Synology E10G21-F2 Dual-Port 10GbE SFP+ Adapter
Dual-port 10GbE SFP+ adapter for qualified Synology NAS and server platforms. Record applies to the exact SKU named here; verify the physical label and revision.
IDENTIFICATION: Product label: E10G21-F2. Link rates are nominal negotiated signaling rates, not measured throughput.
Specifications and OS compatibility
| Catalog subcategory | Ethernet adapters |
|---|---|
| Exact product SKU | E10G21-F2 |
| Controller | Intel Ethernet Controller X710 family, as used by this adapter; Synology platform/driver qualification is model-specific. |
| Bus, lane and port interface | PCI Express 3.0 x8 card; x4 link operation supported; two SFP+ cages. |
| Ports and media | 2 port(s); 10GbE SFP+ interface. |
| Nominal line rate (not measured) | Two independent 10 Gb/s SFP+ Ethernet links; 20 Gb/s aggregate nominal line rate. |
| Operating systems and drivers | Synology documents DSM 6.2.3-25426 or later on supported systems; SR-IOV requires later DSM and compatible hardware. Generic Linux i40e support is not equivalent to Synology NAS qualification. |
| Compatibility notes | Check the Synology PCIe card compatibility list for the exact NAS/server model. SFP+ transceiver/DAC support is media-specific; the physical x8 connector can operate at x4 as documented. No payload benchmark is claimed. |
| Measured throughput | No physical specimen benchmark is claimed. A meaningful result must identify host, peer, link partner, media, driver/firmware, traffic pattern, test tool and duration. |
Model and revision notes
Check the Synology PCIe card compatibility list for the exact NAS/server model. SFP+ transceiver/DAC support is media-specific; the physical x8 connector can operate at x4 as documented. No payload benchmark is claimed.
Confirm exact card revision, device ID, transceiver/cable type, host firmware, bracket and driver build before installation. Use vendor qualification data for server/NAS deployment.
Preservation and measurement notes
Record card revision, controller marking and driver/firmware versions. Power down before installation; handle by edges and store in ESD shielding.
No measured throughput is represented by the nominal line rate. Record peer, media, negotiated rate, traffic pattern, test tool and duration for any future benchmark.
