Compression

Denotes if compression is enabled (Nutanix AHV & VMware vSAN only)

Datastore Name

The name of the datastore

Datastore Object Name

The object UUID of the datastore

Datastore Path

Datastore Type

The datastore type (underlying technology)

Free Space

The amount of free space in the datastore in gigabytes

I/O Latency

Storage I/O Control size-normalized I/O latency

IOPS

Storage I/O Control aggregated IOPS

Local Datastore

Denotes whether the datastore is a local datastore

Maintenance Mode

Whether the datastore is currently in maintenance mode

Max Queue Depth

Storage I/O Control datastore maximum queue depth

Read IOPS

Average number of read commands issued per second to the datastore during the collection interval

Read Latency

The average time a read from the datastore takes

Read Rate

Rate of reading data from the datastore

SDRS Read IOPS

Storage DRS datastore read I/O rate

SDRS Read Latency

Storage DRS datastore normalized read latency

SDRS Write IOPS

Storage DRS datastore write I/O rate

SDRS Write Latency

Storage DRS datastore normalized write latency

SIOC Active Time

Percentage of time Storage I/O Control actively controlled datastore latency

Storage I/O Control Enabled

If Storage I/O Control is enabled

Storage Stats Collection

Are storage statistics being collected

Stress Level

Stress Level is a flexible load measure which you can customize using the "Stress Settings" pane

vSAN Build Recommendation

This check detects any configuration issues in the vSAN build recommendation engine

vSAN Cluster Health

This check verifies that all ESXi hosts have the vSAN Health Service VIB installed

vSAN Congestions

Congestions of IOs generated by all vSAN clients in the cluster

vSAN Data Health

This check provides a cluster wide overview by summarizing all objects in the cluster and categorizes object health to help you assess not only if an object is healthy or unhealthy, but what it means to the user, whether he should take action, whether he is at risk, and so on

vSAN Disk Configuration

vSAN disk configuration (Hybrid or All Flash)

vSAN Free Capacity

vSAN space available for new allocations.For parent folder, the value displayed belongs to the vSAN cluster with minimum free space

vSAN Hardware Compatibility Health

This check verifies whether the storage I/O controller firmware is compatible with the controller on the ESXi host and the version of ESXi

vSAN Health

Summary of all vSAN health checks

vSAN Limits Health

This check looks at free disk capacity and ensures that the components per host limit has not been exceeded, and that there is some flash read cache capacity remaining

vSAN Network Health

This check tests that all ESXi hosts in a vSAN cluster have been configured so that all vSAN VMkernel NICs are on the same IP subnet

vSAN Online Health

The CEIP check verifies whether the program is enabled for your vCenter Server

vSAN Outstanding IO

Outstanding IO from all vSAN clients in the cluster

vSAN Performance Service Health

This check verifies that the vSAN performance service statistics collection is working correctly

vSAN Physical Disk Health

This check tests whether there is an issue in retrieving the physical disk information from hosts in the vSAN cluster. If this health status is not green (OK), physical disk information cannot be retrieved from the ESXi host

vSAN Total System Overhead

vSAN capacity consumed by vSAN for system needs

vSAN Total Used - Physically Written

vSAN capacity storing actual data of the objects on the vSAN datastore

vSAN Total Used - VM Overreserved

vSAN space wasted due to higher than needed space reservation setting

vSAN Total Used Capacity

vSAN space not available for new allocations

Write IOPS

Average number of write commands issued per second to the datastore during the collection interval

Write Latency

The average time a write to the datastore takes

Write Rate

Rate of writing data to the datastore
