Fujitsu ETERNUS DX900 S6 Hybrid Storage Array

The Fujitsu ETERNUS DX900 S6 represents the flagship tier of the ETERNUS DX S6 product generation, purpose-built for large-scale enterprise environments that require the performance density of flash with the economic capacity of spinning disk. The array's architecture places up to 96 NVMe SSDs in a dedicated high-speed cache tier, while SAS hard disk drives provide deep, cost-efficient capacity for cold and warm data. Fujitsu's Autonomous Storage Tiering AI engine continuously monitors I/O heat maps at the sub-LUN level and migrates data blocks between tiers without administrator intervention, ensuring that the most frequently accessed data always resides on NVMe media while infrequently accessed data is transparently demoted to SAS capacity pools. The result is a system that dynamically self-optimizes across diverse, mixed workloads without manual tuning cycles.

The DX900 S6 is architected around a fully redundant dual-controller design with no single point of failure across controllers, cache modules, power supplies, fans, and interconnects. The system supports synchronous and asynchronous remote replication, enabling active-active stretched clustering between data centers for zero-RPO/near-zero-RTO disaster recovery configurations. Inline data reduction technologies including compression and deduplication operate transparently across both the NVMe cache tier and the SAS capacity tier, extending effective usable capacity well beyond raw physical figures. The array's scale-out enclosure model supports incremental non-disruptive expansion of both drives and controller resources, protecting infrastructure investments as workload footprints grow.

Security and compliance are first-class design considerations in the ETERNUS DX900 S6. End-to-end AES-256 encryption covers data at rest across every drive in the system, with support for self-encrypting drives (SED) and external KMIP-compatible key management server integration to satisfy regulated industries including financial services, healthcare, and government. The management plane enforces role-based access control (RBAC), audit logging, and multi-factor authentication hooks. Certified against common industry security frameworks, the DX900 S6 is a compelling candidate for organizations operating under HIPAA, PCI-DSS, GDPR, or national cybersecurity mandates that require demonstrable data protection controls throughout the full storage stack.

Ideal for

• Large-scale Oracle and SAP HANA database consolidation requiring sub-millisecond latency on hot data sets with petabyte-class capacity for historical records
• Virtualization platform storage backends (VMware vSphere, Microsoft Hyper-V) supporting thousands of virtual machines with consistent QoS and automated tiering across mixed workloads
• Healthcare imaging archives (PACS/RIS) combining high-throughput NVMe access for active studies with compliant, encrypted long-term retention on SAS capacity tiers
• Financial services trading platforms and data warehouses demanding high IOPS, low latency, and end-to-end AES-256 encryption to meet PCI-DSS and regulatory audit requirements
• Hybrid cloud tiering and backup target integration, serving as an on-premises anchor for data lifecycle management policies that offload cold data to object storage or cloud gateways
• High-performance analytics and AI/ML training pipelines that require rapid sequential throughput for large dataset ingestion alongside deep capacity pools for model storage and versioning
