The Cisco Nexus 2248TF Fabric Extender (FEX) is designed to extend the Cisco Nexus switch fabric to provide scalable, high-performance, and reliable network connectivity for servers and storage devices. To achieve optimal performance and reliability of the N2K-C2248TF FEX, several factors need to be considered:
- Network Design: The network design should be carefully planned to ensure that the FEX is correctly integrated with the Nexus switch fabric. This involves selecting the appropriate uplink modules and cables, configuring the FEX interfaces, and establishing redundancy and failover mechanisms.
- Uplink Bandwidth: The uplink bandwidth is critical to achieving optimal performance of the FEX. The Nexus switch should be equipped with sufficient uplink bandwidth to support the data traffic generated by the FEX. In addition, link aggregation should be used to increase the uplink bandwidth and provide redundancy.
- Quality of Service (QoS): QoS policies should be configured to ensure that critical data traffic is prioritized and delivered with low latency and high reliability. This is especially important in environments where real-time applications, such as voice and video, are used.
- Server Connectivity: The FEX provides connectivity to servers through the use of Unified Port (UP) technology. UPs allow the FEX to auto-detect the type of device connected to each port and configure the port accordingly. This simplifies server deployment and reduces the need for manual configuration.
- Management: The FEX can be managed through the Cisco Nexus switch or through an external management system. The management system should be configured to monitor the FEX and provide alerts when issues arise. This enables proactive management and reduces the risk of downtime.
The N2K-C2248TF is a Cisco Nexus 2248TF Fabric Extender, which is a device that allows you to extend the capabilities of a parent switch over a fabric. It provides a high-speed, low-latency, and scalable solution for connecting servers and other devices to the network.
From a security standpoint, the N2K-C2248TF provides several features and management options that help ensure the security of your network. For example, it supports Secure Shell (SSH) and Simple Network Management Protocol version 3 (SNMPv3), which provide secure remote access to the device and allow for secure management of the network. It also supports the Cisco TrustSec feature, which provides identity-based network access control and data confidentiality.
The N2K-C2248TF also supports various management options, including a web-based graphical user interface (GUI) and a command-line interface (CLI). The GUI provides an intuitive interface for configuring and monitoring the device, while the CLI allows for more advanced management options and automation.
Furthermore, the N2K-C2248TF supports various network protocols, including Virtual Extensible LAN (VXLAN) and Locator/ID Separation Protocol (LISP), which provide efficient and scalable network virtualization and overlay solutions.
Power Consumption and Energy EfficiencyThe Cisco Nexus 2248TF Fabric Extender (FEX) is a device that extends the Cisco Nexus switch fabric to access ports in a data center network. It provides 48 100/1000BASE-T host facing ports and four 10 Gigabit Ethernet uplink ports to the parent Cisco Nexus switch. The power consumption and energy efficiency of the N2K-C2248TF FEX depend on several factors, including the operational state, configuration, and environmental conditions.
Power Consumption: The N2K-C2248TF FEX has a maximum power consumption of 256 watts. This power consumption is for the fully loaded FEX with all 48 host-facing ports and four uplink ports active. However, the actual power consumption may vary depending on the number of ports that are in use, the type of traffic, and the environmental conditions.
Energy Efficiency: The energy efficiency of the N2K-C2248TF FEX can be determined by calculating its power efficiency rating (PER). The PER is the ratio of the device's power consumption to the amount of data transmitted through it. A higher PER indicates greater energy efficiency.
The N2K-C2248TF FEX has a PER of 29.6 Gbps/watt, which is relatively high and indicates excellent energy efficiency. This efficiency is achieved through the FEX's use of low-power, high-speed, and highly integrated components.
In addition to the PER, the N2K-C2248TF FEX also supports energy-saving features such as the Cisco Energy Efficient Ethernet (EEE) standard. EEE reduces power consumption during periods of low network activity by automatically adjusting the power levels of the Ethernet interface.
