DIMM Installation Pattern for Using Online Spare Memory Feature
To enable online spare memory feature, DIMMs in memory controller must be the same capacities
and type. Depending on specification of memory controller, the spare memory is set in unit of rank
memory.
The logical memory capacity of single rank memory differs from that of dual rank memory when
online spare memory is specified.
Single rank memory configuration
(Physical memory capacity * Number of DIMMs) – Physical memory capacity
= Logical memory capacity
Dual rank memory configuration
(Physical memory capacity * Number of DIMMs) – (Physical memory capacity / 2)
= Logical memory capacity
The server supports the following DIMMs
N8102-317 Additional 1-GB memory: Single rank
N8102-318 Additional 2-GB memory: Dual rank
N8102-319 Additional 4-GB memory: Dual rank
