Here is a summary of Points of View and Space requests
General Comments:
- We should consider this to be a request in addition to our existing institutional disks, which are mainly devoted for user analysis and not planned specifically for the HFT calibration.
- (Xin)I think for us, the big request will come from the simulation production and tracking test. My verbal comment on Friday about >10TB is a rough estimate to have sufficient buffering space for this test. I believe the total space we really need may be larger than that (which is hard to estimate now). 10TB should be a good start. And we may approach with the S&C team as some of the tracking test is not particularly only related to us, it should be a global interest.
Subsystem Calibrations:
The PXL calibration shouldn't need too much space, we may need to finish some missing runs, but that in principle can be made as a subsystem request to the production team.
SSD calibration may need some amount of space. Jonathan/team may have a better estimate.
IST needs ~4TB disk space for calibration and performance studies. At the moment, Yaping is using 1.5 TB disk space for IST performance study, alignment and code development, while Babak 1.1TB for IST calibration. They are using their own data01+data02 disk spaces plus temporary data05, as UIC does not have institutional disk space (even if we do, this kind of IST work should be on dedicated disk space, not institutional one). So when I add these numbers up with 1TB of contingency, I get 4TB.
Request: It looks like a request of ~15 Tb if we consider the IST/SSD calibration needs and the big chunk of ~10 Tb for simu and data sample analyses.
P.S. the numbers others are requesting
MTD: 25TB
BEMC: 2TB
FGT: 1TB
EEMC: 1TB
