Well good, we can at least bounce ideas off each other, and I'm sure we'll get some good advice sooner or later! Best way to get good ideas on the internet is to post bad ones and wait ;) In the performance and sizing guide PDF, they make this statement: *Standard servers with 4:2 erasure coding

Vincent, I've been back and forth on SSDs vs HDDs and can't really get a clear answer. You are correct though, it would only equal 4TB usable in the end which is pretty crazy but that amount of 7200 RPM HDDs equals about the same cost as 3 2TB ssds would. I actually posted a question to this

I always found replica 3 a complete overkill. Don't know people made that up that was necessary. Just looks good and costs a lot with little benefit. Normally when using magnetic disks 2 copies are fine for most scenarios, but if using SSDs for similar scenarios depending on the configuration of

Jayme, I'm doing a very similar build, the only difference really is I am using SSDs instead of HDDs. I have similar questions as you regarding expected performance. Have you considered JBOD + NFS? Putting a Gluster Replica 3 on top of RAID 10 arrays sounds very safe, but my gosh the capacity

Thanks for your feedback. Any other opinions on this proposed setup? I'm very torn over using GlusterFS and what the expected performance may be, there seems to be little information out there. Would love to hear any feedback specifically from ovirt users on hyperconverged configurations. On

Hello, we're planning an upgrade of an old 4.0 setup to 4.2, going through 4.1. What we found out is that when upgrading from major to major, cluster and datacenter compatibility upgrade has to be done at the end of the upgrade. This means that we also require to restart our VMs for adapting the

The norm is to have a cluster with shared storage. So you have 3 to 5 hardware noed that shares storage for the hosted engine. That shared storage is in sync. So you don't have one engine per physical node. If one hardware node goes down the engine is restarted on another node with the help
