The JNK9N Dell Broadcom 57840S Quad-Port 10GB Blade Daughter Card NIC is a high-performance network interface card designed for use in servers and workstations. It is an excellent choice for users who require reliable and high-speed network connectivity. In this article, we will discuss the key features and benefits of the JNK9N Dell Broadcom 57840S Quad-Port 10GB Blade Daughter Card NIC.
The JNK9N Dell Broadcom 57840S Quad-Port 10GB Blade Daughter Card NIC is a PCIe 3.0 adapter that comes with four 10 Gigabit Ethernet ports. The adapter is compatible with a range of operating systems, including Microsoft Windows, Linux, and VMware ESXi. The adapter supports IEEE 802.1Q VLANs and IEEE 802.3ad Link Aggregation Control Protocol (LACP), allowing users to increase network bandwidth and improve network reliability.
The adapter uses Broadcom's NetXtreme II technology to improve performance in virtualized environments. NetXtreme II technology enables the adapter to allocate multiple queues per virtual machine, allowing for improved network performance in virtualized environments. Additionally, the adapter supports TCP/IP offloading, which offloads data processing tasks from the CPU to the network adapter, further improving network performance.
The adapter also features Broadcom's Advanced Control Suite (BACS), which includes features such as teaming, load balancing, and fault tolerance. These features enable users to group multiple adapters together to increase network bandwidth and improve network reliability. The adapter also supports jumbo frames, which allows for the transmission of larger data packets, further improving network performance.
The JNK9N Dell Broadcom 57840S Quad-Port 10GB Blade Daughter Card NIC offers several key benefits, including:
High-speed network connectivity: With four 10 Gigabit Ethernet ports, the adapter provides high-speed network connectivity for servers and workstations.

About Refurbished Products
Adding gigabyte network connectivity is one of the best decisions users can make in the modern world. This is what the NIC (Network Interface Card) offers. This highly advanced networking device offers users a dedicated computer network connection.
The network interface card's ability to support wired and wireless network communications makes it one of the best choices. Individual users and IT professionals will find them very useful.
NIC enables adequate communication between computers. The computers may either be connected over a Local Area Network or over larger-scale networks via an IP. Regardless of the connection type, the network interface card offered at AllHDD works at optimal rates.
When users choose network interface card options here, they get the most reliable hardware circuitry. That is, there's a synergy between a data link and a physical layer in one device. The circuitry enables the physical layer to process data so that the processes involving the data link layer can run effectively on it.
Gone are the days when network controllers were the real deals. Today, a network interface card can serve as an expansion module in computer systems or routers. The specifications of the NIC users will get correspond with the standard of various network options.
Network Interface Card Options
Internal Network Interface Cards
Users will find NIC (Network Interface Cards) that users can insert directly onto the computer's motherboard. For these options to offer network access, there's the need for network cables. There are NIC options that use connections like Peripheral Component Interconnect (PCI). Others connect with Industry Standard Architecture (ISA).
External Network Interface Cards
Laptops and desktops which do not come with an internal network interface card use the external option. There are two options for the external NIC. The first is the wireless network cards, which will be attached directly to the motherboard.
Unlike the internal option, there will be no need for networking cables in this case. These options are the best when users need to travel or access wireless signals.
On the other hand, there are several USB options ranging from 1 port to 4 port NIC. They are compact, and they add a network connection to a USB-enabled computer system. Many of these NIC options work with 10-100-1000 Mbps networks.
They are also ideal replacements for local area network (LAN) adapters and similar laptop accessories. Users will find USB network interface cards that support features such as VLAN tagging, Jumbo Frames, and Wake on LAN (WOL). They are the most reliable Gigabit network for versatile home and business use.
- Fast and Reliable Performance. The network interface cards have impressive speed ratings with options up to 1000 Mbps. They enable the connection of multiple computers without the fear of failure.
- Updated and Incorruptible Driver. The driver that passes data between the NIC and the computer system ensures optimal performance.
- Connectivity LED. These NIC (Network Interface Cards) come with integrated LED indicators to notify users when there is a network connection and transfer of data.
