What is the optimal drive positioning for pools and volume groups?


When creating pools and volume groups, make sure to balance the drive selection between the upper and lower drive slots.

For the EF600 and EF300 controllers, drive slots 0-11 are connected to one PCI bridge, while slots 12-23 are connected to a different PCI bridge. For optimal performance, you should balance the drive selection to include a roughly equal number of drives from the upper and lower slots. This positioning ensures that your volumes do not hit a bandwidth limit sooner than necessary.
