NEC Storage Virtual Volume allows the disk array of NEC Storage M series to work together with VMware vSphere for managing disks of virtual machines (virtual disks) running on ESXi hosts of vSphere so that disk array functions can be configured and operated on a virtual machine basis.
In vSphere environments so far, an LUN contains multiple virtual machines. Therefore, as the I/O flow control function NEC Storage M series has, for example, runs on an LUN basis, VM-based I/O flow control is not possible. Installing NEC Storage Virtual Volume, however, makes the virtual disks be managed by storage as virtual volumes (VVOLs). Accordingly, I/O flows can be controlled on a virtual machine basis by the I/O flow control function of NEC Storage M series.
