Cloud DVX is a cloud-native version of its architecture that allows software-as-a-service (SaaS) backup and recovery, in which customers can add the cloud as a site in their Datrium infrastructure.
Datrium’s on-site hardware architecture comprises NVMe flash cards in host servers, also known as DVX Compute Nodes, while bulk storage is handled by 7,200 rpm SATA spinning disk or the recently added flash option, Flash End-to-End.
In Cloud DVX, this architecture is mirrored off-site, with compute nodes in Amazon EC2 and storage nodes in S3.
In 2018, Datrium plans to add more cloud providers, disaster recovery-as-a-service and analytics capabilities. Chief use cases targeted are those that are already running Datrium DVX on-site and that want an off-site copy, as well as a tape replacement.
A key benefit, said Datrium marketing vice-president Craig Nunes, is that it hides complexity in AWS for the customer.
“To use AWS for hybrid cloud is difficult, in general, because there are lots of products you have to knit together correctly to make it work. You have to become a student to get it right,” he said.
“If you only use S3 as a backup target, you have to think about connecting to the cloud, transferring data back to premises, re-hydrating it and copying to primary storage. With Cloud DVX you don’t need to go to Amazon except to set up and pay the bills,” he added.
Cloud DVX is seeded by a full backup then maintains a forever incremental routine, which is global data deduplication between cloud instances.
Datrium is one of a number of flash storage makers focused on NVMe-based products. NVMe offers hugely increased input/output per second (IOPS) and lower latencies than existing flash products that use spinning disk-era connectivity methods and the SCSI protocol.
