Complete this task to connect the host adapter to the server enclosure processor cards.
- Connect the host system cables to the server enclosure processor card or to switches. Figure 1 shows the location on the processor cards where the host system cables connect.
Use the examples in the following diagrams to connect hosts to the DS6000™ using
switches. When you use external fibre-channel switches, the DS6000 supports up to 1040 host attachments.
Figure 2 shows an example of a dual path configuration using fibre-channel
switches. Host 1 contains two host bus adapters that are connected to the
servern enclosure processor cards. To configure a host with dual path redundancy,
connect the first host bus adapter (HA1) to SW1 and connect the second host
bus adapter (HA2) to SW2. Then, connect SW1 to the upper server enclosure
processor card and SW2 to the lower server enclosure processor card.
You can directly attach up to four
fibre-channel switches to a DS6000. Figure 3 shows an example
of attaching four fibre-channel switches.
If the configuration requires more
hosts than four fibre-channel switches can support, you must add cascading
switches, as shown in Figure 4.
