This is a post originally written for the company blog — posted here for posterity.
In the IT industry, the phrase “we are pretty much a 100% physical shop” is one that you dread to hear – especially from a fast-growing company. Such was the case with a leader in the financial services industry recently when they asked Sentinel to install a Virtual Desktop Infrastructure (VDI) solution for a new call center rollout of around 250 desktops as well as fully re-deploy their physical desktop and server infrastructures. They were pretty set on a hyper-converged solution and were looking for something scalable and easy to manage. To be successful, in the eyes of the business, the solution had to:
After reviewing the vendor options, the customer ultimately chose Cisco HyperFlex and VMware Horizon for their hyper-converged VDI solution. Aggressive deployment timelines were set and equipment was on the way. From there we moved onto the fun stuff.
The HyperFlex cluster was delivered quickly. Really quickly. Once the gear was on-site it was time to deploy. Before we go there, I want to touch on one particular aspect of the solution. Sentinel knows that maintaining data integrity and availability is essential to our customers as they adopt and adapt to new technology. How the Cisco HyperFlex solution delivers that can be summed up pretty easily:
Back to the deployment. In a post on my personal blog, I mentioned that the HyperFlex deployment was pretty fast. Once you rack and cable the cluster, the HX installer is a breeze. What I love about the HX installer is the fact that it really does build the entire UCS deployment and makes adding a node to an existing cluster just as easy. Click. Click. Done. Overall, the deployment of the HX system after rack and cable took less time than installing the vCenter server that was required for the deployment (Note: The vCenter must be on separate hardware but can be moved into the HyperFlex cluster for ongoing operations).
After meeting the first two objectives, we needed to look at the speed. Since this was a VDI cluster, we made one small change (one line in a configuration file) to optimize the cluster’s L3 Cache for a read-heavy environment. Once that small change was made, it was time to run some tests. Since Sentinel doesn’t own the environment I will only include the following observations:
The customer was extremely happy with the performance, scalability and easy management of their new infrastructure. The Cisco HyperFlex and VMware Horizon solution met the requirements so well that I better understand the hype around Cisco HyperFlex and the SpringPath HALO Architecture.
Of further interest in terms of scalability comes confirmation from Cisco that node capacity expansion beyond the current self-imposed limitation is in the works and will not be limited to hardware. External storage is also fully supported. This means you will have the capability to hyper-converge your core systems and still make use of external storage area networks (SAN) where business needs dictate.
All in all, HyperFlex is a rock solid platform with a fantastic and robust architecture that you would be wise to evaluate. Couple it with VMware Horizon for desktop deployment, and you have an infrastructure built to help your business achieve unprecedented levels of success.
