FRS 8198

Today I upgraded the memory capacity on h1nds1 from 48GB to 72GB. This means both nds servers now have the same memory size. Earlier this morning I looked inside h1nds0 to verify its memory card configuration (three 8GB and three 16GB cards).

In conjunction with expanding the memory, h1nds1's daqdrc configuration file was modified to use the additional capacity by changing the buffer size in the 'start main' command from 50 to 100.

h1nds1  has two banks of three DIMM slots (three black, three blue, interleaved). Initially all six slots had 8GB cards. The three black-slot cards were replaced with three 16GB cards.

h1nds1 was restarted twice, once after the memory upgrade, the second with the new daqdrc configuration.
