The SFF-8482 SAS cable is specifically designed for connecting SAS hard drives to compatible controllers or backplanes. Here’s a breakdown of the key features and uses of this type of cable:
Features:
- Connector Type:
- SFF-8482 (Drive End): This connector is used to connect directly to SAS hard drives. It combines both data and power in a single interface.
- SATA or SAS Controller End: The other end of the cable typically has standard connectors like SATA or SAS (SFF-8087 or SFF-8643) to connect to the controller or motherboard.
- Compatibility:
- Designed for SAS drives but backward-compatible with SATA drives (when used with a controller that supports SATA drives).
- Power Support:
- The SFF-8482 connector has an integrated power supply pin, often requiring an external power source or adapter cable for power delivery.
- Cable Length:
- Available in various lengths, typically ranging from 0.5m to 2m.
- Durability:
- Built to handle enterprise-level environments with robust shielding to prevent signal interference.
Uses:
- Server Applications: Used in data centers for connecting SAS drives in RAID arrays or storage enclosures.
- Workstations: For high-performance applications that need SAS drive capabilities.
- External Enclosures: Often used to connect SAS drives in external storage units to the main system.
Example Setup:
- Plug the SFF-8482 connector into the SAS drive.
- Connect the other end of the cable (e.g., SATA or SAS controller connector) to the corresponding controller on the motherboard or RAID card.
- Ensure the drive has adequate power, either through the SFF-8482 cable or a separate power supply adapter.
If you’re looking to purchase or set up such a cable, ensure that your controller and drives are compatible with SAS standards and that the cable length meets your installation requirements.
