ZFS capacity calculator

Adrian Pruna
Business Analyst

As a presales, one of
the most challenging and yet interesting activity was to size customers storage requirements.

I saw the first smart
array card when I was in my first year of college and at that time I only
knew that RAID 0 can greatly speed up the performance of an operating system by writing the bits on 2 disk drive simultaneously.
Only when I started my first job as a configuration expert I learned that
actually this is an industry standard that was around since1988.

When I started my
presales job with Oracle I had to face for the first time the software RAID-Z
that our storage was using. I realized then how important it is to calculate the usable capacity the customer will have based on the various RAID-Z levels, especially when there was no tool that allowed us to achieve this in an easy way.

Luckily some of the creative mind within my team (Marius Ghergut and Adrian Topa) found a solution to cover the tool gap by developing an excel based simple solution that allows us to calculate
the ZFS Storage Appliance storage space based on different configuration

They called it ZFS raid calculator and you can download it
from Oracle

(If you are not
registered on Oracle HW TRC, click
here ... and follow the instructions.)

towards the datacenter move to cloud strategy, the software RAID is the
technology of the future, as the storage cloud provider will have a big enough
array to move the parity from the conventional bit parity to the new data/block


As this is my first blog post I will also
take this opportunity to introduce myself. My name is Adrian Pruna and I lead
one of presales team in Oracle. Apart from various tools and new technology announcement
I will also share with you my personal learning journey from an on premise
expert to an infrastructure cloud expert.
