Adapter Icybox MB308A — 2x SlimSAS 8i to PCIe with signal redriver

Icybox MB308A is an adapter that converts two SlimSAS 8i connections to a single PCIe interface and incorporates a built-in signal redriver. The adapter is designed to enable integration of dual SlimSAS devices into systems that expose a PCIe slot, preserving signal quality for high-speed SAS links and facilitating stable connection between storage backplanes or host controllers and the system motherboard.

Advantages

The adapter maintains signal integrity for high-frequency data transfers by using an integrated signal redriver, which compensates for attenuation and crosstalk on longer traces or through connectors. Its dual SlimSAS 8i to PCIe conversion allows two independent SlimSAS links to be presented over a PCIe interface, simplifying installation in servers, workstations and storage enclosures. The compact design is compatible with common PCIe slot form factors and reduces the need for custom cabling or additional active components.

Suitable for

• Integrating dual SlimSAS-equipped drive backplanes into a PCIe-enabled server or workstation
• Expanding storage connectivity in small form factor systems using existing PCIe ports
• Testing or developing SAS storage controllers and bridge cards in lab environments
• Replacing custom adapters where improved signal conditioning is required

Key specifications

• Interface conversion: two SlimSAS 8i inputs to one PCIe output
• Signal conditioning: integrated redriver for improved high-speed signal integrity
• Supported link types: high-speed SAS links over SlimSAS 8i cabling
• Form factor: adapter designed for installation into a standard internal PCIe slot
• Compatibility: intended for use with server, workstation and storage devices supporting SlimSAS and PCIe interconnects

How to use

Install the adapter into an available internal PCIe slot on the host system according to the system manufacturer's installation procedures. Connect the SlimSAS 8i cables from the storage backplane or SlimSAS devices to the adapter's two SlimSAS ports, ensuring secure, fully seated connections. After hardware installation, verify that the host firmware and operating system detect the connected storage devices and load any required drivers for the host controller or bridge hardware. If necessary, consult the system or controller documentation for device initialization and RAID configuration steps.

Usage recommendations

Use high-quality SlimSAS 8i cables and maintain recommended routing and minimal cable lengths where possible to achieve optimal signal performance. Ensure the host motherboard and controller firmware are up to date to maximize compatibility. When installing in densely populated server chassis, verify airflow and clearance around the adapter to avoid thermal or mechanical interference.
