What's New

Overlay Network

Ultima Enterprise now supports an Overlay Network (Private Network) feature. This simplifies network administration by providing a cluster-wide, single, private IP address pool from which IP addresses can be assigned per pod. Using this feature, pod-to-pod traffic within a node is forwarded using a private IP address, while pod-to-pod traffic across nodes is forwarded using VxLAN overlay networking. IP address access can be controlled on namespace basis.

Container Storage Interface

The Container Storage Interface (CSI) now provides a way to use compliant block and file storage systems with containerized workloads.

Persistent Volume Provisioning/Resizing

Cluster administrators can now provision both dynamic and static persistent volumes in a cluster and also resize persistent volumes.

Storage Mirroring

Continuous availability is now enhanced through support of three-way synchronous mirroring. Logical disk volumes can now be replicated on separate physical hard disks with each mirror on a single node. The scheduler auto selects and spreads the mirrors on different nodes in the cluster. (You can also choose to disable the auto-selection feature.)

Snapshot Enhancement for Volume Restoration and Data Protection

A volume can now be restored to a point-in-time copy of data using the snapshot feature. Ultima Enterprise supports up to 16 snapshots per volume. To ensure data protection, snapshots created on a cluster cannot be exposed directly to an application. Instead, a Linked Clone Volume (LCV) is created from a snapshot, which is then used by the application.

Backing up Persistent Volume Claims (PVCs)

You can now configure the Backup Controller (which allows back up of application data to a Network File System server) to create a backup of a specific Persistent Volume Claim (PVC), either all PVCs within a specific namespace or all PVCs in the cluster. The persistent volumes associated with the PVCs are then backed up to the specified NFS target.

User Management

You can now on-board a user or group of users to a cluster, authenticating the users and authorizing them to access cluster resources.

RWO/RWX Support for Volumes

The ReadWriteOnce (RWO) access mode can now be used to restrict volume access to a single node. This enables multiple pods on the same node to read from and write to the same volume. This is useful for web and app servers that serve the same files (i.e., shared database) as well as continuous integration (CI) systems, such as Jenkins, which can use a shared volume for artifact storage rather than unnecessarily duplicating data and impacting CI performance.

Run VMs on Kubernetes

Ultima Enterprise enables support for running VMs on the Kubernetes clusters. With this feature, customers can spin up VMs or lift-and-shift their existing VMs running non-containerized workloads to the Ultima Enterprise Kubernetes cluster and run them parallel to their containerized applications. Note that this feature is currently supported only on GCP clusters.


Centralized Multi-Cluster Management

Ultima Enterprise delivers everything you need to run all your Kubernetes clusters with a common workflow on the most appropriate infrastructure (VMs, bare-metal, on-premises or cloud).

Kubernetes Optimized Storage

Ultima’s Kubernetes-optimized storage, enhanced by Diamanti’s patented block storage architecture, provides containerized applications with access to data in easily consumable, persistent volumes, boosting performance and ensuring that data remains available during any life-cycle activity (i.e., upgrades, patches, cluster deactivation) a prerequisite for stateful applications).

On-Demand Capacity Management

Storage capacity can be instantly allocated in response to demand (e.g., unexpected business surges) and/or to make intelligent use of the most cost-effective environment, such as shifting I/O intensive applications from the cloud back on-premises.

Application Migration

Seamlessly locate and relocate applications as needed across cloud and on-premises environments for deployment, expansion, migration and failover.

Integrated Networking

The management of networking ports, overlays and bandwidth in Kubernetes can lead to interoperability challenges, making it difficult to monitor and secure network traffic. Diamanti streamlines configuration through its unique plug-and-play Container Networking Interface that integrates directly with any network infrastructure.


Rely on Ultima’s built-in L2/L3 10Gbps Ethernet to ensure that as traffic crisscrosses your Kubernetes implementation, you get the bandwidth you need to ensure performance.

VIP-Based Cluster Management

In Kubernetes, instead of an actual IP address connected to a network interface, different services are associated with virtual IP (VIP) addresses that forward traffic between pods and remain operational even if an individual pod gets taken down. Integrated VIP management in Ultima Enterprise ensures up-to-date mapping between VIP addresses and pods.

User Management (LDAP/RBAC)

Ultima Enterprise comes with a full set of policy-driven, role-based access control (RBAC) tools simplifying the process for managing user access. Administrators can control access via roles that function per project or cluster-wide and get the visibility they need for compliance with Center for Internet Security (CIS) best practices, while also minimizing the resources devoted to access control. Integration with both lightweight directory access protocol (LDAP) and active directory (AD) enable user authentication and streamlined user access to resources.

Air-Gapped Clusters

Increasingly, companies are seeking to take advantage of Kubernetes to run highly-secure, mission-critical workloads on isolated, air gapped environments. Diamanti Ultima provides the infrastructure and dependency planning to make air gapping successful.

Zero Disruption Failover & High Availability

Through the multi-zone clustering capability, a Kubernetes environment can be set up with multiple, geographically-distributed availability zones (failure domains). If an unexpected outage occurs, the Diamanti control plane can fail over instantaneously from one location to another with zero disruption. Kubernetes applications can also seamlessly access storage volumes across availability zones, enabling high availability of application data.

Data Security

Ultima offers protection for data-at-rest with AES 256-bit volume encryption as well as through hardware-based, self-encrypting drives. With these capabilities, enterprise customers can prevent data theft and protect against security breaches without incurring significant performance penalties.


Simplify Kubernetes deployment through work templates (i.e., application specifications). Build once, deploy many.

Management Platform

Rely on the Ultima Enterprise management console—a single-pane-of-glass for managing all your Kubernetes clusters across all your cloud and on-premises environments. Dashboards deliver visibility into applications and infrastructure performance including compute and memory consumption, network utilization, storage performance/capacity and much more. Querying and analysis capabilities allow you to drill down at any level—cluster, tenant, project, node, pod, container—and get the data you need to keep fine-tuning performance.
