Reduced Acquisition and Operating Expenses Equally important, lower storage costs can be achieved by implementing a software-based RAID solution for internal storage. Hardware RAID card costs can be eliminated along with their associated power and cooling costs; support and management costs can be reduced through the deployment of a common RAID stack across multiple core logic chip sets and motherboards. RAID Performance With today's multi-core processors, RAIDCore runs with little load on the system and achieves comparable and in some case superior read/write performance compared to hardware RAID adapter cards. Since the RAID function is performed by the host CPU there are fewer components to flow through. Given that the server CPU processor and internal memory bandwidth typically exceeds that of a hardware RAID adapter, RAIDCore IO performance can exceed that of a plug-in HBA. RAIDCore TM spec RAIDCore T M I/O Reliability RAIDCore's touched region logging (TRL) feature ensures mirror and parity consistency in the event of system failure for in-progress writes. For RAID 5 what is commonly know as the RAID 5 write-hole vulnerability is eliminated. Boot Protection With an Option ROM integrated with the system BIOS, the boot image can be RAID protected prior to loading the operating system mitigating corruption should a disk failure occur during the boot process. Universal Management RAIDCore runs on the latest chipsets from industry leaders AMD and Intel, as well as SATA/SAS controllers from LSI. This enables system builders and OEMs to offer a broad range of architectures and platforms to their customers, while only having to support RAIDCore. Similarly, customers using the supported motherboards can now combine all of those ports, eliminating the need for external HBAs. No semiconductor supplier offers this level of flexibility.
