ZFS capacity calculator

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 options.

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

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

Looking 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 parity.


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.

Enterprise Cloud Infrastructure for Dummies

After the extended summer holidays of the eStep Blog, this eBook seems like a good start to catch up again after the long break. It serves quite well as a starting point to talk to customers about the Cloud and gives a good overview about different types of clouds with the example of Oracle products involved. However, the main focus of the eBook is IaaS, Infrastructure as a Service, which is also part of Oracle's Cloud offer.

Here, you can download the eBook - Oracle Special Edition.


As a new writer in this blog, I'd like to take the opportunity and introduce myself. My name is Patrick Wurst and I grew up in southern Germany, where I also studied Business Informatics at the KIT. Based in southern Spain, I'm working in a Back-Office Systems PreSales Consultant Role for Oracle EMEA since one and a half years ago.

OpenStack: A starting point to learn more

Most of you have heard about OpenStack and the annouced integration into Oracle Solaris 11.2 and about OpenStack support for Oracle Linux and Oracle VM.

These are two good reasons to start to learn more about OpenStack. Ronen Kofman starts a series of articles on his Blog (Ronen Kofman's Blog) to provide more knowledge regarding OpenStack.

First article of the series is called: "Diving into OpenStack Network Architecure - Part 1".

You are invited to follow Ronen through his articles where he shows how the different pieces come together and provides a bigger picture of the network architecture in OpenStack.

CMT Blog: Virtual IO gets better for LDoms

As we all know virtual IO is of great use in the IT environments of today but when it comes to performance we often have to pay the price.

In his Blog entry Improved vDisk Performance for Ldoms, Stefan Hinker explained how the new implementation of the vdisk/vds software stack in Solaris 11.1 SRU 19 (and a Solaris 10 patch sortly afterwards) significantly improves latency and throughput of the vitual disk IO.
