Lenovo ThinkServer SA120 DAS Array with Dual Controller

The Lenovo ThinkServer SA120 DAS Array with Dual Controller is a modular, scalable direct attach storage solution built to grow with your business. Designed to complement ThinkServer host servers, this DAS array combines dense capacity with redundancy and performance. It offers twelve front-panel 3.5" bays for high-capacity storage, support for up to two I/O controllers, and optional rear-panel 2.5" SSD bays to accelerate workloads. With enterprise-grade reliability, flexible expansion, and streamlined management, the SA120 is ideal for backups, data warehouses, virtualized environments, and demanding applications that require scalable storage without complex infrastructure.

• Massive front-end capacity for scalable growth: The SA120 provides twelve 3.5" front-drive bays, enabling you to deploy large, dense storage arrays in a compact footprint. This design supports easy capacity expansion as your data grows, with hot-swappable trays that minimize downtime during drive upgrades or replacements.
• Redundant dual controllers for reliability and throughput: Up to two I/O controllers deliver enhanced throughput and high availability. Redundant controllers help maintain access to data even if one controller requires service, reducing the risk of downtime and keeping critical workloads running smoothly. The integration with LSI-based controller technology brings proven performance and robust management capabilities to your environment.
• Optional rear 2.5" SSD bays to accelerate performance: Four rear-panel 2.5" drive bays can be populated with SSDs to accelerate data-intensive workloads. This enables flexible tiering or caching strategies, delivering lower latency and higher IOPS for databases, virtualization, and high-traffic applications while preserving the cost benefits of HDD capacity in the front bays.
• Direct attach storage designed for Lenovo ThinkServer ecosystems: The SA120 is engineered to integrate seamlessly with Lenovo ThinkServer servers, simplifying deployment, cabling, and ongoing management. This cohesive ecosystem supports unified monitoring, firmware updates, and reliable sourcing from Lenovo, helping IT teams reduce time-to-value and streamline support.
• Modular, scalable architecture for futureproofing: Built to adapt to evolving data requirements, the SA120’s modular design lets you expand capacity and improve performance over time. Add drives or leverage the dual-controller configuration to balance capacity, resilience, and throughput as your workloads shift, ensuring your storage solution remains aligned with business goals.

How to Install Lenovo ThinkServer SA120 DAS Array

Installing the SA120 is a straightforward process when paired with compatible Lenovo ThinkServer hosts. Follow these general steps to deploy quickly and maintain reliability across your storage environment.

• Plan ahead: Verify compatibility with your ThinkServer model, confirm available rack or workspace space, and determine power and cabling requirements for SAS or other supported connections.
• Prepare the SA120: Ensure the unit is in a clean, static-free environment. If you are adding drives, install them into the front 3.5" bays and secure the trays properly. Inspect the rear area to confirm any optional SSD bays are properly installed if you intend to use them.
• Connect power and data cables: Attach the SA120 to an appropriate power source and connect the I/O cables from the host servers to the dual controller ports. Use clean, well-organized cabling to maximize airflow and simplify maintenance.
• Power up and initialize: Start both the SA120 and the ThinkServer host. Access the management interfaces (such as the LSI-based controller utility or ThinkServer management tools) to initialize the array, configure RAID levels, and establish volumes for your workloads.
• Configure storage policies: Create storage pools or RAID configurations that reflect your data protection and performance requirements. If you are using SSDs in the rear bays, implement caching or tiering policies to optimize access times for hot data.
• Validate and monitor: Run sample workloads to validate performance, confirm drive health, and verify failover paths for the redundant controllers. Enable monitoring features to receive alerts for drive failures, controller issues, or power anomalies.
• Document and secure: Record your configuration, include drive layout, RAID levels, and volume mappings in your IT documentation. Ensure firmware and driver updates are applied through Lenovo ThinkServer management channels to maintain reliability and security.
