Performance of Local NVMe, but 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 storage deployments, ensuring optimal performance for I/O-sensitive workloads like databases.

Simplyblock provides low-latency, high performance Kubernetes storage.

Why Simplyblock for Your NVMe-based Kubernetes storage?

At its core, simplyblock implements an NVMe-first architecture that transforms how containerized applications interact with storage. By utilizing NVMe/TCP- the modern successor to iSCSI – simplyblock provides native integration with Linux and Windows kernels, eliminating the need for proprietary drivers while delivering superior performance compared to traditional protocols.

For Kubernetes environments, simplyblock offers comprehensive storage orchestration through its Container Storage Interface (CSI) driver. This deep integration enables automated provisioning, scaling, and managing persistent volumes, making it ideal for stateful workloads like databases and observability platforms. Organizations can define storage characteristics through Kubernetes StorageClasses, allowing for granular control over performance, availability, and cost optimization.

Key Features:

  • Advanced thin provisioning that eliminates storage waste by allocating capacity only when needed
  • Intelligent storage pooling that automatically manages and scales underlying storage resources
  • Transparent tiering to move infrequently accessed data to cost-effective storage tiers
  • Ultra-low latency storage access through local NVMe device integration
  • Built-in encryption, compression, and multi-tenancy support
  • Cross-zone disaster recovery with near-zero RPO using write-ahead logging
  • Instant volume snapshots and clones for rapid database operations

simplyblock particularly excels in environments running multiple database workloads, offering consistent snapshots across various database types and enabling rapid cloning for development and testing. Its architecture is designed to meet the demands of organizations that require high-performance, scalable storage for their Kubernetes-based services.

Combining cutting-edge NVMe/TCP technology with intelligent storage orchestration, simplyblock delivers a modern storage solution that helps organizations maximize their Kubernetes investments while minimizing operational complexity and cost.
