QSAN Fabric Attached Storage

 XE5026D-100G

Born in Flash, Built for Agility

The QSAN XE5 is an NVMe-oF JBOF fabric attached storage that provides highdensity all-NVMe flash array and supports NVMe-oF connectivity, designed for performance-oriented enterprise environments. With flash-based architecture, the system delivers consistent low-latency response and high throughput, enabling efficient data access for AI workloads, database systems, and other data-intensive applications.

High-Performance End-to-End NVMe Architecture

The platform adopts a high-density NVMe SSD design to support parallel I/O processing and sustained throughput under demanding workloads, delivering up to 400 Gb/s bandwidth. With NVIDIA^® GPUDirect Storage support, XE5 ensures stable performance and minimizes response time impact across applications requiring continuous data access.

Scalable Performance Expansion

The system is designed to support flexible deployment across QSAN storage platforms and server direct-attached environments. By providing high-performance flash expansion that can be integrated with both QSAN systems and external servers, it enables organizations to adjust performance capacity based on workload requirements. This approach allows more efficient resource allocation and simplifies scaling in performance-driven scenarios across diverse infrastructure architectures.

Enterprise Availability

To ensure continuous operation, the platform adopts a redundant and modular hardware design. Key components are designed to support hot-swappable replacement, allowing maintenance without interrupting system operation. This design reduces service downtime and ensures stable operation for business-critical environments

Simplified Management

The platform supports centralized management through the QSAN XInsight platform, enabling administrators to monitor, control, and coordinate operations across multiple systems from a unified interface. With cross-system interaction consolidation capabilities, XInsight allows administrators to manage resources, monitor performance, and streamline workflows across storage environments.
