NonStop NS14000 Series Planning Guide (H06.13+)

4 System Configuration Guidelines

Integrity NonStop NS14000 series systems use a flexible modular architecture. Therefore, almost

any configuration of the system’s modular components is possible within a few configuration

restrictions stated in “Enclosure Locations in Cabinets” (page 84) and “VIO Enclosure and Disk

Storage Considerations” (page 72).

NOTE: For NonStop NS14000 series servers that contain I/O Adapter Module (IOAM) enclosures,

refer to the H06.07 (or earlier) version of this manual for planning, configuration, and maintenance

information of the IOAM enclosure.

For other example configurations, see Chapter 5 (page 84).

• “Length Restrictions for Optional Cables” (page 68)

• “Internal Cable Product IDs” (page 68)

• “NonStop Blade Elements to LSU” (page 69)

• “LSU to VIO Enclosure and Processor IDs” (page 69)

• “VIO Enclosure ServerNet Connections” (page 71)

• “Fibre Channel Port to Fibre Channel Disk Modules” (page 72)

• “Fibre Channel Port to Tape Devices” (page 72)

Dedicated Service LAN Cables

The NonStop NS14000 series system uses Category 5e unshielded twisted-pair (CAT 5e UTP) or

Category 6 unshielded twisted-pair (CAT 6 UTP) Ethernet cables for the internal dedicated service

LAN and for connections between the VIO enclosure and the application LAN equipment.

Length Restrictions for Optional Cables

Maximum allowable lengths of cables connecting to components outside the modular cabinet are:

Product IDMaximum LengthConnectorsCable TypeConnection

M8900nnn

250 mLC-LCMMFVIO enclosure (Fibre

Channel port) to ESS

M8900nnn

250 mLC-LCMMFVIO enclosure (Fibre

Channel port) to FC

switch

nnn indicates the length of the cable in meters. For example, M8900125 is 125 meters long; M8900-15 is 15 meters

long. For a complete list of cables, see “Cable Types, Connectors, Length Restrictions, and Product IDs” (page 94).

Although a considerable cable length can exist between the modular enclosures in the system, HP

recommends placing all cabinets adjacent to each other and bolting them together, with cable

length between each of the enclosures as short as possible.

Internal Cable Product IDs

For product IDs, see “Cable Types, Connectors, Length Restrictions, and Product IDs” (page 94).
