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.
Best Regards,
