2.4 - Important Terms
Microsoft Active Directory Active Directory (AD) provides a central location for network administration and secu-
rity. Servers that run Active Directory are called domain controllers. An AD domain
controller authenticates and authorizes all users and computers in a Windows domain
type network-assigning and enforcing security policies for all computers and installing
or updating software. For example, when a user logs into a computer that is part of a
Windows domain, AD checks the submitted password and determines whether the
user is a system administrator or normal user. OneSystem enables administrators to
authenticate against an AD domain. See “Active Directory” on page 19.
Active Connections Number of active users connected to the OneBlox ring at a given time
CIFS/SMB The Common Internet File System (CIFS) is the standard communication protocol
servers and clients use to access files on OneBlox. One section of the Server Messag-
ing Block (SMB) protocol specifically deals with access to file systems, such that cli-
ents may make requests to a file server over the network.
Component Health Reflects health of a ring (comprised of one or more nodes) with regards to compo-
nents such as disks, ethernet cable, power, and so on.
Continuous Data Protection
(CDP)
An advanced technique to protect every file that is written to OneBlox. See “Continu-
ous Data Protection” on page 18.
Data Health Reflects the health of the data with regards to the number of copies of data available
in the ring(s). If the number of copies is less than the desired protection level (e.g., 3
copies) or the data is being rebuilt or rebalanced, the data health will indicate the
appropriate status.
Encryption All data and information stored in OneBlox is protected with an AES 256 algorithm,
which requires a unique key to be able to be read. This prevents a disk drive from
being removed and read on another device other than OneBlox.
Deduplication This is a method by which identical user data (or portions of identical data) is
detected and stored only once. See “Space Savings” on page 17.
Group A collection of user(s) can be assigned and organized into a collection of individuals to
make policy actions easier (e.g., group A has access to storage share A on the net-
work).
OneSystem
TM
100% Cloud-based data management service used to manage OneBlox.
Node A single OneBlox appliance.
OneBlox
TM
A physical storage hardware appliance to store and retrieve information.
Protected Capacity The total amount of storage that is configured and available to applications and users
within a ring. The raw storage capacity will be greater than the amount of protected
capacity. Protected capacity is analogous to usable capacity.
Protection Level The number of replicated copies of information within a ring or mesh providing a way
to recover information in the event of disk drive or node failure.
Ring Multiple interconnected OneBlox nodes (up to 6 nodes) in a local area network that
present a single file system to applications and users.
Share The CIFS/SMB method of providing access to the file system. A file system can con-
tain any number of shares. A share can be thought of as a partition of the file storage
area with three levels of access: 'Anyone,' 'All Registered', and 'Restricted'. See “How
do I Limit what Storage Shares Users have Access to—Adding Shares” on page 36.
Snapshots Snapshots of data are taken continuously and can be viewed by date or by most
recent. See “Viewing Snapshots” on page 37.
User Individual(s) with access to the network and consequently access to the public share
on OneBlox. The individual(s) can also be given different permissions and privileges to
access additional shares on OneBlox.
