Dell ObjectScale
Dell's Kubernetes-native S3-compatible object storage platform — a container-architecture rebuild of the Dell ECS codebase — and, as of 2026, the second named production platform shipping GPUDirect RDMA KV-cache offloading, merged upstream into vLLM and LMCache.
Summary
Dell's Kubernetes-native S3-compatible object storage platform — a container-architecture rebuild of the Dell ECS codebase — and, as of 2026, the second named production platform shipping GPUDirect RDMA KV-cache offloading, merged upstream into vLLM and LMCache.
ObjectScale is where the KV-cache-on-object-storage pattern reaches enterprise-owned infrastructure: vLLM/LMCache deployments can offload computed KV tensors to a Dell object tier over S3-HTTP or S3-over-RDMA without bespoke integration. Its existence as a *second* vendor deployment (after CoreWeave/Cohere) is what moves the pattern from anecdote toward standard architecture.
- ObjectScale is not a rename of ECS — it's a Kubernetes-native rebuild; Dell ships both on the same codebase for different workload shapes.
- Check the 2026 security-advisory history before deployment: default-credentials and hard-coded-credentials CVEs are fixed only in ObjectScale 4.2.0.0/4.3.0.0+.

Definition
Dell's Kubernetes-native, S3-compatible object storage platform — a full container-architecture rebuild of the Dell ECS codebase, not a rename — spanning software-defined deployments and the XF960 all-flash appliance. Its 2026 significance for this index: ObjectScale is the second named production platform to ship GPUDirect RDMA KV-cache offloading for S3-compatible storage, with the capability merged upstream into vLLM and LMCache.
Enterprises running AI serving want the KV-cache-on-object-storage pattern (proven by the CoreWeave/Cohere deployment) on infrastructure they own. ObjectScale wires the S3-HTTP and S3-over-RDMA paths into the standard open-source inference stack, so a vLLM or LMCache deployment can offload computed KV tensors to a Dell object tier without bespoke integration — bypassing S3-HTTP overhead and using the RDMA fabric directly.
On-prem/hybrid S3-compatible storage for cloud-native workloads, KV-cache offload target for vLLM/LMCache inference fleets, GPUDirect RDMA data paths into Dell storage, upgrades from ECS 3.8.x/4.0.x deployments.
