√ Major Planning Step For More Information
Plan for the Topology
Choose from one of the three supported
topologies: star, split-star, or tri-star.
Planning for the Topology
on
page 2-8
Make sure all nodes to be added to the cluster
have the software required by the chosen
topology.

Plan for Hardware
Make sure the correct number of cluster switches
are either available or will be ordered to support
the topology of the cluster you are building.
Cluster Switches Required for
Each Topology on page 2-9
If the cluster switches are not purchased
preinstalled in switch enclosures provided by HP,
make sure two 19-inch racks meeting HP
specifications are available.
Alternate Cluster Switch
Packaging on page 2-10
For each server that will join the cluster, make
sure two single-mode, fiber-optic cables meeting
HP specifications are available.
Two Fiber-Optic Cables Needed
for Each Server on page 2-10
If your cluster will use either the split-star topology
or the tri-star topology, make sure enough fiber-
optic cables (of the correct length) are available to
connect the cluster switches on each fabric.
Fiber-Optic Cables for Multilane
Links on page 2-10
Make sure infrastructure (cable-routing channels)
is available to support and route the fiber-optic
cables.
Two Fiber-Optic Cables Needed
for Each Server on page 2-10
For each server that will join the ServerNet
cluster, make sure MSEBs are installed in slots 51
and 52 of the group 01 enclosure.
Two MSEBs Needed for Each
Server on page 2-13
If MSEBs are already installed in slots 51 and 52
of group 01 of each server, verify that the MSEBs
contain a single-mode fiber-optic PIC with the
NNA FPGA in port 6.
PICs for MSEBs That Will
Replace SEBs on page 2-16
If MSEBs need to be installed, make sure the
MSEBs contain the proper complement of PICs to
support the ServerNet cables that must be
attached to them.
PICs for MSEBs That Will
Replace SEBs on page 2-16
If MSEBs need to be installed, make sure
ServerNet cables with the appropriate connectors
are available to connect the MSEBs to other
enclosures.
