Adapter Plug Order For The Ds8700 (4-Port) And The Ds8800 (4-Port And 8-Port ) In A Ha Configuration - IBM DS8800 Introduction And Planning Manual

Host adapter intermix support
Both 4-port and 8-port host adapters (HAs) are available in the DS8800. The
DS8700 supports only the 4-port HA, but like the DS8800, it can use the same 8
Gbps, 4-port HA for improved performance.

Figure 11. Adapter plug order for the DS8700 (4-port) and the DS8800 (4-port and 8-port ) in a HA configuration.
Figure 12 on page 32 also shows the adapter plug order for the DS8700 and
DS8800 using a 4-port or 8-port HA configuration.
The DS8700 supports a 4-port, 4 Gbps or 8 Gbps HA plugged into either
the C1 or C4 slots of the I/O enclosures, slots C2 and C5 only support 4
Gbps HA.
If all of the C1 and C4 slots are occupied by a previously installed 4 Gbps
HA, you can remove the existing HA from the C1 or C4 slot to install the
4-port 8 Gbps HA. The removed 4 Gbps HA might be reinstalled to an
available C2 or C5 slot. The DS8700 can support up to 128 Fibre Channel
ports, but only 64 of those can be 8 Gbps.
The DS8800 supports both 4-port and 8-port, 8 Gbps HAs. It does not
support 4 Gbps HAs. The position and the plug order in the I/O enclosure
of the storage unit is the same as the DS8700. No HAs are supported in
slots C2 and C5.
