Atmosphere adds support for Dell PowerStore storage arrays.

Atmosphere currently deploys Ceph out of the box on dedicated white-box hardware to allow you to get distributed & highly available storage out of the box without any dedicated appliances.  However, one of the common things we’re seeing is Atmosphere users who want to make use of their existing infrastructure before migrating to something like Ceph.

Dell PowerStore arrays

Over the past few weeks, we’ve worked on adding the implementation of Dell PowerStore arrays to Atmosphere, this will allow you with a few simple modifications to have a fully tested and integrated solution that will leverage your existing storage array rather than deploy a new instance of Ceph.

We’ve done this by integrating a few things such as allowing for different CSIs for the Kubernetes cluster used for operating the cloud.  The default is using RBD, powered by Ceph.  It also allows you to switch to using the PowerStore CSI if you’re integrating with an existing array.

For Glance, we’ve instead switched up the integration to point towards storing images inside Cinder so that it can make use of the PowerStore array for storing all images.  Finally, Cinder is configured to use PowerStore to create volumes there using either fiber channel or iSCSI.

We’ve validated all of this internally and we’ll continue to support this system.  We’re happy to find ways to get our customers to be able to make use of their existing infrastructure to integrate into OpenStack and allow them to get the best experience to get bare metal, virtual machines & Kubernetes all in one simple solution.

For more information about how this works, check out the Atmosphere documentation that covers this topic specifically.

We’ve got a lot more updates on the way, so stay tuned and make sure to subscribe for more updates on news and feature updates.
