A method is used in managing virtual systems in data storage systems. First and second virtual systems are managed. The first virtual system uses a first format for communicating with a data storage system and the second virtual system uses a second format for communicating with the data storage system. A universal virtual system management module of the data storage system is used for communicating with the first and second virtual systems. The universal virtual system management module communicates with the first virtual system by using a first virtual system handler configured to communicate based on the first format. The universal virtual system management module communicates with the second virtual system by using a second virtual system handler configured to communicate based on the second format.

Managing virtual systems in data storage systems

A server device is configured to perform a method for providing object class information to a management device. The method includes mapping user names included as part of entries of a database associated with the server device to a corresponding Common Information Model (CIM) object manager operating system (OS) role. The method includes receiving a management request associated with the management device, the management request having management request credential information. The method includes authenticating the management request to an operating system associated with the server device based upon the management request credential information. The method includes following authentication, authorizing the management device to a corresponding CIM object manager OS role using the management request credential information. The method includes executing a CIM object call associated with the management request using the associated CIM object manager OS role to access object class information in response to the management request.

Credential authentication and authorization in a server device

In an analyzer device, a method for identifying a logical unit (LUN) of a data storage system as a candidate for migration to a second storage group is presented. The method includes receiving, by the analyzer device, a set of data associated with activity of the LUN of a first storage group, comparing, by the analyzer device, a performance metric value of a performance metric of the set of data, associated with the LUN, to a performance metric threshold associated with the performance metric, and when the performance metric value corresponds to the performance metric threshold, categorizing, by the analyzer device, the LUN as a candidate for storage on the second storage group, the second storage group distinct from the first storage group and having a disk type different from that of the first storage group.
