Project manager for VMware – Hyper-V and VNX infrastructure - SharePoint infrastructure migration from 2010 to 2013

Intrasoft Intl. ext. consultant for DIGIT A2 European Commission Address: Luxembourg, Luxembourg

City: Drosbach

Country: Luxembourg

My main tasks were troubleshooting issues with the VMware infrastructure and the EMC VNX5300 storage. The issues identified were hardware as well as software related and resolved adequately.

An attempt was made to upgrade the VMware VCenter server from 5.1 to 5.5 earlier this year with no success since there were issues with the SSO and the complex AD of the European Commission with many groups and subgroups – issue that has been later identified and resolved by VMware with their latest release. Brocade Fiber switches required proper zoning and all of the hosts in the Hyper-V infrastructure their “host agent” properly installed and configured. I had to install and document the procedure of a Hyper-V cluster with 3 hosts and provision storage from the VNX5300 as well as from their iSCSI HP MSA SAN storages. Daily tasks: new VM’s provisioning for the various teams, backup maintenance of the VMware infrastructure, monitor and keep updated the VNX5300, provision new storage. Assignments: plan – document and implement the migration of their SharePoint infrastructure from 2010 to 2013 in a three tier VM system. Working environment: EMC VNX5300, HP servers (G3, G5, G6,G7 & G8), HP Blade enclosures C3000 & C7000, Brocade FC Switches, HP MSA iSCSI storages, IBM servers, IBM Flex systems, VMware 5.1, Hyper-V, Windows XP-7-8, windows servers 2008 R2 – 2012.
