<div class="moz-cite-prefix">Hi,<br>
<br>
HL ProLiant DL380, dual Xeon<br>
120 GB RAID L1 for system<br>
2 TB RAID L10 for VM disks<br>
5 VMs, 3 Linux, 2 Windows<br>
Total CPU load most of the time is low, high level of activity
related to disk.<br>
Host engine under KVM appliance on SuSE, can be easily moved,
backed up, copied, experimented with, etc.<br>
<br>
You'll have to use servers with more RAM and storage than main.<br>
More then one NIC required if some of your VMs are on different
subnets, e.g. 1 in internal zone and 2nd on DMZ.<br>
For your setup 10 GB NICs + L3 Switch for ovirtmgmt.<br>
<br>
BTW, I would suggest to have several separate hardware RAIDs
unless you have SSD, otherwise limit of the disk system I/O will
be a bottleneck. Consider SSD L1 RAID for heavy-loaded databases.<br>
<br>
<font color="#990000"><b>Please note many cheap SSDs do NOT work
reliably with SAS controllers even in SATA mode</b>.</font><br>
<br>
For example, I supposed to use 2 x WD Green SSD configures as RAID
L1 for OS. <br>
It was possible to install system, yet under heavy load simulated
with iozone disk system freeze, rendering OS unbootable.<br>
Same crash was experienced with 512GB KingFast SSD connected to
broadcom/AMCC SAS RAID Card.<br>

<pre wrap="">Hi all,
Not sure if this is the place to be asking this but I was wondering which hardware you all are using and why in order for me to see what I would be needing.
I would like to set up a HA cluster consisting off 3 hosts to be able to run 30 vm’s.
The engine, I can run on an other server. The hosts can be fitted with the storage and share the space through glusterfs. I would think I will be needing at least 3 nic’s but would be able to install ovn. (Are 1gb nic’s sufficient ?)
Any input you guys would like to share would be greatly appriciated.
Thanks,
