EdgeFS Data Fabric

EdgeFS is capable of spanning unlimited number of geographically distributed sites (Geo-site), connected with each other as one global name space data fabric running on top of Kubernetes platform, providing persistent, fault-tolerant and high-performance volumes for stateful Kubernetes Applications.

At each Geo-site, EdgeFS nodes deployed as containers (StatefulSet) on physical or virtual Kubernetes nodes, pooling available storage capacity and presenting it via compatible S3/NFS/SMB/iSCSI/etc storage emulated protocols for cloud-native applications running on the same or dedicated servers.

Design

Rook enables easy deployment of EdgeFS Geo-sites on Kubernetes using Kubernetes primitives.

With Rook running in the Kubernetes cluster, Kubernetes PODs or External applications can mount block devices and filesystems managed by Rook, or can use the S3/S3X API for object storage. The Rook operator automates configuration of storage components and monitors the cluster to ensure the storage remains available and healthy.

The operator will monitor the storage Targets to ensure the cluster is healthy. EdgeFS will dynamically handle services failover, and other adjustments that maybe made as the cluster grows or shrinks.

The EdgeFS Rook operator also comes with tightly integrated CSI plugin. CSI pods deployed on every Kubernetes node. All storage operations required on the node are handled such as attaching network storage devices, mounting NFS exports, and dynamic provisioning.
