Progress' Cold Spare Replacement option provides Customers with an onsite unlicensed hardware appliance to provide additional resilience in the event of a critical hardware failure on their production deployment. The Cold Spare unit is co-located on the Customer’s premises and in the event of a failure, Progress Support will assist with license transition from the failed production unit. In this scenario, the failed unit is then shipped back to Progress. Progress will then provide a replacement Cold Spare unit for the Customer’s premises. A minimum of two licensed LoadMaster, ECS Connection Manager, or Connection Manager for ObjectScale instances of the same corresponding model (configured in a High Availability (HA) pair), covered by Enterprise Plus (or ECS) Support is required to purchase Cold Spare units. Cold Spare units may be provided from refurbished stock at Progress' discretion.
