Title: Senior Infrastructure Specialist. Ahold has outsourced their whole automatisation by EDS. Most servers and network components from the server rooms in Zaandam are transferred to the EDS datacenter in Russelsheim and e-shelter in Frankfurt. My task in the datacenter migration project team is the implementation of Platespin Powerconvert for migration of servers to Vmware ESX and to other/new hardware. This is done by a fixed connection from Zaandam HQ and KA to the EDS datacenter in Russelsheim and e-shelter in Frankfurt. Some challenges we challenged during the migration of the servers: Migrate to another type hardware, to another brand of hardware, or to an other platform as Vmware ESX. During the migration of the servers I was stationed in Amsterdam Sloterdijk, together with all Ahold datacenter move project members were stationed. After the most servers were migrated I was physically present at the location Russelsheim and Frankfurt to ensure that ongoing and new servers requests were handled in good order. Another task was increasing open service requests which needed to be completed, this in co-operation with mainly German EDS Colleagues within the required standards and regulations of EDS. Also to inform, to delegate and instruct my German colleagues at new coming and open service requests which were part of my daily tasks.
