The Jan Yperman Hospital isn’t the biggest hospital in Belgium, but it is highly focused on innovation. They have:
Based on the first meeting we had with the customer; Jan Yperman Hospital, we initially proposed an EX8216 design within the core and within the data centre we opted for the EX4500. After some more extensive talks with the customer we got a better view on the requirements and the fact that there was a need for a network of the future. Topics like EVB, VLXAN, FCoE were also discussed. This was not an easy win as we were up against strong competition for the deployment. Cisco proposed the Nexus 7000/5000 and Nexus 2000 as ToR switches.We were confident in our proposal against our competition and had confidence in QFabric’s features and functionality.
We all know that more and more traffic in the data centre is East – West traffic and that this has an impact on how you need to build the network. But with this particular customer being a hospital there was also a need for high speed connection to the access layer, which added further complexity to the deployment by requiring North – South traffic too.
The example below shows you that the hospital not only needed East – West traffic, but also has a high demand of North – South traffic.
Because of this high demand the Nexus solution wasn’t the best solution for East – West and North – South traffic. The one big disadvantage of the Nexus 2000 solution is the bandwidth you have for East - West and North – South traffic.
We all know that the Nexus 2000 is a network extender, which doesn’t do LOCAL Switching; this means that ALL traffic (even traffic between two ports on the same 2000 switch) needs to be sent up to the parent switch (5000/7000). If you then know that you only have 80 Gbps for ALL this traffic, this then creates a bottleneck.
Another problem with the Nexus deployment is that you have to manage all switches separately and that the configuration is complex compared to the VC (Virtual chassis) concept of Juniper Networks. From this you can see why QFabric was chosen over the Nexus.
Benefits of QFabric
Because all the above mentioned requirements we knew that we had to choose another direction. Jan Yperman Hospital was the perfect match for “The New Network” and we talked and showed them “The network of the Future” …. QFabric.
All these things including high speed, low latency, scalability and not forgetting the future proof design made it very clear to Jan Yperman that this was the correct way to go.
Below shows the design of core and data centre:
And here’s what Francky Deleu, ICT manager, Jan Yperman Hospital said, “Jan Yperman Hospital has a reputation for excellent patient care and research, so we really value innovative technology that can enable new working methods, clinical practices and patient services. QFabric is an ideal solution for our data centre because it delivers radical capabilities, outstanding performance and also provides a future-proof path for scalability and cost control.
Of course, reliability, simplicity and stability are also key concerns for a hospital’s network, all of which QFabric delivers. We were particularly impressed by its low latency.”
Once the full implementation has been completed I’ll be writing a follow up blog, so watch this space!
