BIRN Cyberinfrastructure — System Availability
Rack Availability
- Racks are scheduled to be available 7 x 24
- Each month we will compute the total available hours (Total Hours)
- We will deduct from the total hours available any scheduled down time for maintenance, backups, upgrades, etc. (Scheduled Down Time)
- Available Hours = Total Hours – Scheduled Down Time
- Any other outage is unplanned and we deduct this from the remaining available hours (Unplanned Outages)
- Percent Available = (Available Hours – Unplanned Outages)/Available Hours * 100
