Connection Configuration

This chapter explains the connection configuration of the ETERNUS AF.

SAN Connection

FC and iSCSI are available as host interfaces. The server and the ETERNUS AF can be connected directly or via a
switch.

Host Interface

This section describes each host interface.
The supported host interfaces vary between the ETERNUS AF250 S2 and the ETERNUS AF250. 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.
■
Fibre Channel (FC)
The FC connection topologies that are supported are Fibre Channel Arbitrated Loop (FC-AL) and Fabric. Direct
connections and switch connections to the servers are available.
The following types of host interfaces are available:
FC 32Gbit/s
•
This host interface is supported only for the ETERNUS AF250 S2.
FC 16Gbit/s
•
One of the following transfer rates can be specified:
For FC 32Gbit/s
•
32Gbit/s
-
16Gbit/s
-
8Gbit/s
-
For FC 16Gbit/s
•
16Gbit/s
-
8Gbit/s
-
4Gbit/s
-
■
iSCSI
Direct connections and switch connections to servers are available.
The following types of host interfaces are available:
iSCSI 10Gbit/s (10GBASE-SR/10GBASE-CR)
•
The transfer rate is fixed at 10Gbit/s.
10GBASE-CR is a form of communication that uses Twinax cables and is 10GBASE-SR-compliant.
iSCSI 10Gbit/s (10GBASE-T)
•
One of the following transfer rates can be specified:
10Gbit/s
-
1Gbit/s
