CBL-SAS24-C240M7=: Why Is It Essential for Cisco UCS C240 M7 High-Density Storage?

Core Functionality and Technical Specifications

The ​​CBL-SAS24-C240M7=​​ is a ​​Cisco-certified SAS cable​​ designed specifically for the ​​UCS C240 M7 rack server​​, enabling connectivity between the server’s SAS controller and its drive backplane. This cable ensures high-speed data transfer for storage configurations, critical for applications like data analytics, virtualization, and large-scale databases.

• ​​SAS3 (12 Gbps) Support​​: Delivers full bandwidth for up to ​​24 drives​​ (HDDs/SSDs) in a single chassis, minimizing latency in I/O-intensive workloads.
• ​​Dual-Port Redundancy​​: Enables multipath I/O configurations to prevent single points of failure in RAID or failover setups.
• ​​UCS C240 M7-Specific Design​​: Precision-engineered length and connectors ensure seamless integration with the server’s internal layout.

Addressing Key User Concerns

“Which drive types does this cable support?”

The CBL-SAS24-C240M7= is compatible with ​​SAS3 and SATA III drives​​ installed in the UCS C240 M7’s front bays. For NVMe storage, use Cisco’s ​​CBL-NVMe-240M7=​​ instead.

“Can I reuse SAS cables from older UCS C240 models?”

​​No.​​ The C240 M7’s revised backplane and controller (e.g., Broadcom SAS3816) require the CBL-SAS24-C240M7=’s updated pinout. Older cables (e.g., M5/M6 variants) risk drive detection errors or degraded speeds.

“Is this cable needed for minimum drive configurations?”

Yes. Even with a single drive bay populated, the CBL-SAS24-C240M7= is mandatory to establish communication between the SAS controller and backplane.

Procuring Authentic CBL-SAS24-C240M7= Cables

Genuine Cisco cables undergo rigorous testing for signal integrity and EMI resistance. Purchase from authorized suppliers like ​​itmall.sale​​ to avoid counterfeit products that compromise data reliability.

Practical Deployment Insights

In a recent hyperscale backup solution deployment, replacing a third-party SAS cable with the CBL-SAS24-C240M7= resolved chronic timeout errors during parallel write operations. While invisible to end-users, this cable’s ​​24-lane stability​​ under 90%+ storage load proves its worth. For teams managing UCS C240 M7 storage arrays, skipping this component is akin to building a sports car with bicycle chains—possible, but catastrophically shortsighted.
