  • Page 17: Power Supply Units

    A System Capacitor Unit (SCU) is installed in a controller as a backup power source in case of power outage. The SCU is charged from an external power source while the ETERNUS DX Disk storage sys- tem is running normally. If a power failure is detected, data in the cache memory is saved to the non-volatile memory in the controller using the SCU.

  • Page 44: Chapter 3 Connections

    This chapter explains connections for the ETERNUS DX Disk storage system. Host Connections FC, iSCSI, FCoE, and SAS are available as host interfaces. The server and the ETERNUS DX Disk storage system can be connected directly or via a switch.

  • Page 45: Host Connection Path

    ■ FCoE Fabric is supported as a connection topology. The maximum transfer speed is 10Gbit/s. When using an FCoE interface, connect the ETERNUS DX Disk storage system to the FCoE switch. Direct connections to servers are not supported. • VLAN The VLAN function is supported.

  • Page 46: Figure 3.1 Single Path Connection (Direct Connection)

    3.1 Host Connections ■ Single path configuration A single path configuration connects the ETERNUS DX Disk storage system to a server via a single path. The server cannot access an ETERNUS DX Disk storage system when a component (such as a controller, HBA, switch, or cable) on the path has a problem.

  • Page 47: Figure 3.3 Multipath Connection (Direct Connection)

    • Paths from a single server should be separately connected to a different host interface adapter in case of host interface adapter failure. ETERNUS DX80 S2/DX90 S2 Disk storage system User’s Guide -Site Planning- Copyright 2011 FUJITSU LIMITED P3AM-4822-03ENZ0...

    Configurations that satisfy the system requirements System requirements should be taken into consideration for a connection configuration between the HBAs on the server and the host interface ports on the ETERNUS DX Disk storage system. The following figure shows a connection configuration for availability:...

  • Page 49: Remote Connections

    For remote connections, different types of interfaces (FC, iSCSI 1Gbit/s, iSCSI 10Gbit/s) cannot exist together on a REC path (connection between a local ETERNUS DX Disk storage system and a remote ETERNUS DX Disk storage system). When different types of remote interfaces exist in the same ETERNUS DX Disk storage system, make sure to use the same type of interface for each REC path.

  • Page 50: Remote Interfaces

    Data is transferred between multiple ETERNUS DX Disk storage systems by using remote inter- face adapters (FC-RA). The ETERNUS DX Disk storage system can be connected to the desti- nation storage system directly or via switch. A digital service unit is required for a remote connection that is using a line.
