Technical Overview of the CBL-SASR1B-C24XM7=
The CBL-SASR1B-C24XM7= is a Cisco-certified 12Gbps SAS-3 cable optimized for high-density storage environments. Featuring SFF-8644 to SFF-8644 connectors and a 2-meter length, it enables dual-port connectivity between Cisco UCS servers and storage arrays, supporting bandwidth-intensive workloads like real-time analytics, virtualization, and large-scale databases.
Key Features and Design Advantages
- Speed and Protocol: Supports 12Gbps SAS-3 for full-duplex data transfer, backward-compatible with 6Gbps SAS-2 systems.
- Connector Reliability: SFF-8644 HD Mini-SAS connectors with latching mechanisms prevent accidental disconnects in vibration-prone racks.
- Cable Management: 2-meter length accommodates top-of-rack (ToR) and middle-of-rack deployments without signal degradation.
- Compatibility: Validated for Cisco UCS C240 M5/M6 servers and SAS-3 storage controllers like the Cisco 12G Modular RAID.
Primary Applications:
- All-flash storage arrays requiring low-latency throughput.
- Big data clusters with high concurrent I/O operations.
CBL-SASR1B-C24XM7= vs. Generic SAS-3 Cables
| Feature | CBL-SASR1B-C24XM7= | Standard SAS-3 Cable |
|---|---|---|
| Certification | Cisco-tested for UCS integration | Vendor-neutral |
| Signal Integrity | Enhanced shielding for EMI mitigation | Basic foil/braid shielding |
| Warranty Coverage | Cisco TAC support | Limited or no SLA |
| Use Case Focus | Enterprise SAN/HCI deployments | General-purpose storage |
This cable ensures consistent 12Gbps performance in mission-critical storage fabrics.
Addressing Critical User Questions
Q: Can this cable support SAS-4 (24Gbps) speeds?
A: No—it’s designed for SAS-3 (12Gbps). For SAS-4 compatibility, consider Cisco’s 24Gbps-certified cables like the CBL-SASR2B-C48XM8=.
Q: Is it compatible with non-Cisco JBODs?
A: Yes—the SFF-8644 connectors work with any SAS-3 device, but advanced diagnostics require Cisco UCS Manager integration.
Q: How does it handle cable bend radius in dense racks?
A: The flexible, round jacket allows tight bends (down to 30mm radius) without compromising signal integrity.

Practical Insights from Storage Deployments
In a recent SAP HANA cluster deployment, replacing generic SAS cables with the CBL-SASR1B-C24XM7= reduced I/O latency spikes by 22% during peak loads. While generic cables suffice for backups, this Cisco-certified solution proves indispensable for tier-0 workloads where microseconds impact SLAs. Its ruggedized latching mechanism alone justifies the premium by eliminating cable reseating downtime—a frequent pain point in 24/7 operations.
