2. The request is switched (or routed) through the IP network with the destination IP address of an
iSCSI bridge or router.
3. The bridge or router converts the iSCSI request into its Fibre Channel equivalent.
4. The converted request is sent to the Fibre Channel target storage device.
The bridge or router performs the reverse conversion as the Fibre Channel target responds to the iSCSI
host. Conversion is transparent to both host and target since the iSCSI bridge or router mediates the
exchange at wire speed.
iSCSI boot
iSCSI allows initiators (IP hosts) to boot from an iSCSI target. An iSCSI HBA typically has boot
capabilities that must be enabled in its firmware.
iSCSI storage network requirements
HP recommends:
• Dedicated IP network for iSCSI storage (can be required for some iSCSI products)
• Minimum GbE network bandwidth
• Multipathing driver when implementing high availability
See the iSCSI product sections for additional requirements:
• MPX200 Multifunction Router with iSCSI , page 360
• EVA and EVA4400 iSCSI Connectivity Option , page 367
• HP StorageWorks Modular Smart Array 1510i , page 378
• B-series MP Router and iSCSI , page 382
• C-series iSCSI , page 384
MPX200 Multifunction Router with iSCSI
The EVA family of FC storage systems supports integrated iSCSI connectivity using the MPX200
Multifunction Router. The MPX200 hardware is integrated with up to four EVA storage systems and
HP Command View EVA 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 an EVA storage system or as a field upgrade to an existing
EVA storage system. With this product, iSCSI connectivity to the 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, data migration, and FCIP. The base functionality
is iSCSI, with the option to add either data migration or FCIP for standalone or concurrent operation.
This section describes iSCSI usage and support. For information about using the MPX200 data
migration feature, see “
MPX200 Multifunction Router with offline data migration ” on page 253. For
information about using the MPX200 FCIP feature, see the “ MPX200 Multifunction Router with
