Introduction
In an era where service interruptions can result in significant financial loss and reputational damage, maintaining continuous system availability is a top priority for enterprises. High availability (HA) infrastructure is essential to ensure critical applications and services remain operational even in the face of hardware failure, system fault, or unexpected disruptions. AEWIN’s MIS-5131-2U2 High Availability Storage Server is purpose-built to meet these demands with its resilient architecture, fast failover capabilities, and scalable performance.

Built for High Availability
The AEWIN MIS-5131-2U2 adopts dual-node architecture within a single 2U chassis to deliver seamless failover and system redundancy. It is designed with the following features for high availability to provide service continuity for mission-critical workloads.

• Dual-Node Design with PCIe Gen5 NTB
  Built with a dual-node architecture in a single 2U chassis, each node operates independently to ensure system-level redundancy. Through a PCIe Gen5 Non-Transparent Bridge (NTB), both nodes stay synchronized, enabling fast and coordinated failover. If one node fails, the other seamlessly takes over to maintain application availability.
• Redundant Storage with Dual-Port NVMe SSDs
  The server supports up to 24 hot-swappable dual-port NVMe SSDs. These drives provide not only high IOPS performance but also path redundancy. Should one controller or path fail, the system automatically reroutes I/O traffic through the alternate path, keeping services running uninterrupted.
• Intelligent System Management with BMC/IPMI
  The built-in baseboard management controller supports IPMI for out-of-band monitoring and control. With capabilities such as heartbeat detection and automatic failover triggers, the platform ensures continuous system supervision and rapid recovery in case of anomalies.
• High-Speed, Scalable I/O with PCIe Gen5
  Leveraging the Intel Xeon 6 (R1S) platform, each node supports up to 136 PCIe Gen5 lanes. This rich I/O bandwidth allows for high-throughput storage access, hardware acceleration, and expansion options such as high throughput networking or FPGA/GPU accelerator cards for various kinds of applications such as telecom, enterprise IT, and Edge computing.
• Hardware-Based Acceleration with Intel QAT
  Integrated Intel QuickAssist Technology Gen4 (QAT 4) delivers up to 200 Gbps of encryption and compression acceleration. Offloading these tasks to QAT accelerator significantly improves CPU efficiency and enables secure, low-latency data transactions even under peak loads.

Summary
AEWIN’s MIS-5131-2U2 is a robust and future-ready solution for enterprises building high availability infrastructure. Its dual-node architecture with PCIe Gen5 NTB, support for dual-port NVMe, advanced BMC-based system management, and flexible modular design enable seamless failover, reliable performance, and scalable deployment. For organizations aiming to minimize downtime and ensure continuous operations, the MIS-5131-2U2 serves as a resilient and dependable foundation for next-generation IT environments.
