Denna guide kommer jag skriva på engelska för det finns för få heltäckande guider ute på nätet, så jag tänkte hjälpa världen.

The above line is in swedish, telling my normal readers that this post is in english due to the fact that the contents of this article is interesting to a wider audience than what my normal rants are.

I’m going to tell you how I’ve solved the monitoring of my HP Proliant DL 180 G5, although this should work on any proliant server with the HP Smart Array-cards. I’m running Debian Lenny version 501 when this is written. This article will span a couple of different articles which will cover som different topics on monitoring, backup solutions and risk analysis.

To start off, I’m going to talk about risks, and hence I will start defining a table for my active risks, yours should look almost the same, but your consequences are probably going to differ from mine, due to how your buisness is structured.

Risk Assessments

Risk Assessments

Now we need to have a severity scale to later on be able to guesstimate(not a real word, I know) how much impact a risk could have on your environment as a whole. I will be working with a scale from 1(who cares) to 5(file for bankruptcy). So here comes my table:

The chart on the left is just a quick one, and you should sit down with your key persons in your company and start a risk-discussion to know where do we go from here? As you can see, most actions are cheaper than the unwanted consequences, the actions also have the benefit of not being noticed by the customers as blackouts will be. All costs are estimated in SEK. The number 400000 is calculated with company net worth + legal fees for loss of protected data. And those fees are not feasible.

Of course all the above risks are general and all companys will have them, you will also have a lot more risks and if you look into the details of risks, you will for example find the RAID 5 write-hole, loss of redundant disk, loss of spare disk in redundant arrays, enironmental risks such as temperature and humidity. There are a lot to monitor and lot that can go wrong, so be pessimistic about the world and start assessing your risks!

This serie of article will soon be completed by a method of backing up your data to a remote host, linux to linux and mac to linux. See you soon!
