Our vision for VMware Cloud Flex Storage is to deliver an enterprise-class storage-and data management-as-a-service for the multi-cloud. We plan to support a broad range of workloads by enabling multi-dimensional scaling of compute, storage performance, and storage capacity, while delivering a seamless and consistent data management experience across clouds.
VMware Cloud Flex Storage is built on a mature, enterprise-class filesystem that has been developed and production-hardened over many years, dating back to Datrium’s DHCI storage product, which VMware acquired in July 2020. It is the same filesystem that has been backing the VMware Cloud Disaster Recovery service. The filesystem has a two-tier design that allows for independent scaling of storage performance and capacity, using a Log-Structure Filesystem (LFS) design. You can read more about the filesystem architecture in Sazzala Reddy’s (Chief Technologist and a founder of Datrium) blog here. The combination of LFS with a 2-tier design, along with efficient snapshots and immutability, makes this a multi-purpose filesystem that unlocks many use cases, such as backup, disaster recovery, ransomware protection, and recovery. With VMware Cloud Flex Storage, we are extending this proven technology to primary storage and making it available in the public cloud, where it delivers exceptional storage performance, scalability, and cost efficiency for traditional and modern workloads.
In the initial release, we are delivering a new approach to help VMware Cloud on AWS customers better align their cloud resources with the needs of their applications and data. Customers will be able to purchase a disaggregated cloud storage and data management service that if fully managed by VMware. It is scalable, elastic, and natively integrated into VMware Cloud on AWS. With just a few clicks in the VMware Cloud Console, customers can scale their storage environment without adding hosts, and elastically adjust their storage capacity up or down as needed for every application. Customers also benefit from a simple pay-as-you-go consumption model. We are offering VMware Cloud Flex Storage as supplemental storage to vSAN. Together with vSAN, VMware Cloud Flex Storage offers more flexibility and customer value in terms of resilience, performance, scale, and cost in the cloud.
