Pro Disk Network Buyer’s Guide: Network Switches

Optic Coding, Vendor Lock-In, and Multi-Vendor Compatibility

If you are running a multi-vendor leaf-spine architecture (Arista leaves and Cisco spines, for example), order optics coded for each endpoint separately. Optics in DAC and AOC cables are factory-coded to each end and cannot be flashed in-field. Plan the coding split at design time and document it in your network drawings.

Bandwidth Sizing for Spine-Leaf, EVPN-VXLAN, and Hyperconverged Storage

Sizing network bandwidth for a leaf-spine fabric using the WS-X4418-GB starts with the workload mix. For general-purpose virtualisation, plan 10G server-to-leaf, 25G or 40G leaf-to-spine; oversubscription up to 4:1 is acceptable. For hyperconverged storage (vSAN, Ceph, Storage Spaces Direct), plan 25G server-to-leaf at minimum, 100G leaf-to-spine, oversubscription 1.5:1 maximum. East-west traffic dominates in HCI clusters and starves on oversubscribed fabrics.
