The control plane might consist of one or two servers depending on whether your configuration includes a stand-alone image server or has the image server residing on the control plane server.
The control plane server contains the N1 Provisioning Server software , which fulfills the following roles:
N1 Provisioning Server database (CPDB)
Storage manager client (STMC)
Farm manager
Segment manager
DHCP and DNS services
Monitoring manager
Control Center
Regularly back up the N1 Provisioning Server components, especially the CPDB.
The strategy for backing up a control plane server is to designate a server that is not part of the I-Fabric as a backup server and connect it to the control plane network. A variety of commercial backup software is available for performing backup. The only requirement is that it must be able to back up to Oracle or Postgres databases. When you install your N1 Provisioning Server, an IP address and port are designated for the backup server. See the N1 Provisioning Server 3.1, Blades Edition, Installation Guide for details.
The following section details the requirements for backing up and restoring a control plane server.
To configure a backup server perform the following steps:
Select a port on the control plane switch to connect a backup server.
Assign that port into virtual local area network (VLAN) 9.
Connect an appropriate tape backup device directly to the backup server.
The IP address x.y.z.212 has been reserved for the backup server. N1 Provisioning Server software provides the x, y, and z values. The x.y.z value is the subnet your N1 Provisioning Server uses. Configure the backup server to use this address.
Install and configure backup server software on the backup server according to the supplier's instructions and your local requirements.
The backup server must not route or bridge any Ethernet traffic between VLAN 9 and any other network to prevent unauthorized access to the N1 Provisioning Server network.
