ETERNUS DX80 S2/DX90 S2 Disk storage system OverviewCopyright 2013 FUJITSU LIMITED P3AM-4812-11ENZ029Chapter 3Connection ConfigurationsThis chapter explains the possible connections for ETERNUS DX Disk storage system operation.Figure 3.1 Connection configuration3.1 Host Connections (SAN)Storage Area Network (SAN) is a dedicated network to connect ETERNUS DX Disk storage systems to servers(hosts).FC, iSCSI, FCoE, and SAS are available as host interfaces. Depending on the connection configuration, thedestination can be a server HBA or a switch.Using driver software for multipath control enables reliable and high performance connection configurationsby controlling the server and the ETERNUS DX Disk storage system with multiple paths.This section describes each host interface.Administration terminalManagement/MonitoringserverLANLAN for operation managementRemote supportcenterCACARASAN/WANfor remote copyStorage Area Network (SAN)Server (Host)ETERNUSDX Disk storagesystemSwitchHost interfaceThis is an interface that is used to connect to the server HBA or switch.Remote interfaceThis is an interface that is used for remote copy.This is used to connect a terminal for monitoring operations and device settings.This is also used to connect to the remote support center using the remote support function.CA:RA:LAN:PWCPower synchronized unitPower controlUninterruptiblePower Supply (UPS)ETERNUSDX Disk storagesystemPWC portThis is used to enable the ETERNUS DX Disk storage system to be powered on and off with servers.PWC:
