IBM TotalStorage SAN File System
The IBM TotalStorage SAN File System supports the DS6800. For more information on support, please refer to the following web

IBM System Storage Multi-path Subsystem Device Driver (SDD)
The SDD is designed to provide load balancing and enhanced data availability capability in configurations with more than one I/O
path between the host server and the DS6800 system. Load balancing can reduce or eliminate I/O bottlenecks that occur when
many I/O operations are directed to common devices via the same I/O path. SDD also helps eliminate a potential single point of
failure by automatically rerouting I/O operations when a path failure occurs, thereby supporting enhanced data availability
capability. The SDD is provided with the DS6000 series at no additional charge.
Refer to the individual server pages within this document for operating system level requirements and for DS6000 series LMC
prerequisites.
Refer to the IBM System Storage Multi-path Subsystem Device Driver User’s Guide for additional information.
Additional SDD information is also available at:

IBM System Storage DS Open Application Programming Interface (API)
The DS Open API supports routine LUN management activities, such as LUN creation, mapping, and masking, and the
management of point in time copy and remote mirroring. It supports these activities through the use of a standard interface as
defined by the Storage Networking Industry Association (SNIA) Storage Management Initiative Specification (SMI-S). It is
implemented through the IBM System Storage Common Information Model Agent (CIM Agent) for the DS6000 series, a
middleware application that provides a CIM-compliant interface. The DS Open API and CIM Agent are provided with the DS6800
at no additional charge.
•
The DS API coordinates with Microsoft Volume Shadow (VSS) Copy Service and the DS6000 series FlashCopy function
to create a consistent, point-in-time shadow copy of a Windows 2003 Server volume or group of volumes. This ensures
consistency for VSS aware applications.
•
The DS API also coordinates with Microsoft Virtual Disk Service (VDS). Microsoft VDS is a software interface that
manages block storage virtualization. This interface module makes it possible for the DS6000 series to interoperate with
applications that utilize the VDS Application Programming Interface in a Windows 2003 environment.
Refer to the individual server pages within this document for operating system level requirements and for DS6000 series LMC
prerequisites. While the CIM Agent is available for only selected operating system environments, it can be used to manage all
LUNs within a DS6000 series.
Refer to the IBM System Storage DS Open Application Programming Interface Reference for additional information.
IBM System Storage DS Command Line Interface (CLI)
The DS CLI is a single CLI that has the ability to perform a full set of commands for both configuration and copy services activities.
The DS CLI is provided with the DS6000 series at no additional charge.
Refer to the individual server pages within this document for operating system level requirements and for DS6000 series LMC
prerequisites. Refer to the
IBM System Storage DS Command-Line Interface User’s Guide for additional information.
IBM System Storage Continuous Availability
IBM System Storage Continuous Availability for Windows (formerly IBM TotalStorage Geographically Dispersed Clusters for
Microsoft Cluster Server) is designed to allow Microsoft Cluster installations to span geographically dispersed sites and help
protect clients from site disasters or storage subsystem failures. It is designed to enable a tier 7 disaster recovery solution and
provide high availability for applications and data running in Windows clustered server environments by extending the distance that
cluster nodes and storage can be separated, mirroring data between DS6000 series systems. Support for IBM System Storage
Continuous Availability is available via an IBM services contract to implement and customize the solution for your environment.
