Research on Server Performance Stability Assurance Mechanisms during Cross-Generation Computing Platform Upgrades

Different generations of servers in US manufacturing data centers has become the norm.However, there are significant differences in BIOS/UEFI, BMC firmware, management interfaces and hardware abstraction layers between different generations of platforms.This leads to problems such as firmware upgrade failure, out-of-band management failure and longer recovery time, which further amplifies downtime costs and compliance risks .Based on a sample of 2,480 servers in real production data centers in three US locations (US-East/US-Central/US-West) in 2024, we propose a BIOS-BMC compatibility optimization method for cross-generation mixed-deployment racks.The empirical results show that compared to the traditional one by one upgrade method, the success rate of firmware upgrade has been improved from 96.6% to 99.2%, the average recovery time has been reduced from 18.4 minutes to 6.3 minutes, the availability of remote KVM has increased by 0.19 percentage points, the error of sensor consistency has decreased by 57.9%, and the auditable compliance coverage has increased by 22 percentage points.This research offers a reusable engineering framework and quantifiable foundation for firmware management and automated upkeep of multi-generation servers in US production settings.
