.Part 3 Host and Storage System Rules HP SAN Design Reference Guide 785353-001

Table 118 P9000/XP storage system rules (continued)
Description
Rule
number
XP24000/20000 and XP12000/10000 storage systems support F_Port, FL_Port, and NL_Port connectivity.
Use the following settings based on the required connectivity type:
6
• Switch/Fabric (F_Port), Fabric = On, Connection = Point to Point
• Switch/Fabric (FL_Port), Fabric = On, Connection = FC-AL
• Direct connect (no Fibre Channel switch) (NL_Port), Fabric = Off, Connection = FC-AL
See “HP P9000 (XP) Continuous Access configuration support” (page 307) for settings when using HP
P9000 (XP) Continuous Access.
Multiple operating systems and multiple clusters can be supported on the same fabric with appropriate
zoning.
7
Host zones must contain homogeneous operating system types.8
Overlapping storage port zones are supported if more than one operating system must share an array
port.
9
Heterogeneous operating systems can share an P9000/XP array port with the appropriate host group/mode
settings (see P9000/XP documentation). All others must use a dedicated P9000/XP port.
10
Servers that share access to the same storage LUN require special application software (such as cluster
software) to preserve data.
11
Zoning
These zoning rules apply to a heterogeneous SAN with P9000/XP storage systems:
• Zoning is required for all operating systems that access P9000/XP storage systems.
See “Heterogeneous server rules” (page 165).
• P9000/XP storage systems can be in multiple operating system zones.
For configurations that support common server access to multiple storage system types, see “Common
server access, different storage system types” (page 209).
Tape storage
The following rules apply to tape storage support in a SAN with P9000/XP storage systems:
• Overlapping zones are supported with disk and tape.
• Separate or common HBAs for disk and tape connections are supported.
• For a VLS, multiple heterogeneous initiators and multiple ports of the VLS device are supported
in the same fabric zone.
• HP recommends using a separate tape-to-HBA connection for servers when backups require
more than four DLT8000 tape drives or two Ultrium (LTO) tape drives.
For more information about tape storage support, contact your HP representative.
Figure 84 (page 238) shows a configuration with XP storage systems in the same fabric as tape
storage.
