Introduction
The ThinkSystem RAID 540/545 PCIe Gen4 12Gb Adapters are an entry-level 12 Gb SAS/SATA family of internal RAID adapters that offer a cost-effective RAID solution for small to medium business customers. These cacheless adapters support RAID levels 0, 1 and 10, and include an extensive list of RAS and management features.
These adapters leverage the MegaRAID iMR entry RAID firmware stack. The 540-8i and 540-16i implement Reserved Memory Region Reporting (RMRR) which uses server memory for the RAID functions and other background operations. The RAID 545-8i does not use RMRR functions for RAID operations, and instead uses on-chip memory (hostless iMR), thereby freeing up server memory for applications.
The ThinkSystem RAID 545-8i PCIe Gen4 12Gb Adapter is shown in the following figure.
