Figure 11. Example of R910 Intra-Socket Mirroring

Note: A1, A3 are mirrored to A2, A4; B1, B3 are mirrored to B2, B4; C1, C3 are mirrored to C2, C4; D1, D3 are mirrored to D2, D4; E1, E3 are mirrored to E2, E4; F1, F3 are mirrored to F2, F4; G1, G3 are mirrored to G2, G4; H1, H3 are mirrored to H2, H4.

For mirroring, the R810 will support 2P/4P configurations with 32 DIMMs only. When mirroring is enabled, only half of the physical memory will be visible to the system software. A full copy of the memory is maintained, and, in the event of an uncorrectable error, the system will switch over to the mirrored copy. In 2P mode, the mirroring will be inter-node with hemisphere mode enabled.
