Zhihong Yu commented on HBASE-5127:
-----------------------------------
{noformat}
<listitem>One region server with the default heap size (1GB) and the default
block cache size will have 217MB of block cache available.
{noformat}
Using the formula above the item, I get 0.25 X 0.85 = 0.2125 which is 213MB.
