Overview

ScaleIO is a software-only solution that uses existing servers' local
Dell EMC VxFlex OS (formerly named Dell EMC ScaleIO) is a software-only
solution that uses existing servers local
disks and LAN to create a virtual SAN that has all of the benefits of
external storage, but at a fraction of the cost and complexity. Using the
driver, Block Storage hosts can connect to a ScaleIO Storage
driver, Block Storage hosts can connect to a VxFlex OS Storage
cluster.

The Dell EMC VxFlex OS Cinder driver is designed and tested to work with
both VxFlex OS and with ScaleIO. The
:ref:`configuration options <cg_configuration_options_emc>`
are identical for both VxFlex OS and ScaleIO.

Dell EMC ScaleIO has been renamed to Dell EMC VxFlex OS.
Documentation for the driver can be found under the new name.
The driver maintains full backwards compatability with prior
ScaleIO releases and no configuration changes are needed upon
upgrade to the new version of the driver.
