Fujitsu Alternative
Smarter, Scalable and Software-Defined
Fujitsu’s storage platforms relies on proprietary hardware, legacy scaling methods, and costly maintenance contracts. If you're seeking an alternative to Fujitsu storage systems, simplyblock™ delivers a faster, more flexible, and cloud-ready software-defined storage platform—purpose-built for dynamic workloads and modern infrastructure demands. It enables teams to move faster, reduce complexity, and avoid vendor constraints that slow innovation.
Where Fujitsu Falls Behind
High Ownership Costs
Fujitsu’s hardware-first model raises long-term costs with infrastructure lock-in, recurring fees, and restrictive support terms.
Rigid Scalability
Scaling storage with Fujitsu requires controller upgrades, planned downtime, and reconfiguration across environments.
Limited Deployment Options
Fujitsu lacks flexibility for hybrid, edge, and Kubernetes-native setups—slowing innovation and infrastructure evolution.
Why Simplyblock™ Wins
Simplyblock eliminates legacy storage limits with a true software-defined model and no vendor lock-in. Its NVMe-over-TCP design connects fast block and cloud storage, cutting latency and controller complexity. With erasure coding and automated balancing, it delivers high performance, efficiency, and resilience at lower cost.
Deployment Flexibility
Fujitsu's storage architecture is heavily appliance-driven, limiting support for hybrid, edge, or Kubernetes-native environments.
As an alternative to rigid appliance-based systems, simplyblock enables flexible deployments across disaggregated, hyperconverged, and hybrid models—whether on bare-metal servers, private cloud, or containers.
No rigid hardware paths or deployment constraints—just freedom to build infrastructure your way.
Modern Architecture
Fujitsu depends on traditional controller-based systems that cap performance and require hardware upgrades to scale.
Simplyblock uses a distributed scale-out architecture where each new node adds instant capacity and speed. With NVMe-over-TCP and erasure coding, it eliminates bottlenecks and delivers fast, resilient storage with minimal overhead.
It’s built to grow seamlessly with your infrastructure—without disruption or expensive hardware cycles.
