eshinreal 2-Port SFF-8088 to SFF-8087 Expansion Card

SKU CH-C9N5-Z99FG

Connects two external Mini-SAS 8088 ports to two internal 8087 ports for 6 Gbps SAS 2.0 and SATA III storage expansion

  • TypeController Card
  • Connect external enclosures via dual SFF-8088 ports
  • Transfer data at 6Gbps per port with SAS 2.0
  • Passive design ensures reliable signal conversion
  • Add JBOD or DAS storage to rack servers
  • Works with SAS 1.0 and SATA II devices

Dual-Port Mini-SAS Adapter

The eshinreal card converts two external SFF-8088 connectors to two internal SFF-8087 connectors. It lets administrators attach external SAS or SATA enclosures to an internal RAID or HBA controller. The passive design requires no extra power and adds no active latency. It suits server, NAS and JBOD expansion tasks.

SAS 2.0 and SATA III Speed Limits

Each port runs at up to 6 Gbps under the SAS 2.0 or SATA III specifications. The card is backward compatible with SAS 1.0 and SATA II devices, which will operate at their native lower rates. Total throughput depends on the host controller and the number of drives attached. Cable length and quality also affect reliable signal integrity at the maximum rate.

Verify Controller and Cabling First

Confirm that your RAID or HBA card presents SFF-8087 ports and supports the desired SAS or SATA protocol. Ensure you have SFF-8088 cables for the external side and SFF-8087 cables for the internal side. Hot-plug capability works only when the host controller and enclosure firmware both permit it. Buyers needing active signal conditioning for long cable runs should check the specific model variant before ordering.

Questions about this item

Should I pick a passive or active version of this SFF-8088 to SFF-8087 card?

This model is a passive design with no active components, so it relies on the host controller signal quality and suits shorter internal-to-external runs.

What does the 6Gbps per port rating deliver when the card is installed?

Each port runs at SAS 2.0 or SATA III 6Gbps, so the actual throughput depends on the attached drives and the host controller behind the card.

Which interface standard does the SFF-8088 side use and what speed does it cap at?

The external SFF-8088 ports follow the SAS 2.0 standard, limiting each lane to 6Gbps and maintaining backward compatibility with SAS 1.0 and SATA II.
