About the NetApp AFF C400 All-Flash Array
The NetApp AFF C400 is a hybrid all-flash storage system engineered for organizations requiring high-capacity deployments without premium pricing constraints. Built on NetApp's ONTAP operating system, the C400 combines QLC NAND flash technology with intelligent data management to achieve superior density—supporting multi-petabyte configurations while maintaining predictable performance characteristics. The architecture employs a dual-controller active-active design with integrated RAID-TL (RAID-TP with Triple Parity) protection, enabling both high availability and efficient utilization of physical capacity.
Optimized for edge data centers, departmental storage clusters, and secondary storage workloads, the C400 target organizations balancing performance requirements against capital expenditure. The system supports both SAN (FC/iSCSI) and NAS (NFS/SMB) protocols simultaneously, allowing heterogeneous environments to consolidate storage infrastructure. NetApp's SnapVault and SnapMirror technologies enable efficient replication and backup integration, while built-in data compression and deduplication reduce effective capacity consumption by 3-5x depending on workload characteristics.
Launched in Q3 2023, the AFF C400 has gained significant adoption within mid-market enterprises and service providers seeking all-flash reliability with QLC economics. The platform supports 10/25/40/100GbE connectivity, enabling both traditional SAN environments and modern object storage use cases through S3-compatible APIs.
Ideal for
- Departmental file services and collaborative storage consolidation replacing legacy NAS appliances
- Secondary and backup storage target for disaster recovery and long-term retention with reduced TCO
- Edge computing data repositories supporting distributed analytics and AI/ML model training workflows
- Virtual desktop infrastructure (VDI) and virtual machine datastore acceleration for knowledge worker environments
- Database workload hosting including Oracle, SQL Server, and PostgreSQL with transactional consistency
- Object storage tier for cloud-native applications and container registry backends using S3 APIs
