It’s an exciting time in the world of HCI. More and more people are starting to realize the benefits of consolidating their environments down to a smaller footprint. Today, SimpliVity is taking that a step further and cranking up VDI density to 11! Building on the momentum of the OmniStack 3.0 release, a new software update greatly improves the time to deployment and performance of VDI workloads while maintaining predictable results as you scale. While you can read the full announcement here, I want to highlight a few of the results:
- 1000 linked clones in 4 nodes
- 1000 desktops in 70 minutes
- 1000 logins in 1000 seconds
These are some pretty bold claims, and to back that up, they are all validated by LoginVSI benchmarks!
1000 linked clones in 4 nodes
So before I dive into these claims, a little background information about the environment. These tests were performed on the all new OmniCube CN-2400 platform. This platform give a 15%-20% boost over the CN-2200 and brings the Intel Haswell chipset to a lower cost solution. As with all the OmniCube offerings, RAM and CPU are adjustable to fit your needs. 4 of the CN-2400s were placed in a cluster and each were given 384 gigs of ram. As for the different type of VMs used, they were based on the industry standards for Task Worker, Office Worker, and Knowledge Worker. Using Windows 7 64 bit, they were given 1 gig of ram, 1.5, and 2 gigs respectively. So lets take a look at the first claim. Loading 1000 desktops into this size of an environment delivers unheard of density in the HCI space.
1000 desktops in 70 minutes
One of the major stresses on a VDI environment is the amount of time it takes to provision desktops. Whether you are deploying a new OS, refreshing the existing image after an update, or bringing up your environment after a disaster, users don’t want to have to wait around to get access to their work, and likewise administrators don’t want to spend all night doing maintenance (IT admins need sleep too!).
As you can see from the graph above, the number of linked clone desktops scaled up linearly as they registered a desktop check-in in the Horizon View logs. Performance of the virtual desktops did not take a hit either as the number of instances increase as seen in the graph below.
1000 logins in 1000 seconds
Login storms, love them or hate them, it’s a part of doing business. Every morning, users all login around the same time, and infrastructure needs to be able to handle that. For this test, SimpliVity wanted to see just how much load could be put on the system during a scenario such as this, so the login time was adjusted to occur every second (a 2.8x increase over the industry standard for testing) which means that by 1000 seconds, all 1000 desktops will have performed a login.
I think the results here speak for themselves. As the number of active sessions increases, performance remains steady and well below the threshold where users would see problems.
The full results of all the testing is posted here. I’m really excited by this development and can’t wait to see what can be achieved in the future.
