TryStack ARM Zone, One Week Later…

It’s been one week since the announcement of the new TryStack ARM zone and the response has been overwhelming. For those of you that missed the news, last Wednesday, a few of us from the OpenStack community came together to stand up a new ARM-based server cluster, with the intent of providing access to real ARM server hardware for software developers and others interested in finding out more about this new class of machines. Since it’s opening, the ARM zone now has:

  • 251 registered users
  • 139 active users
  • 454 instances created to date

Not too shabby. And those numbers continue to grow every day. (The TryStack community at large is now at over 3500+ members in the Facebook group.) It’s not too late to participate. You can still sign up for free access to these OpenStack environments. Details on how to get started can be found here.

So what’s next?

We will soon begin to actively solicit feedback from the community, especially those who have taken these ARM servers for a test spin. If you’ve been actively using the ARM TryStack zone recently, leave us a comment below and let us know what you’re doing on the system and you overall experiences with the system. Maybe you’re porting applications, or just trying to understand how ARM servers are similar/different from your traditional servers – whatever it may be, we’d love to find out more!

To make it interesting, we’ll send the first 10 commenters (with legitimate usage/experiences) this “Early Adopter” t-shirt for free! (US-based residents only, please.)

Update: Some folks have expressed needs for access longer than 24-hours, or the use of multiple nodes simultaneously.  If this applies to you, leave us a comment and a way to contact you (or send us a note on Facebook) and we’ll get back to you as soon as possible!


  1. We are porting our distributed software “CEN” to ARM and Trystack is and will be of great help for us

  2. Any news on “We hear you about Facebook and we’re working on adding other alternatives, too”

      We’re working with the TryStack volunteers on this as it’s all new code. In the meantime, if you’d like feel free to leave us your email address and we can maybe work something out offline (at least for the ARM zone).

  3. Hello, I’m testing TryStack ARM Zone. Everything is OK, but I/O disk is too slow. What kind of disk setup you’re using for this zone ? BTW, I also want to access longer than 24hours. Thanks in advance.

    P.S: I’m “Hien Phan” on Trystack facebook group.

    • John Mao says:

      Curious to find out more about why you think the I/O is slow…those systems should hav SSD’s attached. Please send us a private message telling us some more details of your tests and what you are trying to accomplish.

    • John Mao says:

      Thanks Hien for your help. For everyone else interested in this topic…the reason for the lower than expected storage performance is because of the way we have OpenStack currently configured to map AMI images to the instances (via Linux Containers). Because the guest instance’s image is being mapped through QEMU today, read/write performance will incur a performance hit as expected. We’ve confirmed that the I/O performance of the host system does not have these issues and is measurably faster.

      One more reason we are working with the OpenStack community to get bare-metal provisioning in place! 🙂

    • John Mao says:

      Oh, and as a reminder to everyone – this is shared infrastructure, so you should consider any benchmarks you run on TryStack will be misleading and most likely under-estimating the actual performance of a native system (as illustrated by this very example).

  4. I am ready to buy the Viridis. I use Ubuntu 12.04 on my non-ARM servers and have actually used multiple ARM5 cores for a 60TB NAS. The research for that was how I found Calxeda. I had put together a Supermicro chassis low power 2U last year using 70 watt CPUs and 8 ssds. The data center has very high charges for extra power. Am anxious to obtain the Viridis for a more professional package than my cobbled together ARM5’s and be able to run Ubuntu vs the ArchLinuxARM (which is also quite good.)

  5. Great job to the Calxeda team. A special thank you to you John. Glenn
