Pricing

Enterprise pricing is primarily capacity/data-under-management based and may be sold as subscription or perpetual licensing. Cloud marketplaces support usage-based PAYGO and BYOL models. AWS Marketplace lists PAYGO capacity pricing from $0.114/TB/hour for 10-99.9 TB down to $0.014/TB/hour for 100,000-100,000,000 TB. On-premises enterprise pricing is generally quote-based.

Differentiators

  • —Unifies existing file and object storage across data centers, clouds, and edge sites through a single global namespace.
  • —Orchestrates data to the location of compute without requiring a wholesale storage migration or infrastructure replacement.
  • —Uses Linux-native, standards-based protocols and does not require a proprietary client for its Tier 0 deployment.
  • —Tier 0 can use GPU-server-local NVMe as shared, high-performance storage; Hammerspace claims up to 10x the speed of external networked storage in applicable workloads.
  • —Combines data access, global placement, tiering, and copy reduction across geographically distributed environments.
  • —Designed to keep GPUs supplied with data and improve time-to-first-token, training, inference, and HPC performance.
  • —Can operate across on-premises systems, AWS, Azure, Google Cloud, OCI, and partner hardware.
