Appendix A. High Availability Solutions

The RS/6000 High Availability Cluster Server - High Availability Solution is a two-
node high-availability cluster consisting of two Model H Series Drawer drawers and
one or two 7133 Serial Disk Systems mounted in a 7014 Model S00 Rack with two
power distribution units. Each Model H Series Drawer comes with AIX system soft-
ware and HACMP high-availability cluster software. The base High Availability Sol-
ution system uses and shares the external SSA disks in the Model 7133 SSA Disk
Storage Subsystems.
Each RS/6000 High Availability Cluster Server - High Availability Solution includes
required PCI SSA disk adapters, SSA cabling, two 10/100 Mbs Ethernet PCI
adapters, one Ethernet transceiver, one CD-ROM, one AIX (1-2 user) license and
one HACMP license. It is highly recommended that a 3153 ASCII terminal (or equiv-
alent) be purchased even if graphics adapters or remote work stations are used as
the control console. This will permit a software or service person to work on one
CPU through the serial port without affecting the other CPU or applications. If a
graphical display is preferred to the 3153 display, a low cost workstation can be con-
nected to one of the Ethernet transceivers or into the local network.
The 7133 Serial Disk System comes with eight SSA disk drives on two loops and a
redundant AC power supply
Two additional SSA adapters can be put in each Model H Series Drawer.
