The '''R215F Expander''' provides additional mass storage capacity for [[MicroVAX]] systems that have a [[DSSI]] bus.

Up to three [[RF-series]] Integrated Storage Elements (ISEs) can be included in the expander. 
An ISE is an intelligent storage device that contains its own controller.

* [[RF31]]
* [[RF31F]]
* [[RF31T]]
* [[RF35]]
* [[RF36]]
* [[RF72]]
* [[RF73]]

The R215F enclosure is a [[BA215]] enclosure with the [[card cage]] removed, and an additional mass storage bay in its place. It has three mass storage bays:

* Two bays in the top of the cabinet
* One bay in the middle of the cabinet

Each mass storage bay can hold one ISE.
