ThinkServer RD550 10-Core Server
The Lenovo ThinkServer RD550 is a rack-mount server system built around a 10-core processor running at 2.3 GHz. It ships with 8 GB of system memory and a 720ix controller with 1 GB of dedicated cache. This configuration targets small-to-mid-size businesses that need reliable compute density in a standard rack footprint.
720ix Controller Cache Limit
The onboard 720ix controller provides 1 GB of cache for RAID operations, which accelerates typical read and write workloads. That cache size sets a practical ceiling on the amount of active data the controller can buffer before flushing to disk. Workloads with very large random-write working sets will see diminishing returns once the active set exceeds the available cache.
8 GB Memory Headroom
Eight gigabytes of installed memory handles light virtualization, file serving and basic database tasks without pressure. Memory-intensive applications or higher consolidation ratios will require additional DIMMs to avoid swapping and maintain consistent response times. The platform supports further expansion, but the shipping configuration is sized for entry-level deployments.
