What Is the CBL-SAS24-240M6= and How Does It Optimize Storage Connectivity in Cisco UCS C240 M6 Servers?

Technical Overview of the CBL-SAS24-240M6=

The ​​CBL-SAS24-240M6=​​ is a ​​24-lane SAS 12Gb/s cable​​ designed for the ​​Cisco UCS C240 M6​​ rack server. It connects the server’s ​​SAS RAID controller​​ to the ​​drive backplane​​, enabling high-speed data transfer between storage drives and the host system. With a ​​2.4-meter length​​, it supports flexible configurations in dense rack environments.

Key Applications in Enterprise Storage

​​Why is this cable critical for UCS C240 M6 deployments?​​

• ​​High-Density Storage​​: Supports up to ​​24 SAS/SATA drives​​, ideal for databases, virtualization, or big data workloads.
• ​​RAID Performance​​: Ensures full bandwidth for hardware RAID controllers like the ​​Cisco 12G Modular RAID Controller​​, minimizing latency during parity calculations.
• ​​Hot-Swap Capability​​: Facilitates drive replacements without downtime, crucial for 24/7 operations.

Compatibility and Performance Specifications

​​Which components require this cable?​​

• ​​UCS C240 M6 Server​​: Requires the cable to link the ​​SAS expander card​​ (e.g., ​​Cisco 12G SAS Expander​​) to the drive backplane.
• ​​Drive Types​​: Compatible with ​​12G SAS HDDs/SSDs​​ and ​​6G SATA SSDs​​.

​​Critical technical details​​:

• ​​Data rate​​: 12Gb/s per lane, aggregating to ​​288Gb/s total bandwidth​​.
• ​​Maximum drive support​​: 24 x 2.5-inch or 12 x 3.5-inch drives (with optional sleds).
• ​​Cable shielding​​: Foil and braid shielding to reduce electromagnetic interference (EMI) in multi-server racks.

Installation and Maintenance Best Practices

​​What pitfalls degrade storage performance?​​

• ​​Incorrect Routing​​: Avoid sharp bends; maintain a ​​50mm minimum bend radius​​ to prevent signal loss.
• ​​Firmware Mismatches​​: Ensure RAID controller and expander firmware are updated to ​​Cisco-approved versions​​.
• ​​Drive Mixing​​: Avoid combining SAS and SATA drives on the same controller port without proper zoning.

Sourcing Authentic CBL-SAS24-240M6= Cables

For uninterrupted storage performance, procure the CBL-SAS24-240M6= exclusively through certified suppliers like “itmall.sale”. Third-party cables often lack proper impedance matching, risking data corruption or dropped drives in RAID arrays.

Perspective on Storage Infrastructure Reliability

The CBL-SAS24-240M6= highlights a lesson learned from countless data center audits: storage bottlenecks often trace back to overlooked cabling. In mission-critical environments, where every I/O delay impacts revenue, investing in purpose-built cables like this isn’t optional—it’s the bedrock of predictable, high-performance storage. Cutting corners here risks more than hardware; it jeopardizes business continuity.
