StarTech.com P041GI-NETWORK-CARD 4-Port GbE SFP PCIe 2.0 x2 Network Card

Network bottlenecks can cripple your server or workstation, especially when you need to connect multiple high-speed links. The StarTech.com P041GI-NETWORK-CARD 4-Port GbE SFP PCIe 2.0 x2 Network Card lets you add four gigabit SFP or Direct Attach modules, turning a single PCIe slot into a versatile, high-performance network hub that keeps your data flowing smoothly.

StarTech.com P041GI-NETWORK-CARD 4-Port GbE SFP PCIe 2.0 x2 Network Card - a reliable solution for crowded network environments

When you run several virtual machines, storage arrays, or remote sites, a single Ethernet port often becomes a choke point. This can lead to latency spikes, dropped packets and higher CPU load, all of which affect productivity and service quality. The StarTech.com P041GI-NETWORK-CARD 4-Port GbE SFP PCIe 2.0 x2 Network Card eliminates the bottleneck by providing four independent gigabit SFP ports, each capable of handling its own traffic stream. With Intel’s proven I350 chipset, low latency and minimal CPU utilisation are built in, while features such as VMDq, SR-IOV and VT-c improve virtual machine networking and reduce overhead. The card also supports PXE boot for easy OS deployment and 9K jumbo frames for efficient large-packet transfers, making it a clear answer to demanding network workloads.

Usages of StarTech.com P041GI-NETWORK-CARD 4-Port GbE SFP PCIe 2.0 x2 Network Card

Ideal for a range of professional settings:

• Adding redundant gigabit links to a virtualization host running VMware ESXi or Hyper-V.
• Connecting a storage server to multiple fibre channels for fast backup and replication.
• Upgrading a workstation that requires both copper and fibre connections for testing environments.
• Providing separate VLANs for guest, management and production traffic on a single server.
• Enabling PXE boot across a fleet of thin clients in a corporate lab.
