Telescope Upgrades - 2008

A major computer and network upgrade was performed in the summer of 2008. Important highlights include:

  • A 1 gigabit fiber isolated network with a 10 gigabit backbone for the entire observatory. Harvey and Johnson worked diligently on porting current control software over to the new Hewlett Packard (HP) computers. This is the first gigabit network to be installed on Mt. Graham.
  • A cooling system for the HP computer racks was also designed and integrated for maintaining proper operating temperatures of the new computers and networking equipment.
  • Harvey also upgraded the NTP server as well as converted all analog video links from the telescope to fiber optics. This method of isolation was completed to minimize lightning damage, increase network robustness, and protect the new computer equipment kindly donated by Hewlett Packard Corporation.
  • Harvey and Johnson, with Boyle, have been instrumental in continued observer training and support during the observing season.
  • Currently, the VATT computer up-time has been running at 99.8%. With the upgrade, it is anticipated that our computer up-time will increase to 100% reliability.
