Marc Cohen's initial analysis proved the reliability,
service, quality and ease of configuration of HP
products. Today, there is a fleet of 30 physical HP
ProLiant DL380G5p servers managing all the
applications for the municipal services, apart from
the design office (which has workstations and an HP
server). Many of the fleet servers are connected to
250 HP Thin Clients distributed across 20 communal
buildings by means of an Ethernet network. There are
more than 50 industry-specific applications, plus
administration functions, which are now accessible
from any workstation. 
Financial and technical benefits
“Thanks to this solution, which involved ‘virtualising’
the workstations, we were able to first estimate then
achieve a saving of €150,000 per year compared to
installing 300 PCs, a third of which would have to be
renewed every year,” explains Marc Cohen, “not
forgetting that an HP Thin Client was and remains
much more affordable than a PC. What is more, the
HP terminals are extremely flexible, with simple,
customisable updates using excellent administration
tools.” As soon as they connect, all users can access
a user-friendly Windows environment and
applications as a function of their access
permissions. The result is that IT support for the thin
clients is considerably reduced and adding an
industry-specific application is merely a question of
updating the fleet of servers.  
Marc Cohen emphasises that “we can also take
control of a workstation remotely in conjunction with
the user if they have a problem with an application,
or close the terminal if they are not there, all from our
administration console. Finally, in terms of the
environment, which is something very close to the
town's heart, Thin Clients consume considerably less
energy than PCs: 30 W compared to 200 W, which
has drastically reduced the electricity bills.” 
Thin Clients for schools
As the use of HP terminals at the town hall was a
success, the idea came about of deploying them in
schools. This made sense as the public office was
responsible for IT support for the existing PCs and
they had to be returned to the town hall for reasons
of costs and equipment becoming obsolete. For Marc
Cohen, it is very simple: “if we want the schools to
have the same tools and the same internet access
with a minimum of IT support and security, we need
to apply the same principles as those in force at the
town hall.” As a result, each of the seven school
groups in Rosny-sous-Bois now has a dedicated
computer room with an HP ProLiant DL120 G5 server
linked to an Ethernet Local Area Network (LAN) with
15 HP t5730 terminals. 
Each server is installed with the HP Image Manager
application, which allows each workstation to be
displayed virtually. As soon as it is switched on, it
goes to the server to find its personalised
configuration, which cannot be changed. If there are
problems, the terminal merely needs to be rebooted
to restore it to full working order. These updates are
carried out remotely on the dedicated classroom
servers from an administration console managed by
the IT team. 
There are now more than 100 Thin Clients installed
in the schools, and no physical intervention is
required. Because of the savings made, the number
of Thin Clients can be gradually increased in the
computer rooms from 18 to 20 terminals, not to
mention the increasingly high-performance
peripherals. There is also a central filtering 
solution which prevents the children accessing
banned sites.
Working towards a web-oriented environment 
In 2010, Marc Cohen, who now heads a team of six,
will be carrying out a comprehensive migration of the
technical architecture. The users of the HP Thin
Clients at the town hall will use an intranet and a
web interface to open ‘applets’ corresponding to the
industry-specific applications. The HTML environment
will considerably simplify the use of the computer
system. Not only that, but some of the physical HP
servers in the computer room will themselves be
virtualised in order to increase their processing
capacities without the need for a user interface and
the additional electrical energy.
