Component Rules
Generation

Nodes in coexistence systems must follow coexistence rules for their generation. Each generation must have certified storage for the platform to which it is attached.
Arrays

All 6750HX, 6750X, 6700H, and 6690 storage arrays must be hybrid with both HDD and SSD storage drives.

Contact GSS for clique configurations for coexistence systems.

Drives of different capacities can be mixed within a tray.

When mixing drives in an array, RAID pairs/sets should be the same capacity drives. If you mix two different capacities in a RAID pair, PUT treats the larger drive like the smaller drive and you lose the extra capacity.

You cannot mix more than two drive capacities in an array.

  • In a 6750HX/6700H system, 6750HX arrays and 6700H arrays must be in separate cliques.
  • In a 6750X/6690 system, 6750X arrays and 6690 arrays must be in separate cliques.
RAID You cannot mix RAID types.
Design
  • Mixed storage design must be matched to data temperature demographics.
  • Some 6700 and 6750 configurations require a minimum clique size of 3+1 on the 6800H for coexistence.
