A EVA6400/8400 cabling diagrams

This appendix contains cabling diagrams for common EVA6400/8400 installation environments. If
you plan to configure the EVA6400/8400 with an iSCSI device, see the HP StorageWorks EVA iSCSI
connectivity user guide. See

Connecting device port Fibre Channel cables to the
EVA6400/8400 (rear view)

Depending on your future expansion plans and available racking space, there are two ways to connect
EVA6400/8400 controllers to the disk enclosure:

• Configure the controllers above the disk enclosures to maximize racking space

• Configure the controllers in the middle of the disk enclosures to ensure future ease of expansion

The following list describes the labeling and coloring used on the diagrams:

• DP1-x/DP2-x—The -A and -B data ports on each controller

• I/O-x—The -A and -B I/O modules on each disk enclosure

• P1/P2—The ports on the I/O module within each disk enclosure

• Shelf-x (S-x)—The numbered label for each disk enclosure in the configuration

• MP1–MP2 – Jumper Cables—The black cables used to connect the controllers

• Yellow numbered labels (01, 02, etc.)—These labels correspond to the white callout labels along

the sides of the diagram and indicate the connection between the controller data port and disk
enclosure port on a specific disk enclosure.

• Top of Loop—Indicates that the cable connection belongs in the top loop

Bottom of Loop—Indicates that the cable connection belongs in the bottom loop

• Green and red cables—The colored cables correspond with the physical cables used to make the

connections. Green labeled cables are used on the left side of the configuration; red labeled
cables are used on the right side of the configuration.

NOTE:

As a best practice, ensure the disk enclosures are balanced across the loops.

For EVA6400 configurations with the controllers above the disk enclosures, attach the cables as shown
in

Figure 16, Figure 17, and Figure 18. For EVA6400 configurations with the controllers in between

the disk enclosures, attach the cables as shown in

Figure 19, Figure 20, and Figure 21.

For EVA8400 configurations with the controllers above the disk enclosures, attach the cables as shown
in

Figure 22, Figure 23, Figure 24, and Figure 25. For EVA8400 configurations with the controllers

in between the disk enclosures, attach the cables as shown in

Figure 26, Figure 27, Figure 28, and

Figure 29.
