In VDI environments, where hundreds or thousands of virtual desktops retrieve data from the same storage arrays at the same time, sequential workflows are translated to random access and the SAN array quickly becomes a bottleneck. Furthermore in a VDI environment allowing large amount of users to seamlessly boot from the centralized server using a golden image becomes a key performance challenge.

VXL’s cache warm-up scheduler, allows IT professionals to analyze VDI golden images data access during boots and automatically load the key data into OCZ’s Z-Drive R4 PCIe SSD to be available for the users ahead of time. VXL’s VDI data access analysis and cache warming engine places the right data on fash in the server and enables peak loads performance optimization, reduced latency for faster end user boot experience and supports of a larger number of virtual desktops per virtual server.

Solution Benefits

  • Increase the number of users supported by each server in VDI environment
  • Provide consistent performance to users even under heaviest loads
  • More responsive desktop environments for VDI users
  • Better scalability as fast local storage can scale directly with increase in users
  • Incredibly fast boot times for users, even during very large boot storms and heavy loads
  • Very fast generation of clone desktops
  • Lower TCO and increase ROI per user
