SAS HDD SAS 2.5" Seagate Savvio 10K.6 900GB 6Gb/s 10000RPM 64MB x 4
Raid 6 assembled.
Actually, the task is to raise MS Windows Server 2012 (AD, MS SQL, DNS, 1C Server), Linux Server (ownCloud, Samba, Ftp, Redmine, GitLab) and Linux Server under Backup and FileStorage.
Now raised on one old Proxmax server, it has 5 KVM machines.
I didn’t try anything from hypervisors, I read the main pros and cons by searching, in principle, I understand, I’ll honestly test everything anyway, but I would like to hear your opinion on what you would raise on such pieces of iron.
And of course I want to know the opinion of anyone who is worth or stood and what are the feelings from using it.
There is another question regarding Hyper-V, whether Ubuntu gets up on them or not.

Answer 1

There are two main players on the market today. ESXi and Hyper-V. Everything works super and everything requires direct hands. Well, then ... The taste and color ....! =)

Answer 2

I have experience with unstable Linux, namely RedHat on Hyper-V, so I do not recommend it.
I used ESXi and vSphere 5.1 in production with a zoo of VMs, almost everything suited me (the variant of the influence of the curvature of the hands is not excluded).
I played with Proxmox, it seems not bad, I heard they are deploying production on it. the same Xen.
But! to organize the work of a full-fledged cluster, you need a shared storage.
therefore:
1. if there is a very limited budget for licensed software, you need to look towards XCP and Proxmox.
2. if there is no restriction in paragraph 1, choose what you like best, according to the way your question is formulated, no specific tasks are set for the virtualization platform.

Answer 3

I'll be honest, I'll test anyway

Taking this opportunity, I will ask you to record the results of the comparison and place it in a place accessible for reading.

Answer 4

I use XenServer from Citrix. Almost the same as yours has been raised, it has been working for more than a year, there are no complaints. And so, it is difficult to advise, here the question of money is more.

Answer 5

I ran a diverse zoo under VMware - everything worked fine, + it was convenient to administer everything, configure HA, and so on.

Answer 6

what matters here is what you know.
since if there are problems with the hypervisor, then you need to understand the OS of the hypervisor.
if with Linux on a short leg, then ESX is perfect.
and iESX seems to be free
with a motley company, it works well.
and if you don’t really know Linux, then Hyper-V is better
there is a regular Windows. but for the money, if not the Hyper-V version
