AOS Storage
A Modern Storage Fabric
Replace your SAN and NAS with highly-automated, performant, software-defined storage that scales with your applications whether on-prem or in the cloud
Modern storage for all applications at any scale
AOS Storage is the scale-out storage technology that makes HCI and cloud possible, delivering enterprise-grade capabilities via a highly distributed software architecture
Performance
High performance software-defined architecture using modern storage media, like NVMe, delivers speeds similar to a SAN.
Resilience
Advanced software algorithms protect data from hardware failures to total site outages.
Scale
Performance and capacity scale linearly and data is automatically distributed as new capacity is added.
How AOS Storage works
Features
Performance
Data locality
Data locality provides high performance. When data is written by an application, one copy is stored locally so it can be retrieved without needing to access the network. This ensures the lowest possible latency and prevents the network from becoming congested.
Intelligent tiering
The storage environment continually monitors data access and automatically optimizes data placement on either SSD or HDD tiers, resulting in optimal performance without the need for manual intervention or troubleshooting.
High-throughput
The latest memory class storage technologies, like NVMe, deliver high throughput and fast response times compared to traditional SATA or SAS technology.
Resilience
Granular and efficient snapshots
Metadata-based local snapshots with virtual machine and application-level consistency recover data instantly to meet a wide range of RTO and RPO requirements.
Automatic self-healing
AOS Storage is designed to automatically self-heal in the event of SSD, HDD/NVMe device, or node failures. It can also fully recover the management stack without requiring any user intervention or causing delays.
Tunable redundancy
AOS Storage absorbs incoming writes onto fast, low latency SSD tier. Data is then written to back-end storage resources asynchronously. This process ensures data exists in at least two independent locations in the cluster, making it fault-tolerant.
Scale
Easy scale-out
AOS Storage allows organizations to start with the infrastructure they need today, and effortlessly scale out as application and business needs evolve.
Independently scale
Independently scale storage or compute resources helps fine tune requirements for applications with different needs and hypervisors.
Fast provisioning
Storage policies are easily created and attached to VMs allowing instantaneous access to dynamic storage pools as capacity is added.
How it works
AOS Storage simplifies storage for virtual and container environments by pooling the storage devices that are directly attached to a cluster of servers and presenting them to applications across a variety of storage protocols. Data is managed and protected by a fine-grained, distributed metadata system. It ensures that data is stored and accessed efficiently, while also providing robust protection against data loss or corruption.
