Portworx Alternative
Take your Kubernetes storage to the next level with simplyblock
Simplyblock's multi-tier architecture delivers superior performance through local NVMe caching while significantly reducing storage costs with intelligent tiering and thin provisioning, making it ideal for companies looking to optimize their Kubernetes storage expenses without sacrificing speed or reliability. Based on NVMe/TCP protocol, simplyblock is the high-performance solution for your Kubernetes stateful workloads and one of the best alternatives to Portworx or other Kubernetes-native persistent storage solutions.
Challenges with Portworx
Cost-inefficiency
Portworx' reliance on replication for data protection leads to a minimum of 2x or 3x storage overhead which dramatically increases the storage cost compared to modern solutions that use efficient erasure coding for data durability.
Lack of QoS
Guarantees on access latency and IOPS for prioritized volumes and tenant isolation with IOPS and throughput quotas are key features of Enterprise Storage. Simplyblock is the first Kubernetes storage solution providing true enterprise-grade QoS for Kubernetes storage.
iSCSI or NVMe-RoCE
Portworx supports two storage protocols, iSCSI and NVME-RoCE. While iSCSI is an old and efficient protocol, RoCE or RDMA over Converged Ethernet isn't available in all network environments. Simplyblock is build on NVMe-of and NVMe/TCP standards.
No intelligent storage tiering
Simplyblock offers intelligent storage tiering that starts form where data sits (hyper-converged or disaggregated NVMe hot-tiers) and spans into large object storage pools or QLC clusters. Such solution can bring down storage TCO cost significantly with minimal impact on actual storage performance.
What is Simplyblock?
simplyblock is an intelligent storage optimizer that revolutionizes storage management by unifying access to NVMe storage, QLC pools, and object storage through a modern NVMe/TCP interface, delivering ultra-low latency performance while significantly reducing costs through advanced features like erasure coding and automated tiering. Unlike Portworx, which relies on costly full replication and older iSCSI technology, simplyblock's NVMe-first architecture provides superior performance with native multi-attach capabilities, all while consuming less storage through efficient data protection. Additionally, simplyblock operates seamlessly in air-gapped environments and uses modern protocols built into the Linux kernel, making it both more secure and more compatible across different network infrastructures than Portworx.
Deployment comparison
Both architectures, simplyblock and Portworx, offer a great deployment flexibility, supporting a disaggregated setup where storage runs in a dedicated cluster, as well as a hyperconverged model where storage and workloads share Kubernetes worker nodes. Simplyblock, however, adds a third deployment option, a hybrid approach combining the hyperconverged storage and disaggregated storage models for ultra low latency and infinite scalability.
Additionally, simplyblock enables the usage of NVMe over TCP (a protocol of the NVMe over Fabrics family) which is compatible with any Ethernet network, and the modern successor to the older iSCSI protocol, offering lower latencies and decreased protocol overhead.
Architecture comparison
Simplyblock takes a fundamentally different architectural approach than Portworx, building upon a modern NVMe-first design that intelligently consolidates different storage tiers (NVMe disks, cloud block storage, and object storage) behind a unified NVMe/TCP interface.
While Portworx relies on costly full replication with factors of 2 or 3 and older iSCSI technology, simplyblock achieves high availability through efficient erasure coding (similar to RAID-5) and delivers superior performance through local NVMe caching and modern NVMe/TCP protocol that's natively supported in the Linux kernel. This architecture enables simplyblock to provide ultra-low latency access while significantly reducing storage costs through intelligent thin provisioning and automated tiering to object storage like S3.
Benefits of Simplyblock?
Simplyblock improves the performance, the compatibility, and the cost-efficiency over Portworx.
Multi-tier architecture
While Portworx has basic HDD tiering capabilities, simplyblock offers true intelligent tiering solution that starts with NVMe caching nodes and expands into scalable object storage backends or QLC pools.
Enhanced Compatibility
Portworx offers connections to their volumes through iSCSI or NVMe over RoCE. While both protocols aren't bad solutions, compatibility, latency, and protocol overhead can significantly optimized using NVMe over TCP, utilized by simplyblock.
3x More Cost Efficient
Simplyblock achieves 3x better storage efficiency through modern erasure coding and intelligent tiering to HDD pools or object storage, compared to Portworx wasteful double or triple replication. This translates to dramatically lower storage costs while maintaining enterprise-grade data protection and durability.
