NOTE:

• The zoning templates shown in this section refer to a single domain with DPM pair configurations

that have two or four licensed quads on the DPM. The rules and guidelines described in this section

can be applied to other configurations with multiple domains or DPM pairs with a different number

of licensed quads.

• All examples involving storage related zones in this section will use the HP EVA and HP Command

View EVA. The rules and guidelines described in this section can be applied to configurations

containing other types of multi-controller storage arrays. Zoning for the management station to

the storage device is not discussed.

Dual-fabric device configuration

HP SVSP must be deployed over a dual-fabric SAN configuration. Switches in each network are

required to be from a single vendor, although each fabric can have switches from a different vendor.

As much as possible, the fabrics should be mirror images of each other. In this section the dual-fabric

layout is referred to as the blue-fabric and the red-fabric. From a connectivity point of view, each

zone in the blue-fabric (blue zone) should have a corresponding zone in the red-fabric (red zone) that

contains the same target and initiator devices as well as number of ports for each device. At the

sub-device level, the ports of each component in the device should also be split evenly over the

mirroring fabrics. For example, a host with a single dual-port HBA should have one port mapped to

a red zone and the other port mapped to a blue zone. Similarly, in a dual-controller storage device

with two ports per controller (for example, the HP EVA4400), each controller should have a port

mapped to a red zone and the other mapped to a blue zone. Each device deployed within an HP

SVSP configuration must have at least two physical ports to provide the capability to split the device

symmetrically over the dual-fabric. Figure 5, Figure 6, Figure 7, and Figure 8 show the dual-fabric

device configuration for each HP SVSP device type.

Figure 5 Dual-fabric port configuration for 4–port and 8–port dual-controller back-end storage devices

Figure 6 DPM dual-fabric port configuration

Notice how each DPM quad has a target and initiator on both the red and blue fabrics.
