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 5. 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
