ISL maximums

You can use all ports on all B-series Fibre Channel switches for ISLs, with a maximum of one half

of the total ISL port count configured to the same destination switch.

NOTE: Some switches require licensing for additional ISL ports.

DC SAN Director FC8-64 cabling

The DC SAN Director FC8-64 port blade requires mSFP fiber optic cable connectors. Table 29 (page

107) describes the two possible connection scenarios and solutions for cabling.

Table 29 DC SAN Director High Density 64-port blade mSFP cabling

SolutionScenario

Use an HP mSFP-LC fiber optic cable connected directly to

the LC port of an existing LC-based switch or device to an

Connecting from an FC8-64 port blade (mSFP) to an

existing standard Fibre Channel cabling infrastructure (LC)

HP LC-LC coupler then connected to an existing LC fiber

optic cable, or to an LC patch panel.

Connecting from an FC8-64 port blade (mSFP) to another

FC8-64 (mSFP) for ISL connectivity

• Option 1: Use two mSFP-LC fiber optic cables connected

together with an LC-LC coupler.

• Option 2 (Brocade): Use an mSFP-mSFP fiber optic

cable.

Note: The mSFP-mSFP cable is not available from HP.

B-series Encryption Switch fabric rules

This section describes the fabric rules for the B-series Encryption Switches (HP StorageWorks

Encryption SAN Switch and HP StorageWorks Encryption FC Blade) and factors you should consider

when building fabrics. These switches have a built-in encryption engine and contain 8 Gb/s Fibre

Channel ports (32 for the encryption switch, 16 for the encryption blade) and two GbE ports.

Table 30 (page 107) describes the rules for creating fabrics with B-series Encryption Switches. For

more information about the security uses of these switches, see “B-series Encryption Switch and

Encryption FC Blade security” (page 377). HP strongly recommends that you read the Brocade

Fabric OS Encryption Administrator's Guide at http://h18006.www1.hp.com/storage/

saninfrastructure/switches/encrypt_sanswitch/index.html?jumpid=reg_R1002_USEN before

configuring a fabric using the encryption switch or encryption blade.

Table 30 B-series Encryption Switch fabric rules

DescriptionRule number

Encryption blade can be installed in an HP SN8000B 8-Slot SAN Backbone Director Switch, HP

SN8000B 4-Slot SAN Director Switch, DC SAN Director, or DC04 SAN Director.

There is a maximum of four encryption blades per director.2

There is a maximum of four encryption switches per encryption group.3

There is a maximum of 16 encryption engines (with four Directors, each having four encryption

engines) per encryption group.

There is a maximum of 256

physical targets per encryption switch or blade.5

There is a maximum of 1,024

physical initiators per encryption switch or blade.6
