Overview of the CBL-SAS-C220M7=

The ​​CBL-SAS-C220M7=​​ is a Cisco-certified ​​SAS (Serial Attached SCSI) cable​​ optimized for high-speed data transfers between storage arrays, servers, and JBODs (Just a Bunch of Disks) in enterprise environments. With a ​​220-meter length​​ and ​​SFF-8644 HD Mini SAS connectors​​, it supports 12 Gbps SAS 3.0 protocols, enabling reliable, low-latency communication for data-heavy workloads like databases, virtualization, and real-time analytics.

Key Technical Specifications

• ​​Cable Type​​: ​​24 AWG​​ copper twinaxial cable with shielded design for EMI reduction.
• ​​Length​​: 220 meters (722 feet).
• ​​Connectors​​: ​​SFF-8644 to SFF-8644 HD Mini SAS​​ with latching mechanisms.
• ​​Data Rates​​: Supports ​​12 Gbps SAS 3.0​​, backward-compatible with 6 Gbps SAS 2.0.
• ​​Compliance​​: Meets ANSI T10 and SAS 3.0 standards.

Addressing User Concerns

​​Q: Can this cable connect non-Cisco SAS devices?​​
A: Yes. The ​​SFF-8644 connectors​​ are industry-standard, ensuring compatibility with Dell, HPE, or NetApp storage systems. However, performance guarantees apply only when used with Cisco-validated hardware.

​​Q: How does SAS compare to NVMe or Fibre Channel for storage?​​
A: ​​SAS 3.0​​ excels in ​​mixed read/write workloads​​ due to its command queuing efficiency, while NVMe outperforms in pure latency-sensitive tasks. SAS remains cost-effective for mid-range storage tiers requiring scalability and reliability.

Optimal Deployment Scenarios

• ​​Enterprise Storage Expansion​​: Linking SAN/NAS systems to backup servers in data centers.
• ​​Big Data Analytics​​: Transmitting large datasets between Hadoop clusters and SAS JBODs.
• ​​Video Surveillance Archives​​: High-throughput writes for multi-camera NVR setups.

Procurement and Authenticity

The ​​CBL-SAS-C220M7=​​ is available through authorized Cisco partners like itmall.sale. Counterfeit cables often lack proper shielding, leading to EMI-induced errors in densely packed server racks.

On-Site Observations

During a recent deployment for a logistics firm’s cold storage analytics platform, the ​​CBL-SAS-C220M7=​​ outperformed unshielded cables in ​​noisy electrical environments​​, maintaining consistent throughput for temperature and inventory telemetry. While NVMe is gaining traction, SAS’s backward compatibility and lower overhead make this cable a pragmatic choice for hybrid storage ecosystems—especially legacy systems where phased upgrades are necessary. For teams balancing performance and budget, its 220-meter reach also avoids costly mid-span repeaters in sprawling data halls.
