During the next two nights, we will change the chassis of current private sql and switch to a configuration which is:
. more efficient
. less sensitive to heat
This configuration is being tested for several months and the results are conclusive.
The migration will take place at night, and no data loss will occur. During this time, operations via manager/soap will be stopped.
For a few minutes, private sql will be in a "read only" mode, then it will be unavailable during the chassis change.
