22 Pin Male to 29 Pin Female SAS Adapter

The SFF-8482 SAS 22-Pin to 7-Pin Data + 15-Pin Power SATA Hard Disk Drive Adapter is a versatile adapter that enables the connection of a Serial Attached SCSI (SAS) drive to a standard SATA host controller, allowing the use of SAS hard drives in systems that primarily support SATA connections.

Key Features:

• SFF-8482 SAS 22-Pin Connector: The SFF-8482 is a 22-pin connector designed for SAS (Serial Attached SCSI) hard drives. It consists of a 7-pin data connector and a 15-pin power connector combined into a single 22-pin interface. This interface is primarily used in enterprise-level storage solutions, servers, and workstations where high-performance SAS drives are deployed. SAS drives offer better performance, reliability, and enhanced error correction compared to standard SATA drives.

• 7-Pin SATA Data Connector: This adapter provides a standard 7-pin SATA data connector that links to a SATA host controller, such as a motherboard, RAID controller, or a SATA expansion card. The SATA data connector ensures high-speed data transfer between the SAS drive and the host system.

• 15-Pin SATA Power Connector: The adapter also features a standard 15-pin SATA power connector. This provides power to the SAS drive using a typical SATA power source, such as from the system's power supply unit (PSU).

Technical Specifications:

1. Connectors:

   • Input: SFF-8482 SAS 22-pin male connector (7 data pins + 15 power pins).
   • Output: Standard 7-pin SATA data connector and 15-pin SATA power connector.

2. Functionality:

   • SAS Drive to SATA Host Connection: This adapter allows SAS hard drives to be connected to a SATA host controller. It provides the necessary conversion to allow the SAS drive to interface with a system that only has SATA ports.
   • Power and Data Transmission: The adapter manages both data transfer through the 7-pin SATA data connection and power delivery via the 15-pin SATA power connector.

3. Compatibility:

   • The adapter is designed for SAS hard drives that use the SFF-8482 connector, typically found in enterprise-grade 3.5-inch and 2.5-inch drives.
   • It is compatible with SATA I, II, and III hosts, supporting data transfer speeds up to 6 Gb/s, depending on the host controller and drive capability.

4. Build and Durability:

   • The adapter is built with reliable and sturdy materials to ensure secure connections and consistent performance during use. The connectors are designed to fit securely and maintain stable power and data connections to avoid interruptions during operation.

5. SAS Drive Support:

   • While this adapter allows SAS drives to connect to SATA systems, it is important to note that SAS drives have full backward compatibility with SATA, but SATA controllers cannot utilize the dual-port capabilities of SAS drives. As such, the adapter will enable single-port operation of the SAS drive.

Use Cases:

• Legacy System Integration: This adapter is ideal for systems that primarily support SATA drives but require the performance and reliability of SAS drives, making it useful in server migrations or upgrades.
• Data Recovery: Useful in data recovery scenarios where data needs to be extracted from SAS drives using a system equipped with only SATA interfaces.
• Custom Builds: Enables users to utilize enterprise-level SAS hard drives in desktop or small server environments where only SATA interfaces are available.

Limitations:

• Single-Port Operation: While SAS drives offer dual-port operation for redundancy and failover in enterprise environments, this adapter only supports single-port operation since it connects to a single SATA host controller.
• Host Compatibility: This adapter allows the connection of SAS drives to a SATA host controller, but not vice versa. SATA drives cannot be connected to SAS host controllers using this adapter.
