CISCO - 03-27010-05D - Cisco 12G SAS modular RAID card

Product Overview

The CISCO 03-27010-05D is a 12G SAS modular RAID card designed to add hardware RAID capability to compatible Cisco server platforms. By offloading RAID processing to a dedicated controller and supporting 12Gb/s SAS connectivity, it helps protect data and improve storage reliability for business-critical workloads in rack deployments.

This controller is a practical choice when maintaining or expanding existing RACK SERVER environments, where consistent performance and predictable rebuild behaviour are important. It is commonly deployed alongside enterprise drives such as SSD and HDD media, depending on whether your priority is latency, capacity, or a balanced tiered approach.

Key Features

Key technical characteristics of the Cisco 03-27010-05D RAID controller for professional server storage builds:

• 12G SAS interface support to connect modern SAS backplanes and drives for higher link speeds in supported server configurations.
• Modular RAID controller form factor to fit compatible Cisco server models that use this modular RAID card design.
• Hardware RAID functionality to provide data protection and availability in the event of disk failure.
• Support for common RAID levels (model-family typical) to balance performance, capacity, and redundancy based on workload requirements.
• Controller-based caching architecture (platform dependent) to improve write handling and overall I/O responsiveness for mixed workloads.
• Designed for integration with Cisco server storage backplanes to simplify maintenance and keep cabling and airflow aligned with OEM chassis layouts.
• Enterprise-grade component design to support 24/7 operation in data center and server room environments.
• Suitable for lifecycle maintenance to keep existing server nodes consistent when replacing failed or aging RAID hardware.

Refurbished Quality and Warranty

This unit is refurbished, cleaned, and tested by technicians before entering stock to help reduce the risk of hardware defects. Refurbished RAID controllers are a cost-effective way to extend the lifecycle of installed Cisco infrastructure while also reducing electronic waste.

All refurbished hardware from Direct Hardware Supply includes a one-year warranty from the date of purchase (batteries, tape drives, and tape libraries include a three-month warranty). Extended warranty options are available on request, and we ship worldwide from Denmark. For broader Cisco infrastructure sourcing, you can also explore CISCO product options.
