Connection Configuration
This chapter explains the connection configuration of the ETERNUS DX.
SAN Connection
FC, iSCSI, FCoE, and SAS are available as host interfaces. The server and the ETERNUS DX can be
connected directly or via a switch.
Host Interface
This section describes each host interface.
The supported host interfaces vary between the ETERNUS DX100 S4/DX200 S4 and the ETERNUS
DX100 S3/DX200 S3. For details about host interfaces, refer to "Overview" of the currently used
storage systems.
When switches are used, zoning should be set for the switches to ensure the security of data.
