What Is CVR-CFP2-CPAK10=? Cisco’s 100G Mult
CVR-CFP2-CPAK10= Unveiled: Bridging the Gap Between Spe...
The Cisco UCSC-RAID-M6T= is a 12G SAS RAID controller designed for Cisco UCS C-Series rack servers (C220/C240 M6), supporting 16 direct-attached drives with 4GB Flash Backed Write Cache (FBWC). Built on Broadcom’s SAS3916 chipset, this controller implements hardware-accelerated RAID 6 with dual parity protection using Galois Field arithmetic for XOR operations. Key innovations include:
The controller employs dual parity algorithms (P+Q) to withstand simultaneous dual drive failures – a critical requirement for hyperscale NVMe-oF deployments. Unlike software RAID implementations, the UCSC-RAID-M6T= offloads parity calculations to dedicated ASICs:
Performance Impact Mitigation:
In 32-node NVIDIA DGX A100 configurations, the controller achieved 9.2M IOPS for 8K random reads with 650μs latency – 22% faster than software RAID 6 implementations. The persistent cache mirroring feature maintained <5ms write latency during 40% cache saturation scenarios.
When managing 128TB DICOM datasets on Pure Storage FlashArray//XL170, the UCSC-RAID-M6T= demonstrated:
For Oracle ZFS-backed trading systems, the controller’s atomic write acceleration reduced journal commit latency from 850μs to 120μs during 50K TPS workloads.
The controller operates within Cisco’s Full-Stack Observability framework through:

While competing solutions offer broader hypervisor support, the UCSC-RAID-M6T= dominates in Cisco-powered infrastructures through Intersight’s machine learning-driven cache optimization.
During a recent autonomous vehicle data lake deployment, engineers discovered that 40% of the controller’s cache remained underutilized during off-peak hours. By implementing Cisco Intersight’s Adaptive Cache Partitioning, they dynamically reallocated resources between metadata (25%), write acceleration (50%), and read-ahead (25%) – achieving 18% higher throughput without hardware upgrades. This breakthrough underscores a critical paradigm shift: RAID controllers are evolving from static data protectors to AI-driven storage orchestrators. The UCSC-RAID-M6T= exemplifies how Cisco’s co-design philosophy transforms hardware into policy-enforced intelligence layers – where every parity calculation serves dual purposes of data integrity and predictive analytics.
