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.
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 OneBlox) 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 21.
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.
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 19.
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).
Hard Link In computing, a hard link is a directory entry that associates a name with a file on a
file system. (A directory is itself a special kind of file that contains a list of such
entries.) The term is used in file systems which allow multiple hard links to be created
for the same file. This has the effect of creating multiple names for the same file,
causing an aliasing effect: e.g., if the file is opened by one of its names, and changes
are made to its content, then these changes will also be visible when the file is
opened by an alternative name.
NFS Network File System is a distributed file system protocol originally developed by Sun
Microsystems in 1984, allowing a user on a client computer to access files over a net-
work much like local storage is accessed. NFS, like many other protocols, builds on
the Open Network Computing Remote Procedure Call (ONC RPC) system. The Net-
work File System is an open standard defined in RFCs.

OneBlox
®
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 OneBlox failure.
Ring Multiple interconnected OneBlox (up to 7 OneBlox) in a local area network that pres-
ent 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 which Storage Shares Users have Access to—Adding Shares”on page 91.
Snapshots Snapshots of data are taken continuously and can be viewed by date or by most
recent. See “Viewing Snapshots”on page 94.

4.1 - Network Information
OneBlox 4312 has 2 x 10GbE BASE-T and 2 x 1 GbE ports available to the network. An additional
2 x 10GbE SFP+ ports are optional.
OneBlox uses a balance-alb networking protocol to present a single IP address from the Ring,
even if multiple OneBlox are in the same Ring. Each OneBlox can be assigned either reserved
DHCP or Static IP addresses. Admins may assign a Virtual IP address for the Ring that will resolve
application and client connections to any OneBlox in the Ring if applications have difficulty with
mDNS or NETBIOS.
4.2 - Storage Management
4.2.1 - How to Access Information on OneBlox
When connecting OneBlox to the network, a Public share is accessible to anyone on the network.
Any information stored in the public share can be accessed and modified by individuals on the
network.
Administrators, through OneSystem, can define permissions for different users to have different
levels of access (read only vs. read/write) to different shares on the network. Administrators can
add/remove shares, groups and/or users through their OneSystem account. If companies are
using Microsoft Active Directory, OneSystem can be integrated with Active Directory and utilize the
existing access control permission a company is using.
To access OneBlox, it can be done over the local area network (LAN) and seen through Windows
Explorer, Mac Finder, or Linux. It appears as a drive or share to the users and applications.
4.2.2 - Protecting the Information on OneBlox
OneBlox's file system protects all information stored in a number of ways. OneBlox protects
against data deletion/corruption, drive removal, drive failures, OneBlox failures, and ring failures.
OneBlox takes continuous snapshots of information being stored in OneBlox. In doing so, each
user has access to previous versions of the files stored in OneBlox, even up to the last few
seconds. Users can access the snapshot directory through Windows Explorer or Mac Finder and
recover exactly the needed file themselves without requiring the assistance of an administrator.
The continuous protection provides the ability to go back to the last file written to OneBlox (which
could be the last few seconds), as well as further back in time: the last minute, hour, day, week,
month, or year(s).
OneBlox protects against drive failures by creating three replicated copies of every file written to
OneBlox. By creating three copies, any two drives can fail and users will still have access to the
information. OneBlox doesn't use a legacy RAID protection scheme, so administrators don't need
to be concerned with volumes, storage LUNs, drive types, or drive capacities. OneBlox manages
this complexity for the administrator.
When a single OneBlox is used, OneBlox creates three replicated copies of the information on the
single OneBlox. When multiple OneBlox are used, OneBlox, intelligently, load balances and
distributes the copies of information across multiple OneBlox. When three or more OneBlox are
used in a ring, two OneBlox can fail and users will still have access to the information. A OneBlox
failure may be a result of a hardware failure (e.g., network, memory, power supply). In each case
the information is protected.
If your company is concerned about a site failure, a ring (up to 7 interconnected OneBlox) may be
replicated to another ring over local or wide-area distances in a mesh. In the event of one site
C
HAPTER
4 : Concepts OneBlox 4312 User Guide
Understanding OneBlox and OneSystem | Version 2.15.5 | page 19
going offline, the other site has additional copies of the information and users can access the
information from the alternate ring.
4.2.3 - How to Increase the Storage Capacity
OneBlox provides the ability to dynamically grow the size of the ring in a number of ways.
Individual drives can be added to a single OneBlox if there are available drive bays. Alternatively,
an existing drive in OneBlox can be removed and replaced with a larger capacity drive.
In addition to drive growth, additional OneBlox can be added. This is a similar process to the first
OneBlox addition, but simpler. Refer to Chapter 1, “Quick Start”on page 7 for OneBlox installation.
If the OneBlox is added to the same LAN as an existing OneBlox, it will dynamically join the
existing OneBlox(s) and the single file system accessible by applications and users now have
access to the capacity of the new OneBlox without any configuration changes.
4.2.4 - Space Savings
OneBlox efficiently stores information in OneBlox. Every file written to OneBlox is deduplicated.
Every file, and every portion of a file that is written is compared to files already stored on OneBlox.
If the same file (or portion) is already stored a duplicate is not written to OneBlox. This
dramatically improves the amount of usable capacity available to applications and users.
In addition to the information being deduplicated, the snapshots are also deduplicated resulting in
further increases in usable capacity.
4.3 - Storage Capacity Reporting through OneSystem
4.3.1 - Used Capacity
Used storage capacity is the amount of storage (or capacity) that has been consumed by
applications and/or users when data protection is taken into account. As OneBlox creates three
replicas of the information, the used capacity increases accordingly. With data deduplication, the
available storage capacity is typically increased with object-based global deduplication.
4.3.2 - Free Capacity
Free capacity is the amount of storage (or capacity) that is available to applications and/or users.
This value does not take into account data protection or deduplication. For example, if there is
6TBs of free capacity and an application writes 1TB of 100% unique data (resulting in zero
deduplication), the free capacity will be reduced to approximately 3TB. (There are three copies of
the 1TB of data to protect against two drive or two OneBlox failures.)
4.3.3 - Raw Capacity
Raw storage capacity is the total capacity installed in the OneBlox Ring. The raw capacity accounts
for the OneBlox filesystem and will be slightly less than the 'unformatted drive capacity' seen in
each OneBlox view of OneSystem. Raw capacity will be greater than the available storage capacity
that is presented to applications and users.
4.3.4 - Unformatted Drive Capacity
Unformatted drive capacity is the sum of the capacity of each drive in OneBlox and does not
account for any OneBlox filesystem formatting or overhead.

4.3.5 - Available Capacity
Available storage capacity is the free capacity presented to applications. Available capacity will be
the capacity a given application may write to the OneBlox Ring. The available capacity does not
take into account any data protection or deduplication. Consequently, an application that sees 1TB
of available capacity and writes 1TB of data that is 100% deduplicated, it will see 1TB of available
capacity at the conclusion of the new writes.
4.4 - Storage Capacity Reported to Applications
OneBlox’s object-based storage architecture enables OneSystem to report storage capacity
utilization information in two meaningful ways:
•OneSystem admins will see the pertinent physical disk storage information (the drive capacity
that does not take into account the OneBlox filesystem, deduplication, or data protection).
•OneSystem admins will also see the information from the application’s perspective. This is an
updated view into capacity planning and with OneBlox 2.6, applications will be able to more
accurately understand total, free, and used storage capacity.
4.4.1 - Filesystem Capacity Reporting
For filesystem capacity reporting, there are also three terms to understand.
1.
Total Storage Capacity is the maximum amount of information that can be written to the
OneBlox file system after accounting for the filesystem overhead and data protection. Since all
information is protected by storing three copies within a Ring, the total storage capacity will be
reported as 1/3 the Total Disk Capacity. This value can also be seen from the application.
