A Cabling the P63x0/P65x0 EVA This appendix describes cabling instructions for the P63x0/P65x0 EVA. If you are using the P63x0/P65x0 EVA Fibre Channel controller and plan to configure it with an external iSCSI device, see the HP MPX200 Multifunction Router User Guide, which is available at: http://www.hp.com/support/manuals Under storage, select Storage Networking, and then select HP MPX200 Multifunction Router under Routers/Gateways/Multiplexers. Overview Instructions for a 2C6D configuration (2 controllers, 6 disk enclosures) are provided; these instructions can then be applied to any configuration. See Table 7 (page 66) for the minimum and maximum configurations. Table 7 Minimum and maximum configurations Array P63x0 EVA P65x0 EVA Minimum configuration 2C1D 2C2D Maximum configuration 2C10D 2C20D The cabling diagrams in this appendix show the recommended fault-tolerant cabling. Fault-tolerant cabling is recommended because it enables the controllers to access the remaining disk enclosures if an I/O module or interconnect component (for example, a cable) fails. This configuration creates two loops. For redundancy, the data path created by one of the loops starts at the top disk enclosure in the group and ends at the bottom enclosure. The other data path reverses this order; starting at the bottom disk enclosure and ending at the top enclosure. Depending on your future expansion plans and available racking space, there are different ways to arrange the controller and disk enclosures in the rack (see Figure 6 (page 22)): • Configure the controllers above the disk enclosures to maximize racking space. • Configure the controllers between the disk enclosures to ensure future ease of expansion. For information about adding disk enclosures to an existing configuration, see the HP P63x0/P65x0 EVA M6612/M6625 Disk Enclosure Installation Instructions. For information about expanding to another rack, see the HP P63x0/P65x0 Enterprise Virtual Array Expansion Rack Reference Guide. NOTE: When connecting cables, always connect cables to the same colored port (green port to green port, red port to red port). The cables shown in this document are colored green and red to easily identify connections. Use the colored cable labels (green and red) to facilitate color coding and identifying cable connections. Connecting P63x0 EVA controllers to the disk enclosures (2C6D) 1. In the default configuration for the P63x0 EVA, the disk enclosures are located below the controller enclosure. Locate the top and bottom disk enclosures. 66 Cabling the P63x0/P65x0 EVA

Overview
Instructions for a 2C6D configuration (2 controllers, 6 disk enclosures) are provided; these
instructions can then be applied to any configuration. See
Table 7 (page 66)

maximum configurations.

The cabling diagrams in this appendix show the recommended fault-tolerant cabling. Fault-tolerant
cabling is recommended because it enables the controllers to access the remaining disk enclosures
if an I/O module or interconnect component (for example, a cable) fails.
This configuration creates two loops. For redundancy, the data path created by one of the loops
starts at the top disk enclosure in the group and ends at the bottom enclosure. The other data path
reverses this order; starting at the bottom disk enclosure and ending at the top enclosure.
Depending on your future expansion plans and available racking space, there are different ways
to arrange the controller and disk enclosures in the rack (see
Figure 6 (page 22)
):
•
Configure the controllers above the disk enclosures to maximize racking space.
•
Configure the controllers between the disk enclosures to ensure future ease of expansion.
For information about adding disk enclosures to an existing configuration, see the
HP P63x0/P65x0
EVA M6612/M6625 Disk Enclosure Installation Instructions
. For information about expanding to
another rack, see the
HP P63x0/P65x0 Enterprise Virtual Array Expansion Rack Reference Guide
.
NOTE:
When connecting cables, always connect cables to the same colored port (green port to
green port, red port to red port). The cables shown in this document are colored green and red to
easily identify connections. Use the colored cable labels (green and red) to facilitate color coding
and identifying cable connections.

In the default configuration for the P63x0 EVA, the disk enclosures are located below the
controller enclosure. Locate the top and bottom disk enclosures.
