What is Diskless VDI?

Diskless Virtual Desktop Infrastructure (VDI) is the concept of using local server memory in combination with storage optimization software to store virtual desktop images instead of shared SAN/NAS or local SAS/SSD storage.

By storing virtual desktop images on the local memory of the hypervisor where the desktops execute, response time are faster than even the most expensive local SSD drives (MLC or SLC), cost less when combined with Atlantis ILIO, and increase reliability.

With existing VDI architectures, virtual desktop images are stored on either shared SAN/NAS storage or local SSD disks, which are costly, have limited IOPS for write-intensive VDI workloads, can have a limited lifespan and consume more power than memory.

Benefits

  1. Software only – Atlantis ILIO Diskless VDI is a purpose built storage layer to run virtual desktops with just CPU and RAM and no other storage or SSDs. Scale-out VDI infrastructure with just servers and software.
  2. Amazing user experience – 300+ IOPS/user* – faster than PC user experience  even with iPads.
  3. CAPEX below $200/user – infrastructure cost under £125 per desktop including the server hardware, RAM and Atlantis ILIO.
  4. Lower OPEX – Enable lower operating expenses by eliminating rack space, power consumption, cooling and repair costs, and daily operational tasks of maintaining disk-based storage.
  5. Automated multi-rack deployment – Automatically install and configure ILIO on hundreds of servers across dozens of racks. Creates and registers NFS data stores that are ready to use by the VDI broker to complete the provisioning process.
