Dual 10 Gbps SFP+ ports
The Dell X520-DA2 adds two 10 Gbps SFP+ ports over a PCI Express 2.0 x8 slot. It supports fiber or direct-attach copper cables for high-speed LAN or storage links. Compatible with Windows, Linux, VMware ESXi and FreeBSD on desktop or server platforms.
Replaces single-port or 1 GbE adapters
Moving from a single 10 GbE port or a 1 GbE NIC to this dual-port card doubles bandwidth and adds link aggregation or failover. The upgrade is worth it when a server or workstation needs redundant 10 Gbps paths or concurrent client and storage traffic.
Handles two concurrent 10 Gbps streams
Each port delivers up to 10 Gbps, so the card comfortably saturates dual 10 GbE links for backup, virtualisation or high-throughput storage. Headroom ends when aggregate traffic exceeds 20 Gbps or when the host PCIe 2.0 x8 bus becomes the bottleneck.

이 상품에 대한 질문
Will the 6.6 in by 2.7 in card fit in a low-profile bracket or does it need a full-height slot?
The adapter measures 6.6 in by 2.7 in and requires a standard full-height PCI-E 2.0 x8 or larger slot; no low-profile bracket is included.
Which SFP+ modules or direct-attach cables work with the two 10 Gbps ports?
Insert any SFP+ 10 Gb fiber transceiver or SFP+ direct-attach cable into each port; the card supports IEEE 802.3ae, 802.3ap and 802.3an links at up to 10 Gbps per port.
Do the SFP+ cages or the PCI-E x8 edge connector need periodic cleaning or replacement?
The SFP+ cages and PCI-E x8 edge connector are passive; clean the optical interfaces only if link errors appear, otherwise no scheduled maintenance is required.
