Planning for high availability, Time clocks and NTP | HP OneView

•A connection to the management LAN. HP recommends that you have separate networks for management and data.

•The clock on the VM host must be set to the correct time. If NTP (Network Time Protocol) is not used to synchronize the time on the VM host, HP recommends configuring the appliance to use NTP directly.

7.5.2Planning for high availability

To use HP OneView in an HA (high availability) configuration, verify that the VM is configured according to vSphere Hypervisor HA requirements. For more information, see your vSphere Hypervisor documentation or the following website:

http://www.vmware.com/products/datacenter-virtualization/vsphere/high-availability.html

7.5.3 Location of the appliance

HP recommends that you do not run the virtual appliance on a host that is to be managed by the same appliance instance.

7.5.4 Separate networks for data and management

HP recommends having separate networks for management and data.

7.5.5 Time clocks and NTP

HP recommends using NTP on the host on which you install the virtual appliance. If you are not using NTP on the host, HP recommends configuring NTP directly on the virtual appliance. Do not configure NTP on both the host and the virtual appliance.

7.5.6 IP addresses

You must specify what type of IP addresses are in use and how they are assigned to the appliance, either manually by you or assigned by a DHCP (Dynamic Host Configuration Protocol) server:

•You must choose either IPv4 or IPv6 addresses.

•The appliance IP address must be static.

•If you use a DHCP address for the appliance it must have an infinite lifetime or permanent reservation.
