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.

Cut VDI CAPEX by 50-75%

http://www.atlantiscomputing.com/products/atlantis-ilio/

Cut VDI CAPEX by 50-75%

  • Use Less Storage—cut the amount of VDI storage required by up to 90%
  • Scale VDI Storage—support 5 to 10 times the number of desktops on the same storage with equal or better performance
  • Use Any Storage —use lower cost SAN, NAS and Local Disk (SATA, SAS, SSD)

Boost VDI Performance

  • Desktop Performance—make desktop boot, login, and application startup perform faster
  • Accelerate Application Virtualization—accelerate virtualized applications for VMware ThinApp, Microsoft App-V, and Citrix XenApp App Streaming to improve logon times for non-persistent desktops and launch times for virtualized applications

Inline Deduplication

Atlantis ILIO transparently offloads write operations before they reach the storage fabric.

  • VDI Storage IOPS Offload—up to 90% reduction in IOPS load on storage infrastructure
  • VDI Storage Capacity Reduction—up to 95 % reduction in disk storage capacity requirements
  • VDI Latency—accelerates VDI performance by eliminating disk write latency

Windows NTFS Protocol Layer Processing

  • Hyper-efficient IO characterization—instantly characterizes IO based on Windows NTFS file system characteristics
  • Faster IO Processing—real-time IO processing locally from memory
  • IO Optimization—re-sequences read/write operations from small random IO to large sequential

Integrates with Leading VDI Solutions

  • Certified Interoperable—VMware View Technology Alliance Partner and Citrix Ready Partner
  • Leverages Existing Infrastructure—VDI brokers, application virtualization, profile virtualization, and image layering tools
  • No Desktop Changes—doesn’t require an agent or any change to the desktop image
  • Deployed Using Open Virtualization Format (OVF)—easily installed in 8 minutes as an .OVF virtual appliance
