network all working together in the environment.
11.3.3 Complete Cluster View
The complete cluster is combined with hardware, software, networks, as
shown in Figure 11.2. It depicts the complete architecture; software, hard-
ware, and network all working together in the environment with servers to
provide a completely distributed single file system that can scale dynamically
as workloads and capacity needs or throughput needs change in a scale-out
environment.
11.4 OneFS Software Overview
11.4.1 Operating System
OneFS is built on a BSD-based operating system foundation. It supports
both UNIX and Windows semantics natively, including hard links, delete-on-
close, atomic rename, access control lists (ACLs), and extended attributes. It
uses BSD as its base operating system because it is a mature and proven oper-
ating system and the open-source community can be leveraged for innovation.
11.4.2 File System Structure
The OneFS file system is based on UFS and, hence, is a very fast, dis-
tributed file system. Each cluster creates a single namespace and file system.
This means that the file system is distributed across all nodes in the cluster
and is accessible by clients connecting to any node in the cluster. There is no
