per channel path. However, we recommend assigning significantly
fewer volumes to an affinity group, thus enabling PAV alias devices to be generated on the same channel
path.
For performance reasons each volume should be configured with one or two additional PAV alias devices.
D3435 (internal type A5) must be specified as disk device type. (See manual "BS2000 System Installation" and
the example in the annex.)
