PowerScale was built for the data center. Nasuni was built for the cloud.
PowerScale ties your file data to a cluster and a refresh cycle. Nasuni delivers file services from your Azure, AWS, or Google Cloud object storage, with no cluster to refresh. See what that looks like against your current footprint.
Six things Nasuni does without the hardware dependency.
PowerScale’s strengths are tied to the cluster. Nasuni’s strengths come from not having one. When file data lives in object storage with lightweight virtual edges, the constraints of physical scale-out NAS go away.
Global file system, not a namespace
UniFS® lives in cloud object storage with a virtual edge in any site or cloud region, presenting the same files and same ACLs, with Global File Lock® to prevent version conflict.
Backup and DR built in
Continuous File Versioning® provides immutable recovery points every few minutes, with no limits. Object storage replication and stateless Nasuni Edges provide 15-minute DR in any site, with no second cluster required.
Ransomware detection at the edge
Integrated, real-time edge detection of known and zero-day attacks. Auto-mitigation isolates the source and restores only infected files in one click.
No refresh treadmill
Nasuni Edges use cloud resources or your existing virtual infrastructure. They don’t reach EOSL or wait on hardware procurement. Capacity expands by adding object storage, not nodes.
Any cloud, on your terms
Run on your Azure, AWS, Google Cloud, Oracle, or private object storage accounts, or multiple at once. Burn down your cloud commits. Reduce TCO up to 80%.
Distributed by design
A lightweight Edge in every site or cloud region that needs files, all reading from one authoritative source in object storage, with VPN-less and offline sync options for remote workers.
More PowerScale sites, more clusters. More Nasuni sites, one platform.
The shape of your file infrastructure determines what’s easy and what’s expensive. PowerScale puts everything inside the cluster and routes traffic to it. Nasuni puts data in cloud object storage and serves it from edges anywhere.
Centralized scale-out NAS
Performance lives in the cluster. Everything else routes back to it.
- Cluster lives in one data center
- DR requires a paired cluster + SyncIQ
- Capacity planning bounded by cluster
- Refresh cycle every 4–6 years
- Edge access via VPN or app proxy
Cloud-native file services
The data lives in object storage. The edges live wherever you need them.
- One file system, every location
- DR built in, restore in 15 minutes
- Capacity scales with Azure, AWS, or Google Cloud, or the object storage of your choice
- No node refreshes, ever
- Browser-based access, no VPN
- Runs in your cloud accounts, burns down your commits
- Integrated ransomware detection and recovery
Migrating off PowerScale is the easiest part of leaving it.
Most PowerScale customers don’t need another cluster. They need an exit from the refresh cycle. Nasuni’s migration team has moved petabytes of OneFS data into Azure, AWS, and Google Cloud object storage, preserving permissions, drive mappings, and user experience, without the rip-and-replace.
Discovery & assessment
Nasuni maps your existing PowerScale environment, OneFS volumes, and file activity patterns. You get a written migration plan and TCO comparison against your next refresh quote before any commitment.
Parallel provisioning
Nasuni Edges deploy in your Azure, AWS, or Google Cloud tenant, or on existing on-prem virtual infrastructure, alongside your PowerScale cluster. No new hardware to procure, no rack space to find.
Cutover with no downtime
OneFS data migrates in the background, preserving permissions and drive mappings. Users keep working through cutover. Your PowerScale refresh becomes a decommissioning exercise, not a procurement one.
