Enabling simultaneous shared access to guaranteed-performance volumes

CloudStack's storage infrastructure does not currently allow for multiple VMs to attach to the same data disk simultaneously.

Interoute, however, has a critical use case whereby there is a necessity to allow multiple VMs to perform such an action.

In this situation, we were constrained to using an existing version of CloudStack (4.5), so no code changes to the "core" software could be made.

We decided on an approach that leveraged CloudStack's extensive plug-in framework.

Using CloudStack's ability to support plug-ins, we developed three plug-ins to solve the problem:

1) A plug-in that extended CloudStack's API to support additional functionality.

2) A GUI plug-in for root admins to set up storage and VLANs.

3) A second GUI plug-in (typically used for standard users) to create volumes that can be directly accessed via the OSes running in the applicable VMs.
