HP PCI-X 2-port 4X Fabric (DB) Adapter
The AB345A product is for use in database clusters and includes features specifically required to support and
integrate with the Oracle 10gRAC database. The AB345A can only be installed in supported Integrity servers.
What’s New
Minimum System Memory Requirements per Card
The minimum system memory requirements is 1 GB per AB345A HCA installed.
Maximum number of processes supported using AB345A HCAs
With the help of some data provided by Oracle, the following table illustrates the number of Oracle
foreground processes we can support. The table assumes that the fabric is formed in the redundant
configuration described in Figure 5-2, “Two redundant 24-port 376227-B21 switches,” of the HP Fabric
Clustering System HP-UX Administrator's Guide.
DISCLAIMER: This is an estimate that is based on some assumptions made about typical consumption of
resources by Oracle applications. You may observe a different number, if the assumptions happen to be
invalid on your specific setup
