On the Feeds page of the Swarm UI, S3 Backup feed can be added, which targets an existing S3 bucket. See S3 Backup Feeds.
The S3 feed behaves like a Replication feed, and it populates the same real-time dashboard charts and feed reports for monitoring backups. (UIS-1027)
SwarmFS Tuning — For SwarmFS exports, several new Advanced settings are available to adjust SwarmFS for the environment:
Read buffer size (ReadaheadSize) allows matching the expected workload on a specific share, lowering for small and non-sequential reads, increasing for large and sequential ones. (UIS-1007)
Parallel read buffer requests (ReadaheadCount) allows tuning the performance of large object reads; the default of 4 reflects the optimal number of threads, per performance testing. (UIS-1007)
Maximum part size (MaxPartSize) allows increasing the part size for large (multipart) uploads to improve the throughput when applications are writing huge files. (UIS-1018)
Collector sleep time (CollectorSleepTime) allows minimizing object consolidation by sending fewer and larger sets of data to Swarm (at the expense of both RAM and read performance) if an implementation is sensitive to how quickly the Swarm health processor consolidates objects, which cannot be guaranteed. (UIS-1018)
Elasticsearch buffer refresh time (ESBufferRefreshTime) allows tuning how rapidly non-SwarmFS object updates are reflected in SwarmFS listings. Lower to reduce the wait for consistency, at the cost of increased load on Elasticsearch. (UIS-1037)
In addition, these issues have been are fixed:
Issues existed with feeds defined to use a non-default admin password. (UIS-759)
Clicking Add Export on the NFS page caused an immediate 500 error if a cluster had no search feed defined. (UIS-441)

This release features improvements to the handling of Swarm Storage settings and how they are accessed in the UI.
Swarm settings include both cluster-wide and node-specific options, which can vary from chassis to chassis. On the Cluster Settings page, the Swarm UI now prevents erroneous changes by hiding the node-specific settings when Platform Server is not implemented and handling those nodes. (UIS-1000)
The Cluster Settings page now includes an option to Show advanced settings. This option reveals all advanced (unpublished) settings that are dynamic (persisted) when enabled. They can be updated on a running cluster without a reboot. As before, bold fonts and Default information displays alert to settings with custom values in the cluster. (UIS-998)

Improved: Swarm settings include both cluster-wide and node-specific options. On the Cluster Settings page, the Swarm UI now prevents erroneous changes by hiding the node-specific settings when Platform Server is not implemented and handling those nodes. (UIS-798)
Improved: Turn off the identify function before removing the disk from the chassis. Failure to perform this so can result in the need to restart the chassis when access tokens expire or are deleted during an active session. (UIS-975)
Fixed: The UI refreshes and reselects them all if deselecting nodes from the queue without Restarting when editing the Rolling Restart Queue. (UIS-957)
Fixed: On the Details tab of the Chassis Details page, the Actions menu for each disk erroneously but harmlessly showed a testing-only command to Fail the disk. (UIS-955)

Aligning with the new architecture of Swarm Storage 10, Storage UI 2.0 has been is extensively expanded to support the monitoring and administration of Swarm implementations, replicating the rich functionality of the legacy Admin Console (which is deprecated) and adding visibility in to Swarm's management API.
