VMware Cloud on AWS vSAN

Elastic vSAN Scale-Up Storage

The march of progress continues within the VMware Cloud on AWS service. With the 1.8 release introducing the ability to dynamically scale-up storage capacity with any Elastic vSAN SDDCs. This new capability further empowers customers to right-size their SDDC by leaning into the elasticity of the AWS cloud.

How does it work?

When a cluster begins to fill up, customers can add capacity by adding additional hosts to the cluster. Or they can choose to add storage to the existing hosts (up to the maximum per host). This change is processed on every host in the cluster and is available on the VMware Cloud on AWS SDDC Console and service API.

Dynamic Scale-Up empowers a customer to start small and incrementally scale-up storage capacity on demand. Thereby controlling costs by right-sizing the SDDC to the needs of the workload. Once the per-host capacity is maxed out, further capacity increases require adding one or more hosts.

Elastic vSAN

Scaling down is still based on host removal. Elastic DRS still uses host addition/removal to right-size the cluster based on utilization.

Expanded Availability

Just in time to take advantage of this powerful capability, the service announced expanded availability for the r5.metal instance and Elastic vSAN as of this writing up to 13 regions!
