A technique for managing data storage for virtual machines in a data storage system includes receiving, from a virtual machine administrative program, a request to operate a virtual machine disk (VMD) at a different service level from one at which the data storage system is currently operating the VMD. In response to receiving the request, the data storage system migrates the VMD from a first set of storage extents providing a first service level to a second set of storage extents providing a second service level.

Managing data storage migration for virtual machines

Techniques are described for copying data. At a first storage processor, a copy request is received to copy data including copying source data from a source area of a source logical device to a destination area of a destination logical device. The source logical device is owned by the first storage processor and the destination logical device is owned by a second storage processor. The first storage processor receives, from the second storage processor, destination location physical storage mapping information for the destination area. A destination physical device location corresponding to the destination area is determined. The source data from the source area is stored in a first cache location of a first data cache of the first storage processor. The first cache location is modified to indicate it includes write pending data for the destination physical device location. The source data is destaged to the destination physical device location.

Optimizing copy processing between storage processors

Techniques are disclosed for monitoring the performance of transient virtual volumes created for a virtual machine. Each transient virtual volume is created in response to a first trigger event, used by the virtualization environment solely to perform a single function supporting execution of the virtual machine, and deleted in response to a second trigger event. When creation of a current transient virtual volume is detected, and while the virtualization environment uses the current transient virtual volume to perform a single function supporting execution of the virtual machine, performance data is collected for the current transient virtual volume, and combined with performance data collected for at least one other, previously deleted transient virtual volume that was used solely to perform the same single function supporting execution of the same virtual machine. The combined performance data is represented as performance data for a single monitored virtual volume associated with the virtual machine.

Monitoring performance of transient virtual volumes created for a virtual machine

Techniques for visualizing performance of file-based VVols and block-based VVols for aiding in administration of a data storage system operating in a virtualization environment allow performance of these different types of VVols to be visualized side-by-side using a common set of performance metrics. Thus, in one embodiment, the performances of file-based and block-based VVols are both converted into a mutually-compatible format and rendered for display together on screen.

Techniques for converging metrics for file- and block-based VVols

Techniques for visualizing performance of VVols for aiding in administration of a data storage system operating in a virtualization environment allow performance of these VVols to be visualized in a highly-flexible manner. Thus, in one embodiment, the performances of all VVols within a storage container are aggregated together for easy comparison among the aggregated performances of different storage containers.

Techniques for aggregating metrics for VVols within a storage container

A method, computer program product, and computing system for generating, by a computing device, a key, wherein the key includes at least one of an encryption key and an authentication key. One or more credentials may be generated to access a Secure KeyStore storing the key, wherein the one or more credentials may include one or more stable system values, and wherein the one or more stable system values may include one or more virtual values and one or more hardware values. The one or more stable system values may be provided to the Secure KeyStore to retrieve the key.
