- 40. Customer Case Study: Oregon State University High Performance for VDI with Budget-friendly Scaling Challenge ⢠Storage overburdened by VDI workloads ⢠User login took over 20 minutes during peak times ⢠Recomposing VDI environment took 10+ hours ⢠Manual resource-balancing not sustainable ⢠Limited storage budget Solution ⢠Virtual SAN deployed on Dell servers Results ⢠Drastically better performance: user login time reduced from 20 mins. to 1 min. ⢠Increased VDI scale: could support 170+ additional users on existing servers/network ⢠Simplified management: resetting virtual desktops reduced from 10 hours to <2 hours ⢠Lower cost and ease of scale: lowered acquisition costs by 75% and enabled easier scaling for future needs âBefore Virtual SAN, we had no ability to scale. NowâŚitâs a piece of cake; If I want to add additional capacity, I just add an additional server. I donât have to worry about whether my SAN can grow or not.â Alan Sprague, System Administrator Case Study: Oregon State University Video: VSAN at Oregon State University Corvallis, Oregon Academic Institution 26,000 students 40
