Infrastructure Support – Virtualization

Challenges:

Limited documentation
Application dependency on lower versions
Lack of automation for basic tasks
Limited monitoring capability

Solution Approach:

Creation of new VDI’s, installing Citrix applications and assigning them to users as per the service desk request.
Monitoring Citrix internal and external environment using Citrix director and assisting Service Desk and NOC people for basic troubleshooting.
Handling issues related to VDI and applications connectivity.
Working on Citrix printing issues in various environments.
Resolving complex issues in NetScaler, Citrix controller and its components to reach SLA.
Reclaiming VDI’s which are not in use and decommissioning them with Service desk approval.
Troubleshooting slowness/connectivity issues for the users.
Resolving profile corruption issues and giving access to the shared folders/paths.
Organizing and maintaining environment with zero downtimes and doing daily health checks on the vcenter about the resources utilizations and taking actions against the alarms and alerts.
Deploying and configuring the VM’s with given time lines and putting them on the basis of resources availability.
Creating / configuring / mounting and unmounts the data stores if required.
Upgrading and patching the hosts with the latest releases before creating the run books for the release notes and effects on the environment.
Preparing new host profiles and duplicates for the troubleshooting / resolving and compliance check for the sub tasks, Device Configurations, PCI slots and issues with vmbha’s and nics.
Creating of new clusters and placing new hosts into the clusters with the vDS / NFS and iSCSI networks mappings with the provided networks.
Validating the hardware and configurations of the hosts before putting them into the clusters and doing the network configurations such as Host Vlan, Mgmt. Network / vMotion / NFS / iSCSI and FC.
