Virtual Desktop Infrastructure
Note: Due to Non-disclosure agreement, the client company name as well as various technical detail of the project cannot be disclosed.
Reduction of the IT manpower
The project had multiple goals. The client aimed at:
Reducing the IT help desk manpower
Diminishing the electrical footprint of offices
Increasing the overall up-time of employees workstations
Providing an itinerant workstation for “mobile” users
Integrating any existent software including several ancient in-house financial projection solutions
Using existing hardware to reduce overall investment
In order to answer the client expectations, we decided to stay away from Citrix products and choose a more recent solution from Ncomputing. Mixing the versatility of the Ncomputing L300 and the robustness of Microsoft Server Hyper-V, we designed a thin client user workstation infrastructure running on local virtual machines stored on several NAS.
Powerful Virtual Desktop Workspaces
Ncomputing L300 devices and VSpace server allowed us to use a ratio of one virtual machine for 20+ thin clients, reducing de facto by a factor 20 the number of machines under IT supervision.
Microsoft Hyper-V combined with Fusion-IO data acceleration card gave us the necessary edge in I/O performances that opened up the possibilities to proceed to maintenance tasks and snapshots of the virtual machine during working hours without affecting the end-user experience.
In addition Fusion IO allowed to:
Remove I/O constraints faced on similar projects
Maintain high performance workloads while maximizing server density – 20 end-users per Virtual Machine and 7 Virtual Machines per Dell 420 servers (ratio of 140 users per server)
The extreme performance achieved with Fusion IO and easy integration with Hyper-V allowed us not to use an entry level performance SAN by moving all the active files onto the flash memory of Fusion IO
