Elastx Migrates to Lightbits Software-Defined Storage, Ditching Proprietary PMem
Event summary
- Elastx expands its cloud platform using Lightbits LightOS software-defined block storage, replacing Intel Optane PMem with standard NVMe SSDs.
- The deployment supports Elastx’s transition to a fully software-defined journaling model for high-performance workloads and AI applications.
- Lightbits’ journaling capability persists writes to SSD before committing them to primary storage, improving resilience and reducing hardware dependencies.
- Elastx leverages Lightbits’ SSD-based journaling to maintain sub-millisecond latency and high throughput while simplifying hardware procurement.
- The move reflects a broader industry trend of replacing proprietary infrastructure components with software-defined alternatives on commodity hardware.
The big picture
Elastx’s migration to Lightbits’ software-defined storage underscores a broader industry shift toward hardware-agnostic solutions. As SSD costs rise and supply chains remain volatile, cloud providers are increasingly turning to software-defined architectures to improve cost economics and operational flexibility. This trend is particularly relevant for high-performance workloads and AI-driven applications, where resilience and low latency are critical.
