Hi
I installed vertica-9.2.1 on 3 node3
and then I have noticed a HINT

`Detected significant differences in the cluster:
HINT: Differences in RAM (kbytes):
verify-192.168.0.233.xml: 8008964
verify-192.168.0.232.xml: 8008972
verify-192.168.0.231.xml: 8008964
For more information, see
https://www.vertica.com/docs/9.2.x/HTML/index.htm#cshid=CLREQ01

System prerequisites passed. Threshold = FAIL
`

Will this have a serious influence on the cluster？

    In your case the influence is not dramatic but as mentioned it is advised to have the same RAM on all nodes.
