Table 27 B-series Fibre Channel switch fabric rules (continued) Rule number 6 Description B-series switches and routers supported routing modes with Continuous Access products: • HP P9000 (XP) Continuous Access—Supported with port-based routing (aptpolicy = 1) or exchange-based routing (aptpolicy = 3). See “HP P9000 (XP) Continuous Access FCIP gateway support” (page 314). • HP P6000 Continuous Access—Supported with port-based routing (all XCS versions) or exchange-based routing (XCS 09534000 or later).
Table 27 B-series Fibre Channel switch fabric rules (continued) Rule number Description For HP P9000 (XP) Continuous Access, see “HP P9000 (XP) Continuous Access FCIP gateway support” (page 314). 11 Within a fabric, assign a unique domain number (domain ID) and a unique WWN to each switch. All switch configuration parameters for the same switch models must be the same. Do not configure any switches with a domain ID of 8, which is reserved for HP-UX.
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.

These fabric rules apply to SANs that include the same operating systems and storage products as the B-series switches.
Table 31 1606 Extension SAN Switch and DC Dir Switch MP Extension Blade fabric rules (continued) Rule number 11 Description FCIP tunnels (virtual E_Ports) pass traffic between the SAN extension devices. • The 1606 Extension SAN Switch supports up to 8 FCIP tunnels. • The DC Dir Switch MP Extension Blade supports up to 20 FCIP tunnels. 12 IPsec is supported on the 1606 Extension SAN Switch beginning with firmware 6.3.1a. See Rule 18.
• Front phantom domains—All EX_Ports on a Fibre Channel router that are connected to the same edge fabric are presented as a single front phantom domain. • Translate phantom domains—Assigned to each remote fabric connected to a 1606 Extension SAN Switch, DC Dir Switch MP Extension Blade, 400 MP Router, or MP Router Blade. Each fabric has one unique translate domain, regardless of how many EX_Ports are connected to the fabric.
about configuring MP Routers for FCIP, see “B-series 400 MP Router and MP Router Blade” (page 290). Table 32 (page 111) describes the rules for creating fabrics with Fibre Channel routing using 8 Gb/s switches, 400 MP Routers, and MP Router Blades. Table 32 Integrated Fibre Channel routing, 400 MP Router, and MP Router Blade fabric rules Rule number Description 1 The MP Router Blade supports only the DC SAN Backbone Director, DC04 SAN Director, and SAN Director 4/256.
Table 32 Integrated Fibre Channel routing, 400 MP Router, and MP Router Blade fabric rules (continued) Rule number Description • FCFW does not work in FICON environments. • FCFW flows may be routed to another 400 MPR or MP Router blade on the FC network. This 400 MPR or MP Router blade may have active FCIP tunnels over an IP network. FCFW flows may be passed through the FCIP tunnel, but only if the FCIP FastWrite option is disabled on the tunnel.

Contact your HP representative for further details.
Table 34 MP Router fabric rules (continued) Rule number Description 4 The MP Router is not supported for use as a Fibre Channel switch. Direct device connectivity to MP Router ports (F_Port) is only supported with iSCSI. See “iSCSI storage” (page 318). You can configure a Fibre Channel port as an E_Port, EX_Port (Fibre Channel Routing), GbE iSCSI, or GbE FCIP.

XPath OS compatibility Table 20 (page 94) through Table 22 (page 95) list the B-series switches and firmware versions that are supported in a SAN with the MP Router XPath OS. Scalability rules Table 35 (page 118) lists the scalability rules for Meta SANs using the MP Router. The following terms describe MP Router scalability: • Front phantom domains—Individual EX_Port connections from the MP Router to the edge fabrics. • Translate phantom domains—Assigned to each remote fabric connected to an MP Router.
MP Router hop count The MP Router counts the same as a Fibre Channel switch is counted with respect to fabric hop count. See Figure 55 (page 119). Devices communicating across fabrics through an MP Router must adhere to both the B-series 7-hop limit within an edge fabric and the MP Router 12-hop limit.
Core switch addressing mode B-series Fibre Channel switches using firmware 4.1 (or later) and all MP Router models are shipped with the Core switch PID parameter bit set to 1. Legacy switches using firmware 4.0 or 3.1 (or earlier) were shipped with this bit set to 0, which limited the number of switches in a fabric and the number of ports on a switch. HP recommends that you set the Core switch PID parameter bit to 1 in all B-series fabrics. Use the configure command to modify the Core switch PID setting.

Multiprotocol and Multiservice products are designated with the i suffix, such as the MDS 9216i and MDS 9222i, or as IP storage services modules, such as the IPS-4, IPS-8, 14/2, and 18/4.

7 H-series switches and fabric rules This chapter describes the fabric rules for the HP H-series switches. It describes the following topics: • “H-series switches” (page 140) • “Fabric rules” (page 144) H-series switches The SN6000 Fibre Channel Switches: • Can be used as core or edge switches. When configured in a core-edge fabric topology, a core switch typically connects to other switches in the SAN; an edge switch typically connects to servers and storage.
Model numbering The SN6000 Fibre Channel Switch uses the numbering scheme of SN6xxx, which indicates a mid-range size switch type. The 8/20q Fibre Channel Switch uses the numbering scheme x/y: • x—The highest speed at which the switch ports can operate, measured in Gb/s • y—The total number of switch ports available For example, the 8/20q Fibre Channel Switch is an 8 Gb/s switch with up to 20 ports. Model naming The SN6000 Fibre Channel Switch is available as a standalone switch.

Usage The H-series switches can be used as core or edge switches in fabrics with up to 600 ports (including 8 Gb ISLs, but not including 10 Gb/20 Gb stacking port ISLs). The TR feature allows you to connect H-series switches to B-series or C-series fabrics, enabling the sharing of server and storage resources between fabrics through the industry-standard NPIV protocol. Fabric rules This section describes the SAN fabric rules that apply to all H-series switch SANs.
Servers, operating systems, and storage products The fabric rules for H-series switches apply to SANs that include the servers, operating systems, and storage products listed in Table 53 (page 145).
Table 54 H-series switches fabric rules (continued) Rule number Description 3 8/20q Fibre Channel Switch supports from 8 to 20 8 Gb/s ports, in 4-port increments; SN6000 Fibre Channel Switch supports 8 to 20 8 Gb/s ports, in 4-port increments, plus 4 stacking ports. 4 Within a fabric, if you assign a domain number (domain ID), it must be unique. Do not configure any switches with a domain ID of 8, which is reserved for HP-UX.
Table 55 (page 147) describes the supported remote fabric switches you can use to connect to an H-series switch TR_Port.

use of duplex couplers, provided that you do not exceed the overall cable loss budget for that cable segment. HP recommends the use of HP PremierFlex OM4 and OM3+ fiber optic cables for 50 micron cable installations. HP PremierFlex OM3+ fiber optic cables provide higher bend performance and improved signal-transmission integrity, providing significant improvements in signal quality over industry-standard OM3 fiber optic cable technologies.
Fiber optic cable loss budgets Cable loss budgets are determined by the Fibre Channel Physical Interface Specification. See the standards at http://www.incits.org/. The maximum supported distances are based on modal bandwidth and type of fiber optic cable used. The different modal bandwidth and cable types that HP supports for Fibre Channel are: • 62.

1 Information for 62.5 micron fiber optic cable is provided to facilitate use of installed cable. HP recommends 50 micron fiber optic cable for new installations that require multi-mode fiber.

Interoperable, heterogeneous switch fabrics An interoperable, heterogeneous switch fabric can contain different series of switches. Table 75 (page 162) lists the switch combinations.
Additional factors such as distance, number of switch and device port buffers, and device response times can also affect performance. • Mixed Fibre Channel speeds For fabrics consisting of 16 Gb/s, 8 Gb/s, and 4 Gb/s; or 8 Gb/s, 4 Gb/s, and 2 Gb/s; or 4 Gb/s, 2 Gb/s, and 1 Gb/s switches and devices, the fabric segment connections negotiate the speed at which specific devices communicate.
