WebAug 27, 2016 · Standard Deviation of Count Rates. The standard deviation of a count rate is. where σ is the standard deviation of the total count n of a radioactive sample obtained in time t. Because n is equal to the count rate c times the counting time t, (4.3) Problem 4.2. A radioactive sample is counted for 12 min and gives 8640 counts. WebKeep in mind that the PGs per OSD (and per pool) calculations take into account the replica count ( pool size= parameter ). So, for example.. if you're using a default of 3 replicas.. 16 * 3 = 48 PGs which allows for at least one PG per OSD on that pool. Even with a size=2, 32 PGs total still gives very close to 1 PG per OSD.
