XtreemFS

XtreemFS is a distributed file system for wide area networks. XtreemFS provides fault tolerance while maintaining POSIX file system semantics. Fault tolerance is achieved by using Paxos-based lease negotiation algorithms and is used to replicate files and metadata.

File-based solutions provide humans with a way to store and collaborate around files organized through a hierarchy of folders. Read more.

interface

Interface

File systems are better suited for accessing storage infrastructure with large amounts of data since, unlike file synchronization, the files do not need to be downloaded locally first but can be accessed on-demand. Read more.

model

Model

Distributed storage systems distribute the data between a set of storage servers while some specific metadata server control the overall infrastructure, possibly acting as single points of failure and/or bottlenecks. Read more.

Environment

A controlled environment is a set of servers and clients that are under the control of a single entity e.g a company. Read more.

redundancy

Redundancy

Replication is a simple redundancy mechanism that consumes more storage capacity than erasure codes but are more adapted to primary storage.

fault_tolerance

Fault Tolerance

The ability to maintain a storage system operational depends on algorithms that need to adapt depending on the nature of the environment. Read more.

security

Security

Every communication is encrypted (in transit) but data, once stored, is not (at rest). Read more.

scalability

Scalability

Homogeneous systems can scale up and out but are limited to resources that are under the control of the infrastructure's administrator: local disk, NAS etc. Read more.

interoperability

Interoperability

The ways a user or program can interact with a storage system; either through specific desktop/mobile applications or standard protocols. Read more.
