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.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"item\"\u003e\n\u003cdiv class=\"break-avoid\"\u003e\n\u003cp\u003eThe ThinkSystem RAID 545-8i PCIe Gen4 12Gb Adapter is shown in the following figure.\u003c\/p\u003e\n\u003cp\u003e\u003ca id=\"figure-thinksystem-raid-545-8i-pcie-gen4-12gb-adapter\"\u003e\u003c\/a\u003e\u003ca data-caption=\"ThinkSystem RAID 540-8i PCIe Gen4 12Gb Adapter\" data-fancybox=\"all\" href=\"https:\/\/lenovopress.lenovo.com\/assets\/images\/LP1552\/RAID%20545-8i%209520-8i.jpg\"\u003e\u003cimg alt=\"ThinkSystem RAID 545-8i PCIe Gen4 12Gb Adapter\" src=\"https:\/\/lenovopress.lenovo.com\/assets\/images\/LP1552\/RAID%20545-8i%209520-8i.jpg\"\u003e\u003c\/a\u003e\u003cbr\u003eFigure 1.
