Heterogeneous storage system support
HP supports HP storage products on shared hosts, and HBAs in HP fabric environments that also have
third-party storage products. A third-party cooperative support agreement between HP Services and
the third party is required if HP will provide a single support point of contact that includes the third-party
storage. HP provides technical support for its products and cooperates with the third party's technical
support staff, as needed.
HP also provides best-practices recommendations on how to connect devices in the SAN (see
“Best practices” on page 417). These rules apply to configurations that include HP SAN storage products
and heterogeneous third-party SAN storage products:
• Use zones to isolate HP storage ports from third-party storage ports.
• Overlapping zones with multiple storage ports are not supported.
• Third-party storage zones are governed by product-specific configuration guidelines (see the third-
party product documentation).
• See “Third-party switch support” on page 179 for third-party fabric and switch support.
• See “Heterogeneous SAN storage system coexistence” on page 232 for storage system
nl
coexistence support.
Zoning
These zoning rules apply to a heterogeneous SAN with XP and VA storage systems:
• Zoning is required for all operating systems that access XP and VA storage systems.
See “Heterogeneous server rules” on page 185.
• XP and VA 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” on page 232.
Tape storage
The following rules apply to tape storage support in a SAN with XP and VA 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 with backups that 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 75 shows a configuration with XP and VA storage systems in the same fabric as tape storage.
