Server choice... RAM or CPU power?

Post by meteo-melin » Mon May 18, 2015 9:07 am

Hello folks,

I'm planning to run EMS for a little domain (Belgium or BeNeLux) but with a resolution of 1km, probably 2 times a day , 30 hours in the future.

Between those two servers, which one should I chose?
- Core i5-750 (4c/4t 2.67GHz) - RAM 16Go
- Intel CR2750 (8c/8t 2.4GHz) - RAM 8Go ECC

I know, this is not very powerfull but I want the system the cheapest possible.

Maybe this is not possible to run EMS on those servers?

Thanks.

Hello,

first one will be able to run WRF, though I don't know what is second one (google also doesn't return anything meaningful) so I can't compare them.

Thank you for your answer.
Here Intel's info about the second CPU http://ark.intel.com/products/77987/

Btw, it C2750 and not CR2750... Sorry about that.

I guess they are pretty much similar in WRF performance. There is no info about instruction set extensions of that Atom. I never used those CPUs so if I were you I would go with older but well known I5. But, current i5 systems are way faster than this one. If you can afford one it would be best solution.

Not easy to find servers which are not too expensive...
It stays a hobby...

Do you look for leasing hardware or having your own purchased?

Leasing.

Those servers are from Kimsufi and Online.net.

I would say 20€ without VAT.

I think I'll start with something not too powerfull and then, once everything is running fine, go on a more powerfull system like KS-4 (I7-920 16GB RAM).

Btw, I use that server for some low traffic websites.

Take a look here:
https://robot.your-server.de/order/mark ... orttype/up

You can find i7-2600 for 25€ if you are little bit lucky. It is so much better than all those you listed.
