Managing virtual storage machine resources

Virtual storage machines are used to achieve continuous access to data for global-active device volumes and for data migration.

• Provisioning

  The advanced provisioning software products and features of the storage systems enable you to implement the appropriate provisioning strategies for your operational environment and improve performance and capacity utilization. Dynamic Provisioning allows you to reserve virtual storage capacity based on anticipated future capacity needs using virtual volumes instead of physical disk capacity, providing lower initial cost, greater efficiency, and ease of storage management.

• Using virtual storage machines for nondisruptive migration

  The nondisruptive migration (NDM) software is used to migrate data nondisruptively from a source storage system to a target storage system. When NDM is used, the program product configuration data is also migrated to enable business operations to continue without interruption.

• Using virtual storage machines for global-active device

  Global-active device (GAD) enables you to create and maintain synchronous, remote copies of data volumes. Both volumes of a GAD pair can receive the same data from the server.

• Enabling the virtualization management setting for LDEVs

  Use this procedure to enable the virtualization management setting of volumes using Device Manager - Storage Navigator. When virtualization management is enabled for a volume, you can set the virtual LDEV ID and specify the virtual volume configuration of the volume.
