Ceph / Rook Alternative

Increase performance and reduce complexity and cost with Simplyblock

Simplyblock simplifies operational complexity, improves cost-efficiency, and delivers powerful performance for your IO-intensive storage workloads inside and outside Kubernetes. Your mission-critical data deserves a modern block storage solution that you confidently run as an alternative to Ceph / Rook.

Simplyblock Architecture

Challenges with Ceph

Not a feature

Operational Complexity

Ceph deployments demand dedicated storage teams to manage their complex architecture of monitors, OSDs, and metadata servers, with scaling and upgrades requiring careful orchestration.

Not a feature

Legacy Architecture

Ceph's architecture was designed for spinning disks in the pre-cloud era, making it inefficient for modern NVMe storage and leading to poor CPU utilization and limited IOPS performance on flash storage.

Not a feature

Performance Bottleneck

Ceph deployments demand dedicated storage teams to manage their complex architecture of monitors, OSDs, and metadata servers, with scaling and upgrades requiring careful orchestration.

Not a feature

Cost-Inefficiency

Ceph's reliance on triple replication for data protection leads to a minimum 3x storage overhead, dramatically increasing costs compared to modern solutions that use efficient erasure coding for data durability.

What is Simplyblock?

Simplyblock is a modern storage orchestrator, built specifically for NVMe and cloud-native stateful workloads, delivering up to 50x more IOPS per CPU core and 5x better storage efficiency than Ceph. Unlike Ceph's legacy architecture, simplyblock provides enterprise features like instant snapshots, automated S3 tiering, and near-zero RPO disaster recovery, all while reducing storage costs by up to 75%. Learn why simplyblock is the perfect replacement for Ceph / Rook.

Deployment comparison

Simplyblock's modern architecture offers unparalleled deployment flexibility, supporting three distinct models: a disaggregated setup where storage runs in a dedicated cluster, a hyperconverged model where storage and workloads share Kubernetes worker nodes, and a hybrid approach combining both. This flexibility allows organizations to optimize for their specific needs - using hyperconverged for maximum performance with local NVMe, disaggregated for independent scaling of storage and compute, or a hybrid model balancing both approaches.

In contrast, Ceph's legacy architecture essentially mandates a standalone cluster deployment, forcing a rigid separation between storage and compute resources. This architectural limitation not only increases operational complexity but also prevents organizations from taking advantage of hyperconverged efficiencies when desired. While Ceph's standalone model made sense in the era of spinning disks, it fails to leverage the full potential of modern NVMe storage and cloud-native deployment patterns that simplyblock's flexible architecture enables.

Architecture comparison

Simplyblock employs an elegantly simple, fully containerized architecture built around just two core components. The storage plane container handles all essential storage services including logical volume management, orchestration, tiering, and data protection, while a single CSI driver container provides seamless Kubernetes integration. This streamlined design not only simplifies deployment and operations but also reduces potential points of failure and management overhead.

A great alternative to Ceph simplifies the complexity, and simplyblock does just that.

In stark contrast, Ceph relies on a complex architecture requiring multiple specialized services - monitors for cluster state, OSDs for data storage, metadata servers for file system operations, and separate CSI drivers - each running in their own containers. This multi-layered approach significantly increases operational complexity, requiring careful coordination between components and deep expertise to maintain, troubleshoot, and scale effectively. The complexity of Ceph's architecture often necessitates dedicated storage teams and extensive training just to keep the system running optimally.

Benefits of Simplyblock?

Simplyblock delivers significantly more performance and is significantly more cost-efficient than Ceph.

50x More IOPS

While Ceph struggles with 4,000-8,000 IOPS per CPU core due to its legacy architecture, simplyblock's modern NVMe-first design delivers up to 250,000 IOPS per core, making it the ideal choice for high-performance database workloads in cloud environments.

30x Lower Latency

Simplyblock achieves sub-millisecond latency under 0.1ms through its NVMe-first architecture, while Ceph's legacy design struggles with 30x higher latencies. This dramatic performance difference makes simplyblock the superior choice for latency-sensitive database workloads.

5x More Storage Efficiency

Simplyblock achieves 5x better storage efficiency through modern erasure coding and intelligent tiering to S3, compared to Ceph's wasteful triple replication. This translates to dramatically lower storage costs while maintaining enterprise-grade data protection and durability.
