MPX200 Multifunction Router
User Guide
This user guide describes the MPX200 Multifunction Router, which supports the EVA family of Fibre Channel
storage systems for integrated iSCSI connectivity, FCIP, and data migration. The MPX200 hardware is integrated
with up to four EVA storage systems and HP Command View EVA to deliver multi-protocol capabilities, including
Fibre Channel, iSCSI, and FCIP. This document is intended for system administrators with knowledge of HP
StorageWorks EVA4x00/6x00/8x00 storage systems, configuring LUNs using HP Command View EVA, HP
Fibre Channel SANs, Ethernet, TCP/IP networking, iSCSI, and FCIP.

1 MPX200 Multifunction Router overview
MPX200 features
The Enterprise Virtual Array (EVA) family of Fibre Channel (FC) storage systems is supported for
integrated iSCSI connectivity using the MPX200. The MPX200 hardware is integrated with up to four
EVA storage systems, for iSCSI connectivity, to deliver multi-protocol capabilities. This provides iSCSI
and FC attached servers access to block storage through an FC network and an Ethernet IP network
simultaneously. Also, FCIP and data migration capabilities are available for use.
The MPX200 is available from HP factory-integrated with an EVA storage system or as a field upgrade
to an existing EVA storage system. iSCSI connectivity to the EVA is provided for servers through a
standard 1-Gigabit Ethernet (GbE) or 10-GbE network interface controller (NIC).
The MPX200 chassis contains one or two router blades, two power and control modules (PCMs), and
a mid-plane. 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 blades.
NOTE:
Each PCM has three variable-speed fans that provide power and cooling. You can remove and replace
a PCM at any time. To ensure that the MPX200 chassis remains operational, there must be at least
one functioning PCM. Each PCM is capable of powering two blades. The PCM cools the corresponding
blade; therefore, when you remove a PCM, you must replace it within 7 minutes or the blade will shut
down due to an over-temperature condition.
Table 1 lists the MPX200 part numbers and describes each option.

MPX200 configuration options
You can configure an EVA storage system for simultaneous connectivity to iSCSI and FC attached
hosts. Support for iSCSI to an EVA is provided through the MPX200 and an FC switch fabric port
(fabric attach) or the MPX200 directly connected to the EVA.
NOTE:
Directly connecting an MPX200 FC port and an EVA requires the EVA controller port to be set to
Direct.
Figure 1 illustrates an MPX200 single-blade fabric-attached configuration. This is the lowest-cost
configuration and is used when high availability for iSCSI hosts is not required.

high availability with failover between blades.
NOTE:
A dual-blade configuration may require reconfiguration of device mappings.

Planning the MPX200 installation
Before installing the MPX200, it is important to define the requirements for iSCSI server connectivity
and MPX200 multi-function usage. You should consider present and future needs as they relate to the
following MPX200 configuration attributes:
• Simultaneous operation
You can configure the MPX200 chassis with a single blade or dual blades to run up to two operations simultaneously per blade as shown in Table 2 on page 27.
• iSCSI operation
• Dual-blade configurations are for high availability
• Total number of initiators
• Number of paths required per initiator
• Use of Internet Storage Name Service (iSNS)
• Use of iSCSI ports
• Load balancing
• 10-GbE initiators
Table 3 describes the MPX200 supported configuration maximums for ports, blades, and chassis.

Total number of initiators
You can configure the MPX200 with a single blade or with two (redundant) blades. When using two
blades, the initiator is registered in both blades for consistency, whether or not you intend to access
both blades.

Number of paths required per initiator
After establishing the number of initiators, determine how many paths are required by each. The
number of connections per blade is finite, and every initiator login constitutes a connection to the
MPX200. In a multipath environment, HP recommends a minimum of one connection per blade;
high-performance applications may require up to four connections per blade (a total of eight).
Use of iSNS
The MPX200 presents one iSCSI target for each virtual port group (VPG) (a total of four). Each initiator,
therefore, discovers four times the number of FC targets. HP recommends that you use iSNS to present
to the initiator only the required iSCSI targets.
Use of iSCSI ports
When configuring the MPX200 for iSCSI, there are four available iSCSI ports per blade. For high
performance and maximum initiator connectivity, HP recommends that you use all available ports.
Balancing the load
HP recommends that you use all iSCSI ports for both 1-GbE and 10-GbE blades. If multiple 1-GbE
initiators are required, ensure that logins are spread across all 1-GbE ports. For 10-GbE blades, you
can place a higher number of initiators on the 10-GbE ports than on the 1-GbE ports.
MPX200 Multifunction Router overview28
Because iSCSI and data migration traffic can share the same FC ports, it is prudent to understand
how each function effects the other during I/O operation. The use of bandwidth throttling for data
migration or MPIO to control the amount and path I/O follows.
10-GbE initiators
HP recommends that you map servers with 10-GbE NICs for login to the 10-GbE ports on the MPX200.
CHAP security
You can configure the Challenge Handshake Authentication Protocol (CHAP) on the MPX200. CHAP
is a security protocol that supports the bi-directional (mutual) authentication option and the one-way
(target) authentication option. The target MPX200 can have a unique password for the one-way CHAP
option. The initiator can have a unique password for the bi-directional CHAP option with the target
MPX200.
