At this site, UTH systems were primarily deployed with Citrix Provisioning Services. Worked with various groups including application teams to optimize performance while others on teams focused on Office 365. The environment was composed of two Netscaler VPX200, 44 node Nutanix cluster and Citrix XenDesktop 7.6. Additionally, we supported a XenApp Site on 7.5 which hosted specific applications which required 32bit OS or older add ons.

Design Architect and lead implementation of two-phase migration of 1400 guest servers from VMware 5.0 through 5.1 and finally to 5.5. The project included hardware refresh where HP was replaced with Dell and upgrade of underlying VM ESX. Before leaving the team completed a full migration to ESX 6.2 to take advantage of enhancements in site to site live VMotion and virtual storage (EMC Vplex) high availability. As part of this, we are enhancing the license pack to ESX Enterprise Plus, and taking advantage of the feature set included in that mix.

VRealize Suit Automation Center and the role of VCenter Orchestrator workflows that delivered a quicker turnaround of computer systems.

Architected profile management solution will not only simplify BYOD policy but also unify Desktops across four management teams by deploying Citrix XenDesktop. Utilizing VMware 6.0 with XenDesktop 7.11 we will reduce access time for medical professionals by 15% over older Citrix technologies. With this migration we will be utilizing MCS instead of PVS, for XenApp targets hosting 8 Electronic Health Care packages as well as Medical Billing and four PAC tools archiving medical images and other health care documents.

The team has this year embarked on supporting application virtualization around Microsoft’s App-V 5.1. With this project we have stood up two App-V farms which allow us to provide the desktop teams as well as application teams a development farm to package and test virtualizing the deployment of their client components in a “non-production environment” before our team migrate to a production App-V farm and deliver the application to end user devices or Citrix XenDesktop 7.11.
