MPX200 Multifunction Router with iSCSI for P6000/EVA storage
The P6000/EVA family of FC storage systems supports integrated iSCSI connectivity using the
MPX200 Multifunction Router. The MPX200 hardware is integrated with up to four P6000/EVA,
3PAR (see “MPX200 Multifunction Router with iSCSI for 3PAR StoreServ Storage” (page 339)), or
XP 24000/20000 storage systems (see “MPX200 Multifunction Router with iSCSI for XP storage”
(page 342)), and HP P6000 Command View to deliver multiprotocol capabilities. This provides
iSCSI and FC attached servers access to block storage through an FC and Ethernet IP network
simultaneously. The MPX200 is available from HP factory-integrated with a P6000/EVA storage
system or as a field upgrade to an existing P6000/EVA storage system. With this product, iSCSI
connectivity to the P6000/EVA is provided for servers through a standard 1-GbE or 10-GbE NIC.
The MPX200 chassis contains one or two router blades, two PCMs, and a midplane. There are
two types of router blades: a 4-port 1-GbE blade and a 2-port 10-GbE/2-port 1-GbE blade. Both
blade options include two 8-Gb/s FC ports. MPX200 dual-blade configurations provide for high
availability with failover between the blades.
MPX200 simultaneous operation
The MPX200 Multifunction Router supports iSCSI, FCoE, data migration, and FCIP. The base
functionality is iSCSI/FCoE, with the option to add one other license-enabled function—either data
migration or FCIP for standalone or concurrent operation. This section describes iSCSI usage and
support. For information about using the MPX200 FCoE feature, see “Fibre Channel over Ethernet”
(page 62). For information about using the MPX200 data migration feature, see “MPX200
Multifunction Router with data migration” (page 226). For information about using the MPX200
FCIP feature, see “MPX200 Multifunction Router with FCIP” (page 282). For information about
configuring the MPX200 for multiple functions concurrently, see the HP MPX200 Multifunction
Router User Guide.
MPX200 configuration options
A P6000/EVA storage system can be configured for simultaneous connectivity to iSCSI and FC
attached hosts. Support for iSCSI to a P6000/EVA storage system is provided through the MPX200
and an existing FC switch fabric port (fabric-attached) or direct-connect to an EVA controller port.
Figure 134 (page 333) shows an MPX200-EVA single-blade fabric-attached configuration. This is
the lowest-cost configuration and is used when high availability for iSCSI hosts is not required.
