5 Benefits You Get When Buying a Top of Rack Switch Nexus 3100V:

  1. 100G uplinks: Cisco predicts that global data center IP traffic will grow 31% every year in the next 5 years. For this, it is obvious that 100G is the new norm for higher bandwidth, big data, and IP storage workloads.
  2. 16 MB enhanced buffers: Compared to 12MB buffer from previous generation, the Nexus 3100V models offer 16 MB enhanced buffers to absorb bursts of traffic and applications. You won’t have to worry when you need to expand your network in the future, because these deep buffers are designed for highly oversubscribed environments.
  3. 16 GB Increased system memory: In the previous model – Cisco Nexus 3100XL – Cisco already increased the system memory from 4GB to 8GB in order to introduce network programmability features developed in NXOS 7.x. But as networks are becoming more complex, competitive businesses need more memory to store more objects. Hence, Cisco has doubled the capacity again in the Nexus 3100V models from 8GB to 16GB to improve capacity for object-model programming.
  1. Quadrupled ingress ACL table size to 16,000: for more greater securitytraffic control, enhanced security, and policy management flexibility
  1. Support full VxLAN routing (layer 3 VxLAN): With this, workloads in different segment IDs can directly communicate, whereas with VxLAN bridging (layer 2 VxLAN), workloads need to be in the same segment ID to interact.

Cisco continues to bring you true flexibility and scalability through rich architectural options for any size of data center to address increasing business requirements. You can never go wrong with more connectivity options and a diverse set of form factors to meet ever-changing data center needs.
