RAID / Controller Compatibility
- Cisco 12G Modular RAID controllers
- Cisco Modular SAS HBAs
- Fully compatible with SATA RAID and AHCI environments
Important Compatibility Notes
- SATA interface (not SAS or NVMe)
- Fits both 7mm and 15mm 2.5" drive bays
- Hybrid bays supported (SAS/SATA compatible on most UCS systems)
- May not report full health/SMART data in Cisco UCS Manager if non-Cisco firmware
- Requires correct Cisco tray/caddy for hot-swap use
- Ideal for virtualization, cloud, and read-intensive enterprise workloads
