Cloud File System Information

The cloud file system provides cloud storage for snapshot replication that enables disaster and ransomware recovery on a recovery SDDC.

Summary

When you select a cloud file system, you can see the following information from the Summary tab:


Cloud File System Information	Description
Details	Shows the name of the cloud file system and the availability zone where you deployed it.
Capacity	Protected capacity. The billable amount of storage capacity used by protected VMs and their snapshots.
Protected sites	Lists the number of protected sites (on-premises or VMware Cloud on AWS SDDC) replicating snapshots to this cloud file system.
Protection	The Protection panel shows the following information: Protected VMs. The total number of VMs being protected by snapshots. Also displays the percentage of protected VMs out of the total number of VMs in vCenter Server. Snapshots. The total number of protection group snapshots and VM snapshots taken.
Recovery	The Recovery panel shows the following information: Recovery SDDC. Displays the recovery SDDCs that are attached to this cloud file system. Live VMs. Current number of VMs running live on the cloud file system.

Capacity Utilization and Storage Space Reclamation

On the cloud file system, capacity usage is computed as part of a background storage space reclamation job that runs every 13 hours. When a large amount of data gets added to or removed from the cloud file system, storage space reclamation can take a long time, so storage capacity might not get updated in 13 hours. You would see old space usage in the UI, and VMware Live Cyber Recovery charges based on space usage information.

For example, if a large amount of data gets written to the cloud file system, space reclamation might run longer and you won't be charged for this new data until the space reclamation job is completed.

Protection Groups

The Protection groups tab for a cloud file system shows all protection groups that are replicating VM snapshots to the selected cloud file system. The list displays protection groups by name and shows their status, schedule, frequency, and other useful information.

The cloud file system protection groups tab shows all groups that are replicating to this cloud file system.

Performance

You can view the following performance information about a cloud file system and any VMs running live on it:


Live VM performance	Description
IOPS	Input/Output Operations Per Second (IOPS) measures the number of read and write commands a storage device or medium completes every second for all workloads on the cloud file system datastore. IOPS also indicates the average KiB size for each read or write operation, measured in Kibibytes (KiB).
Throughput	The data transfer rate to and from the cloud file system datastore, measured in kibibytes (KiB) or Mebibytes (Mibs). Measures the total amount of data that moves along the network path.
Latency	The time it takes for an IOPS request to complete, measured in milliseconds (ms).
Cache hit rate	A measurement of how many content requests the cloud file system NVMe cache can fulfill successfully, compared to how many requests it receives. A cache hit ratio of 90% and higher means that most of the requests are satisfied by the cache. A value under 80% indicates a working set that is substantially larger than supported by the cache.
Replication throughput	The current data transfer rate of all currently running snapshot tasks replicating to the cloud file system datastore, measured in kibibytes (KiB). Measures the total amount of data that moves along the network path.
