Hello Guys,
Here at University of Palermo (Italy) we are planning to switch from
vmware to ovirt using the hyperconverged solution.
Our design is a 6 nodes cluster, each node with this configuration:

- 1x Dell PowerEdge R7425 server;
- 2x AMD EPYC 7301 Processor;
- 512GB of RAM (8x 64GB LRDIMM, 2666MT/s, Quad Rank);
- 2x Broadcom 57412 Dual Port 10Gb SFP+ ethernet card;
- 3x 600GB 10K RPM SAS for the OS (Raid1 + hotspare);
- 5x 1.2TB 10K RPM SAS for the hosted storage domain (Raid5 +
hotspare);
- 11x 2.4TB 10KRPM SAS for the vm data domain (Raid6 + hotspare);
- 4x 960GB SSD SAS for an additional SSD storage domain (Raid5 +
hotspare);

Is this configuration supported or I have to change something?
Thank you and Best Regards.

Hi,

Recently it was mentioned that there were some issues with the 'too new' EPYC.
For now, you can do :
1. Use some old machines for initial setup of the HostedEngine VM (disable all Spectre/Meltdown in advance) -> and then add the new EPYC-based hosts and remove the older systems. Sadly, the older  systems cannot be too old :)

2. Host the HostedEngine VM on your current VmWare environment or on a separate KVM host. Hosting the HostedEngine on bare metal is also OK

3. Wait (I don't know how long) till EPYC issues are solved.

Thank you.
Maybe it's better to use Intel processors?
Best Regards.
