Abiquo Enterprise can manage multiple storage systems to provide users with virtual storage on demand. This section describes the configuration of compatible storage systems

Abiquo supports managed storage on iSCSI devices for storage technologies that were developed using the Storage Plugin SDK.

Abiquo also supports unmanaged storage on generic iSCSI devices.

This chapter will describe how to configure the external managed and unmanaged storage supported by the Abiquo Platformsupports hard disks on the hypervisor datastore. Hard disks are not persistent. When the user undeploys a VM with disks on the hypervisor datastore, these disks will be destroyed.

Abiquo detects datastore disk changes

Abiquo periodically checks hypervisors for changes in virtual machines, including CPU, RAM and datastore disks.  You can set an abiquo.property to control the frequency of these checks (abiquo.vsm.vmsyncfrequency.<PLUGIN> see Abiquo configuration properties#vsm). If a virtual machine datastore disk is resized, Abiquo updates the size registered in Abiquo. If Abiquo detects a change in the datastore used for the virtual machine primary disk, it updates the value in Abiquo and publishes the following tracer: 

• Datastore of virtual machine '{VIRTUAL_MACHINE_NAME}' has been changed from '{OLD_VALUE}' to '{NEW_VALUE}'.

Abiquo support for storage moves and motion is described in the tables for each hypervisor.
