Eladó a címben szereplő 4 portot gigabites hálózati vezérlő.
2 darab van belőle, az ár 1 darabra vonatkozik. Mindegyik bontatlan, ESD zacskóban.

- Supports interrupt moderation to deliver increased performance while significantly reducing central processing unit (CPU) utilization
- Allows quad-port operation in x4, x8, x16 slots, and each port operates without interfering with the other
- Each port operates without interfering with the other
- Auto-negotiation, full-duplex (half-duplex available for 10/100)
- Integrated media access control (MAC) and physical layer (PHY)
- Supports Fast EtherChannel (FEC) and Gigabit EtherChannel (GEC) when used with capable switch
- Supports IEEE 802.3ad Link Aggregation control protocol when used with capable switch
- IEEE 802.1Q VLANs, IEEE 802.3 (z, ab, u, x) flow control support, IEEE 802.1p
- TCP checksum offload -- transmission control protocol (TCP), Internet Protocol (IP) for IPv4
- TCP Segmentation Offload (TSO) / Large Send Offload (LSO)
- Bus width x4 lane; operable in x4, x8, or x16 slots
- Bus speed (x4, encoded rate) 10 Gbps unidirectional and 20 Gbps bidirectional
- EEPROM SPI and single EEPROM support
- Interrupt levels INTA and MSI (requires system and software support for MSI)
- IEEE 802.3ab
- Hardware certifications FCC B, UL, CE, VCCI, BSMI, CTICK, MIC
- Four RJ-45 connectors
- LEDs on each port identifying speed and link activity
- Compliant with European Union Directive 2002/95/EC on the Restriction of the Use of Certain Hazardous Substances in Electrical and Electronic Equipment

Kiváló kártya otthoni szerverbe, home-lab építéséhez, pfSense boxhoz, VMware host-hoz (4 port teaming = 4Gbps).
Két kártya esetén: 8db gigabites port = 8Gbps teaming / multipath. Egy menedzselhető switch segítségével olcsón kiépíthető 10Ge -hez közeli teljesítmény, töredék áron.

Személyesen Budapesten az Örs Vezér terén tudom odaadni, de előreutalás után postázom is (pl.: Foxpost, MPL csomagautomata, stb...).
