Product Information
Full details
This guide is for system builders and IT professionals seeking to connect SATA drives to SAS controllers. The Microchip Technology Adaptec I-HDmSAS-4SATA-SB-.8M cable offers a reliable 0.8-meter solution for internal system builds. A key benefit is its direct SAS HD to SATA fan-out configuration, enabling simplified storage expansion. However, it's important to note that this cable is specifically designed for adapter-based connections and may not be suitable for all backplane configurations.

FAQs
Can I connect SAS drives with this cable?
No, this cable is specifically designed to connect SATA drives to a SAS adapter. It is not compatible with SAS drives.
What is the maximum data transfer rate?
The cable supports a maximum data transfer rate of 6 Gbit/s per SATA channel.
What does 'sideband signals' mean in this context?
Sideband signals are communication channels used for management and control functions beyond basic data transfer, such as SES (SCSI Enclosure Services) for enclosure management.
Is this cable compatible with all SAS controllers?
It is primarily designed and tested for Microsemi Adaptec 7 Series, 7Q Series, 7H Series, and 7He Series adapters. Compatibility with other brands or series may vary.
Can I use this cable for external connections?
No, this is an internal cable designed for use within a computer chassis. The connectors are intended for internal ports.
What is the connector type on the SAS side?
The SAS connector is an internal Mini-SAS HD x4 (SFF-8643) connector.
What is the connector type on the drive side?
The drive side consists of four individual SATA connectors.
Troubleshooting
Drives not detected by the system.
Verify that both ends of the cable are securely connected. Ensure the SAS adapter is properly seated and recognized. Check SATA power connections to the drives. Confirm compatibility with your specific SAS controller.
Intermittent connection or data errors.
Inspect the cable for any visible damage. Reseat the cable at both the adapter and drive ends. Ensure the cable is not bent sharply or stressed. Try a different SFF-8643 port on the adapter if available.
Performance is lower than expected.
Confirm that the connected drives are SATA and not SAS. Ensure the SAS adapter supports 6 Gbit/s. Check drive health and system resource utilization.
Pros and Cons
Pros
- Facilitates easy connection of multiple SATA drives to a single SAS port.
- Provides essential sideband signaling for robust data management.
- Standard 0.8m length suitable for most internal system builds.
- Reliable connectivity for SAS 7/7Q/7H/7He adapter series.
- High-speed 6 Gbit/s performance per channel.
Cons
- Limited to 0.8 meters, which might be too short for larger chassis.
- Adapter-based design may not be compatible with all SAS/SATA backplanes.
- Only supports SATA drives; not compatible with SAS drives directly.
- Requires a SAS controller with an SFF-8643 port.
- Specific to Microsemi Adaptec Series 7 controllers for guaranteed compatibility.
Setup, Compatibility & Care
Setup:
- Ensure your system is powered off and grounded.
- Connect the SFF-8643 end of the cable to the corresponding port on your SAS adapter (e.g., Microsemi Adaptec Series 7).
- Connect the four individual SATA ends of the cable to your SATA drives.
- Route the cable neatly within your system to avoid obstruction of airflow.
- Power on your system and verify drive recognition in the BIOS or operating system.
Compatibility:
- SAS Adapters: Primarily designed for Microsemi Adaptec 7 Series, 7Q Series, 7H Series, and 7He Series adapters.
- SATA Devices: Compatible with all standard SATA hard drives and SSDs.
- Backplanes: Use is recommended for adapter-based connections; verify compatibility with specific backplane designs.
Care:
- Handle connectors gently to avoid damage.
- Keep cables away from sharp edges or excessive heat sources.
- Periodically check connections for security and cleanliness. Clean with a dry, lint-free cloth if necessary.
