By following a few general guidelines and using a phased deployment approach, you can ensure the success of your VDI deployment, no matter how many seats you are planning to deploy.
Over the past ten years or so I’ve watched the approach to VDI deployment evolve and have learned firsthand what is necessary to achieve VDI success. The biggest challenge that VDI faces these days is that there are scars everywhere. Most of you have almost certainly deployed it or known someone who has. For years, it was extremely difficult to get right—initially VMware saw a success rate of 50% at best. If you go back five years, storage amounted to 60%–70% of CapEx. Cost savings, if any, didn’t come until two to three years down the road.
Today, all that has changed. Storage costs are often less than 10% of the total, with most of the expense going to licensing costs. Done correctly, VDI can deliver significant CapEx and OpEx savings—all while giving your employees more mobility and more flexibility.
In this blog, I will explain how to go about planning and executing a successful VDI deployment. I’ll also explain some of the advantages that Tintri brings to the table. In a later blog, I’ll dig a little deeper into some of the nuances of VDI deployment including graphics acceleration.
Before you start planning a VDI rollout, there are a few guidelines worth keeping in mind:
To ensure your VDI deployment goes as expected, it’s a good idea to proceed in phases. Most of the successful VDI deployments I’ve been involved with have used some variation of the methodology below. Once you complete your initial architecture and technology review and have an idea what technologies you plan to use, you’ll want to progress through these phases:
The advantage that Tintri brings to VDI is that it makes storage the simplest part of the solution, so you can just plug and play. Tintri eliminates most of the big VDI problems of the past. A series of blog posts from last summer explored the advantages of Tintri all-flash storage for VDI performance, data protection, and data efficiency.
Because Tintri builds its all-flash storage to do everything at the VM level, it works perfectly for VDI. Tintri performs every operation at the level of the VM or vDisk, making it much easier for virtualization and desktop administrators to understand and manage.
As long as a project is done correctly, storage will no longer be a problem. One long-time VDI manager likes to talk about how, before moving to Tintri storage, it was a full-time job to manage 120,000 seats. Today, the number of seats has grown to 200,000, but he spends just four hours a month managing the environment.
Next time I’ll explain how to go about incorporating graphics acceleration and other technologies that extend your virtual desktop environment.
Unique control with VM-level actions for infrastructure functions including snapshots, replication and QoS make protection and performance certain in production, and accelerate test and development cycles.
