Can anyone comments on SVR ?
SVR is nothing but a DC-DC PCB.
These SVR's will be installed in the HDU boxes and also includes the HDD status LED's. (If my memory is correct the number of SVR PCB's is 9 per HDU box and 1 will be spare). This will be always on and give power to 8 HDD's. If more than two SVR fail, SVR cannot give power for more than 8 HDD's. If two failed SVR covers more than 8 HDD's, then all HDD's stop working. for example if the 2 failed SVR cover 16 HDDs then all 16 HDD's will stop working.
Also if the 2 failed SVR covers 7 HDDs, then the spare SVR will give power to these 7 HDDs.
Hope its clear.
Thanks very much Kamalarajan. it is clear
