Product Description
Hardware/Software Requirements
The disk system is supported on the following operating systems:
■ HP-UX 11.00 with HWE 0302 or greater
■ HP-UX 11.11 with HWE 0302 or greater
For supported servers, see the latest HP 9000 Configuration and Ordering Guide.
One of the following Fibre Channel HBAs must be installed in the host:
■ A5158A, 1 Gb PCI Fibre Channel HBA
■ A6684A, 1 Gb HSC Fibre Channel HBA
■ A6685A, 1 Gb HSC Fibre Channel HBA
■ A6795A, 2 Gb PCI FIbre Channel HBA
Topologies
The disk system supports high availability through redundant components and
redundant connections to redundant hosts. Each port on a LCC can be connected
to a different host bus adapter in the same or different hosts. Mirroring inside a
disk system is not a high availability solution to the extent that a midplane failure
would necessitate downtime.
Basic high availability topologies are described on the following pages. For
information about specific supported topologies, consult an HP sales
representative.
