The virtual storage machine is the unit that is used to manage virtualized resources for each storage system. For software with
global storage virtualization functions (for example,
global-active device,
nondisruptive migration), a virtual storage machine is created in the storage system.
For example, if
nondisruptive migration is used to migrate a storage system to
a
Virtual Storage Platform G200, G400, G600, G800 storage
system, the virtualized storage system is the migration source storage system. The migration source storage system is created in the migration target storage system. In
global-active device (GAD), the virtualized storage system is the storage system that contains the secondary volume (S-VOL) of the
GAD pair.
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.
For operations involving virtualized resources in a virtual storage machine, physical resources must be linked to virtualized resources. For example, when you perform operations on LDEVs in a virtual storage machine, you must specify physical LDEV IDs (not virtual LDEV IDs) that link to resources in a virtual storage machine.
For provisioning operations that involve virtualized resources in a virtual storage machine, you can perform provisioning operations that specify conventional physical resources or virtualized resources. However, provisioning operations that specify IDs of virtualized resources are limited.
For data management operations that involve virtualized resources in a virtual storage machine, you can perform data management operations that specify conventional physical resources or virtualized resources. However, data management operations that specify IDs of virtualized resources are limited.
You can edit the virtualization management settings of volumes to enable and disable virtualization management, set the virtual LDEV ID, and specify the virtual configuration (emulation type, CVS settings, and SSID).
