10GbE Intel X520-DA1 82599ES Chipset Ethernet Converged Network Adapter NIC Single SFP Port PCI Express 2.0 X8 Intel X520-DA2 (2xRJ45 ports)

l'ho installata su pfsense per collegarlo ad uno switch mikrotik in 10G. Il sistema l'ha visto senza nessun problema e le performance sono ottime. La consiglio per la sua facilità d'uso e per il prezzo.

Worked perfectly how I needed didn't even need a driver

Arrived within estimate and product as described.For those interested, these seem to ship with SFP vendor locking disabled, so non-Intel SFP should work.

Got this for my Proxmox machine; It works fine with a Windows 2019 VM but TrueNAS Scale and Ubuntu VMs not so much – they get a valid IP via dhcp but no network connectivity so I think there are issues with Linux drivers or kernel. I just ordered a SolarFlare SFN6122F which TrueNAS reports works (see TrueNAS resources: 10 Gig Networking Primer), if it does, then I’ll be returning this.‘lspci -vvxnn’ below:Ethernet controller [0200]: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection [8086:10fb] (rev 01)Subsystem: Beijing Sinead Technology Co., Ltd. 82599ES 10-Gigabit SFI/SFP+ Network Connection [1dcf:030a]Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-Latency: 0, Cache Line Size: 64 bytesInterrupt: pin A routed to IRQ 16IOMMU group: 5Region 0: Memory at 84180000 (32-bit, non-prefetchable) [size=512K]Region 2: I/O ports at 3020 [size=32]Region 3: Memory at 84204000 (32-bit, non-prefetchable) [size=16K]Expansion ROM at 84100000 [disabled] [size=512K]Capabilities: [40] Power Management version 3Flags: PMEClk- DSI+ D1- D2- AuxCurrent=0mA PME(D0+,D1-,D2-,D3hot+,D3cold-)Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=1 PME-Capabilities: [50] MSI: Enable- Count=1/1 Maskable+ 64bit+Address: 0000000000000000 Data: 0000Masking: 00000000 Pending: 00000000Capabilities: [70] MSI-X: Enable+ Count=64 Masked-Vector table: BAR=3 offset=00000000PBA: BAR=3 offset=00002000Capabilities: [a0] Express (v2) Endpoint, MSI 00DevCap: MaxPayload 512 bytes, PhantFunc 0, Latency L0s <512ns, L1 <64usExtTag- AttnBtn- AttnInd- PwrInd- RBE+ FLReset+ SlotPowerLimit 0WDevCtl: CorrErr+ NonFatalErr+ FatalErr+ UnsupReq+RlxdOrd+ ExtTag- PhantFunc- AuxPwr- NoSnoop+ FLReset-MaxPayload 256 bytes, MaxReadReq 512 bytesDevSta: CorrErr+ NonFatalErr- FatalErr- UnsupReq+ AuxPwr- TransPend-LnkCap: Port #0, Speed 5GT/s, Width x8, ASPM L0s, Exit Latency L0s unlimitedClockPM- Surprise- LLActRep- BwNot- ASPMOptComp-LnkCtl: ASPM Disabled; RCB 64 bytes, Disabled- CommClk+ExtSynch- ClockPM- AutWidDis- BWInt- AutBWInt-LnkSta: Speed 5GT/s, Width x4 (downgraded)TrErr- Train- SlotClk+ DLActive- BWMgmt- ABWMgmt-DevCap2: Completion Timeout: Range ABCD, TimeoutDis+ NROPrPrP- LTR-10BitTagComp- 10BitTagReq- OBFF Not Supported, ExtFmt- EETLPPrefix-EmergencyPowerReduction Not Supported, EmergencyPowerReductionInit-FRS- TPHComp- ExtTPHComp-AtomicOpsCap: 32bit- 64bit- 128bitCAS-DevCtl2: Completion Timeout: 50us to 50ms, TimeoutDis- LTR- 10BitTagReq- OBFF Disabled,AtomicOpsCtl: ReqEn-LnkCtl2: Target Link Speed: 5GT/s, EnterCompliance- SpeedDis-Transmit Margin: Normal Operating Range, EnterModifiedCompliance- ComplianceSOS-Compliance Preset/De-emphasis: -6dB de-emphasis, 0dB preshootLnkSta2: Current De-emphasis Level: -6dB, EqualizationComplete- EqualizationPhase1-EqualizationPhase2- EqualizationPhase3- LinkEqualizationRequest-Retimer- 2Retimers- CrosslinkRes: unsupportedCapabilities: [e0] Vital Product DataUnknown small resource type 06, will not decode more.Capabilities: [100 v1] Advanced Error ReportingUESta: DLP- SDES- TLP- FCP- CmpltTO- CmpltAbrt- UnxCmplt- RxOF- MalfTLP- ECRC- UnsupReq- ACSViol-UEMsk: DLP- SDES- TLP- FCP- CmpltTO- CmpltAbrt- UnxCmplt- RxOF- MalfTLP- ECRC- UnsupReq- ACSViol-UESvrt: DLP+ SDES- TLP- FCP+ CmpltTO- CmpltAbrt- UnxCmplt- RxOF+ MalfTLP+ ECRC- UnsupReq- ACSViol-CESta: RxErr- BadTLP- BadDLLP- Rollover- Timeout- AdvNonFatalErr+CEMsk: RxErr- BadTLP- BadDLLP- Rollover- Timeout- AdvNonFatalErr+AERCap: First Error Pointer: 00, ECRCGenCap+ ECRCGenEn- ECRCChkCap+ ECRCChkEn-MultHdrRecCap- MultHdrRecEn- TLPPfxPres- HdrLogCap-HeaderLog: 00000000 00000000 00000000 00000000Capabilities: [140 v1] Device Serial Number xxxxxxxxxxxCapabilities: [150 v1] Alternative Routing-ID Interpretation (ARI)ARICap: MFVC- ACS-, Next Function: 1ARICtl: MFVC- ACS-, Function Group: 0Capabilities: [160 v1] Single Root I/O Virtualization (SR-IOV)IOVCap: Migration- 10BitTagReq- Interrupt Message Number: 000IOVCtl: Enable- Migration- Interrupt- MSE- ARIHierarchy+ 10BitTagReq-IOVSta: Migration-Initial VFs: 64, Total VFs: 64, Number of VFs: 0, Function Dependency Link: 00VF offset: 128, stride: 2, Device ID: 10edSupported Page Size: 00000553, System Page Size: 00000001Region 0: Memory at 00000060e0300000 (64-bit, prefetchable)Region 3: Memory at 00000060e0200000 (64-bit, prefetchable)VF Migration: offset: 00000000, BIR: 0Kernel driver in use: ixgbeKernel modules: ixgbe

This card works OK, but it's not stable on windows 11 pro, I would fix the drivers, and updates would break them.For windows 11, stay away.
