5 The HP SmartArray P410i and P411 RAID controllers and HP SAS expander card (HP D2D4312) Overview The HP D2D4312 has three RAID controllers. • The P410i RAID controller is integral to the DL370G6 motherboard and is used to control the 12 hard disk drives internal to the HP D2D4312 via the HP SAS Expander card in slot 1. • The two P411 cards are used to connect the external storage shelves to the D2D 4312 and are located in PCI-e slots 5 and 6. • Each P410i and P411 RAID controller is fitted with 512 MB RAM and one 512 MB FBWC (Flash Backed Write Cache). NOTE: If you replace a motherboard with integral P410i card, or a P411 card, you must add the RAID 6 license for the card, as described in the relevant sections below.
