High-Performance Computing Storage That's Easy to Manage

HPC admins have to deal with a wide variety of applications and home-grown code that produces various IO patterns. With Auto File Layouts Quobyte writes small files on flash with replication and then seamlessly switches to erasure coding (on HDD or flash) as the file grows. This optimizes performance and space utilization for all types of applications and even mixed file sizes.

With synchronous replication and erasure coding for data protection, you can run all workloads on Quobyte, including VMs and databases. In addition, Quobyte brings a range of enterprise features to HPC such as encryption, snapshots, file immutability, and multi-tenancy.

Quobyte runs on-prem or in the cloud. With our tools like volume mirroring and the data mover you can sync clusters in different data centers, including in the cloud. Read more about the Quobyte data mover here.

Striped files use the aggregated performance of several servers and can deliver 10s of GB/s on a single file. Striping works for replicated files and is always enabled for erasure-coded files.

All aspects of Quobyte can be controlled through the API, making it easy to automate storage operations from provisioning volumes to charge back to users.

Protect your storage from unauthorized access without having to trust the network. Admins can restrict certificates to specific users, similar to a root squash. This allows users that have root access on their workstations to access the storage as just that user.

Quobyte comes with a range of enterprise-level security features for demanding HPC applications, e.g. when HIPAA compliance is needed, or when dealing with personal data: End-to-end AES encrypted volumes, NFSv4 ACLs that are enforced across all platforms or TLS protected communication.

Quobyte quotas have been designed for scalability and minimal performance impact. Admins can configure quotas per storage tier for capacity, the number of files, and volumes for users, groups, a volume, or tenants. Default quotas can be configured on the same levels, per tenant.

Quobyte supports file range locks (fcntl) and Windows file locks. Locks are handled in a decentralized fashion for maximum scalability.

Snapshots creation and expiration can be configured through policies and by volume (e.g. only for home volumes). Snapshots are user-accessible and are connected to S3/object versions.

Quobyte implements fairness between IO streams (files), between large and small writes, and metadata operations from different users. This ensures that a single user can't monopolize the storage system.

Detailed per-application performance analytics tell you in real-time what's happening on the cluster. This includes information about IOPS, throughput, file creates, deletes, readdirs, and more.
