Description Vagner Farias 2014-02-18 13:36:12 UTC

Title: Red Hat Enterprise Virtualization Manager Hardware Requirements

Describe the issue:
Minimum RAM is said to be 4GB, but if Data Warehouse is installed, this is not enough even for small deployments - 2 hosts, 2 dozen VMs.


Suggestions for improvement:
Either state that 4GB is minimum if Data warehouse is not installed or increase the minimum requirement.

Comment 1 David Ryan 2014-10-03 12:08:44 UTC

Vagner - do you not feel that the following sentence defines the absolute minimal supported quantity RAM? And that the Recommended values are sufficient?

"Minimum - 4 GB of available system RAM that is not being consumed by existing processes"

"Recommended - 16 GB of system RAM.

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Virtualization/3.4/html-single/Installation_Guide/index.html#Red_Hat_Enterprise_Virtualization_Manager_Hardware_Requirements

I feel that this is a reasonable depiction with sufficient precedent. This covers our bare minimum value per our technical support, while also stating a value that we recommend our customers use. Our user persona reasonably expects them to follow this recommended advice.

What do you think?

Comment 2 Vagner Farias 2014-10-06 20:07:42 UTC

David, my suggestion would be something like:

"Minimum - 4 GB of system RAM if Data Warehouse is not installed or if memory is not being consumed by existing processes"

"Recommended - 16 GB of system RAM."

My point is that Data Warehouse is part of RHEV and my experience shows that 4 GB is not enough, so I believe it's important to state that more RAM is required in this situation.

Reviewed for docs QE.

The 'minimum requirements' section of the topic has been updated to address the concerns raised by this bug. Specifically, the minimum value is given with the caveat that Data Warehouse is not installed, and that the memory is not being consumed by existing processes.

VERIFIED.
