NexentaStor vs ZetaNAS

NexentaStor is software-defined storage for enterprise applications, combining file services over NFS and SMB with block services over Fibre Channel and iSCSI. It is presented for databases, enterprise NAS, private cloud, virtual workloads, backup, and archives, and can scale from terabytes to petabytes. It runs on bare-metal hardware or as a virtual storage appliance in private-cloud and hyper-converged environments. Its perpetual license includes inline data reduction, unlimited snapshots, long-distance replication, and NexentaFusion management. Administrators can also use a VMware vCenter plugin or a self-documenting REST API. Named integrations or certifications include VMware, Microsoft, OpenStack, Commvault, Veeam, and NetBackup. Nexenta describes SMB 3 encryption and Windows-style access control lists for file storage, and a checksummed, self-healing filesystem for backup. Enterprise Edition includes scheduled replication for recovery point objectives of 15 minutes or longer; continuous replication requires an extra license. Pricing is on request, with a 45-day trial available after registration.

ZetaNAS is an open-source network-attached storage platform for SMBs, startups, and teams running AI or machine-learning workloads. It combines file sharing, collaboration, and data pipelines with native S3 and POSIX access, plus NFS/PNFS support. The system runs on mainstream x86 or ARM hardware and can expand from one server to distributed clusters. Built-in deduplication, erasure coding, and intelligent compression are described as reducing physical storage use by 30% or more. Security and reliability features include EC replication, disk-health monitoring, fault isolation, access control, and auditing. Media tools provide multi-device sync, version history, previews, and chunked transfer. Shared workspaces add real-time synchronization and granular access control. Medical deployments support DICOM and WSI data, annotation, and quality control. AI workloads can stream through S3 and FUSE to GPU nodes. A Docker-based app store manages extensions.
