Preface

The SHC-OSD software product is the BS2000 host component for storage systems. It makes storage management functions available to the BS2000 operating system. It connects storage systems and their administration with the BS2000 operating system.

SHC-OSD supports the ETERNUS DX/AF storage systems of FUJITSU, as well as the Symmetrix® and EMC VMAX3/VMAX AFA™ of EMC Corporation.

SHC-OSD implements information services and control commands for local and remote replication functions of the storage systems. The replication functions are offered with functions of the storage systems:

• Equivalent Copy (EC), QuickOPC, SnapOPC+ and Remote Equivalent Copy (REC) for ETERNUS DX/AF

• TimeFinder and SRDF™ for Symmetrix

• TimeFinder SnapVX™ and SRDF™ for VMAX3/VMAX AFA

In detail SHC-OSD offers the following functions:

• Information on the configuration of the storage system

  • output of global configuration data, such as model and firmware version, number of physical and logical devices, cache size, storage cluster

  • output of information on the logical devices of the storage system, such as device name, capacity, RAID level

• General functions for local replication

  • output of status information

  • set up and cancel local replication

  • splitting of original data and copy for independent processing of data

  • reconstruction of data

• Functions for local replication with ETERNUS DX/AF

  • QuickOPC: immediately available, complete copy of the data

  • Equivalent Copy (EC):
    quickly available, complete copy and mirroring of the data

  • SnapOPC+: directly available “snapshot” of the data.

• Functions for local replication with TimeFinder™ for Symmetrix/VMAX3

  • TimeFinder/Clone: immediately available copy of the data

  • TimeFinder/Snap for Symmetrix and TimeFinder SnapVX for VMAX3: directly available "snapshot" of the data

• General functions for remote replication

  • output of status information

  • set up and cancel remote replication

  • change the processing mode

  • testing the recovery procedures

  • control after a disaster

• Functions for remote replication with ETERNUS DX/AF

  • Remote Equivalent Copy (REC): synchronous and asynchronous replication between ETERNUS DX/AF storage systems

• Functions for remote replication with Symmetrix/VMAX3 (SRDF, Symmetrix Remote Data Facility)

  • SRDF/S: synchronous replication between Symmetrix/VMAX3 storage systems

  • SRDF/A: asynchronous consistent replication between Symmetrix/VMAX3 storage systems

• Thin/virtual provisioning for ETERNUS DX/AF and Symmetrix/VMAX3

  • output of configuration and status information

  • monitoring functions

• Automated Storage Tiering (AST) for ETERNUS DX/AF

  • output of configuration and status information

  • monitoring functions

• Storage Cluster Option (SCO) for ETERNUS DX/AF

  • output of configuration and status information of the Storage Cluster

  • monitoring functions

  • manual failover and failback

The settings required to use these functions in the storage systems are configured up front by a qualified technician. The necessary software and licenses must exist.

The prerequisites for the use of SHC-OSD and for the supported storage systems are described in the section "Installing and configuring SHC-OSD".

Integration of ETERNUS DX/AF in SHC-OSD is based on the component StorMan from FUJITSU. StorMan integrates storage systems based on the SNIA standard SMI-S. For ETERNUS DX/AF the SMI-S Provider of FUJITSU is used for this purpose.

Integration of Symmetrix/VMAX3 storage systems in SHC-OSD and is based on SYMAPI (Symmetrix Application Programming Interface), the strategic interface of EMC Corporation for controlling the storage systems. This interface is used in the context of the partnership between FUJITSU and EMC Corporation.
