Klinikverbund Südwest is an alliance of German hospitals in the southwestern cities of Böblingen, Calw, Herrenberg, Leonberg, Nagold, and Sindelfingen as well as the Böblingen Rehabilitation Clinic. It numbers amongst the largest municipal health institutions in Germany with approx. 4,300 employees and a yearly intake of over 70,000 inpatients and 170,000 outpatients. Klinikverbund Südwest was founded in 2006 with the objective of achieving maximum patient satisfaction with the best possi-ble cost efficiency. A main factor in achieving this goal is ensu-ring optimal structure and workflow organization, by which IT system performance plays a central role. However, Klinikverbund has a decentralized IT system. A consolidation of the IT landscape became an imperative to ensure problem-free operation: an obvi-ous task for COMPAREX* and the perfect situation to implement innovative virtualization solutions and harmonize the system, starting with the server software and working right through to the hardware.

Treatment in two stages

Changes can make systems vulnerable. The performance of the IT system suffered as a result of different ‘viruses‘ following the numerous mergers taking place within the clinic alliance. This meant that COMPAREX‘s treatment had to tackle several diffe-rent causes and was implemented in two stages. The first priority was to create a scaleable, secure and stable environment that allows decentralized access from the different hospitals. The se-cond step was to relocate the data processing center and to pro-vide a central place for file sharing with a fast network connec-tion to the program. The basis for both of these requirements is a state-of-the-art server and desktop virtualization that also sup-ports the modernization of the clients in the connected clinics.

TREATMENT FOR THE KLINIKVERBUND IT SYSTEMS

Hans-Ulrich GrafHans-Ulrich Graf, Head of IT Klinikverbund Südwest, Sindelfingen

“Our IT treatment project in collaboration with COMPAREX began in April 2010. There were significant improvements to the stability of our IT landscape during the migration from VMware to vSphere. Servers and applications perform substantially better now. Imple-menting Citrix desktop virtualization with performance tuning for the virtual environment as well as the physical Windows systems were choices that paid off quickly.”

IT Infrastructure / Virtualization

IT: STABILIZED, CONSOLIDATED AND IN GOOD HEALTHGetting closer in every way There are further challenges ahead for Klinikverbund Südwest and COMPAREX with their spirit of close cooperation: updating the environment from Exchange 2007 to Exchange 2010 (to improve the LiveMeetings and Messaging applica-tions) and finally the relocation of the data center from Calw to Sindelfingen. IBM XIV was chosen as the new storage system, and a FibreChannel connection will also be installed.

With this kind of support, the clinic alliance is now on the right path to achieving an exemplary, highly-efficient IT infrastruc-ture. Moreover, these improvements in efficiency and fast data provision serve one goal above all: the wellbeing of the patients.

As ‘first aid’ for stabilizing the storage landscape, COMPAREX corrected all the configuration and design inconsistencies and updated the firmware, some of which had already expired. Then came the migration of the VMware ESX environment from version 3.x to vSphere 4, including the porting of the vCenter server. The virtualization environment was consolidated and vastly improved as a consequence of these activities alone. In addition, a backup server that saves the entire virtual ma-chine environment on high-performance hardware was installed. Finally, the desktop virtualization based on the new Citrix XenApp environment (version 5.0) is highly beneficial for the clinic alliance.

To optimize administration of the Windows infrastructure sys-tems and servers, COMPAREX worked together with WITstor to prepare the migration to the Citrix XenApp environment at the clinic group. Tasks here include active directory services and name resolution with WINS and DNS. The anti-virus concept was also simplified through implementation of the Forefront anti-virus software, and three obsolete anti-virus solutions were replaced during this process. Operations in the mail server also required stabilization. This was achieved by installing Service Pack 2 on the Exchange 2007 system and introducing a net-work load balancing cluster to ensure higher availability of the client access server.

Desktop virtualization: up-to-date!

COMPAREX and Zimmer & Lange migrated the Citrix XenApp environment from version 4.5 to 5.0, including the Citrix provisioning process, to ‘treat’ the terminal server. Following this migration, the need to optimize the speed was identified. As a result, COMPAREX is now in the process of testing a new hardware structure for the entire Citrix environment, including SAN and blades. The clinic alliance has also implemented a XenDesktop architecture, which can be used for the XenApp server as well as for virtual client systems that are based on XenServer 5.2 or version 5.6. This will reduce the costs for pre-paring and maintaining applications by up to 25 per cent.

Centralized data: the key to success The next goal for the clinic alliance is to establish centralized data provision, and COMPAREX has ensured that measures for this are already in planning or being evaluated. The consolida-tion of the file servers into a 2-node file server cluster and the approximately 30 Microsoft SQL server instances into a 3-node SQL cluster in cooperation with G-TAC are the most importantsteps in this process.
