RAID controller Cisco UCS-M2-HWRAID= with M.2 support

The RAID controller Cisco UCS-M2-HWRAID= with M.2 support is a hardware RAID adapter designed to work with M.2 storage drives in compatible Cisco UCS platforms. It provides RAID management and data protection at the controller level for systems that accept M.2 modules, enabling the configuration of RAID arrays across multiple M.2 SSDs to increase fault tolerance and streamline storage administration in compact server and edge deployments.

Advantages

This Cisco RAID controller offers dedicated hardware RAID processing to reduce CPU overhead and improve I/O reliability compared with software-based RAID. Support for M.2 form-factor drives enables high-density storage in space-constrained server environments. The controller simplifies array creation, monitoring, and rebuild operations, helping to maintain data integrity and uptime in multi-drive M.2 configurations.

Suitable for

• Compact servers and blade systems that accept M.2 storage modules
• Edge computing nodes and appliances requiring small-footprint RAID-protected storage
• Workloads needing improved data redundancy and simplified storage management
• Environments where lower CPU utilization for RAID tasks is preferred

Key specifications

• Form factor compatibility: M.2 storage drive support for use in compatible Cisco UCS systems
• Functionality: hardware RAID controller for managing RAID arrays across M.2 SSDs
• RAID levels: support for common RAID modes suitable for redundancy and performance (implemented at hardware level)
• Interface integration: designed for integration into Cisco UCS platforms that provide M.2 connectivity and power
• Management: controller-level array configuration, monitoring and rebuild support

How to use

Install the RAID controller into a compatible Cisco UCS server slot or module bay that provides M.2 connectivity following the server vendor's hardware installation instructions. Insert supported M.2 SSDs into the controller or the provided M.2 slots, then power on the system. Access the server management interface or the controller's configuration utility during boot to create RAID arrays, assign drives to arrays and configure desired RAID levels and caching policies. After configuration, initialize and format the logical volumes inside the host operating system before use.

Usage recommendations

Use identical capacity and performance-class M.2 SSDs when building RAID arrays to ensure predictable rebuild times and consistent performance. Monitor controller and drive health through the Cisco UCS management tools and schedule firmware updates for both the controller and attached drives according to Cisco guidance.
