Key Product Advantages
This StarTech.com network adapter provides several technical advantages for server networking applications. The dual-port design enables network teaming for increased throughput or failover configurations, while the inclusion of both standard and low-profile brackets ensures compatibility with diverse server form factors.
Advanced Feature Support
The adapter supports Microsoft NDIS5 checksum offload for IP, TCP, and UDP protocols, reducing CPU overhead during network operations. Large send offload capabilities optimize performance for large data transfers, while Wake-on-LAN support enables remote system management.
- 9K Jumbo Frame support
- Pair swap/polarity/skew correction
- Environmental RoHS compliance
Reliable Server Connectivity
Designed specifically for server environments, this adapter maintains stable connections under continuous operation. The twisted-pair media support ensures compatibility with existing network infrastructure, while the compact form factor fits standard PCIe slots without obstructing adjacent components.
Deployment / Use Cases
The ST1000SPEXD4 adapter serves multiple deployment scenarios in server environments. Primary applications include adding supplemental network interfaces to servers that require separate connections for management, data, or backup networks. The dual-port configuration enables link aggregation for increased bandwidth or active-passive failover setups.
This adapter proves particularly valuable in virtualization hosts where separate network interfaces benefit different virtual machines or network functions. Small business servers can utilize the additional ports to segregate internal and external traffic, while development servers benefit from isolated network segments for testing environments. The low-profile bracket inclusion makes this adapter suitable for space-constrained 1U and 2U server racks where full-height cards cannot be accommodated.
Server Network Expansion
Ideal for servers requiring additional Ethernet ports beyond motherboard capabilities. The PCIe x1 interface provides sufficient bandwidth for Gigabit networking while conserving larger PCIe slots for other expansion cards.
Network Segmentation
Use one port for production traffic and the second for backup or management networks. The adapter's VLAN support enables logical network separation without requiring additional physical hardware.
Physical Profile
Measuring 4.70 inches in height, 0.70 inches in width, and 3.60 inches in depth (119.38 × 17.78 × 91.44 mm), this network adapter maintains a compact footprint suitable for most server chassis. The plug-in card form factor installs directly into available PCI Express x1 slots, with the lightweight 1.90-ounce (53.86 g) design minimizing stress on the motherboard. The included low-profile bracket enables installation in slim server enclosures, while the standard bracket accommodates full-height chassis configurations.
