Introduction

ULTRACAM is operated at the WHT, VLT and NTT. It also spends time at the labs in both Sheffield and the UKATC. ULTRASPEC was operated on the ESO 3.6m and NTT, is now permanently mounted on the 2.4m Thai National Telescope (TNT). We therefore have bits and pieces of the two instruments at up to seven different sites, making logistics a nightmare. This web page is an attempt at improving our documentation and record-keeping in this respect.


Where are ULTRACAM and ULTRASPEC at the moment?


Backups

The following backups of ULTRACAM's various PCs exist. Note that ULTRACAM refers to the data reduction PC. MAGNETAR is Vik's old (ULTRACAM) lap-top.

rsyncs

We have two identical rack PCs, known as UCAM4 and UCAM5 (which replaced the older rack PCs UCAM2 and UCAM3 in March 2010). They contain all of the ULTRACAM and ULTRASPEC system software. The idea is that if one fails whilst observing (which has happened in the past), a user needs simply to replace one with the other and everything should work without any other software/hardware changes.

In practice, of course, we continually make changes to the system software on the rack PC, and hence we need to regularly rsync the two PCs to keep them up to date with each other. The way we used to do this with the old rack PCs was to regularly rsync the PC currently in use onto /data4 in the SCSI disk array. When we decided to synchronise the two PCs, all we then had to do was to connect the other PC to the disk array and rsync it to /data4. This method, as opposed to the alternative of connecting the two PCs together and rsyncing them directly, had the advantage that we always had an up-to-date copy of the latest system on /data4. With the advent of UCAM4 and UCAM5 we kept the same system, but we decommissioned the SCSI disk array and replaced it with a hot-swappable 2TB SATA disk (known as /data1) for archiving data and a hot-swappable 500GB SATA disk for automatic rsyncing every day whilst observing.

In March 2010 we also commissioned a spare IMEDIA PC (known as IMEDIA2) and a spare (Viglen) data reduction PC (known as ULTRACAM2: from now on, I'll refer to the old (aluminium) ULTRACAM data reduction PC as ULTRACAM1). Confusingly, this means there are now three IMEDIA PCs: IMEDIA1-VLT, which is currently stored at the VLT, IMEDIA1-WHT (more commonly referred to as IMEDIA1 on this web page), which is the usual inhabitant of the electronics rack, and IMEDIA2 (the spare, an exact copy of IMEDIA1-WHT).

In 2012-2013, we upgraded ULTRASPEC for use on the 2.4m Thai National Telescope. This involved procuring a completely new rack and data reduction PC (and spares), as we now want to operate ULTRACAM and ULTRASPEC at the same time at different telescopes. The new ULTRASPEC rack PCs are called UCAM6 and UCAM7, and are more or less identical to UCAM4 and UCAM5. The new data reduction PCs are ULTRASPEC1 (aka DRPC3) and ULTRASPEC2 (aka DRPC4).

The table below lists which rack PC, data reduction PC and IMEDIA PC was being used for each ULTRACAM/ULTRASPEC observing run:

Note that the change UCAM2 -> UCAM3 in the middle of the August 2008 run was made to eliminate the SDSU-PCI card as the possible cause of the SDSU crashes we were experiencing. The change UCAM3 -> UCAM2 in June 2009 was due to the PSU failing in UCAM3. UCAM4 and UCAM5 replaced UCAM2 and UCAM3 in March 2010. The change IMEDIA1 -> IMEDIA2 in March 2014 was due to the disk crash we experienced; we had to buy a new motherboard for IMEDIA1, which is now acting as the spare.

The table below records when each PC was last rsynced and lists any changes made to the system which necessitated the rsync. The direction UCAM2 -> UCAM3, for example, means copying files from UCAM2 to UCAM3, so that UCAM3 is made identical to UCAM2.

Hot-swappable disks

We now have hot-swappable bays installed in all of the ULTRACAM PCs. In this section we record details of the various disks in each of the bays.

We also have hot-swappable bays installed in the two HiPERCAM data-reduction PCs:



Data

Below is a record of each ULTRACAM run and where/how the copies of the data from each run are stored. Note that all of the "Media" are currently stored in the ULTRACAM lab at Sheffield . "USB" refers to USB external hard disks. "/ucam" refers to the hard disk storage array located in Vik's office and "SAN" refers to Warwick's storage area network. "ULTRACAM" refers to the data reduction PC and "RACK" refers to the hard disk storage associated with the rack PC.

Info on other USB disks:

  1. PT5M_USB1 contains all the qsi data obtained with pt5m between 2012-09-13 and 2013-06-26 and is now stored in the Sheffield USB-disk archive.
  2. PT5M_USB2 contains all the qsi data obtained with pt5m between 2011-09-06 and 2012-09-10 and is now stored in the Sheffield USB-disk archive.
  3. USB28 (1.5TB, tiny Toshiba) contains all the qsi data obtained with pt5m between 2013-06-26 and 2015-01-14, the date we switched to the Officina Stellare telescope. A backup of all of the python scripts and the log files are also on this disk, taken on 2015-01-14. The disk is now stored in the Sheffield USB-disk archive.
  4. USB3 is in Vik's office and is used for ULTRACAM backups and storing reduced ULTRACAM data.
  5. USB10 died during the October 2007 WHT run - Maxtor replaced it and this is now in the pt5m crates (I think!)
  6. USB11 (750GB) is in the ULTRACAM crates and acting as a spare.
  7. USB15 is lost! It was returned to Sheffield from Warwick in March 2009 and seems to have disappeared.
  8. USB29 (1.5TB, tiny Toshiba) was in the pt5m crate acting as a spare, but I can't find it now! Seems to be lost.
  9. USB33 (1.5TB, tiny Toshiba) also contains some backups - silver_drpc_backup/ contains an rsync of the ULTRACAM1 (silver DRPC) with the following directories: admin, cc, observer, rhickman, root, sl, star, trm, ukatc, ultracam_data, vsd. Note that the ultracam_data/ directory contains old backups from IMEDIA1, UCAM2 and UCAM3, plus another folder (ultracam_data/root) with older backups of ULTRACAM1. This disk is now stored in the Sheffield USB-disk archive.
  10. USB35 is currently connected to the ULTRASPEC DRPC and contains the data from the 2015/16 and 16/17 observing seasons. Bring this disk home to store in the archive!
  11. USB36 is currently connected to the ULTRASPEC DRPC and contains the data from the 2015/16 and 16/17 observing seasons. Re-use for the 2017/18 season.
  12. USB37 (1.0TB, tiny Toshiba) is in the ULTRASPEC crates in Thailand and awaiting use after USB35 and 36 are filled.
  13. USB38 (1.0TB, tiny Toshiba) is in the pt5m crate on La Palma and awaiting connection to ron to use as the main archiving disk.
  14. USB42-45 (2.0TB, tiny Western Digital) are in the ULTRASPEC crates in Thailand for use in a future run there (or for use by MOSCAM).
  15. USB46 (2.0TB, tiny Western Digital) is with Tim (Somsawat) for temporarily storing his MOSCAM calibration data. This will be reused in a future MOSCAM science run.
  16. USB48 is currently with Tom in Warwick. It should be sent to Sheffield so that the May 2017 data on it can be archived, and then reformatted for use in future ULTRACAM+NTT runs (but only when USB49 is safely stored in the lab at Sheffield, and confirmed to hold both the May and June 2017 NTT data).
  17. USB49 is currently connected to the ULTRACAM DRPC in the NTT and being used for the May-June 2017 ULTRACAM+NTT run. It should be returned to the UK by Matthew Green at the end of the June 2017 run and then sent up to Sheffield for archiving onto the hard-disk archive and then storage in the lab.
  18. USB50 (2.0TB, tiny Western Digital) is in the ULTRACAM crates and should be used for the June 2017 ULTRACAM+NTT run.
  19. USB51-54 (2.0TB, tiny Western Digital) are currently with Dave Sahman, who will be putting them in the ULTRACAM crates for use on the NTT in 2017-2020.
