Abstract
First and second virtual storage controllers represent first and second physical storage controllers that provide access to different physical storage devices that back first and second virtual disks. One or more computing nodes host a virtual storage array that includes paired virtual storage directors. Each virtual storage director has access to both the first and second virtual storage controllers. Thus, the virtual disks may be presented to the storage directors as dual-ported disks even if the physical storage devices are single-ported. The virtual storage directors and virtual storage controllers may each be hosted by a separate virtual machine or instantiated in a separate container.
