VAST Data Alternative

Supercharge Your Storage Performance

Searching for a VAST Data alternative that delivers high throughput and ultra-low latency without being locked into proprietary infrastructure? Simplyblock™ is the answer: an NVMe-first block storage engine designed to maximize IOPS per core, eliminate overhead, and accelerate workloads with NVMe-over-TCP—no RDMA required.

Challenging Performance with VAST Data

Hardware Dependence

VAST requires proprietary hardware, limiting optimization flexibility across diverse environments.

No CPU-Per-IO Efficiency

VAST doesn't optimize for IOPS per CPU core, limiting the amount of maximum achievable IOPS.

Unoptimized Client Protocols

Clients access VAST via NFS, SMB, and an S3-compatible API, limiting access latency and throughput.

What makes Simplyblock™ Different?

⚙️ Deployment Comparison

Simplyblock delivers industry-leading performance with up to 250,000 IOPS per CPU core and sub-millisecond latency, thanks to its end-to-end NVMe-over-TCP architecture that runs natively in the Linux kernel. Unlike RDMA-based systems, it requires no special hardware, reducing both complexity and cost.

Its deployment model is highly flexible—supporting hyperconverged, disaggregated, and hybrid setups—ideal for Kubernetes-native environments where performance and scalability must go hand in hand.

VAST Data, by contrast, depends on appliance-based, disaggregated deployments and RDMA networks for performance, which introduces vendor lock-in and higher infrastructure overhead. While capable of low latency, its scalability and adaptability are limited by its hardware-bound design.

Simplyblock offers the same or better performance, with far greater deployment freedom and efficiency.

🧱 Architecture Comparison

Simplyblock is built around a minimal, high-performance architecture with a containerized storage engine and a native Kubernetes CSI driver. This design delivers sub-millisecond latency and up to 250,000 IOPS per core, thanks to its use of NVMe-over-TCP—a protocol natively supported by the Linux kernel. It eliminates the need for RDMA, reducing complexity while maintaining exceptional throughput.

VAST Data, on the other hand, relies on a layered appliance architecture using QLC flash, SCM, and metadata servers. While it delivers strong performance, it’s tightly coupled to proprietary hardware and requires RDMA for optimal operation. This adds cost, limits flexibility, and complicates deployment in modern, cloud-native environments.

Simplyblock offers similar or better performance with greater efficiency, simpler operations, and no hardware lock-in.

Why Customers Love Simplyblock
