White Paper - Understanding and Mitigating VDI Downtime
Downtime in virtualized desktop and Server Based Computing (SBC) environments can be a beast to measure, let alone mitigate. I wanted to tackle this important topic because downtime—in its many forms—affects user productivity and user experience. End user experience— productivity, application response time, flexibility—with the virtualized desktop environment is critical to the success of the VDI project, but is also critical to the business. This is reason enough, but downtime can affect hard-to-measure parts of the business like reputation and opportunity.
The average cost of downtime is $5,000
In this paper we look at the dimensions of downtime and survey other research on the topic. I make a conservative statement that the average cost of downtime is $5,000. Trimming 20 minutes of downtime could save your organization $100,000 per year.
One key to preventing downtime is to stop relying on end users as monitors of the VDI environment. End users’ subjectivity becomes IT’s nightmare. Without actionable data on performance, IT is in reactive mode chasing trouble tickets.
The cost of downtime can be measured by three areas of impact: Productivity lost, damage to reputation and opportunity.
Get a clear picture on VDI performance
The measurements taken by most monitoring tools don’t always paint a clear picture of the performance of a system. Most tools can report high CPU usage, but it’s not always clear what that means. High CPU usage on a session broker may be a non-issue, as most interactions with the broker last less than a second, it’s likely not a large bottleneck on performance.
High CPU on an SBC/Remote Desktop Services (RDS) computer might mean all users on the system are experience a degraded performance, but it might not be indicative of anything other than a highly efficient, well-sized system that is delivering a great user experience for all users on the server. Relying on performance counters to identify outages will likely result in a lot of false positives, where administrators are notified of high levels of consumption, but without any indication of whether users on the system are actually impacted.
Login VSI can help organizations optimize their VDI environments with realistic, real world workloads. When used as part of change management, Login VSI helps prevent downtime due to unexpected impact from updates and patches. Login PI used in the production environment notifies administration when there is a likelihood of unacceptable end user desktop performance. When used in combination, Login VSI and Login PI more than pay for themselves by preventing downtime.
