Hi Matthieu
We are lucky enough to benefit from a new infrastructure that the university recently set up.
This is a central server in the basement of our building (mirrored on the second campus) which is expandable to zetabytes I was told, and can be expanded in increments of 10TB plug and play modules added when needed.
Our microscopes are directly connected to the server via a 1Gb/sec fiber. That is Gbit/sec, not GB which is GByte and is 8 times more. So 10 Gb/sec transfers around 120 MBytes/sec. This will likely be upgraded to 10 Gb/sec switch (which will allow us to transfer over 1.2GB/sec).
The data is acquired locally on the microscope computer. Our users must transfer all their data to the server and empty the local drive before they turn off the system. Any data found on the local drive is immediately deleted.
On top of that, we have a Virtual Desktop Infrastructure (VDI) consisting of 2 powerful Remote Desktop Servers machines (256GB RAM, 2 Graphic cards with 16 GB RAM each) that are maintained by the university and are locate in the server room. These are also expandable/upgradable and we are not in charge of them so we only enjoy using them! :D
These machines as well as the server are accessible remotely via a software called VMWare. This allows us to log in to the VDI from any computer (even a mobile phone). Logging to the VDI creates a virtual Windows desktop on which we have Fiji, Cell Profiler, Imaris, NIS elements, Matlab...
Several users can log to each RDS at the same time. They share the resources.
Having an infrastructure that is maintained centrally has simply changed our (my) microscopy life! :)
Med vänlig hälsning / Best regards
Sylvie

Dear all,
We are producing massive amount of data that legally needs to be stored for up to ten years. This data also needs to be analysed fairly quickly -hence storage on local servers. Furthermore, some software companies (Huygens, Imaris...) are now offering server-based applications for image analysis -all the hard work is done on the server and your computer is just a terminal.
Currently, we tell users to transfer their data to NAS immediately after imaging, so the microscope computers are not clogged. Image files found on these computers are fair game after a month. We expect users to then back up their files from the NAS to cloud. All our image analysis is done on fairly beefy workstations and not server based.
As I'd like to future proof our IT, it would be great to know what servers/storage space do you have as part of your facilities/institutes? What solutions do you have for long term storage vs short to medium terms? Do you have server based applications?
