The amount of virtual CPUs, memory, and disk space that Veritas Resiliency Platform requires are listed in this section.
The minimum configuration that is recommended for a virtual appliance for Resiliency Manager, Infrastructure Management Server (IMS), Replication Gateway, and YUM repository server:
Table: Minimum configurations
|
Component |
Minimum configuration |
|
Resiliency Manager |
Disk space 60 GB RAM 32 GB Virtual CPU 8 |
|
Infrastructure Management Server (IMS) |
Disk space 60 GB RAM 16 GB Virtual CPU 8 |
|
Replication Gateway |
Disk space 40 GB RAM 16 GB Virtual CPU 8 Additional external disk of 50 GB |
|
YUM repository server |
Disk space 60 GB RAM 4 GB Virtual CPU 2 |
|
Hosts to be added to Veritas Resiliency Platform:
|
Disk space 15 GB RAM 4 GB Dual processor CPU If you are using a single host for multiple purposes, add the disk space and RAM required for each purpose. For example, if you are using a single host as Windows Install host and as application host, then you need to have at least 30 GB disk space and 8 GB RAM. Note that you cannot use a single host as a Windows Install host as well as Resiliency Platform Data Mover host. |
|
You need to reserve the resources for Resiliency Manager and IMS to ensure that these resources do not get swapped in case of hypervisors getting overloaded. |
If the virtual appliance does not meet the minimum configuration, you get a warning during the bootstrap of the virtual appliance and you are required to confirm if you want to continue with the current configuration.
If you plan not to use the YUM virtual appliance, you need a Linux server with a minimum of 50-GB disk space, to be configured as the repository server. Provisioning for the repository server is optional, it is required to install the Veritas Resiliency Platform patches or updates in the future.

If you want to enable dynamic memory on Hyper-V, make sure that the following prerequisites are met:
-
Startup memory and minimal memory should be equal to or greater than the amount of memory that the distribution vendor recommends.
-
If you are using dynamic memory on a Windows Server 2012 operating system, specify Startup memory, Minimum memory, and Maximum memory parameters in multiples of 128 megabytes (MB). Failure to do so can lead to dynamic memory failures, and you may not see any memory increase in a guest operating system.
Even if you are using dynamic memory, the above mentioned minimum configuration should be met.
