THE GRAUBÜNDEN CANTONAL HOSPITAL were one of the first to opt for a virtual desktop infrastructure based on Citrix technology, with its data centre providing desktops on low-maintenance thin clients—not least because endpoints are deployed in highly sensitive areas such as the operating theatre and intensive care unit. Although easy to manage, the system displayed limitations that are not uncommon in VDIs: Performance would rapidly drop during intensive user access, especially for graphics-heavy workloads. Video conferencing was hardly possible and videos and 3D simulations were sluggish on the end devices, which is a huge issue considering the proliferation of imaging technology and simulations in modern healthcare.

Michele Donnicola, Head of ICT Infrastructure at Graubünden, clarifies the overarching strategy: “Our lean hospital strategy aims to give users a mobile, high-performance, individual workstation. Doctors and caregivers need to be able to document and access information at their patients’ bedside and work as productively from home as they can in the hospital. However, the old VDI infrastructure’s sub-par graphics performance was standing in the way of achieving this aim.”

Desktops straight from the data centre.

In collaboration with Bechtle Switzerland and its partner, HPE, the hospital’s ICT team therefore developed and implemented a new desktop solution from scratch. “The most important requirement to us was graphics performance and a high degree of standardisation in order to cover approx. 80 to 90 percent of the workplaces, with data security, recovery and business continuity not far behind,” says Michele Donnicola. Using this catalogue, the partners considered various technology concepts and ultimately designed a solution that combines the advantages of centralised IT with the performance of dedicated hardware: HPE Moonshot.

Unlike VDI solutions that require a hypervisor layer to virtualise hardware resources, HPE Moonshot provides users with a desktop with a dedicated graphics processing unit (GPU) and its own super-fast SSD flash storage located in the data centre. This way, even graphics-intensive applications can tap into enough computing power. An HPE Moonshot infrastructure consists of an HPE Moonshot chassis that holds modular plug-and-play Moonshot cartridges. Each rack can be loaded with up to 45 cartridges and is pre-installed with all the essential components for management, power supply, cooling and networking. The desktops running on Moonshot in Graubünden are still published and centrally managed via Citrix software. Medical staff and administrators have been working with the new VDI infrastructure for several months. “The decision to go with HPE Moonshot was spot on, as things stand today” sums up Michele Donnicola, explaining why:

THE GRAUBÜNDEN CANTONAL HOSPITAL provides a wide range of medical and surgical services with treatments covering 33 disciplines. With some 2,500 staff, is the largest private healthcare provider in the Swiss canton of Grisons. At three sites in the cantonal capital Chur, around 18,000 inpatients and over 80,000 outpatient cases are treated every year. The modern hospital has two hi-tech data centres that provide all IT services for the nine departments and a 45-strong IT team to take care of the systems and applications.

Despite maximum standardisation, the user experience has improved dramatically and in particular with graphics apps. Our doctors can now view high-resolution x-rays and smooth running 3D animations and hold video conferences from home or on the road via the hosted desktop environment, which has helped enormously during the COVID-19 pandemic. Thanks to the combined efforts of HPE and Bechtle, we received the HPE Moonshot cartridges very quickly and were able to migrate key medical staff very fast. It goes without saying that this technology will help us better meet the challenges posed by the pandemic.

HPE Moonshot’s well-structured system architecture simplifies system management: By doing away with the virtualisation layer and with data now being stored directly on the Moonshot cartridges rather than in an SAN, performance has been given a boost and troubleshooting is much easier, too. Michele Donnicola: “Problems are very easy to track and are limited to the respective cartridge’s 15 users. HPE Moonshot reduces data centre complexity and gives our team the security they need, plus the technology allows resources to be assigned to user groups in a very targeted manner.”

 Another advantage is the system’s scalability. When additional desktop workstations are required, all you have to do is add a cartridge to the rack. Despite dedicated hardware power for users, application software can be managed with a central image as easily as in a traditional VDI infrastructure. The solution is even prepared for worst-case scenarios. By distributing the four Moonshot chassis over two data centres, hospital staff can still access some 80 percent of their standard IT performance, even if one data centre completely blacks out.
