which means:

- dedicated CPU, 32 cores
- 16GB RAM
- SSD HD, integrated raid

calguns will be good for 2 years after that...

OR

split the servers into small virtual, most optimal.
- 4 core for forum
- 8 core for DB
- 4 core for images

In the second option, you wil lbe able to see what needs more juice and upgrade accordingly instead of one mondo upgrade..

2005 called... to tell you to put the crack pipe down.  16GB ram is about 10x less than what this place needs.

Okay what about 2 TI 83 graphic calculators linked together with that special cable?

Even with a dedicated server, split the front end/backend intwo two virtuals.
PHP s/w on frontend and DB ( guessing its mysql) on backend.
This way, you will know what is chewing CPU and if you need to split again, it wil be easier.
Just IMHO.
My 16GB comment was a typo, 512GB. Also make sure they are not saying 4 cores but have hyper threading turned on which is essentially 2 cores faking as 4.

Hi All,
You are all missing a piece.
A two disk RAID1 is never going to meet the needs.


As a guess , it will require......

Dedicated RAID controller (with Cache)  -  You don't want to be pulling main CPU cycles to maintain the RAID.
RAID1 - OS
RAID1 - DB
RAID1 - Indexes
RAID1 - Pictures
Hot Spare

Total 9 Drives.  Minimum (Assuming you don't go with RAID 5 or 6 or add a drive for the logs)
And depending on the software/user usage patterns maybe more.

3.2GHz proc 8 core will just be strangled on a RAID1

Even virtualized wont get you around the need for dedicated physical drives.
You can't avoid needing more drive heads to read more data.

SSD's can help, but large spinney disks are cheaper.

Hell, I should do this for a living... Oh, that's right I do.

Plus don't forget adding RAM in pairs is old school when looking at real Servers.
You may need to add RAM in 3's or as in my latest Server multiples of 8

Why would RAID drives be needed when the entire website and database can be placed into DRAM memory?  Kes had stated earlier that even 16GB of DRAM is enough.

Not to mention that the physical 'disk' memory of the server is on SSD which should be way faster than any RAID system as well.

I still think the bigger problem is nearly 2000 web crawlers attacking the site.  Access to forums should be LOGIN ONLY to get rid of them.
