SAN fabric switch interoperability rules

HP supports two heterogeneous switch SAN configurations:

• Dual interoperable, heterogeneous SAN fabrics

• Interoperable, heterogeneous switch fabrics

Dual interoperable, heterogeneous SAN fabrics

A dual interoperable, heterogeneous SAN consists of two fabrics, with each fabric comprised

exclusively of switches from a different series.

HP supports dual interoperable SAN fabrics for the following switch-series combinations:

• A SAN with one fabric containing B-series switches only and a second fabric containing

C-series switches only

• A SAN with one fabric containing B-series switches only and a second fabric containing

H-series switches only

When creating a dual interoperable, heterogeneous SAN, consider the following:

• HP recommends that you use the same fabric topology and configuration in both fabrics to

maintain balanced SAN performance.

• HA configurations require support for common HBA, driver, multipathing software, and storage

array firmware versions because servers and storage connect to both fabrics.
