eshinreal 4-Port SFF-8087/8088 SAS/SATA Expansion Card (SAS2X36)

4-Port SAS/SATA Expansion Card

The eshinreal add-on card provides four SAS 2.0 ports running at 6 Gbps each, split between one internal SFF-8087 connector and one external SFF-8088 connector. It targets server builders who need to attach additional SAS or SATA drives without a dedicated RAID controller. The SAS2X36 expander chip handles drive enumeration so the host sees every attached device.

Sustained throughput via PCIe 2.0 x4

The card sits on a PCIe 2.0 x4 link that delivers 2 Gbps per lane, setting a ceiling for continuous data movement across all 24 supported drives. Because the SAS2X36 operates as an expander rather than a RAID engine, every drive appears independently to the operating system and the host controller manages the workload. This architecture suits backup targets and archival arrays where steady streaming matters more than burst speed.

Low-profile brackets for 1U and 2U servers

Both full-height and half-height brackets ship in the box so the card fits dense rack chassis without blocking adjacent slots. The SAS2X36 expander draws modest power from the PCIe slot and runs passively, relying on chassis airflow rather than an onboard fan. No auxiliary power connector is present, keeping cable routing simple in tightly packed enclosures.
