Deployment Guide

15 VxFlex Network Deployment Guide using Dell EMC Networking 25GbE switches and OS9
Table 1 and Table 2 show how to calculate the IP address requirements. To accommodate expansion each
address pool is assigned a dedicated subnet.

IP address pools
The pools of IP addresses used for the following groups:
ESXI_MGMT_IP = Management IP addresses
ESXI_VMOTION_IP = ESXi vMotion IP addresses
SVM_MGMT_IP = SVM management IP addresses
IDRAC_MGMT_IP = iDRAC IP address for each node
The formula to calculate IP address subnet pool or subnet needs is: N * ESXI_MGMT_IP + N *
ESXI_VMOTION_IP + N * SVM_MGMT_IP + N * IDRAC_MGMT_IP

Data network 1
The pools of IP addresses used for static allocation for the
following groups:
1. Node_DATA1_IP = VxFlex internal (interconnect) IP
addresses
2. SVM_DATA1_IP = SVM management IP addresses
3. MDM_Cluster_Virtual_IP_DATA1 = The virtual IP of
the MDM cluster in the Data1 network
For clarity, the first subnet
is referred to as “Data1”.
The formula to calculate the subnet pool or subnet needs is:
N * Node_DATA1_IP + N * SVM_DATA1_IP + MDM_Cluster_Virtual_IP_DATA1
Data network 2
The pools of IP addresses used for static allocation for the
following groups:
1. Node_DATA2_IP = VxFlex Nodes internal
(interconnect) IP addresses
2. SVM_DATA2_IP = SVM management IP addresses
MDM_Cluster_Virtual_IP_DATA2 = The virtual IP of the
MDM cluster in the Data2 network
For clarity, the first subnet
is referred to as “Data2”.
The formula to calculate the subnet pool or subnet needs is:
N * Node_DATA2_IP + N * SVM_DATA2_IP + MDM_Cluster_Virtual_IP_DATA2
