Core Design and Technical Role
The CBL-R1B-SD-240M6= is a Cisco-certified internal storage backplane cable designed for the UCS C240 M6 rack server. It connects the server’s motherboard to its drive backplane, enabling high-speed communication between SAS/SATA controllers and installed drives (HDDs/SSDs). This cable is critical for maintaining data integrity and throughput in storage-heavy configurations.
- SAS3/SATA III Support: Delivers up to 12 Gbps per lane, ensuring minimal bottlenecks for enterprise workloads like databases or virtualized storage.
- Dual-Channel Redundancy: Supports failover configurations to prevent single points of failure in RAID setups.
- UCS C240 M6-Specific Design: Precision-engineered pin alignment ensures compatibility with the server’s onboard LSI SAS3008 controller.
Addressing Central User Concerns
“Is this cable required for all UCS C240 M6 drive configurations?”
Yes. The CBL-R1B-SD-240M6= is mandatory when populating drive bays 1-12 with SAS/SATA drives. Without it, the server cannot recognize or communicate with installed storage devices.
“Can I reuse cables from older UCS C-Series servers?”
No. Previous-generation cables (e.g., CBL-R1B-SD-240M5) have different pinouts and lengths. Improper reuse risks drive detection failures or reduced transfer speeds.
“Does it support NVMe drives?”
No. This cable is designed for SAS/SATA drives only. For NVMe configurations, use Cisco’s CBL-NVMe-240M6= cable and corresponding backplane.
Sourcing Authentic CBL-R1B-SD-240M6= Cables
Purchase only from authorized Cisco partners like itmall.sale to avoid counterfeit cables that lack EMI shielding, which can corrupt data during high-volume transactions.
Real-World Application Insights
During a recent ERP system migration, replacing a generic SAS cable with the CBL-R1B-SD-240M6= resolved intermittent drive dropout issues under heavy IOPS loads. While unglamorous, this component is the unsung hero of storage reliability—any cost-cutting here risks cascading failures. For UCS C240 M6 deployments, treating this cable as mission-critical is non-negotiable.
