The StarTech.com 1-Port 40G QSFP+ Network Card delivers the ultimate upgrade for data centers, enterprise servers, and high-demand workstations that require ultra-fast fiber connectivity. Built around the Intel XL710 chipset, this Open QSFP+ converged adapter provides a single 40 Gigabit Ethernet port via a PCIe interface, enabling accelerated workloads, improved virtualization performance, and scalable network fabric integration. Designed for modern servers, it supports 40GBASE-SR4 fiber optics and compatible DAC cables, ensuring versatile, high-bandwidth links for critical applications like HPC, virtualization clusters, storage networks, and database acceleration. Expect lower latency, higher throughput, and efficient CPU offloads that keep your applications running at peak performance.

  • Blazing-fast 40GbE connectivity: Harness the power of a single QSFP+ port delivering 40 Gb/s bandwidth to handle demanding workloads with ease. Ideal for data-intensive tasks such as large-scale virtualization, real-time analytics, and high-performance computing. The Intel XL710 controller provides robust, reliable throughput with low-latency packet processing to accelerate your most mission-critical applications.
  • Open QSFP+ converged adapter design: Open QSFP+ supports flexible fiber connectivity options, including 40GBASE-SR4 optics and DAC cables, enabling seamless integration into diverse network fabrics. This converged approach simplifies cabling, reduces switch port pressure, and helps you scale your data center without switching to multiple adapters.
  • PCIe 3.0 host interface for broad compatibility: Designed to plug into PCIe 3.0 x8 slots in servers and workstations, delivering dependable, high-bandwidth access to system memory and CPU for optimized packet handling. This ensures compatibility with a wide range of server platforms while maintaining strong performance headroom for multicore processing.
  • Advanced offloads for virtualization and efficiency: Intel XL710 offloads tasks such as VLAN tagging, large send/receive offloads, RSS for balanced multi-core processing, and virtualization features like SR-IOV and NIC teaming. These capabilities reduce host CPU utilization and improve VM density, enabling you to run more virtual machines per host with predictable networking performance.

Perfect cup.
Flavor Name: Variety Pack 2, Size: 16.5 fl oz (Pack of 4)
I was really happy with the value of money I pay for this set because I’m able to make the perfect cup of coffee at home and save on going to Starbucks or Dutch Bros. They taste so yummy. It’s easy to use.

Café-Quality Sauces at Home ☕🍫
Flavor Name: Variety Pack 2, Size: 16.5 fl oz (Pack of 4), Flavor Name: Variety Pack 2, Size: 16.5 fl oz (Pack of 4)
Absolutely love this Torani Puremade variety pack. Every sauce tastes rich, smooth, and high quality just like what you’d get at a coffee shop. The caramel is perfectly buttery, the white chocolate is creamy (not overly sweet), and both chocolate sauces are deep and indulgent. They blend beautifully into hot and iced drinks, drizzle great over desserts, and the squeeze bottles make them super easy to use with no mess. I also really appreciate that they’re made with no artificial flavors or preservatives. If you’re building a home coffee bar or love elevating desserts, this set is 100% worth it. Would definitely repurchase.

Gourmet drizzle of deliciousness
Flavor Name: Variety Pack 2, Size: 16.5 fl oz (Pack of 4)
Torani is a great product - very happy we were able to order them through Amazon. They last without being refrigerated (but we go through them fast during parties). The syrups taste like they're from an ice cream shop - we use them for ice cream parties for variety. This set is a great price compared to buying in-store. The syrup is not watery, it's a nice thick syrup that is great for coffee or desserts. The consistency is not as thick as a fudge topping, but thick enough to drizzle, if that makes sense. Will buy again!
