IBM Copy Services Manager vs Peer Global File Service

IBM Copy Services Manager has no write-up on Specifiction yet; its figures are above.

Peer Global File Service (PeerGFS) replicates, manages, and synchronizes files across sites, platforms, clouds, and storage systems. It sends changes in real time for active-active file sharing, uses distributed file locking to help prevent conflicts, and transfers changed data rather than whole files through delta-level replication. The product supports SMB and NFS workloads and lists Windows and Linux file servers, NetApp, Nutanix Files, Dell systems, and cloud targets including S3 and Azure Blob. Microsoft DFS Namespaces can unify SMB access across sites and support failover and failback. Security descriptions include SSL-encrypted traffic up to AES-256, role-based controls through Active Directory, and monitoring for suspicious file activity. The product also lists local caching, edge synchronization, metadata and access preservation, cutover orchestration, and migration reporting. Capabilities depend on configuration: edge caching is limited to Windows file servers, and NFS supports only replication and synchronization jobs. Pricing is available on request. A trial request includes a guided proof of concept with the pre-sales team. Peer Software says it began in 1993.
