Lenovo Ultima Accelerator With Spektra
#1 Enterprise Hyperconverged Infrastructure For Kubernetes
Ultima Accelerator, Diamanti’s purpose-built Kubernetes HCI appliance delivers best-in-class bare-metal performance for your stateful and stateless workloads. Get Kubernetes up and running in just 15 minutes and achieve as much as 70% cost savings versus competing platforms.
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 and 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.
What's New
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
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.
KubeVirt
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.

- Diamanti Ultima Accelerator is a comprehensive HCI Kubernetes appliance—a complete turnkey solution with a CNCF certified K8s distribution, Diamanti CSI for storage services, Diamanti CNI for networking, security, cluster management and unmatched I/O acceleration for mission critical cloud native applications.
- Automatically discover Ultima Accelerator appliances in your network domain so you can do an easy-click selection of nodes and set up your Kubernetes cluster in less than 15 minutes.
- With high performance direct-attached NVMe storage, the Diamanti CSI auto configures the cluster storage pool for simple provisioning of mirrors for the persistent-volumes needed to ensure HA of your application data.
- With 4x10G network bandwidth for containers, 4xNVMe direct-attached storage per node, and 2x10G dedicated bandwidth for storage mirroring, Ultima Accelerator delivers millions of IOPs in a small footprint.
- Enterprises enjoy not only integrated. high-capacity storage and networking, but its QoS capabilities combined with I/O offload, enables SLA enforcements through configuration of minimum guarantees and maximum limits for storage and networking.
- Diamanti’s unique I/O offload technology implements dedicated, isolated resources addressing the storage and networking for each volume and network endpoint in a container.
- The isolation of resources, combined with granular QoS, completely eliminates the noisy neighbor problems normally seen when running a higher density of applications per node.
- Diamanti Ultima Accelerator supports air-gapped deployments out-of-the-box.
- It comes pre-packaged with all the software and container images removing any dependency on external connectivity to set up clusters.
- Upgrades are downloadable as a single package that seamlessly get installed across all nodes of a cluster.
- Diamanti’s high performant storage data plane comes bundled with enterprise grade Kubernetes storage services to protect data from unplanned failures and ransomware attacks.
- The mirroring feature, combined with Diamanti’s intelligent scheduler, ensure mirrors are placed across availability zones to provide HA on zone failures.
- Additionally, Ultima Accelerator supports space optimized instant Snapshots to protect against data loss and restore volumes to a specific point in time.
- And with its Replication feature, the Ultima data plane replicates data across clusters to provide a Disaster Recovery (DR) solution that spans multi-cloud deployments.
- Diamanti’s networking architecture gives maximum flexibility over IP address management (IPAM) for your applications.
- To have full control and visibility into the pod IP address assignment, a combination of static and dynamic IP-addressing can be used with user configured subnets.
- These IPs are visible in the L2 domain to enforce any firewall/network policies.
- Additionally, Diamanti CNI also supports overlay networking to enforce private IP-addressing for applications using VxLAN based encapsulation.
- Ultima Accelerator 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.
- Integration with both lightweight directory access protocol (LDAP) and active directory (AD) enable user authentication and streamlined user access to resources.
- To achieve maximum security for your data, Ultima Accelerator supports encryption for data at rest as well as data in transit.
- For data at rest, encryption is achieved through Self Encrypting Drives (SED).
- For data in transit, volumes are encrypted at the host layer through user provided encryption keys.
- Encrypting a volume also encrypts its snapshots and clones.
- Ultima Accelerator comes with out-of-box support for Spektra Enterprise, Diamanti’s feature rich multi-cluster management solution. Spektra’s wide range of features—for managing multi-tenancy, replication and DR across hybrid environments, the ability to deploy, manage and migrate applications across clusters—gives the flexibility and scale that developers and administrators look for in multi-cluster, multi-cloud environments.
- While enterprises are rapidly adopting cloud native technologies, there remain a significant number of applications that are yet to be containerized and continue to run in VM environments.
- Diamanti integrates the Open Source KubeVirt technology to Ultima Accelerator to enable the running of VMs on a Kubernetes platformalongside containerized workloads.
- These VMs get the storage and network performance boost from Accelerator’s offload architecture along with its I/O isolation and QoS capabilities.
- Get the enterprise-grade storage services you need to achieve any RPO/RTO recovery requirements including snapshots, asynchronous replication and mirroring (synchronous volume replication) across storage devices or availability zones.
