System Console
Details about the use or implementation of the maintenance switch that are specific to
an Integrity NonStop NS1000 server are presented here.
The Integrity NonStop NS1000 system requires multiple connections to the
maintenance switch:
•
One connection to each of the two ServerNet switch boards in the IOAM enclosure
•
At least two connections to the G4SAs installed in the IOAM enclosure for the
OSM Service Connection and OSM Notification Director:
°
One connection for the system console running OSM
System Console
A system console is a personal computer (PC) running maintenance and diagnostic
software for Integrity NonStop NS1000 systems. When supplied with a new NonStop
system, system consoles have factory-installed HP and third-party software for
managing the Integrity NonStop NS1000 system. You can install software upgrades
from the HP NonStop System Console Installer CD.
Some system console hardware, including the PC system unit, monitor, and keyboard,
can be mounted in the Integrity NonStop NS1000 system’s 19-inch rack. Other PCs
are installed outside the rack and require separate provisions or furniture to hold the
PC hardware.
For more information on the system console, refer to System Console on page B-1.
Enterprise Storage System
An Enterprise Storage System (ESS) is a collection of magnetic disks, their controllers,
and the disk cache in one or more standalone cabinets. ESS connects to the Integrity
NonStop NS1000 system either directly via FCSAs in an IOAM enclosure (direct
connect) or through a separate storage area network (SAN) using a Fibre Channel
SAN switch (switched connect). For more information about these connection types,
see the Fibre Channel ServerNet Adapter Installation and Support Guide.
High availability and a fault-tolerant configuration for one IOAM enclosure and pairs of
FCSAs are similar to the configurations required for Fibre Channel disk drives, as
explained in IOAM Enclosure and Disk Storage Considerations on page 6-9.
Cables and switches vary, depending on whether the connection is direct, switched, or
a combination:
Connection LC-LC Cables Fibre Channel Switches
Direct-connect 2 per FCSA 0
Switched 4 per FCSA 1 or more
Combination of
direct and switched
2 per FCSA for each direct connection
4 per FCSA for each switched connection
