One of the more exciting announcements at VMworld 2018 was a preview of VMware vSAN utilizing Amazon Elastic Block Store (Amazon EBS) with VMware Cloud on AWS.  This service is called Elastic vSAN and is soon available. Elastic vSAN runs on new Amazon EC2 R5.metal instances to augment existing SDDC for storage-dense environments. Storage per host ranges from 15 to 35 TB in increments of 5 TB. The user chooses the amount of storage desired and used on all hosts within the cluster. R5.metal clusters can also be added to an existing SDDC with at least one existing provisioned cluster.

This week on the Virtually Speaking Podcast we welcome VMware’s Glenn Sizemore to walk us through the details of this new service. Elastic vSAN has effectively solved the data gravity challenge inside VMware Cloud on AWS. More importantly, it provides an architecture to deliver future capabilities via software; composing the underlying hardware as required based on current capabilities.
