1 HP FlexFabric 5900CP switch overview

The HP FlexFabric 5900CP switch is a ToR (Top of Rack) converged L2/L3 switch with 48 converged

ports and four 40GbE QSFP ports. This switch provides seamless integration of 10GbE networks

into existing server-edge environments, such as FCoE DCB and Fibre Channel. It is a full featured

switch and a software license is not required. When coupled with the HP StoreFabric converged

optical transceiver, it provides wire-once capability for 10GbE/FCoE and 8 Gb or 4 Gb Fibre

Channel.

Figure 1 HP FlexFabric 5900CP front (port) and rear (power) view

The switch is supported as a standard Ethernet switch in HPN Ethernet networks and as a DCB

Ethernet switch for converged environments with Ethernet/FCoE. It provides native Fibre Channel

connectivity and can be used as a gateway to other HP Fibre Channel switch series fabrics using

NPV.

It can be added in an HP 5900 series IRF (Intelligent Resilient Framework) to simplify management

by combining multiple physical switches into one virtual switch. An IRF fabric appears as one node

or virtual switch and is accessible as a single IP address on the network. You can use this IP address

to log in at any member device to manage all the members of the IRF fabric.

Figure 2 (page 5) describes the major components and the ports of the HP FlexFabric 5900CP

switch. The front view shows 48 converged ports, which can be configured as 1 or 10GbE, or 8,

4 or 2 Gb Fibre Channel. The four 40GbE ports can be configured as four individual 40GbE

ports, or 16 10GbE ports when used with a splitter cable.

The switch supports two pluggable fan trays and two AC power supplies for redundancy. Two

options are available for fan trays, front-to-back airflow or back-to-front airflow.

HP FlexFabric 5900CP network architectures

The HP FlexFabric 5900CP switch can be utilized in the following environments:

•A traditional Ethernet network for Ethernet data

•A converged network switch in environments that support Ethernet and FCoE for Ethernet and

storage data

•A native Fibre Channel fabric switch for storage data

In a converged environment, the HP FlexFabric 5900CP switch is configured as a ToR switch

connecting to a LAN and a SAN.

LAN connectivity is made through any of the 48 converged ports configured as 10GbE ports or

the 40GbE ports for a total of up to 64 10GbE ports.

SAN connectivity is made through any of the 48 converged ports configured as 10GbE/FCoE

ports or configured as 8/4/2 Gb Fibre Channel ports. When configured as Fibre Channel ports,

the converged ports support device connectivity (F_Port) or switch connectivity via NPV (NP_Ports)

to other HP Fibre Channel switches that support NPIV.

2 Port types and switch modes

To support LAN and SAN environments, the HP FlexFabric 5900CP switch utilizes multiple port

types and switch modes.

Port types

The HP FlexFabric 5900CP switch supports multiple port types. Table 1 (page 6) lists the port

types supported.

Table 1 Supported HP FlexFabric 5900CP port types

Ethernet Port Types

•Access/Tagged-trunk 10GbE/40GbE ports used for Ethernet data

FCoE Port Types

•VF_Port: Virtual F_Port (FCoE switch to FCoE target/initiator)

•VE_Port: Virtual E_Port (FCoE switch to FCoE switch) (future use-case support)

•VNP_Port: FCoE NPV switch port (FCoE switch to FCoE switch as a proxy)

FC Port Types

•F_Port: Fabric port (switch to FC target/initiator)

•E_Port: Expansion port (switch to switch ISL) (future use-case support)

•NP_Port: NPV switch port (FC switch to FC switch as a proxy)

Switch modes

The HP FlexFabric 5900CP switch supports four operating modes. Standard mode is the default

mode. FCF, NPV, and Transit modes are advanced modes.

1. Standard (Non-FCoE) Mode—When a switch operates in this mode, it is a standard/DCB

Ethernet switch and does not provide any FCoE/FC capabilities.

2. FCF (Fibre Channel Forwarder)—When a switch operates in this mode, it is called as an FCF

switch. In this mode, the following HP FlexFabric 5900CP converged port connections are

available:

Fibre Channel

•HP FlexFabric 5900CP F_Port to an N_Port on a node.

•HP FlexFabric 5900CP (NPIV) F_Port to an NP_Port on an NPV switch.

•HP FlexFabric 5900CP E_Port to an E_Port on another HP FlexFabric 5900CP FCF switch.

FCoE

•HP FlexFabric 5900CP VF_Port to a VN_Port on a node.

•HP FlexFabric 5900CP (NPIV) VF_Port to a VNP_Port on an NPV switch.

•HP FlexFabric 5900CP VE_Port to the VE_Port on another HP FlexFabric 5900CP FCF

switch.

If the primary mode of the HP FlexFabric 5900CP switch is set to FCF, the converged ports

can be set to F_Port or E_Port, but cannot be set to NP_Port. For FCoE, the ports can be set

to VF_Port or VE_Port, but cannot be set to VNP_Port.

NOTE: At present, no E_Port connectivity use-cases are supported.

6 Port types and switch modes

3. NPV/Gateway Mode—When a switch operates in this mode, it is called as an NPV (N_Port

Virtualizer) switch. In this mode, the following HP FlexFabric 5900CP converged port

connections are available:

Fibre Channel

•HP FlexFabric 5900CP F_Port to an N_Port on a node.

•HP FlexFabric 5900CP NP_Port to an F_Port on an FCF (NPIV) switch.

FCoE

•HP FlexFabric 5900CP VF_Port to a VN_Port on a node.

•HP FlexFabric 5900CP VNP_Port to a VF_Port on an FCF (NPIV) switch.

If the primary mode of the HP FlexFabric 5900CP switch is set to NPV, the converged ports

can be set to F_Port or NP_Port, but cannot be set to E_Port. For FCoE, the ports can be set

to VF_Port or VNP_Port, but cannot be set to VE_Port.

4. Transit Mode—When a switch operates in this mode, it is called as a Transit switch. A switch

operating in this mode can restrict its Ethernet interface only to receiving traffic from an eNode

or FCF switch. This is achieved by configuring the interface to operate in eNode mode or FCF

mode. Fibre Channel is not supported in this mode. When a switch is configured in Transit

mode, it always enables FIP snooping. VF_Port traffic is allowed. However, VE_Port traffic is

blocked.

NOTE: After changing to any one of the advanced modes and saving the configuration,

you must reboot the switch.

3 Storage use-cases

The HP FlexFabric 5900CP switch supports several converged Ethernet/FCoE and Fibre Channel

storage configurations. To simplify understanding and implementation of these configurations, a

set of use-case topology designs are defined. The use-cases describe recommended ways to use

the HP FlexFabric 5900CP switch, switch modes, and port types in different server-storage

deployment scenarios. Some of the use-cases show multiple types of connectivity within the same

configuration. This is meant to show the different connection options available. Your design might

use one or more of these options, but not necessarily all as shown.

HP recommends that all storage configurations implement dual-redundant fabrics for high availability.

All HP FlexFabric 5900CP switch use-cases for storage described here implement dual-redundant

fabrics for high availability.

NOTE: The IRF feature of the HP FlexFabric 5900CP switch can be implemented in dual-redundant

fabric designs with storage, but has implications that must be considered. For more information

about using IRF in a storage configuration, see “IRF usage with storage” (page 14)

Figure 3 (page 8) provides three major use-case scenarios, each describing a different

implementation based on the hardware being utilized for servers and storage. All use-cases show

a single layer or single tier of HP FlexFabric 5900CP switches, also referred as East-West fabric

topology, with variations for use-case 2 and use-case 3. Use-case 2 shows dual-hop on the server

side and use-case 3 shows additional fabric connectivity on the storage side to other HP Fibre

Channel/FCoE switch series fabrics via 5900CP NPV gateway mode.

Figure 3 HP FlexFabric 5900CP major use-case scenarios

Table 2 (page 9) describes the HP FlexFabric 5900CP use-cases in detail. The items listed in the

variant column are links to the figures which describe the variant connectivity options in detail.
