Cisco Nexus 2348UPQ
48 100Mῖ/1/10 Gigabit Ethernet and Unified Port host interfaces (SFP+) and up to 6ῖ QSFP+ 10/40 Gigabit Ethernet fabric interfaces.
The Cisco Nexus 2348UPQ Fabric Extender (Figure 2) is a general-purpose unified portῖ -capable 100 Megabitῖ. 1/10 Gigabit Ethernet fabric extender for workloads such as large-volume databases, distributed storage, and video editing. The Cisco Nexus 2348UPQ supports 48 1/10G host unified ports as well up to 6*40Gb uplink ports towards the parent switch. The 40G uplinks support BiDi Optics for simple connectivity using your existing cable plan. The unified ports provide connectivity to 2-/4-/8-/16-Gbps fiber channelῖ (24 ports for 16G) as well as 1/10 Gigabit Ethernet and FCoE connectivity options. The Nexus 2348UPQ has a deep 32-MB shared buffer that helps increase performance, and it supports FCoE and Data Center Bridging (DCB) network technologies that boost the reliability, efficiency, and scalability of Ethernet networks. These features allow support for multiple traffic classes over a lossless Ethernet fabric, enabling consolidation of LAN, storage area network (SAN), and cluster environments.
