Red Hat is putting its bought-in Gluster scale-out NAS storage technology, acquired in October, on the Amazon cloud.

It’s styled Red Hat Virtual Storage Appliance for Amazon Web Services and other clouds are supposed to follow in short order.

It’ll let companies burst their unstructured data center storage to the cloud and aggregate both Amazon Elastic Block Storage (EBS) and Amazon Elastic Compute Cloud (EC2) instances for a highly available petabyte-size virtualized storage pool.

It features both synchronous and asynchronous file replication. Synchronous replication provides redundancy and protection in a single data center or multiple data centers and availability zones in a region, while asynchronous geo-replication offers data availability across all AWS Regions.

Red Hat says it can be deployed in minutes; offers EC2 customers greater availability, performance and utility pricing; and, unlike cloud-based object storage (S3), needs no application rewrites because it’s POSIX-compliant. Users should be able to scale linearly for performance and capacity – achieving a better SLA – and connect multiple AWS instances to a single shared storage pool.

Director of storage marketing John Kreisa said to figure $7,500 per instance.

Red Hat moved the Gluster widgetry from CentOS to its own distribution in December releasing it as its Storage Software Appliance. It also supports XFS for greater stability.
