General EVA6400 expansion cabling guidelines To adapt the cabling used in Figure 23 to different configurations, follow these cabling guidelines: • Controller A • DP1-A on controller A connects to P1 (I/O-A) on the top disk enclosure in the first loop (expansion rack). • DP2-A on controller A connects to P1 (I/O-A) on the top disk enclosure in the second loop (expansion rack). • DP1-B on controller A connects to P2 (I/O-B) on the bottom disk enclosure in the first loop (main rack). • DP2-B on controller A connects to P2 (I/O-B) on the bottom disk enclosure in the second loop (main rack). • Controller B • DP1-A on controller B connects to P2 (I/O-A) on the bottom disk enclosure in the first loop (main rack). • DP2-A on controller B connects to P2 (I/O-A) on the bottom disk enclosure in the second loop (main rack). • DP1-B on controller B connects to P1 (I/O-B) on the top disk enclosure in the first loop (expansion rack). • DP2-B on controller B connects to P1 (I/O-B) on the top disk enclosure in the second loop (expansion rack). • Disk enclosures • P1 (I/O-A) on the top disk enclosure in the first loop (main rack) connects to P2 (I/O-A) on the bottom disk enclosure in the first loop (expansion rack). • P1 (I/O-A) on the top disk enclosure in the second loop (main rack) connects to P2 (I/O-A) on the bottom disk enclosure in the second loop (expansion rack). • P1 (I/O-B) on the top disk enclosure in the first loop (main rack) connects to P2 (I/O-B) on the bottom disk enclosure in the first loop (expansion rack). • P1 (I/O-B) on the top disk enclosure in the second loop (main rack) connects to P2 (I/O-B) on the bottom disk enclosure in the second loop (expansion rack).

General EVA6400 expansion cabling guidelines
To adapt the cabling used in
Figure 23
to different configurations, follow these cabling guidelines:
•
Controller A
•
DP1-A on controller A connects to P1 (I/O-A) on the top disk enclosure in the first loop (expan-
sion rack).
•
DP2-A on controller A connects to P1 (I/O-A) on the top disk enclosure in the second loop
(expansion rack).
•
DP1-B on controller A connects to P2 (I/O-B) on the bottom disk enclosure in the first loop (main
rack).
•
DP2-B on controller A connects to P2 (I/O-B) on the bottom disk enclosure in the second loop
(main rack).
•
Controller B
•
DP1-A on controller B connects to P2 (I/O-A) on the bottom disk enclosure in the first loop
(main rack).
•
DP2-A on controller B connects to P2 (I/O-A) on the bottom disk enclosure in the second loop
(main rack).
•
DP1-B on controller B connects to P1 (I/O-B) on the top disk enclosure in the first loop (expansion
rack).
•
DP2-B on controller B connects to P1 (I/O-B) on the top disk enclosure in the second loop (ex-
pansion rack).
•
Disk enclosures
•
P1 (I/O-A) on the top disk enclosure in the first loop (main rack) connects to P2 (I/O-A) on the
bottom disk enclosure in the first loop (expansion rack).
•
P1 (I/O-A) on the top disk enclosure in the second loop (main rack) connects to P2 (I/O-A) on
the bottom disk enclosure in the second loop (expansion rack).
•
P1 (I/O-B) on the top disk enclosure in the first loop (main rack) connects to P2 (I/O-B) on the
bottom disk enclosure in the first loop (expansion rack).
•
P1 (I/O-B) on the top disk enclosure in the second loop (main rack) connects to P2 (I/O-B) on
the bottom disk enclosure in the second loop (expansion rack).

shows a fully cabled EVA8400 2C6D main rack configuration. The
multi-product rack example assumes that there is non-EVA hardware in the rack above the controllers.
