• Direct and switch connections are supported. • Use target ports in the primary and secondary storage systems to connect with the host Fibre Channel ports. Initiator ports cannot be used for host connections. For more information about port attributes, see the topic on configuring host interface ports in the HP XP P9000 Continuous Access Synchronous User Guide. • The following table shows maximum, minimum, and recommended number of data paths, logical paths, and ports for ESAM.

If you do not, you will only be able to view ESAM information. • To perform any ESAM task, make sure RWC is in Modify Mode. For more information, see the HP XP P9000 Remote Web Console User Guide. External storage systems You can use HP storage systems, original equipment manufacturer (OEM) storage systems, and other vendors' storage systems (such as IBM or EMC) as connectable external storage systems. Hosts will recognize these volumes as internal volumes of the P9500 storage system. Remote Web Console requirements 15
