Arista DCS-7280TR-48C6-R 48x RJ-45 10Gb 6x QSFP28 100Gb - Ethernet Switch

The Arista 7280R Series of #xed systems, including the 7280R, 7280RA, 7280R2, 7280R2A and the 7280R2K, are key components of the Arista 7000 Series portfolio of data center switches. The Arista 7280R Series are purpose built 10/25/40/100GbE systems built for the highest performance environments, and to meet the needs of the largest scale data centers and service providers They deliver scalable L2 and L3 resources and high density with advanced features for network monitoring, precision timing and network virtualization to deliver scalable and deterministic network performance while simplifying designs and reducing Opex. The 7280R capabilities address the requirements for modern networking and rich multi-media content delivery requiring a lossless forwarding solution in a compact and energy efficient form factor. The 7280R can be deployed in a wide range of open networking solutions including large scale layer 2 and layer 3 cloud designs, overlay networks, virtualized or traditional enterprise data center networks. Deep packet bu!ers and large routing tables allow for internet peering, interconnect and Inter-DC networking. The broad range of interfaces and density choice provides deployment flexibility. The 7280R Series are available in a range of models with a choice of 10GBASE-T, 10GbE and 25GbE SFP with 40GbE and 100GbE QSFP uplinks and systems that o!er up to 60 ports of wire speed 100GbE in a 2RU system. 7280R support for 100GbE QSFP incorporates a $exible choice of interface speed including 25GbE and 50GbE providing unparalleled flexibility and the ability to seamlessly transition data centers to the next generation of Ethernet performance. The 7280R Series provide industry leading power effciency with airflow choices for back to front, or front to back. An optional built-in SSD supports advanced logging, data captures and other services directly on the switch. Combined with Arista EOS the 7280R Series delivers advanced features for big data, cloud, virtualized and traditional designs. This device is perfect for:

• Data Center Top-of-Rack (ToR) This is a prime use case for the DCS-7280TR-48C6-R. With 48 x 10GBASE-T ports, it's an excellent choice for connecting a high density of servers in a rack. The six 100GbE QSFP28 uplink ports provide high-speed connectivity to spine or core switches, creating a high-performance leaf-spine network fabric. The deep packet buffer is particularly valuable here for handling the microbursts of traffic common in data center environments.
• High-Density Aggregation The combination of numerous 10GbE ports and high-speed 100GbE uplinks makes it ideal for acting as an aggregation switch. It can consolidate traffic from multiple access-layer switches and forward it to a core network or a central data center fabric.
• Cloud and Service Provider Networks Its robust feature set, including deep buffers, large routing tables, and support for features like MPLS and VXLAN, makes it a strong contender for cloud and service provider networks. It can be used for internet peering, data center interconnect (DCI), and building scalable, multi-tenant cloud architectures.
• IP Storage and Big Data Environments The deep packet buffer is a critical feature for these use cases. It helps to prevent packet loss in environments with large, bursty traffic patterns, such as those found in IP storage networks (like iSCSI) and big data workloads (e.g., Hadoop clusters). The low latency and high throughput are also essential for these performance-sensitive applications.
