 AN!Wiki :: Grid quorum

A Grid Quorum system is one where the nodes (n) in the cluster are arranged in an k^2 arrangement. Quorum is determined by having all nodes in one horizontal row plus at least one node from each row below it.

Here is an example of a 25-node cluster in a 5 x 5 grid;

01 02 03 04 05
06 07 08 09 10
11 12 13 14 15
16 17 18 19 20
21 22 23 24 25

An example of this grid having quorum would be votes from;

01 02 03 04 05
06 07 08 09 10
11 12 13 14 15
16 17 18 19 20
21 22 23 24 25
