Kubernetes Persistent Volumes: Ultra-scalable

Simplyblock’s Kubernetes storage solution is tailored for Kubernetes users hosting stateful or I/O-sensitive workloads, such as databases.

Simplyblock combines the baseline performance of best-in-class SAN systems or local NVMe disk with the flexibility and scalability of software-defined storage solutions. Simplyblock is the ideal choice for Kubernetes and virtual machine deployments, such as Amazon EKS and Amazon EC2.

Why simplyblock as Kubernetes StorageClass?

Kubernetes-Optimized Storage

  • Persistent Storage for Kubernetes: Simplyblock provides robust and scalable persistent storage for Kubernetes, ensuring your stateful applications have reliable and high-performance storage.
  • Kubernetes Volumes and Storage Classes: Our solution supports dynamic provisioning of Kubernetes volumes and storage classes, simplifying storage management within your Kubernetes clusters.

Intelligent Storage Features

  • CSI Driver for Kubernetes: Our solution includes a Kubernetes CSI (Container Storage Interface) driver, allowing for seamless integration and management of storage resources within your Kubernetes environment.
  • Multi-Tenancy Support: A single Simplyblock storage cluster can serve multiple Kubernetes clusters, making it ideal for multi-tenant setups.
  • Distributed File System: Write concurrently on multiple containers and nodes with distributed file system of your choice, ensuring high availability and data consistency.

Seamless AWS Integration

  • Amazon EKS Compatibility: Simplyblock is fully compatible with managed Kubernetes, such as Amazon Elastic Kubernetes Service (EKS), enabling easy deployment and management of storage within your AWS infrastructure.
  • EC2 Integration: Leverage the power of Amazon EC2 instances and local NVMe disk to run simplyblock’s high-performance storage solution, ensuring your Kubernetes workloads have the storage performance they need.

On-Premise Compatible

  • Kubernetes-native: Simplyblock is fully compatible with all on-premise distributions of Kubernetes, bringing the easy deployment of NVMe over Fabrics storage to private Kubernetes environments.
  • No external drivers required: NVMe over TCP is natively integrated into the Linux kernel NVMe stack and available for Windows via the StarWind NVMe Initiator or natively in Windows Server 2025.

​Flexible Deployment Models

  • Single Container: Deploy Simplyblock easily as a single container, making it simple to integrate with your existing Kubernetes setup.
  • HCI and Disaggregated Deployment: Simplyblock supports both Hyper-Converged Infrastructure (HCI) and Disaggregated Deployment models, providing flexibility to meet your specific architecture needs.​

Performance of local NVMe disk at scale

Simplyblock uses NVMe over TCP for minimal access latency, high IOPS/GB, and efficient CPU core utilization, surpassing local NVMe disks and Amazon EBS in cost/performance ratio at scale. Ideal for high-performance Kubernetes environments, simplyblock combines the benefits of local-like latency with the scalability and flexibility necessary for dynamic Kubernetes deployments, ensuring optimal performance for I/O-sensitive workloads like databases.

ebs vs ssd vs simplyblock

Scalable

Start from a single node, grow to 255 nodes in a single storage cluster. Scales safely and impactless while online. Performance scales linearly.

Flexible

Capacity and load distribution is re-balanced over time and during changes to the cluster (device failures, repair, replacements, expansion).

Top Performance

Up to 10x lower system cost per TB and up to 50x lower system cost per IOPS while delivering baseline performance as best-in-class SAN systems in top configurations

Deep Integration

Simplyblock offers full, native integration for Kubernetes via CSI. Deploy complete cluster and attach storage to hosts as docker swarm or Kubernetes pod within minutes.

Accelerate your Kubernetes Performance while Saving Costs with Simplyblock

Benefit from the first highly secure and scalable K8s storage solution designed from scratch for hybrid clouds
