iSCSI

The iSCSI remote data path can be set up in the following configurations:
•

Direct connection

• Local Area Network (LAN) switch connections
• Wide Area Network (WAN) connections
• WAN Optimization Controller (WOC) connections
Recommendations
The following is recommended for all supported configurations:
• Two paths should be configured from the host to the array. This
provides a backup path in the event of path failure.

remote arrays. Direct connections are used when the local and remote
arrays are set up at the same site. In this case, category 5e or 6 copper LAN
cable is recommended.
