A.1. Pre-install preparation
Figure 2 shows an NSS HA cluster. The equipment list for NSS-HA includes:
 2 PowerEdge R710 servers
 1 PowerConnect 5424 Gigabit Ethernet switch
 2 Switched APC AP7921 power PDUs
 1 PowerVault MD3200
 1 or 3 PowerVault MD1200s
Gigabit Ethernet IP addresses for the private network between the servers and the PDUs.
All IPs should be on the same subnet. Noted here are the IP addresses that were used in the test
configuration.
 Active server NIC1 IP – 15.15.10.1/24
 Passive server NIC1 IP – 15.15.10.2/24
 Active server iDRAC IP – 15.15.10.201/24
 Passive server iDRAC IP – 15.15.10.202/24
 PDU 1 IP – 15.15.10.101/24
 PDU 2 IP – 15.15.10.105/24
Public network IP addresses for the network that is shared with the NFS clients.
These IPs should be on the same subnet as the clients. Noted here are the IP addresses that were used
in the test configuration.
 Active server 10GbE/IPoIB IP address – 10.10.10.201/16
 Passive server 10GbE/IPoIB IP address – 10.10.10.202/16
 Floating resource IP that the clients will use to mount NFS – 10.10.10.200
