Figure 5-5 shows an example of using method 2 cabling to connect two
Storage Hubs, FC-AL Switches, or Fibre Channel SAN Switches to RA4000
Array Controllers in two RA4000/RA4100 Arrays.

Figure 5-5. Method 2: cabling an active/active configuration with two
RA4000/RA4100 Arrays
NOTE: When defining the active array controllers as instructed later in this chapter, for
method 1 cabling make the top array controller in each RA4000/RA4100 Array the active
controller. For method 2 cabling, make the top array controller in odd-numbered
RA4000/RA4100 Arrays the active controller; make the bottom array controller in even-
numbered RA4000/RA4100 Arrays the active controller.
To cable the Storage Hubs, FC-AL Switches, or Fibre Channel SAN Switches
to the RA4000 Array Controllers in an active/active configuration:
1. Using Fibre Channel cables, connect Storage Hub/Switch #1 to the
active RA4000 Array Controller in odd-numbered RA4000/RA4100
Arrays (RA4000/RA4100 Array #1, RA4000/RA4100 Array #3, and
RA4000/RA4100 Array #5).
2. Using Fibre Channel cables, connect Storage Hub/Switch #1 to the
standby RA4000 Array Controller in even-numbered RA4000/RA4100
Arrays (RA4000/RA4100 Array #2 and RA4000/RA4100 Array #4).
3. Using Fibre Channel cables, connect Storage Hub/Switch #2 to the
active RA4000 Array Controller in even-numbered RA4000/RA4100
Arrays.
4. Using Fibre Channel cables, connect Storage Hub/Switch #2 to the
standby RA4000 Array Controller in odd-numbered RA4000/RA4100
Arrays.
