Auto audit

when ,shard、proxy Can only be assigned to one model , It is preferentially allocated to machines that can meet the requirements of adding table resources with a smaller sorting value

 3、tcapsvr、tcaproxy Calculation process of the number of available units ： ①  Calculate according to memory capacity ：mNum =  Memory capacity / Storage unit size  ②  Calculated based on disk capacity ：dNum =  Disk capacity size /( Storage unit size * Disk memory ratio ) ③  The number of available units is taken as

mNum,dNum,224（tcapsvr、tcaproxy Maximum number of available units ）

The smallest of the three   notes ： Under each cell model , Storage unit size ： Standard region ：1GB; Multi cell ：0.5GB; Low cost area ：0.25GB;

 4、 In cluster maintenance, when the machine configuration on the shelf mode is formal, only the machines in the formal environment can be on the shelf , For testing, the machine can be put on the shelf formally or on the shelf for testing

 5、 The number of available units of the tested models is 512 individual

4： Add success
