HighPoint RocketRAID 3742A SAS Controller

The HighPoint RocketRAID 3742A SAS Controller is a professional-class hardware RAID adapter designed to delivers enterprise-grade reliability and performance for servers, workstations, and storage-centric workflows. As part of the RocketRAID 3700 series, this SAS controller leverages two decades of HighPoint RAID and storage expertise to provide robust, cost-effective storage solutions that keep data protected and accessible under demanding workloads. Built to maximize data throughput and minimize CPU overhead, the 3742A is an ideal choice for workloads that demand consistent I/O, predictable latency, and quick RAID rebuilds in mixed SAS and SATA environments.

• Hardware-accelerated SAS 12Gb/s performance: The 3742A is engineered with a dedicated hardware RAID engine to offload parity calculations and rebuild tasks from the host processor. This accelerates disk I/O, improves system responsiveness during sustained transfers, and helps maintain steady performance in multi-drive configurations. With SAS 12Gb/s support, you benefit from high-bandwidth paths that reduce bottlenecks in data-intensive environments such as databases, virtualization, media editing, and large-scale backups.
• Flexible RAID capabilities for data protection and efficiency: This controller supports a comprehensive set of RAID levels to match your data protection strategy and budget, including common configurations such as RAID 0, 1, 5, 6, 10, and JBOD. The hardware RAID approach delivers consistent rebuild times and improved fault tolerance, helping minimize downtime in the event of drive failure. Combine RAID levels with online capacity expansion and migration to grow storage without downtime, keeping workloads online while you scale.
• Broad OS and virtualization compatibility: The RocketRAID 3742A is designed to work across a wide range of operating systems and virtualization platforms. Whether you’re deploying Windows Server, various Linux distributions, or virtualized environments like VMware and Hyper-V, this controller is built to integrate smoothly with your existing stack, supported by updated drivers and management utilities that simplify installation and ongoing maintenance.
• Comprehensive management for reliability and efficiency: HighPoint provides robust management tools to configure, monitor, and optimize the 3742A’s performance and reliability. Features typically include a user-friendly management interface, firmware updates, SMART/status monitoring, and build-time configuration options that let you tailor cache policies, parity strategies, and reliability settings to your workloads. This empowers IT teams to keep storage performance predictable while preserving data integrity and uptime.
• Scalable, enterprise-ready design: The 3742A is built to handle demanding storage environments with multiple drive enclosures and expansion options. Its architecture supports scalable storage strategies, enabling larger arrays as data growth accelerates. The controller’s robust design emphasizes long-term reliability, making it suitable for data centers, high-demand workloads, and professional studios that require consistent performance with minimal maintenance.
