QuadStor - An Update

It’s been awhile since I did a post on QuadStor, a now open source storage virtualization product. Since my last post, several new features and changes have been made to this unique storage product. 

QuadStor is now free and under the GPL v2 licensing. This opens up access to the product and allows more flexibility for those that want to use this in your home lab as an example! http://www.quadstor.com/open-source.html

QuadStor has also created a Google group for support questions that is monitored and supported by QuadStor support. They also have a paid support model as well, if interested! 


 A couple notes that I found interesting. When installing Quadstor on a supported platform. (FreeBSD 8.2/9.0 release, RHEL/Centos 5.x/6.x, SLES 11 SP1/SP2, Debian squeeze 6.0x)

  • A resource recommendation is to add 2 GB of memory for every 1 TB of storage, or 4 VDisks, or 2 physical disks configured. Some of the reasoning behind this is that Quadstor assumes ownership of 80% of the total memory of the server. You have to keep this in mind, with regards to the base operating system requirements.
  • Storage pools are a new feature released in 3.0.5. Where different disks can be pooled together like a SSD pool for performance tiering!
  •  QuadStor does not do RAID management. If RAID is needed configure the RAID from the base system used.

I should also note, that I have tested QuadStor with PernixData in my virtual lab, where Pernix gave me the performance and QuadStor was my capacity and data service play!

QuadStor Update Released

QUADStor released Version 3.0.12 today, adding several important features. QuadStor is starting to become very refined and capable of competing with many enterprise storage solutions.

Feature List:

1. Synchronous Mirroring -
2. Disk partitions and Linux LVM volumes can be configured as physical storage
3. FreeBSD 9.0 support
4. Many bugs fixed in the HA and clustering code. Also support for node fencing.

Documentation has been updated in

QuadStor Review

As promised, here is my review of very promising software that has the potential to disrupt the SAN market. I say this, because #Quadstor supports #VAAI and it's free. They are still in beta and you do have to build your own appliance but this is far cheaper than buying a $50k appliance just to get VAAI support. 

They are adding features every month like.... Deduplication, Compression, unified management, clustering, vdisk cloning, vdisk replication and much more.... 

They hope to be out of beta sometime in May or June, but I have been testing the beta version 2.0.45 in VMware Workstation and it works great and the best part is that I get to test VAAI. I'm running it on #FreeBSD 8.2, but you can use Debian, Redhat, SLES and soon Ubuntu. 

I hope to do a part 2 to this post and do a physical install of QuadStor. I will have more details as to performance and my reaction.
