There are 16 buffered DIMM slots on the p24L for a maximum of 256 GB (16x 16 GB DIMMs).
The memory-placement rules are as follows:
- Install DIMM fillers in unused DIMM slots to ensure proper cooling.
- Install DIMMs in pairs. Both need to be the same size.
- Both DIMMs in a pair must be the same size, speed, type, and technology. You can mix compatible DIMMs from multiple manufacturers.
- Install only supported DIMMs, as described on the IBM ServerProven website:
Storage configuration impact to memory configuration
- If HDDs are chosen, then only very-low-profile (VLP) DIMMs can be used because of internal spacing. There is not enough room for the 2.5-inch drives to be used with low-profile (LP) DIMMs. Verify your memory choice to make sure it is compatible with the local storage configuration.
- The use of SSDs does not have the same limitation, and LP (or VLP) DIMMs can be used with SSDs.
