capacity planning

I am not sure which question you are asking. Are you looking for some specification that will recommend the amount of excess capacity you should maintain? Or, are you asking for something that will monitor your system and alert you when you reach the limits that you have set?

The first question is very hard to answer. It depends on many variables. The second is very easy to answer. There is a freeware package called Alert Monitor. It works on a variety of platforms.

1. Access the current diskspace. Used and free space.
2. Estimate the annual growth of the enterprise.
3. If your file storage is on servers allow 20% free space for optimal disk use.
3. Add 10% for error.

Add it all up an that is your disk space capacity plan for the next year. You will have to determine if you need to acquire more servers or just increase the capacity of existing ones or if you have NAS or SANS just add the space there.

Good Luck,

Trish
