Read Flash Cache	Indicates whether Read Flash Cache is used in the Storage Pool
Capacity alert thresholds	The alert thresholds, as percentages, configured for capacity usage. Thresholds may be configured for the entire system, or per Storage Pool.


SDS Summary
Total	The total number of SDS nodes
`n` SDS nodes have membership state 'Joined'	The number of SDS nodes that are connected to the cluster, can receive I/O, and hold primary and secondary copies of data. It takes some time from actual disconnection until the SDS is disconnected from the cluster, or the reverse. There are also up-pending and down-pending states.
`n` SDS nodes have connection state 'Connected'	The number of SDS nodes currently connected to the MDM
`x` TB (`y` GB) total capacity	The total amount of available raw storage This does not represent the total capacity available for volume allocation.
`x` TB (`y` GB) unused capacity	The quantity of raw capacity in the system that can be earmarked for specific purposes, such as Spare, or used for new volume creation
`x` Bytes snapshots capacity	The quantity of capacity used for storing snapshots
`x` TB (`y` GB) in-use capacity	The total quantity of healthy, degraded, and failed capacity
`x` Bytes thin capacity	The quantity of capacity currently needed for storage purposes
`x` TB (`y` GB) protected capacity	The quantity of capacity that is fully protected (primary and secondary copies of the data exist)
`x` Bytes failed capacity	The quantity of capacity that is not available at all (neither primary, nor secondary copies)
`x` Bytes degraded-failed capacity	The quantity of degraded-failed capacity. When an SDS fails, all of its capacity is defined as degraded-failed, and the secondary copies (which are spread across the Protection Domain) are defined as degraded-healthy.
`x` Bytes degraded-healthy capacity	The quantity of degraded-healthy capacity. When an SDS fails, all of its capacity is defined as degraded-failed, and the secondary copies (which are spread across the Protection Domain) are defined as degraded-healthy.
`x` Bytes unreachable-unused capacity	The quantity of capacity not configured for any use type in the system that is currently unavailable
