VDI SLA
The previous SLAs are for server workload. What about for VDI? To me, VDI needs to be high-performance:
- From an employee's viewpoint, if a $500 PC can give me good performance, I certainly expect the same performance on a VDI.
- From a business viewpoint, let's consider a staff salary of $50,000 per year. The total loaded cost for that person will be around $100,000. We calculate VDI TCO every 3 years. For someone who is costing the business $300,000 in 3 years, a 5-percent drop in productivity because the employee is frustrated with the VDI costs the business $15,000. Here is another way of looking at it: if you are an employee, and you feel frustrated with your slow desktop/laptop, does it make business sense to get you a better one?
Based on this, we'd set the VDI performance SLA as shown here:
As you can see, there are other counters that define a high-performance VDI. They are not in the SLA. They belong to capacity, not performance.
You should only include metrics...
