Fujitsu ETERNUS AB 4000 S2 All-Flash Storage

The Fujitsu ETERNUS AB 4000 S2 is a next-generation all-flash storage system built on a purpose-designed NVMe-native architecture, delivering end-to-end NVMe over Fabrics (NVMe-oF) connectivity across both front-end host interfaces and back-end drive enclosures. Unlike hybrid or retrofitted all-flash platforms, the AB 4000 S2 eliminates legacy SCSI protocol overhead entirely, enabling consistent sub-100 microsecond read latency and predictable I/O performance under sustained mixed workloads. The system is purpose-engineered for latency-sensitive enterprise applications including OLTP databases, in-memory analytics, and high-frequency transaction processing where I/O determinism directly impacts application SLAs.

At the core of the AB 4000 S2 is Fujitsu's inline data reduction engine, which performs simultaneous deduplication and compression in real time without offloading to background processes, preserving low latency while dramatically improving effective capacity utilization. The array ships with advanced RAID-6 equivalent data protection enhanced by distributed sparing and proactive media monitoring, ensuring resilience against multiple simultaneous drive failures without impacting foreground I/O. Dual active-active controllers with non-disruptive failover guarantee continuous availability for tier-1 workloads, and the integrated cache architecture leverages persistent NVDIMM-backed write cache to eliminate data-loss exposure during power events.

The ETERNUS AB 4000 S2 integrates natively with Fujitsu ETERNUS SF storage management software, offering policy-based automated tiering, granular QoS controls, and comprehensive monitoring through a RESTful API framework that supports DevOps and infrastructure-as-code workflows. Enterprise orchestration integrations include VMware vSphere, Microsoft Hyper-V, Red Hat OpenShift, and Kubernetes persistent volume provisioning via a certified CSI driver. The system's scale-out architecture supports non-disruptive capacity and performance expansion, making it suitable for organizations anticipating rapid data growth without planned maintenance windows.

Ideal for

• Accelerating Oracle, SAP HANA, and Microsoft SQL Server OLTP databases requiring deterministic sub-millisecond I/O response times at scale
• Supporting high-frequency financial trading platforms and real-time settlement systems where microsecond latency variance directly affects transaction integrity
• Providing shared persistent storage for containerized and Kubernetes-native microservices workloads demanding high IOPS with low-latency block access
• Consolidating multiple tier-1 virtualized workloads onto a single high-density NVMe-oF fabric without performance isolation compromise
• Serving as primary storage for AI/ML training data pipelines and inference serving infrastructure requiring sustained sequential and random read throughput
• Replacing legacy SAN arrays in enterprise data centers seeking to reduce rack footprint, power consumption, and operational complexity while improving performance SLAs
