Promise SAN Array: 12-Bay 2U Rack-Mount SAN Storage System

The Promise SAN Array is a high-density, enterprise-grade storage solution engineered for data centers, virtualization hosts, and demanding backup workflows. Built in a compact 2U rack-mountable chassis, this system brings together robust drive capacity, reliable data pathways, and scalable performance to meet today’s data growth. With 12 bays ready to host up to 12 hard disk drives and a total installed HDD capacity of 48 TB, it offers a powerful platform for consolidating your block storage needs, accelerating I/O-bound applications, and simplifying storage management in busy IT environments. Dual 12 Gb/s SAS controllers ensure fast, redundant data paths, helping you maintain uptime while delivering responsive performance for databases, virtual machines, file services, and media libraries. This Promise SAN Array blends practical expandability with a streamlined management experience, making it a versatile cornerstone for modern storage architectures.

• High-capacity 12-bay design in a 2U chassis: This rack-mountable SAN storage system is purpose-built to maximize space efficiency while delivering ample room for growth. It is ideal for mid-sized enterprises and data centers that need reliable, scalable storage without sacrificing rack footprint. The 12 bays provide a straightforward path to expanding capacity as your data footprint grows, enabling you to plan for future workloads, intensive databases, and virtualization platforms with confidence.
• 48 TB installed HDD capacity for immediate workflow acceleration: With 48 TB of installed HDD capacity, you can provision large storage pools for virtual desktops, backups, media libraries, and big data applications. This substantial capacity helps reduce fragmentation of storage resources and minimizes the frequency of expansion cycles, letting you focus on optimizing performance and data protection rather than chasing capacity. It also supports long-term retention policies and faster data recovery timelines in local and hybrid environments.
• Dual 12 Gb/s SAS controllers for dependable performance: The Promise SAN Array features two 12 Gb/s SAS controllers to provide high-throughput data paths with redundancy. This dual-controller design helps improve IOPS, reduce bottlenecks, and deliver consistent performance under load. With failover paths in place, you can sustain operations during controller maintenance or component failures, contributing to higher uptime and more predictable storage behavior for business-critical workloads.
• 12 total bays and flexible drive management for scalable storage: The 12 bays offer a flexible foundation for configuring RAID-protected arrays, pools, and capacity tiers. Whether you’re optimizing for high read throughput, sequential workloads, or mixed I/O profiles, this chassis supports practical storage configurations that align with your performance goals and disaster-recovery plans. The design also simplifies drive replacement and maintenance, helping IT teams keep storage available and healthy with minimal disruption.
• Rack-mountable, enterprise-grade reliability with streamlined management: Engineered for data centers and enterprise environments, the Promise SAN Array fits standard 19-inch racks and integrates with common storage management workflows. Its compact 2U form factor, combined with robust controllers and straightforward provisioning tools, helps operators deploy, monitor, and scale storage efficiently. This foundation supports business continuity, data protection strategies, and consistent service delivery across cloud-integrated infrastructures.

how to install Promise SAN Array

• Prepare the rack: ensure adequate space, stable mounting, proper grounding, and sufficient cooling. Verify power availability and consider redundant power options if supported in your environment.
• Mount the SAN Array in the rack: use cage nuts and mounting rails to secure the 2U chassis firmly. Confirm that connections to the rack’s power distribution unit (PDU) and cooling system are in place before powering on.
• Install or verify drives: if drives are not pre-installed, insert up to 12 HDDs into the 12 bays, ensuring each drive is seated firmly and aligned with the chassis guides. If drives are already installed, perform a quick health check to ensure all bays are populated correctly.
• Connect data paths: attach SAS cables from the SAN array to the host servers or to a storage controller/switch fabric as required by your infrastructure. Use cable management to avoid airflow obstructions and ensure secure, labeled connections for easier future maintenance.
• Power up and configure: boot the system and access the management interface. Create storage pools or RAID configurations as appropriate for your workloads, assign LUNs or volumes to hosts, and integrate with your existing monitoring, backup, and virtualization platforms.
• Validate performance and protection: run baseline performance tests, verify data redundancy, and configure snapshotting or replication features if available. Establish monitoring alerts and define maintenance windows to keep the system healthy over time.
