Hammerspace Tier 0

Use Server-Local NVMe Storage as a Shared High-Performance Tier

Leverage SSD capacity you already own to accelerate AI and HPC workloads - on-prem and in-cloud

Turn Stranded NVMe Capacity into Shared High-Performance Storage

Modern GPU and CPU servers include terabytes of high-performance NVMe storage, yet in most environments that storage remains largely underutilized because it is siloed and only accessible locally.

In a large compute cluster this could represent hundreds of terabytes or even petabytes of NVMe flash storage, which could be used for training, checkpointing, and inferencing.

A Hammerspace Tier 0 architecture transforms that server-local NVMe into a shared high-performance storage tier, activating flash capacity already deployed across the compute cluster as part of the Hammerspace Data Platform. The result is low-latency storage for AI and HPC workloads while reducing reliance on dedicated external flash infrastructure.

Tier 0 Highlights:

  • Delivers shared access to server-local NVMe across the cluster

  • Automated data orchestration between Tier 0 and capacity tiers

  • Standard NFS, SMB, and S3 access

  • No client or agent to install on the compute nodes

  • Capacity can be brought online in hours

Unify, Orchestrate, Accelerate: How Hammerspace Works

Transform your distributed storage into a single, high-performance Global Namespace. Hammerspace seamlessly assimilates your existing infrastructure in minutes, uses intelligent policies to automate data placement, and delivers ultra-low latency data directly to your most demanding AI and HPC workloads—all without disruptive migrations.

  • Step 1: Configure Tier 0

    Add server-local storage volumes to Hammerspace. Set data policies to determine data protection, placement, and tiering.
  • Step 2: Automate Data Flow

    Data is written directly to local NVMe, bypassing network bottlenecks. Files are mirrored across the cluster for protection, and tiered to external storage based on policy. 
  • Step 3: Unlock Performance

    Write to, and read from, local storage at the highest-bandwidth and lowest-latency. Tier data to external storage based on policy.

Unlock the Fastest Storage to Maximize GPU Utilization, Boost Throughput and Reduce Latency

AI infrastructure performance increasingly depends on how quickly data can be delivered to GPUs. A Hammerspace Tier 0 architecture transforms server-local NVMe into a shared high-performance storage tier, placing data closer to compute resources and reducing the latency and I/O bottlenecks associated with external shared storage.

In real-world performance benchmarking, Tier 0 architectures have demonstrated 4.4x higher throughput, 56% lower latency, and 66% faster checkpoint saves relative to external shared storage.

SSD Crisis Survival Guide

Reduce Flash Infrastructure Requirements by Leveraging SSDs You Already Own

While a Tier 0 architecture does not eliminate the need for external storage, it can reduce the amount of dedicated flash infrastructure required to support AI and HPC workloads. By activating NVMe capacity already deployed across the compute environment, organizations can reserve new flash investments for workloads that truly require them, reducing storage costs, power consumption, and rackspace requirements. In large-scale GPU and AI environments, the operational and infrastructure savings can be substantial.
