Frequently Asked Questions

What is the difference between hardware RAID and software RAID?: Hardware RAID uses a dedicated RAID processor on the controller card — offloading RAID computation from the server CPU for consistent performance. Software RAID uses the server CPU, which can impact performance under heavy workloads.
Can I connect more than 8 drives?: Yes — using SAS expanders, the L3-25121-82A can support significantly more drives beyond the 8 direct-connect ports.
Does this controller support SSD caching?: Verify CacheCade support with LSI documentation for this specific model — some MegaRAID controllers support SSD caching via the CacheCade feature.
