AN1600 F1 Network Storage System Quick Specification
Mirroring or Lockstep mode:
Mirroring mode & Lockstep mode need the channel 1 & channel 2 with identical DIMMs. 1A and 2A should
be the same type, size and manufacturer. 1B and 2B memory should be the same type, size and
manufacturer.
Channel 3 is no function in this mode.
Same rule is applied to the CPU2 memory channel 1, 2, 3.
For mirroring mode, the memory contains a primary image and a copy of the primary image. Therefore, the
effective size of memory is reduced by at least one-half.

Sparing mode
In this mode, if the system detects degrading memory and did not crash, the data in the failed channel will be
copied to the spare channel. The failed channel is then isolated and the spare channel becomes active.
However, any uncorrectable error that happens before the isolation will still cause the system to stop normal
operation.
Channel 3 is the spare channel. Therefore, the effective size will be reduced by one-third.
Follow the population rules described in the independent mode.
Sparing mode requires that all three channels use identical DIMMs. 1A, 2A and 3A should be the same type,
size and manufacturer, likewise for 1B, 2B and 3B. The same rule applies to processor 2.
