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'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
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
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
6 CentOS 7.4 Compute Nodes Intel Xeon
1 CentOS 7.4 Dedicated Engine Node Intel Xeon
1 Storage Domain
10Gig-E iSCSI Storage
10Gig-E NFS Export Domain
20 VM’s of various OS’s and uses
The current cluster is using the Nehalem architecture.

Amongst others, I have one 3.6 DC working very well since years and all

I never noticed or bothered before, but I'm wondering :
- is it by design?
- it is something
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
shot inthe dark, but have you got EPEL repo enabled by any chance?

Since it's still not installed, yes ;)

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.
