EX300 Upgrade Paths
Describes the EX300 ECS appliance upgrade paths.
If there are five or more nodes in the system (VDC) with the same disk size or total node disk capacity, the minimum node
expansion is only one. This upgrade is possible when the expansion node has the same disk size or the total disk capacity of the
existing nodes.
For example, you have an EX300 appliance with five nodes containing 1 TB disks or have a total disk capacity of 12 TB. You can
add a single node with 1 TB disks or a total disk capacity of 12TB.
If you are adding nodes that have different disk sizes than the nodes currently in the system, you must add a minimum of five
nodes at a time.
For example, you have an EX300 appliance with five nodes containing 1 TB drives. If you want to add nodes of different drive
size (2 TB, 4 TB, 8 TB, or 16 TB), you must add five or more nodes, at a time.
NOTE: All drives within a node must be of the same drive size, but there can be nodes of differing drive sizes within a rack.
There are no drive upgrades.
