Flexible
EOS is a storage solution for central data recording, analysis and processing++
Adaptable and Scalable
EOS supports thousands of clients with random remote I/O patterns with multi protocol support
WebDAV, CIFS, FUSE, XRootd, GRPC.
Over 930 PB at CERN
Designed for high capacity and low latency.
Security
EOS offers a variety of authentication methods:KRB5, X509, OIDC, shared secret, and JWT and proprietary token authorisation.
Sync & Share
EOS provides Sync&Share functionality for the CERNBox front-end services.
Tape Storage
EOS includes tape storage in combination with the CTA Cern Tape Archive software.
Service Architecture
EOS splits into client and server side components
Clients
The EOS client provides a command line interface and a mounted filesystem interface.
Server
The EOS server is divided into meta-data and data storage components and persistency back-ends.
EOS is based on various open source components. The native protocol and framework used for implementation is XRootD. Meta-data is persisted in RocksDB databases using a proprietary KV store called QuarkDB. Data is stored natively in XFS filesystems on hard disks or SSDs or on virtualised back-end storage (e.g. RADOS block devices) or distributed filesystems like Lustre or CephFS.

9th EOS Workshop at CERN
This two event is organized to provide a platform for exchange between developers, users and sites running EOS. The workshop will cover a wide range of topics related to EOS development, operations, deployments, applications, collaborations and various use-cases!
CERN passes an Exabyte of Disk Storage
End of 2023 CERN's disk storage capacity has reached 1 exabyte! Most of the capacity is managed by EOS services!
