HP StorageWorks Scalable File Share System Installation and Upgrade Guide Version 2.2

Preparing for the installation2–24
• If the InfiniBand interconnect is partitioned, you may define multiple interfaces (one for each partition
where the HP SFS system will be used) and you have the facility to provide a Pkey value for each
interface.
The InfiniBand network information is entered at the Configure InfiniBand Interconnect menu
during installation (see Section 6.8.2.3 or Section 7.4.2.3, depending on the type of storage used).
2.4.4 Assigning ports on a Quadrics interconnect
If you are using a Quadrics interconnect to connect the servers in the HP SFS system to the client nodes, you
may connect the servers to any port on the Quadrics interconnect. For convenience, you may want to assign
servers to a contiguous port range. However, the software does not require this.
In addition, consider reserving ports for future expansion of the system (that is, by adding more servers).
2.4.5 Determining the Quadrics machine ID
NOTE: Use the worksheet in Table B-4 in Appendix B to record the information you gather in this section.
All hosts on a Quadrics interconnect that wish to communicate with each other must use the same
machine ID. By default, hosts of the same architecture type have the same machine ID.
If you are using a Quadrics interconnect to connect the servers in the HP SFS system to the client systems,
determine the machine ID of your client systems before you install the HP SFS system; you can find this
information by entering the following command on a client node:
# cat /proc/qsnet/ep/config/machine_id
By default, the servers in the HP SFS system have a machine ID consistent with HP XC systems on Cluster
Platform 6000, which consist of HP Integrity rx2600 nodes. During the installation, the machine ID used by
the HP SFS servers is displayed on the Configure Quadrics Interconnect menu. If the machine ID
used by the servers is different from the machine ID used by your client systems, you must change the
machine ID on the servers. You can make this change at the Configure Quadrics Interconnect
menu during the installation (see Section 6.8.2.5 or Section 7.4.2.5, depending on the type of storage
used).
Typical circumstances where the machine ID used by the HP SFS servers may be different to the machine ID
used by the client systems include the following:
• Some of the client systems are not ia64 hosts.
• You are running several distinct clusters on the same Quadrics interconnect.
2.4.6 Assigning ports on a Myrinet interconnect
Two types of Myrinet interconnect are supported: Myrinet XP and Myrinet 2XP. When a Myrinet 2XP
interconnect is used to connect the servers in the HP SFS system to the client nodes, there are two connections
from each server to the interconnect. For detailed wiring instructions, refer to the HP StorageWorks Scalable
File Share for EVA4000 Hardware Installation Guide or the HP StorageWorks Scalable File Share for SFS20
Enclosure Hardware Installation Guide (depending on the type of storage used).
If you are using a Myrinet XP interconnect, you may connect the servers to any port on the Myrinet
interconnect. For convenience, you may want to assign servers to a contiguous port range. However, the
software does not require this.
In addition, consider reserving ports for future expansion of the system (that is, by adding more servers).
