EVA and EVA4400 iSCSI connectivity options
An EVA storage system can be configured for simultaneous connectivity to iSCSI and Fibre Channel
attached hosts. Support for iSCSI is provided through a d e d icated EVA host port (direct connect) or
shared with Fibre Channel through an existing fabric host port (fabric attach).
Figure 1 illustrates the direct connect iSCSI–Fibre Channel a ttachment mode configuration. This
configuration is used with an EVA 4000/4100/6x00/8x00 storage system. Figure 2 illustrates the direct
connect iSCSI-Fibre Channel attachment mode for an EVA4400 storage system.

setup. CHAP is a security protocol that includes support for both the bidirectional (mutual) authentication
and the one-way (target) authentication options. You can configure and set up CHAP in the
mpx100/100b. Thetargetmpx100/100bcanhaveitsownuniquepasswordforOne-WayCHAP
option. The initiator itself can have its unique password for the bidirectional CHAP o ption with the

Configuring HP StorageWorks Continuous Access EVA and
Business Copy
Currently supported EVA software applications for Fibre Channel hosts such as HP StorageWorks
Continuous Access, Business Copy (BC), Storage System Scripting Utility (SSSU), and Replication
Solutions M anager (RSM) are supported with the EVA iSCSI connectivity option. The limitations of using
some of these applications on iSCSI hosts are discussed in Chapter 2, page 29.

General EVA and EVA4400 iSCSI connectivity rules
NOTE:
The EVA iSCSI c
onnectivity option (mpx100) is supported with EVA4000/4100/4400/6x00/8x00 and
EVA3000/5000 storage systems. The E VA4400 iSCSI connectivity option (mpx100b) is supported
only with EVA4400 storage systems.
• Each EVA storage system can h ave a maximum of two mpx100 or two mpx10 0b bridges.
• Each EVA controller host por t can connect to a maximum of two mpx100/100b FC por ts.
• B oth mpx10 0/100b FC ports can connect only to the same EVA storage system.
• Each mpx100/100b FC port can connect to a maximum of one EVA port.
• Each iSCSI Initiator can have a maximum of eight mpx100/100b iSCSI targets.
