The 'quorum disk' is just a little Java program. This can run on any cloud service provider as well, such as IBM SoftLayer, that both buildings have connectivity.Ī minor improvement worth mentioning is that the IBM 'Comprestimator' tool that estimates the capacity savings of Real-time Compression is now integrated into Spectrum Virtualize v7.6 command line interface (CLI), allowing you to run the tool on demand, as needed, on any virtual volume. IBM plans to offer all of its solutions in any of three flavors: software-only that you can deploy on your own server hardware, pre-built system appliances, and cloud services on IBM SoftLayer, IBM Cloud Managed Services or third-party cloud providers.

Spectrum Scale is the software-only flavor, and Elastic Storage Server and Storwize V7000 Unified are pre-built systems based on that software. IBM published a 'Redbook' on how to implement OpenStack Swift and Amazon S3 interfaces to an existing Spectrum Scale deployment.

IBM supported it, but it was basically Do-it-Yourself DIY implementation. This has now been resolved, with full integration of OpenStack Swift and Amazon S3 object-protocol interfaces. (For those unfamiliar with 'Object storage', think of it like valet parking for your data.
