Home virtualization?

Question

Iron

Tell me the characteristics of the hardware for a powerful virtualization server if you choose from desktop hardware

Answer 1

I can only say that if you buy a processor from Intel, then make sure that there is no letter "K" in the marking. Models with "K" are overclockable, but they do not have hardware support for virtualization.

Answer 2

Something I do not understand why everyone advises strictly Intel
If there is a desire to save money, then I would recommend AMD.
AMD processors are of course weaker, but they are also cheaper, an 8-core 8320 is cheaper than a 4-core i5, motherboards with ECC support for Intel are almost twice as expensive.
The only thing that may cause problems with RAID, I have a
GA-890FXA-UD5
AMD Phenom II X6 1090T at work.
Admins before me tried to install some kind of hypervisor, but something didn’t work out for them, I got a custom ESXI 5.5, now it’s spinning 5 virtuals.
The only problem is that the Intel raid did not start, it is not compatible with this hardware.

Answer 3

More RAM (from 32GB) and processor cores (from 8). A good SATA controller with at least 6 ports is also desirable.
Everything depends on the hypervisor. I use Xen for example.
The virtual network between the host (opensuse) and the guest (win server 2008) delivers 7 gigabits per second. Naturally, after installing special drivers.

Answer 4

First you need to decide on the questions below:
What will the Hypervisor be like?
How many virtual machines will there be?
How many resources are needed for virtual machines?
And based on the answers, already think about the hardware.

Answer 5

I have one like this at homestands, KVM hypervisor + containers on OVZ, as a PERC H810 RAID controller with a gig of non-volatility memory and two SSD 512 as a cache cad, two E5-2600 v2 processors and 64 gigabytes of memory, about 40 virtual machines and the same number of containers are spinning on this, systems are different and free and win and a pack of Linux and various rare ones, everything pulls, it doesn’t blunt anywhere - I’m satisfied. I don’t really advise you to assemble from desktops, if you put normal raid controllers, disks and memory on them, then the price will not differ much from a ready-made server solution, and ease of maintenance is several times lower, besides, if necessary, desktops scale very badly if -the same dell that I have, I initially took it with 1 processor, 2 disks, without an SSD and with 8 gigs of memory, and then I just grew it as needed, then a desktop upgrade is to throw it away entirely and buy a new one.

Answer 6

I would dance from the hypervisor. If we take, for example, ESXI, it is quite picky about hardware. Those. or collect based on the whitelist, or play roulette.
Again, for virtualization, one of the main elements is the amount of memory, and on home hardware this will be a problem.
I also thought and wondered, and then spat and took the mother of the supermicro and xeon e5, so as not to run into memory.
