							About Hitachi Command SuiteHitachi Command Suite consists of a number of storage managementsoftware products used for managing storage resources in large-scale,
complex SAN environments.
HCS includes:
• Hitachi Device Manager:  Supports registration of physical resources to
be managed, including storage systems, file-servers, hosts, and related tasks such as volume allocation and grouping of resources for easier
management and access.
• Hitachi Tiered Storage Manager:  Supports storage tiers of differing
performance characteristics so that volume data storage costs and
performance can be optimized.
• Hitachi Replication Manager:  Supports volume data replication for
backup and disaster recovery.
• Hitachi Tuning Manager:  Supports optimizing the performance of
storage resources.
• Hitachi Compute Systems Manager:  Supports centralized monitoring
and management of hosts, including rebooting and power management.
• Hitachi Command Director:  Supports sophisticated business centric
views of storage environments, such as adherence to service level agreements and data usage trends to forecast future storagerequirements.

between resources such as hosts and storage for path fail-over and load
balancing.
• Hitachi Global Link Manager:  Supports management of multi-path
management software between resources, such as hosts and storage.
Each product must be licensed for use in HCS. At minimum, you must license
Device Manager. Additional licensing can be added as needed for other
storage management products. Related functionality becomes available in the
HCS user interface in the form of activated menu choices, and new or updated tabs and related screens and buttons.
For Hitachi Virtual Storage Platform G1000, additional functionality for configuring the storage system is available from launch points in HCS to
Hitachi Device Manager - Storage Navigator. Use the right-click menu from the list of storage systems on the Resources tab, or click the System GUI link
on the application pane to access the additional functionality.
Instances of the management software products above can be installed on one or more HCS servers depending on the scale of resources under
management and geographic location. For information about supported HCS server operating systems and other system requirements, see  Hitachi
