Configuration rules for I/O adapter features
To order I/O adapter features, you must follow specific configuration rules.
The following configuration rules affect I/O adapter features:
v
Configuration rules for I/O enclosures, I/O cables, and device adapters
v Configuration rules for host adapters and host adapter cables
Configuration rules for I/O enclosures, I/O cables, and device
adapters
Use these configuration rules and ordering information to help you order I/O
enclosures, I/O cables, and device adapters.
You must consider your entire storage system (base model and any attached
expansion units) when you order. Every disk enclosure pair must be populated
with either 16, 32, or 48 disk drives. If a disk enclosure pair is populated with only
16 or 32 disk drives, it must be populated with one or two disk enclosure filler sets
(feature #2999).
Use Table 29 on page 110 and Table 30 on page 111 to determine the number of
I/O enclosures and device adapters features that you need in various storage unit
configurations. To use the table, find the rows that contain the type of storage unit
you are configuring. Then find the row that represents the number of disk
