Hardware Architecture & Interface Specifications

The ​​UCSC-SAS-240M6=​​ is Cisco’s 6th-generation 24Gb/s SAS controller designed for UCS C240 M6 rack servers, supporting ​​4.8M sustained IOPS​​ in mixed read/write workloads. Built on Broadcom SAS3916 ROC (RAID-on-Chip) architecture, this PCIe 4.0 x8 controller features:

• ​​Dual SAS4 ports​​ with 24Gb/s per lane (backward-compatible with 12/6/3Gb SAS)
• ​​8GB DDR4-3200 cache​​ with supercapacitor-backed flash protection
• ​​NVMe-oF acceleration​​ via SCSI Express (SCSIe) protocol offload

​​Key innovation​​: ​​Adaptive Path Failover Technology​​ maintains <50ms failover latency during dual-controller synchronization, achieving 99.999% availability in hyperscale storage pools.

Why This Controller Redefines Storage Economics
Three operational truths from 300+ PB-scale deployments:


​​SAS4 ≠ Legacy SAS​​ – A video surveillance provider reduced storage latency by 62% using ​​24Gb/s multipathing​​, enabling real-time 8K facial recognition across 50,000 cameras.


​​Encryption Isn’t Optional​​ – Healthcare archives achieved HIPAA compliance without performance loss via ​​AES-NI指令集加速​​, maintaining 22GB/s throughput during full-disk encryption.


​​Edge Demands Ruggedness​​ – Offshore oil rigs extended drive lifespan by 41% using the controller’s ​​vibration compensation algorithm​​, surviving 15Hz–2kHz mechanical resonance.


For enterprises bridging cloud and edge storage demands, this isn’t just another HBA – it’s the backbone preventing exabyte-scale data silos while delivering deterministic microsecond latency. Procure before Q1 2026; global 24Gb SAS component shortages are projected as AI training datasets grow 300% YoY.
