Task 2: Inventory Your Hardware
Task 2: Inventory Your Hardware
Check that you have all the required hardware components to build your cluster.
Table 3-2 can help you inventory hardware.
For more information on these hardware components, refer to Section 2, Planning for
Installation.
Table 3-2. Hardware Inventory Checklist
√ Description Notes
Check that you have at least two MSEBs
for each node that will participate in the
cluster.
The two required MSEBs must be
installed in group 01, slots 51 and 52.
MSEBs for other enclosures are optional.
Check that the MSEBs in each group 01 of
each node contain the correct PICS.
MSEBs in group 01, slots 51 and 52 must
contain a single-mode fiber-optic NNA
PIC in port 6. Other ports must contain
the appropriate PICs to enable
connectivity to the SEBs or MSEBs to
which they connect.
Check that enough ServerNet cables are
available to replace the current
connections from group 01 to other
enclosures within each system.
These replacement cables must support
the same type of media (such as ECL) as
your current ServerNet connections.
Check that you have the correct number of
cluster switches.
You need:
•
Two cluster switches for a cluster
using the star topology. The star
topology supports up to eight nodes.
•
If this cluster will become part of a
larger split-star or tri-star topology,
you need additional cluster switches.
See Cluster Switch Requirements for
Each Topology on page 2-9.
Check that you have two fiber-optic cables
(up to 80 meters long) per node.
These cables connect group 01 to a
cluster switch.
If this cluster will become part of a split-star
or tri-star topology, check that you have
enough fiber-optic cables for the multilane
linkss.
The number of additional fiber-optic
cables depends on the topology of the
cluster. See Cluster Switch Requirements
for Each Topology on page 2-9.
If this cluster will become part of a split-star
or tri-star topology and the cables in a
multilane link will be more than 80 meters,
check that the cluster will meet the
requirements for longer cables.
Cables in a multilane link can be longer
than 80 meters if the cluster meets the
requirements in Table 2-4
on page 2-11.
