Switch requirements

The SOFS solution requires a minimum of two physically separate switches to provide resilient connectivity between the storage nodes and clients. Divide each of the two switches to accommodate at least four subnets for external and internal cluster communication. You may require additional switches for cluster management. These requirements do not apply to the Converged solution.

Table 1. Switch ports required for each subnet . Switch ports required for each subnet
Subnets Number of ports for each server Description
Subnet 1 — Management

2 ports (Management) 1 port (iDRAC)

Typically routed through separate switches. Use existing network if necessary.
Subnet 2 — External communication to SMB clients 1 port on Switch 1 Subnet 2 and Subnet 3 are resilient paths through separate switches.
Subnet 3 — External communication to SMB clients 1 port on Switch 2
Subnet 4 — Internal communication between cluster nodes 1 port on Switch 1 Subnet 4 and Subnet 5 are resilient paths through separate switches.
Subnet 5 — Internal communication between cluster nodes 1 port on Switch 2
