Deployment / Use Cases
The ST2000SPEXI adapter serves multiple roles in modern IT infrastructure, from basic network expansion to advanced virtualization deployments. Its dual-port design and enterprise features make it suitable for various server and workstation applications.
In virtualization hosts, the adapter can dedicate one port to management traffic and another to VM data traffic, or utilize both ports in teaming configurations for increased bandwidth and redundancy. For file servers and backup systems, the dual ports enable separate connections to different network segments or storage networks. The included low-profile bracket allows installation in space-constrained 1U and 2U server chassis commonly found in data center environments.
Server Network Expansion
Add dedicated network interfaces for management, backup, or application traffic without consuming motherboard ports.
Virtualization Infrastructure
Provide hardware-accelerated networking for hypervisors with SR-IOV support for direct VM access to network resources.
Physical Profile
The adapter features a compact plug-in card design measuring 4.80" (121.92 mm) in height, 0.70" (17.78 mm) in width, and 2.60" (66.04 mm) in depth, with an approximate weight of 2.80 oz (79.38 g). This form factor fits standard PCI Express slots in tower servers, rackmount systems, and workstations. The card ships with both standard and low-profile brackets to accommodate full-height and half-height chassis configurations.

User Manual
FAQ
What type of PCI Express slot does this adapter require?
The ST2000SPEXI uses a PCI Express x4 interface but is physically and electrically compatible with x4, x8, and x16 PCIe slots. It complies with PCI Express Base Specification 2.1 and maintains backward compatibility with 1.0a and 1.1 specifications, ensuring broad compatibility with server and workstation motherboards.
Does this network adapter support link aggregation or teaming?
Yes, the adapter fully supports IEEE 802.3ad link aggregation (also known as port trunking or teaming). This allows both ports to be combined into a single logical interface for increased bandwidth or configured for failover redundancy. The feature works with compatible operating systems and network switches that support link aggregation protocols.
What virtualization features does the Intel i350 chipset provide?
The Intel i350-AM2 chipset includes Intel Virtualization Technology for Connectivity (VT-c), which encompasses Virtual Machine Device Queues (VMDq) and Single Root I/O Virtualization (SR-IOV). VMDq improves virtual machine network performance through hardware-assisted packet sorting, while SR-IOV allows direct hardware access for virtual machines, reducing virtualization overhead and improving network throughput in virtualized environments.
Can this adapter be installed in low-profile or half-height server chassis?
Yes, the adapter includes both a standard full-height bracket and a low-profile/half-height bracket in the package. The low-profile bracket allows installation in space-constrained 1U and 2U server chassis, workstations, and small form factor systems that require half-height expansion cards.
What offload capabilities does this network adapter support?
The adapter supports multiple hardware offload engines to reduce CPU utilization: Checksum Offload for IP, TCP, and UDP protocols; Transmit Segmentation Offload (TSO) for TCP and UDP; and Large Send Offload (LSO). These features enable the network controller to handle packet processing tasks that would normally burden the server CPU, improving overall system performance during network-intensive operations.
What is included in the warranty coverage for this product?
StarTech.com provides a 2-year limited warranty for the ST2000SPEXI network adapter. The warranty covers defects in materials and workmanship under normal use. The product also carries EU RoHS environmental certification and complies with Restriction of Hazardous Substances (RoHS 2), REACH, and WEEE directives for environmental responsibility.
