An object in a tier of a multi-tier virtual storage system is saved while the storage system is active. The object to be saved in an upper-level tier in the multi-tier storage system is identified. Servers associated with lower-level tiers below the tier containing the object to be saved to obtain the latest data stored in the respective associated tiers, use temporary storage to store the obtained data and handle any modifications to the obtained data, and cause applications running in the respective tiers to quiesce. Once a copy of the identified object is made, the servers associated with the lower-level tiers are instructed to obtain the data from the temporary storage and resume quiesced applications running in the respective tiers.

Method, computer program product, and system for providing a multi-tiered snapshot of virtual disks

A method for adding storage space to a server without powering down the server is provided. One embodiment provides a method for dynamically linking a storage space to a network server, comprising: adding a new disk drive image to a network server description for the network server through a host server operating system, the new disk drive image corresponding to the storage space to be linked; sending a dynamic linking request from the host server operating system to a network server operating system; in response to the dynamic linking request, sending a device scanning request from the network server operating system to the host operating system; in response to the device scanning request, requesting response from each device connected to each SCSI port of a host server and reporting the new disk drive image to the network server operating system; and presenting the new disk drive image to users connected to the network server.
