<div class="PlainText">Hi Nathan,<br>
<br>
Since we are in the middle of testing the tuple/DST makers, I don't know the file size of tuple/DST. Bradley might know. The recon file size is 400 MB per file and we need 10,000 recon files to be equivalent to the 2015 data statistics. So the total disk space
requirement is 4 TB.<br>
<br>
The tuple maker can generate three tuples, FEE, Moller and trident. Since tritrig-wab-beam is processed by pair1 trigger, I would think there are not many FEE, Moller in the tritrig-wab-beam recon files. If we want FEE and Moller samples, a separate readout/recon
step must be run on wab-beam.slicio. Do we need FEE and Moller? If we don't need FEE, Moller, I will delete the wab-beam.slcio files as each wab-beam.slcio is 450 MB and we need 100,000 files, 45 TB.<br>

What’s the estimate on disk space requirements for the different bits in #1? <br>

> High statistics tritrig-wab-beam production is in progress. About 15% of 2015 data equivalent statistics has been generated, but the production is paused due to lack of disk space. As soon as a disk space becomes available, the production will resume. There
are a couple of issues. 1) What files do we need to transfer to JLab? Only recon files, or only Tuple files, or DST as well? 2) We need a contact person at JLab who finds the disk space and does the transfer. 3) Since the intermediate wab-beam.slcio is large,
requiring 5 TB for 10,000 files (~100,000 files to be 2015 data equivalent), we need to delete these files once the recon files are made. But wab-beam could be useful to generate, for example, wab-beam-tri. How long do we need to keep wab-beam? I would delete
the files once the recons, tuples, and DSTs are made.<br>
