This task will serve as the overall tracking and planning task to replace the systems that have aged out of warranty @ ulsfo.
The systems have been ordered on #procurement tasks T160934 & T160936.
There is not room on the power overhead to cable up the new systems and keep the old ones online. We'll likely need to offline ulsfo for a number of days, if possible.
CP systems replacement:
[] - receive in new systems cp4021-cp4032 from T160934, verify hardware is correct. This step will likely require the systems to be racked in the top of the racks, as offlining ulsfo on 2017-05-03 is non-ideal.
[] - offline ulsfo, decommission existing cp systems
[] - wipe disks on cp4001-cp4020.
[] - unrack systems after wipe, arrange for sale to IT refurbishment. this may result in storage fees with UnitedLayer.
[] - place new cp systems in old cp system spots, reuse all power and data cabling. ALTERNATIVE: Replace the fiber optic runs in the rack with DAC cables.
[] - setup/install new cp4021-cp4032
