5 System Configuration Guidelines for NonStop NS2200

Systems

This section provides configuration guidelines and configuration restrictions for a NonStop NS2200

commercial system. Configuration restrictions are also described in Chapter 6 (page 103).

Internal ServerNet Interconnect Cabling

This subsection includes:

• “Dedicated Service LAN Cables” (page 88)

• “Cable Length Restrictions” (page 88)

• “Cable Product IDs” (page 88)

• “Blade Element to VIO Enclosure” (page 88)

• “Processor ID Assignment for the Blade Element” (page 89)

• “SAS Ports to SAS Disk Enclosures” (page 89)

• “SAS Ports to SAS Tape Devices” (page 89)

• “Fibre Channel Ports to ESS” (page 89)

• “Fibre Channel Ports to Tape Devices” (page 89)

Dedicated Service LAN Cables

The NonStop NS2200 commercial system uses Category 5e (CAT 5e) or Category 6 (CAT 6),

unshielded twisted-pair Ethernet cables for the internal dedicated service LAN and for connections

between the VIO enclosure and the application LAN equipment.

Cable Length Restrictions

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

Product IDMaximum LengthConnectorsFiber TypeConnection

M8900nnn

250 mLC-LCMMFVIO enclosure (FC

HBA interfaces on

Storage CLIM) to ESS

M8900nnn250 mLC-LCMMFVIO enclosure (FC

HBA interfaces on

Storage CLIM) to FC

switch

nnn indicates the length of the cable in meters. For example, M8900250 is 250 meters long

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

recommends that cable length between each of the enclosures be as short as possible.

Cable Product IDs

For product IDs, see Appendix B (page 172).

Blade Element to VIO Enclosure

Fiber-optic cables provide communication between the ServerNet PCI adapter card in each blade

element and the ServerNet-to-processor ports on the VIO enclosure. The optional Fibre Channel

HBA interfaces on the Storage CLIM provide storage and I/O connectivity and the Ethernet ports
