Cabling
This section describes cabling options for high-availability multipathing configurations for
P6000/EVA storage systems.
Level 4 NSPOF configuration
Figure 77 (page 231) through Figure 80 (page 233) show cabling options when implementing a
level 4, high-availability, NSPOF configuration. For a description of availability levels, see “Data
availability” (page 38).
Figure 77 (page 231) shows the physical connections for a straight-cable, high-availability NSPOF
configuration for EVA4100/6100 storage systems. This cabling scheme supports non-HP P6000
Continuous Access configurations and HP P6000 Continuous Access configurations with
EVA4100/6100 storage systems.

Figure 78 (page 232) shows the physical connections for a straight-cable, high-availability NSPOF
configuration for EVA4400 storage systems. This cabling scheme is also supported for HP P6000
Continuous Access.
