Does anybody have any idea where I can find any paper or article about the costs of downtime of servers? Luca, There is nothing specific, if you think about it, it all depends on the company that is loosing: a.) productivity (how many more people do you need in accounting, marketing, sales, to do the same job with out the server? b.) sales revenue (lost sales because the order desk keeps saying "my computer is down" instead of helping the customer) C.) customers (pissed off clients because they keep hearing "my computer is down" instead of getting the help they need) d.) production (stop building/ordering products and loosing more sales because you don't have the supply, because some order desk clerks forgot how to read and write with out their computer. Maybe production will have to put in over-time to catch up) e.) safety reporting (resulting in injuries) f.) delivery/dispatching (resulting in liabilities to clientele) What else do your servers cover? This is going to be different for every company; a server doesn't cost anything to be down, it's what a company could be missing out on that is costly. So, you see, it's up to you to point it out to your company, you need to write the paper yourself, from scratch. Start with a list of what your server provides, who in each department utilizes those services, and what would it cost to do it with out, for the short term and the long term. Now you want to know if the cost of running Windows Servers (high downtime, lots of reboots, huge licensing bills, but sysadmins are accounting staff that push the on/off button and change backup tapes, forget about security and stability) <=> the cost of running Linux/BSD (low down time, very little reboots, fewer licenses, but paying serious consultant or full time SysAdmin to maintain a secure and stable network). How serious is the business and what is it's data and uptime worth to them. That's how good SysAdmins gets what they want. :) -- Scott - : send the line "unsubscribe linux-admin" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
