Exemplary embodiments of the invention provide a technique to validate physical cabling and logical path before provisioning volume. In accordance with an aspect, a computer comprises a memory storing software and a processor executing the software. The software is operable to: identify first server port and second server port forming redundant ports of a server and first storage port and second storage port forming redundant ports of a storage system; and check whether a redundant relationship is formed by at least one of (i) a physical connection between the first server port and the first storage port and a physical connection between the second server port and the second storage port, or (ii) a logical connection between the first server port and the first storage port and a logical connection between the second server port and the second storage port.

Method and apparatus of redundant path validation before provisioning

Embodiments of the invention provide a capability to validate volume status on the host and storage system stored virtual machine image in the datacenter management server. In one embodiment, a server system includes a storage system having a plurality of volumes, a plurality of host systems, and a management server coupled with the storage system and the host systems via a network. A method of managing the server system comprises: generating a golden image in the storage system corresponding to a virtual machine image file; copying virtual machine data from the golden image to some of the plurality of volumes in the storage system; and keeping track, by the management server, of status of the volumes which have copied virtual machine data by monitoring activity of the virtual machines.

Method and apparatus of data center file system

A method selects an interface in a storage subsystem for processing storage operations, each interface associated with a corresponding processor. A management server has plural providers, each for executing storage operations on one of the processors via the corresponding interface. The method comprises: collecting information on status of each of the providers; based on the status of each provider, determining an operational characteristic of operation time as a function of a number of operational units for each provider; comparing the operational characteristics of the providers; for a given number of operational units in the storage operations to be processed, selecting from among the providers one provider which has the lowest operation time for the given number of operational units; and identifying the interface based on the selected provider to be used for executing the storage operations via the identified interface on the corresponding processor.
