storage review and management

[iz_1]

Hi There,

I am doing a review on storage to plan for future storage needs on my VA. But, I need to ask my users a couple of questions before I can size them accordingly which will include trends.

I have drafted some questions based on know-how (experience) and Admin Guide, but, the Admin Guide that I have is not good enough. I have done some research in the web but did not manage to get good reference or guide for me to post questions to my users. Area of my interest is on storage more than performance to plan for future storage requirements.

Can someone help?

Thanks and regards,

Hello

Off hand following factors need to be considered during sizing:
1. Quantity structure estimations for transaction volume.
2. Number & type of application components.
3. Number of active users.
4. Typical workload profiles (worload peaks and troughs)
5. Expected throughput of core transactions.
6. Recovery windows and backup times.
7. High availability (RAID etc)
8. Future business trsnactions growth.
9. Take care of Development & testing as well.

Specfic Question may include:
- How big is each disk?
- How much disk space is usable?
- Are the disk interal or external?
- How many controllers? Disk-per-controller ratio?
- What are access times / seek times / rotational speed / transfer rates and latencies?
- What is the disk MTBF (Mean Time Between Failures)?
- Are the disks hot-pluggable?
- Is the disk solution open?
- RAID / Stripe Size Questions?

Above all BUDGET?

Thanks.

Thanks.

There is a good book title "Oracle 24x7" by Venkat S. Devraj which may help you.

More impportantly your hardware vendor should be able to help a lot in sizing storage requirments.
