Fervit Dual SFF-8612 Oculink to Dual E1.S Adapter

SKU CH-1190-XXBKQ

Connects two E1.S SSDs to dual OCuLink ports with PCIe 4.0/5.0 support up to 64Gbps

  • Dual PCIe 4x channels connect two SSDs per adapter
  • Supports E1.S drives at 9.5, 15 and 25 mm heights
  • Transfers PCIe 4.0 and 5.0 signals at up to 64 Gbps
  • EDSFF form factor improves thermal and power management
  • OCuLink SFF-8611 and SFF-8612 connectors fit internal or external use

Dual OCuLink to E1.S adapter for servers and IoT

This Fervit adapter converts two Gen-Z E1.S SSDs into OCuLink PCIe 4x connections for servers, data centres and IoT devices. It uses dual PCIe 4x channels so each OCuLink port drives one SSD. The board mounts internally through SFF-8611 or SFF-8612 interfaces and supports PCIe 4.0 and 5.0 signalling up to 64Gbps.

Suits builders adding E1.S storage to OCuLink

It accepts 9.5mm, 15mm and 25mm heat-sink-equipped E1.S drives such as PM9A3, PM9D3 and P5801X models. The OCuLink 4x connectors also carry SAS-4 24Gbps traffic for mixed environments. Buyers who need M.2 or U.2 drive support, or who require more than two SSD slots, should look at a different carrier.

Handles two E1.S SSDs with Gen4/Gen5 headroom

Each channel delivers full PCIe 4.0 or 5.0 bandwidth so high-performance SSDs run without bottleneck. The 64Gbps ceiling matches current Gen4 and Gen5 devices, while the EDSFF form factor improves thermal and power management over legacy layouts. Capacity scales with the chosen E1.S modules; the adapter itself adds no storage limit.

Questions about this item

What host connector does the adapter need on the server side?

The adapter plugs into an OCuLink SFF-8611 or SFF-8612 PCIe 4x host port on the server or backplane.

Will the adapter work with a PCIe 3.0 host link?

Yes, the OCuLink 4x connectors support PCIe Gen3, Gen4 and Gen5, so a Gen3 host will operate at its native speed.

How can I confirm the adapter is passing data at full speed after installation?

Verify the link negotiates PCIe 4.0 or 5.0 and measure throughput up to 64Gbps with a storage benchmark on the attached E1.S SSDs.
