Question about CPUs and Virtualization

I'm currently designing a new server architecture in colab with a server tech, we'll need 4 dedicated servers and he has recommended to setup server virtualization via Virtuozzo, his reasoning is that it will make it easy to migrate to better hardware when needed. This seems like a good idea but some devs are telling my that it will degrade the performance of the boxes is this true? His plan is to install OS on 2 x SATA(Raid 1) drives and then place the virtualization on 2 x SSD's (Raid 1)
I would like a 2nd opinion on this,
Does the virtualization degrade performance, IF it does then by how much? Is it really this convenient to use such a virtualization setup in reference to migration? Any other thing to consider?

Thanks!

Hello,

I know that servers with EPYC CPUs are very reliable, but are Ryzen servers reliable enough? I've seen there're many Ryzen servers on sale on Hetzner. If I rent a Ryzen server, do I need to reboot it every some days? Thanks a lot.

I am planning to upgrade my current, very old server (Dual E5-2430 Xeons, 12 cores/24 HT with SATA SSDs) which has been doing duty as a shared hosting server for around 400 websites. Have noticed slow website loading times. 95% sites are using PHP/MySQL(Wordpress).

From the time I got the server and now, so many new CPUs have come out and looks like the xeon e3/e5 lines have been discontinued. Dual scalable silver/gold xeon servers are out of my budget, so the only alternative is a E-2288G or a W-1290P (more interested in this one) xeon with NVMe drives. Passmark scores for these servers are much higher than my current one, but moving to these new servers will mean a downgrade in the number of cores.

Looking for some personal experiences with these E-2288G/W-1290P CPUs, so that I am not actually getting a downgrade by changing servers.

I don't need more than 64GB of RAM and a 2x2TB NVMe SSD is fine.

Hello,
Do you know this Intel Xeon Gold processor?
We recently received a request for quote a dedicated cloud server with this CPU
but it seems that they are not available in Amazon EC2, so I was wondering if they are available elsewhere

I'm seriously considering making a VPS service for sneaker bots. What's the most important thing to look out for when choosing a dedicated server for such a service? Are CPU cores the most important thing for efficiency or is it the RAM or what exactly? Thanks

Hello, if there is a 10 server just a 1U server with two 2 E5 CPUs, can i combine all of this 10 server and build one server so that i can install and use the system on 10 servers together? Is it possibe?

Hello, my name is David, new member

I'm recently learning about using server hosting or providing services.
And I realized that server hosting should also be provided to meet customer needs.

Below are the Top 5 picked from our own survey to learn more.
Server's stable operation, security, price, quick response, and data center location seem to be important values.
What do you think is most important in a dedicated server??

Please feel free to share your opinions and reasons. I would appreciate it

Please do not post your results if you use old Unixbench 4.x version. This thread is only for UnixBench 5.1.2, the latest UnixBench version, one that is SMP aware.

The old server benchmark thread in WHT is filled with non-sense results, most, if not all 136 pages of them. Part of the reason is, I believe, the version 4 of UnixBench is not meant to be used on the multiple CPUs/cores environment, pretty much standard on today's servers.

The old Unixbench 4.1-WHT variants produce poor results, especially on Xen environment.

Please do not post any further on that old thread. Do not contribute to further confusion caused by that. IMHO, most, if not all, results on that thread should be discarded.

This thread is meant to be the replacement. Please only post your test using UnixBench 5.1.2. I am posting the original un-modified version. Let's keep this original version in tact.

Simply execute the following command:

tar -zxvf unixbench-5.1.2.tar.gz
cd unixbench-5.1.2
make
./Run

or, if you want to disable file-copy tests, execute the following command (instead of ./Run):

./Run dhry2reg whetstone-double syscall pipe context1 spawn execl shell1 shell8 shell16

Please also note that this 5.1.2 version will make two runs. One run will test only 1 core (1 parallel copy). Another run will test all the available cores (e.g., 16 parallel copies for 8 CPUs with HT).

I am going to post the first "official" result.
