What Peer Global File Service is

Peer Global File Service, also called PeerGFS, replicates, manages, and synchronizes files across sites, platforms, clouds, and storage systems. Real-time change replication supports active-active sharing between locations, data centers, and cloud availability zones, while distributed locking is designed to avoid conflicting versions. Delta replication transfers changed portions instead of entire files. PeerGFS supports SMB and NFS workloads and lists Windows and Linux file servers, NetApp, Nutanix Files, Dell systems, Amazon S3, Azure Blob, NetApp StorageGRID, and Nutanix Objects among its environments. Microsoft DFS Namespace integration can provide one SMB namespace and support failover and failback. The product describes SSL encryption up to AES-256, Active Directory role-based controls, suspicious-activity monitoring, local caching, metadata and access preservation, cutover orchestration, and migration reporting. Pricing is available on request, with a trial request and guided proof of concept.

Who it suits

It is aimed at distributed project teams and enterprise environments using multi-site, multi-platform, or hybrid multi-cloud storage. Organizations needing file replication, migration, and failover controls may find its workload coverage relevant.

What it does well

Replicates changes in real time across locations
Distributed locking helps prevent version conflicts
Delta replication transfers changed file portions
DFS integration supports failover and failback
Includes migration reporting and cutover orchestration

What to know first

Edge caching supports Windows file servers only
NFS is limited to replication and synchronization jobs
Pricing is available only on request
Some NFS collaboration and backup functions are unavailable

Limits

There is no free plan; a trial is available by request as a guided proof of concept. NFS workloads are limited to file replication and synchronization, and edge caching is supported only for Windows file servers.
