Ultima Accelerator Overview
Diamanti Ultima Accelerator is a turn-key Kubernetes HCI appliance built on I/O offload technology to turbocharge your stateful and stateless workloads through its QoS capabilities to give deterministic performance. It is an easy to manage solution and delivers enterprise grade storage and network services that enable deployment and management of clusters across different data-centers/availability-zones to achieve High-Availability with zero downtime.
Upgrade support from OCP 4.11
Customers can now upgrade their OSE 3.4.0 clusters running OCP 4.11 distribution to OSE 3.5.0 version with OCP 4.12 distribution
Software Control-plane Node
The software control plane node is a software/VM node in the hybrid Ultima Accelerator cluster to meet Etcd HA requirements when deploying in environments with an even number of availability-zones.
ReadWriteMany Volumes Support
RWX (ReadWriteMany) volumes—volumes that can be mounted in a Read/Write fashion into a number of pods simultaneously—are now supported. RWX volumes are particularly 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.
Fire-drill is now supported as part of Diamanti Accelerator’s disaster recovery (DR) capabilities. A fire-drill is a zero-downtime DR test that mimics the failover behavior of stateful applications across different sites. With a single-click in Diamanti Spektra, a user can create a new instance of the application on another Kubernetes cluster and verify the state of the data on the DR site. During the fire-drill, the original application remains untouched and continues to function with no downtime.
Route metric for multi-endpoint PODs
Diamanti Accelerator now supports per-subnet, default-route-metric configuration when using multiple-endpoints for an application. This is especially useful for ingress controllers where external traffic could be ingressing on one endpoint while getting routed into the cluster on another endpoint. Users now have control over which interface inside a pod gets used for the default route.
Diamanti’s network, storage and management features now work seamlessly with KubeVirt, providing a common, shared environment where developers deploy applications residing in both application containers as well as VMs. VM failovers are also handled seamlessly.
16TB Drive Support
Per node total raw storage available to applications has been doubled to 64TB with this release, enabling support for 16TB NVMe drives.
Online Volume Resize
Users can now expand the PVC size of their volumes while read-write operations are ongoing and without any application downtime.
CRI-o Container Runtime
CRI-o, which is an OCI-compliant container runtime, is now the default container runtime. Docker-built images will continue to run as before.
OCP-4.12 (K8s 1.25)
This release adds support for OCP 4.12 release, which comes with Kubernetes 1.25. Please refer to its release notes for additional information.
RHEL 8.6 and Rocky 8.6
Rocky 8.6 is the default OS distribution with this release. Customers looking for RHEL distribution have the choice of opting for RHEL 8.6 as well.
