Hey all,
My org has right now dedicated server with i7 3770, 32gb ram and hdd's on raid 1.
I have been monitoring our server cpu and ram usage, on average server uses less than 1 core and max cpu usage is 2.02. So if i understand correclty, 4 core/8 threats, this means that 2 of 8 "cores" has been busy, which leaves 6 cores unused, right? RAM is allso not a issue, about 28 gb is "free". All choises are located at same datacenters, so there is no latency difference.
Because we are planning to upgrade server os to newer version of ubuntu, new server will be needed. So i have few questions:
1) Our mysql database is currently ~1gb and database will be around ~3-4gb at summertime. Because database is so small, is ssd raid 1 overkill for mysql use (because we can allocate enough ram to cache all databases to ram without any problems)?
2) Is i7-9xx enough(CPU benchmark almoust 50% less) for our new server? Or should we stay with same processor, or could we get more speed going with xeon e3?
i7-9xx goes with +16gb ram(48gb), others have 32gb.
So our options are:
1)i7-920, 48gb ram, 2x ent. hdd raid 1 & 2x ssd raid 1(maybe os, mysql and some of the apache-sites?)
2)i7-3770, 32gb ram, 2x ent. hdd raid 1
3)Xeon E3-1245v2, 32gb ram, 2x ent. hdd raid 1
Thank you in advance!

Hi,

---> I would have a concern with RAID because MySQL will have both high read and write processes and RAID will give you high read performance, no doubt but at the same time write processes will be slow.
2) Is i7-9xx enough(CPU benchmark almoust 50% less) for our new server? Or should we stay with same processor, or could we get more speed going with xeon e3?

---> Things depends on what you are hosting and what you will be hosting. You are hosting application currently and you have analyzed server performance for it, so based on that statistics you can decide whether upgraded is needed or same configuration will do the job.

May we know that exactly do you host in a server? It is not possible to tell what is better for you without more information.
i7 - home computer hardware, good for non important data, gaming, data processing. Not a real server.
Xeon E3 - real server, designed to work 24/7.

Sorry, i forget to tell what is our server use. We use apache2, mysql to host pages with php scripts. We allso have low use teamspeak 3 server and allso low use samba server running.
"I would have a concern with RAID because MySQL will have both high read and write processes and RAID will give you high read performance, no doubt but at the same time write processes will be slow."
-> To improve write processes you would recommend mysql without raid then or something else?

Of the three choices you've presented, I would go with the Xeon E3-1245v2, 32gb ram, 2x ent. hdd raid 1. Were you having issues with your current RAID1 setup?

For websites and scripts i7 is good? Not really. i7 prices are lower, processors are very powerful, but i7 boxe isn't a real server. Also, do not support ECC RAM.
I recommend to look at E3 with ECC RAM memory.

I'd suggest E3 & if you've got some budget, go with Raid10 rest looks good.
