ThinkServer TD100 and TD100x Types 4203, 4204, 4205, 4206, 6398, 6399, 6419, and 6429: Installation Guide
changes. For more information on the Configuration/Setup Utility program, see
the User Guide. When you use online-spare memory, you must consider the
following information:
- You cannot enable online-spare memory while the server is operating in
mirroring mode.
- The minimum memory configuration is two single-rank DIMMs installed in
branch 0, DIMM connector 1 (in channel 0) and connector 4 (in channel 1);
however, online-sparing is not supported with this configuration.
- To support online-sparing in branch 0, you must add a second pair of
DIMMs. The spare pair of DIMMs can be single-rank or double-rank and
must be the same speed, type, size (or larger), and technology as the
failed pair of DIMMs. The spare pair must be installed in branch 0, DIMM
connector 2 (in channel 0) and connector 5 (in channel 1). However, if the
DIMMs are double-rank and you install the spare pair of DIMMs in branch
1, DIMM connector 7 (channel 2) and connector 10 (channel 3) rather than
branch 0, then branch 1 will support online-sparing and branch 0 will not.
- Branch 0 and branch 1 operate independently.
(normal mode):
– DIMMs must be installed in matched pairs. If you install a second pair of
DIMMs in DIMM connector 7 and DIMM connector 10, they do not have to be
the same size, speed, type, and technology as the DIMMs in DIMM connector
1 and DIMM connector 4. However, the size, speed, type, and technology of
the DIMMs that you install in DIMM connector 7 and DIMM connector 10 must
match each other.
– The following table shows the DIMM upgrade configuration sequence for
operating in non-mirroring mode (normal mode).
