Swarm combines the scalable software-defined object storage of Swarm Storage with the components to support diverse implementations:

Swarm Cluster Installer - Browser-based installation utility for vCenter environment
Swarm Cluster Services - Cluster for configuration and storage node deployment
Storage Cluster - Cluster for Swarm storage nodes
Elasticsearch - Cluster for search and historical metrics, with DataCore-specific customization via an RPM
Content Gateway - Gateway for cloud-based client access (S3)
Storage UI - Website for storage cluster management
Content UI - Website for cloud content management
SwarmFS - Optional connector for NFS clients

Swarm 15.3.1 - Updated October 2023

Storage	SCS	SCI	ES, Search	Gateway	Content UI	Storage UI	SwarmFS
15.3.1	1.6	2.6	7.17.9, 7.1.0	7.10.7	7.10	3.5	3.2

Enhanced Static IP Support: Support for static IPs is further enhanced, with the ability to set specific addresses manually via SCS.
Removed Volume Limitation: Removed a limitation on the number of volumes that a Swarm storage node could serve.
Safari Support: Support for Safari has been added in the Content UI.

Swarm 15.3 - Updated August 2023

Storage	SCS	SCI	ES, Search	Gateway	Content UI	Storage UI	SwarmFS
15.3	1.5.1	2.6	7.17.9, 7.1.0	7.10.6	7.9.1	3.5	3.2

Improved Stability: Improved CPU utilization in dense cluster storage nodes will reduce spontaneous process restarts and other instabilities.
Elasticsearch Upgrade: Swarm Storage 15.3 requires upgrading Elasticsearch to 7.17.9. The Elasticsearch cluster's rolling upgrade can be done before or after upgrading to Storage 15.3.
Retention Policies: Fixed an issue where updates to retention policies that failed, typically due to network-related issues, could result in the loss of the object.
Support for Static IP Addresses: When used in conjunction with Swarm Storage 15.3, SCS by default supports the use of statically allocated IP addresses.
Improved Support: Improved support for booting large clusters via SCS.
