Hi all,

Could you please tell me how many VM I can run on that hardware please ?

1 X AMD Opteron 4334 3.1 GHz+/ 3.5 GHz+ Burst (6 Core / 6 Thread)
32Go DDR3 ECC
2x 2 To SATA3 Disk Raid Soft
1 X 1Gbps Port
300 Mbps Bandwidth

Is it okay with 30 machines with 1vCPU or 15 with 2vCPU ....but maximum 30vCPU count ?

I think I ll use Microsoft HyperV and sell VPS.


Thanks you

There is so much more to this than just the hardware. What kind of virtual machines are you talking about? What operating system? What is your data storage going to be like when you are running 30 virtual machines simultaneously?

Even with a very VERY lightweight virtual machine, I don't think that hardware is really going to be capable of running 30 VMs. Half of that maybe. And even then you are going to need to look into better storage system (SAS drives at minimum) and network throughput (four gigabit network interfaces minimum) for even 15 decent VMs. Now, others may say that I'm underestimating the hardware capabilities but it all just depends on so many factors like your operating system and the intended usage for each VM on your server.

choucove,

I think most of VM will be Linux system but we plane to offer windows vps too.

I can change this 2 X 2 To Sata3 6 Gbps Raid Soft to this : Raid HARD+ LSI 9271-4i Cachevault 1 Go 2x 600Go SAS 15K + Cachecade 80Go SSD
It will be good with that hard drive infrastructure ?

About Network card I cannot change the 1 X 1 Gbps port for internal/external if I want to change that I need to take another server more expensive but with a 10 Gbps Network card.

Do you think it will be a handicap if I keep 1 X 1 Gbps and if I only change hard drive ?

Thanks you

Again, there's no possible way that we will be able to answer this for you because we do not know the end usage of your virtual machines. Will a single gigabt ethernet controller offer you enough throughput for all of your virtual machines simultaneously? Possibly, depends on the type of workload and how many a simultaneously having data transfer, but that's a huge bottleneck right there. So unfortunately I don't really have an answer for you there. Going with a hardware RAID controller with SAS drives is definitely going to improve the throughput performance capabilities of your storage. Again, I don't know what the end usage of your VMs or the expected performance per VM is going to need to be so perhaps it isn't necessary, but it definitely will make a difference with the higher performance drives.
