here is the specs that we have decided to go ahead with...

around 30 apache servers+php+memcached

Dual opterons 2.4 Ghz with 4 GB of RAM each

and 10 Database servers, running MySQL
Dual OPterons 2.4 GHz with 8GB of RAM each

All servers would be running SuSE 9, and we would be implementing application and OS (LVS ) level load balancing.. we expect a transfer rate of around 4.5 Tera Bytes per day on the average

few questions about these configurations

is it necessary for apache serves to be high end as well or can we go with a lower spec machine ? coz we will be considering the option of compression for higher tranfser rates...

and secondly .. we have been getting reviews from hosting companies about heating issues with Opteron, and the price shooting far more than Dual Xeons if we get the cooling units instaled for them....

The reason we want to go for OPterons is that according to the reviews on , and, we have seen OPteron outperform Xeon both as webservers and database servers.

and lastly. recommendations for a goood hosting company, we intend on going for non panel, un managed servers, with a *good technical* support, i know the levels of managed and un managed varies from company to company, but i'm looking for sumone who is willing to go the extra mile to help us in case of problems and such stuff..
