Minimum Requirements for non-frame-saving camera

h2, Current NRAMM setup

SEMC file storage policy

and policy for file storage:

  1. 10 Gbs network between frame saving camera and the file server.
  2. Raw frames are transferred off camera with rsync using rawtransfer.py which also removed the finished frame stack on the camera to make room for more to come.
  3. These raw frames are needed if default frame processing does not give optimal results. We keep these on network drive for 30 days and make it user's responsibility to archive this on external drives. bzip or bzip2 are commonly used by the users to compress the files. Since the raw frames are integers, it can be easily compressed to 4-10 times smaller.
  1. In the frame processing Appion script, if frame alignment is performed (usually finished within a day or two after data acquisition), the aligned frame stack is removed right away after integrating into single sum image to save space.
  2. User will use the summed aligned-movie saved in the Leginon database as "-a" images. 95% of the users do not require frame-aligned stack after this point.

- 10GB network card to support direct transfer from K2 camera and connection to the scope.
