eshinreal 2-Port SFF-8644 to SFF-8643 Converter Expansion Card

SKU CH-GPHP-W8W92

Converts two external SFF-8644 ports to internal SFF-8643 connections at 12Gbps SAS 3.0 speed with passive plug-and-play operation

  • TypeController Card
  • Connect external storage via dual SFF-8644 ports
  • Achieve 12Gbps throughput per port with SAS 3.0
  • Operate without extra power using passive design
  • Enable hot-swap support for enterprise deployments
  • Fit 1U and 2U servers with low-profile bracket

Dual-Port SAS Adapter

The eshinreal converter card bridges external SFF-8644 Mini-SAS HD connections to internal SFF-8643 Mini-SAS HD backplanes. It suits server administrators and storage engineers who need to link JBOD enclosures or expansion chassis directly to internal RAID controllers or HBAs. The passive design operates without additional power, making it a straightforward addition to existing 1U or 2U rack builds.

Bracket Options and Signal Integrity

Two mounting brackets ship with the card, allowing installation in either low-profile or full-height slots without tools. Metal-shielded connectors protect the 12Gbps signal path from EMI and RFI interference, preserving data integrity across the link. LED activity indicators on the bracket provide visual confirmation of drive status and hot-swap events when the host hardware supports them.

Compatibility Checklist

Verify that your external enclosure uses SFF-8644 ports and that your internal controller or backplane presents SFF-8643 connectors before ordering. The card is passive, so it relies entirely on the host HBA or RAID card to drive the link at 12Gbps SAS 3.0 or fall back to 6Gbps SAS 2.0 and SATA III speeds. Ensure your operating environment supports hot-swap if that feature is required.

Preguntas sobre este artículo

Will the passive SFF-8644 to SFF-8643 converter card need firmware updates or active component replacement over time?

The passive design has no active components or firmware, so no firmware updates or component replacements are required during its service life.

What bandwidth limit appears first when both SFF-8644 ports run sustained 12Gbps SAS 3.0 traffic?

Each port is rated for 12Gbps SAS 3.0; the per-port 12Gbps ceiling is the first limit reached under sustained full-speed use.

How much heat or noise does the card add when installed in a 1U server running all day?

The passive card draws no power and has no fan, so it adds negligible heat and zero audible noise during continuous operation.
