1 Overview
HP 3PAR Storage Concepts and Terminology
HP 3PAR storage systems include the hardware components that physically store your data and
the software applications that manage your data. For more information about hardware platforms,
see “HP 3PAR Storage System Hardware” (page 61). For more information about system software
applications and features, see “HP 3PAR Software” (page 9).
The HP 3PAR storage system is composed of the following logical data layers:
•“Physical Disks” (page 8)
•“Chunklets” (page 8)
•“Logical Disks” (page 8)
•“Common Provisioning Groups” (page 8)
•“Virtual Volumes” (page 8)
The relationship between HP 3PAR storage system data layers is illustrated in Figure 1 (page 7).
Each layer is created from elements of the layer above. Chunklets are drawn from physical disks,
logical disks are created from groups of chunklets, common provisioning groups (CPGs) are groups
of logical disks, and virtual volumes use storage space provided by CPGs. The virtual volumes are
exported to hosts and are the only data layer visible to hosts.
Figure 1 HP 3PAR Storage System Data Layers
HP 3PAR Storage Concepts and Terminology 7

Physical Disks
A physical disk is a hard drive mounted on a drive magazine located in an HP 3PAR storage
system drive cage. For more information about physical disks and the HP 3PAR storage system
hardware platforms, see “HP 3PAR Storage System Hardware” (page 61).
Chunklets
Physical disks are divided into chunklets. Each chunklet occupies contiguous space on a physical
disk. On F-Class and T-Class systems all chunklets are 256 MB. On 10000 and 7000 systems all
chunklets are 1 GB. Chunklets are automatically created by the HP 3PAR Operating System and
they are used to create logical disks. A chunklet is assigned to only one logical disk. For more
information about chunklets, see “Chunklets” (page 32).
Logical Disks
A logical disk is a collection of physical disk chunklets arranged as rows of RAID sets. Each RAID
set is made up of chunklets from different physical disks. Logical disks are pooled together in
Common Provisioning Groups (CPGs) which allocate space to virtual volumes. The underlying
logical disks are automatically created by the HP 3PAR OS when you create CPGs. The RAID type,
space allocation, growth increments and other logical disk parameters can be set when you create
a CPG or modified later. HP 3PAR storage systems support the following RAID types:
•RAID 0
•RAID 10 (RAID 1)
•RAID 50 (RAID 5)
•RAID MP (Multi-Parity) or RAID 6
For a detailed discussion of logical disks and RAID types, see “Logical Disks” (page 34).
Common Provisioning Groups
A CPG is a virtual pool of logical disks that allocates space to virtual volumes on demand. A CPG
allows virtual volumes to share the CPG resources. You can create fully provisioned virtual volumes
(FPVVs) and thinly-provisioned virtual volumes (TPVVs) that draw space from a CPG logical disk
pool. For more information about CPGs, see “Common Provisioning Groups” (page 39).
Virtual Volumes
Virtual volumes draw their resources from CPGs, and volumes are exported as logical unit numbers
(LUNs) to hosts. Virtual volumes are the only data layers visible to the hosts. You can create physical
copies or virtual copy snapshots of virtual volumes that remain available if the original base volume
becomes unavailable. Before creating virtual volumes, you must first create CPGs to allocate space
to the virtual volumes. For more information about virtual volumes, see “Virtual Volumes” (page 42).
Fully-provisioned Virtual Volumes
An FPVV is a volume that uses logical disks that belong to a CPG. Unlike TPVVs, FPVVs have a set
amount of user space that is allocated for user data. The FPVV size is fixed, and the size limit is
16 TB. For more information about fully provisioned virtual volumes, “Fully-Provisioned Virtual
Volumes” (page 43).
Thinly-provisioned Virtual Volumes
A TPVV is a volume that uses logical disks that belong to a CPG. TPVVs associated with the same
CPG draw space from the logical disk pool as needed, allocating space on demand in small
increments for each controller node. As the volumes that draw space from the CPG require additional
storage, the HP 3PAR OS automatically creates additional logical disks and adds them to the pool
until the CPG reaches the user-defined growth limit which restricts the CPG maximum size. The
8 Overview

TPVV volume size limit is 16 TB. For more information about TPVVs, see “Thinly-Provisioned Virtual
Volumes” (page 43).
NOTE: Creating TPVVs requires the HP 3PAR Thin Provisioning Software license. For more
information, see “HP 3PAR Software” (page 9).
Physical Copies
A physical copy is a full copy of a volume. The data in a physical copy is static; it is not updated
with subsequent changes to the parent volume. The parent volume is the original volume that is
copied to the destination volume. The parent volume can be a base volume, volume set, virtual
copy, or physical copy. Creating physical copies does not require a separate license.
A physical copy can be created only from a parent volume with enough free space to accommodate
writes to that volume during the physical copy operation. Physical copies can be online physical
copies or offline physical copies. For online physical copies, the destination volume is automatically
created and can be exported immediately. Offline physical copies require a destination volume
that must have a user space size at least as large as the user space of the base volume being
copied, and offline physical copies cannot be exported.
For additional information about physical copies, see “Physical Copies” (page 45).
NOTE: With an HP 3PAR Remote Copy Software license, physical copies can be copied from
one HP 3PAR storage system to another by using Remote Copy. For additional information, see
the HP 3PAR Remote Copy Software User’s Guide.
Virtual Copy Snapshots
A snapshot is a virtual copy of a base volume. The base volume is the original volume that is
copied. Unlike a physical copy, which is a duplicate of an entire volume, a virtual copy only
records changes to the base volume. This allows an earlier state of the original virtual volume to
be recreated by starting with the current state of the virtual copy and rolling back all the changes
that have been made since the virtual copy was created.
You can make snapshots of: FPVVs, TPVVs, physical copies, or another virtual copy snapshot.
Snapshots are created by using copy-on-write techniques available only with the HP 3PAR Virtual
Copy Software license. Thousands of snapshots of each virtual volume can be created assuming
that there is sufficient storage space available. For additional information on virtual copies, see
“Virtual Copy Snapshots” (page 46).
NOTE: An HP 3PAR Virtual Copy license is required to create virtual copies. For more information,
see “HP 3PAR Software” (page 9).
Exporting Virtual Volumes
For a host to see a virtual volume, the volume must be exported as a LUN. Volumes are exported
by creating Virtual Volume-LUN pairings (VLUNs) on the system. When you create VLUNs the
system produces both VLUN templates that establish export rules, and active VLUNs that the host
sees as a LUN or attached disk device. For more information about active VLUNs, VLUN templates,
and VLUN template types, see “Exporting Virtual Volumes” (page 48).
HP 3PAR Software
In addition to HP 3PAR Operating System Software, HP offers separately licensed software suites,
optional software features, and a set of host-based software applications. You can use the HP
3PAR Command Line Interface (CLI) Software and the HP 3PAR Management Console Software
to view the licenses currently enabled on your system.
HP 3PAR Software 9

IMPORTANT: Optional HP 3PAR software features may not currently be enabled on your system
because they require additional licenses and may require separate installations. When features
are not available on your system because they are not licensed for use, screens and functionality
relating to those features may appear grayed-out or be otherwise inaccessible in the HP 3PAR
Management Console and HP 3PAR CLI.
To learn about adding optional products and features to enhance your HP 3PAR storage systems,
contact your local service provider.

3PAR thin copy reclamation, see “Enhanced Storage Applications” (page 53).
•HP 3PAR Persistent Ports Software: eliminates the dependency on multipath software during
the process of online software upgrades. Persistent ports enable the host paths to remain online
during the online upgrade process. Persistent ports are also called virtual ports.
•HP 3PAR Persistent Cache Software: allows systems to maintain a high level of performance
and availability during node failure conditions, and during hardware and software upgrades.
This feature allows the host to continue to write data and receive acknowledgments from the
system if the backup node is unavailable. Persistent cache automatically creates multiple
backup nodes for logical disks that have the same owner. Persistent cache also maintains
service levels by preserving write-caching through rapidly re-mirroring the cache to the other
nodes in the cluster in the event of a cache or controller node failure.
•HP 3PAR System Tuner Software: improves performance by identifying overused physical disks
and performing load balancing on those disks without interrupting access. To learn more
about the HP 3PAR System Tuner, see “Enhanced Storage Applications” (page 53).
•HP 3PAR Thin Provisioning Software: allows you to allocate virtual volumes to application
servers yet provision only a fraction of the physical storage behind these volumes. By enabling
a true capacity-on-demand model, a storage administrator can use HP 3PAR Thin Provisioning
to create TPVVs that maximize asset use. To learn more about TPVVs, see “Virtual
Volumes” (page 42).
•HP 3PAR Thin Conversion Software: converts an FTPP to a TPPV. Virtual volumes with large
amounts of allocated but unused space are converted to TPVVs that are much smaller than the
original volume. To use the thin conversion feature, you must have an F-Class, T-Class, HP

2 HP 3PAR Storage System Users
User Accounts
In order to access an HP 3PAR storage system you must have a user account. Each HP 3PAR OS
user is assigned a role, and each role is assigned a set of rights. The roles and rights assigned to
the user determine which tasks the user can perform with a system. Assign roles to users based on
the tasks you intend the users to perform.
Eight roles are defined in the HP 3PAR OS. See Table 2 (page 18) for a description of each role.
There are four standard roles:
•Browse
•Edit
•Super
•Service
There are also four extended roles:
•Create
•Basic Edit
•3PAR AO
•3PAR RM
There is no functional difference between standard and extended roles. The extended roles define
a set of rights optimized for users with specialized or restricted tasks. For example, assigning a
user the Create role allows the user to create virtual volumes and other objects but does not allow
the user to remove virtual volumes. To maintain greater control over your system, assign users roles
with the minimum set of rights they need to perform their tasks. To view a list of roles and all of
the rights assigned to each role, see the HP 3PAR Command Line Interface Administrator’s Manual.
User management tasks can be performed with both the HP 3PAR CLI Software and the HP 3PAR
Management Console Software. Refer to the HP 3PAR Command Line Interface Administrator’s
Manual and the HP 3PAR Management Console Online Help for instructions on how to perform
user management tasks.

Create
Rights are similar to the Edit role. For example, creating
and editing virtual volumes and other objects. The rights

Local User Authentication and Authorization
Users accessing the HP 3PAR storage system with the HP 3PAR CLI client or Secure Shell (SSH)
connections are authenticated and authorized directly on the system. These users are referred to
as local users. The information used to authenticate and authorize a local user is stored on the
system.
For instructions on creating a local user, refer to the HP 3PAR Command Line Interface
Administrator’s Manual and the HP 3PAR Management Console Online Help.
LDAP User Authentication and Authorization
An LDAP user is authenticated and authorized using information from a Lightweight Directory
Access Protocol (LDAP) server. If multiple systems are configured to use the same LDAP server, a
user that can access one system can access all systems with the role and rights assigned to the
LDAP group.
Local user roles and rights are associated with an individual, LDAP user roles and rights are the
same for all members of the group. If you want to authenticate and authorize LDAP users with
different roles, you must create an LDAP group for each role.
For detailed information about LDAP users and LDAP connections, see “Lightweight Directory Access
Protocol” (page 20). For instructions on setting up an LDAP connection, refer to the HP 3PAR
Command Line Interface Administrator’s Manual.
Domain User Access
Adomain user is a user with access to a specific domain. Local users belonging to a system using
HP 3PAR Virtual Domains Software are domain users. In addition to the user’s roles and rights, a
domain users’ activities are also limited to the domains to which they have access. A domain user’s
assigned user role is applicable only within the domain to which the user has access.
For detailed information about virtual domains and domain users, see “HP 3PAR Virtual Domains”
(page 24). For instructions on creating a domain user, refer to the HP 3PAR Command Line Interface
Administrator’s Manual and the HP 3PAR Management Console Online Help.
NOTE: Virtual domains require an HP 3PAR Virtual Domains Software license. For additional
information about the license, see “HP 3PAR Software” (page 9).
Local User Authentication and Authorization 19

3 Lightweight Directory Access Protocol
Overview
The Lightweight Directory Access Protocol (LDAP) is a standard protocol for communication between
LDAP clients and LDAP directory servers. Data is stored as a directory hierarchy by the server and
clients add, modify, search, or remove the data. The data can be organized using standard schemas
understood by clients and servers from different vendors or by an application-specific schema used
only by a particular vendor or application.
The HP 3PAR OS contains an LDAP client that can be configured to use an LDAP server for
authentication and authorization of system users. In an environment where there are multiple systems
configured to use the same LDAP server in the same way, a single user with access to one system
server can access all of the environment’s systems with the same role.
Accessing objects on systems configured to use HP 3PAR Virtual Domains Software requires access
to the domain in which those objects reside. The configuration of domains may differ from one
system installation to the next. This results in differing levels of access over objects based on mapping
between the LDAP configuration and the individual system’s domain configuration.
The HP 3PAR LDAP client is designed to work with various LDAP servers and schemas for data
organization. However, only use with the Active Directory LDAP directory implementation is currently
supported.
Configuring the HP 3PAR OS to use LDAP can only be performed with the HP 3PAR Command
Line Interface (CLI). Refer to the HP 3PAR OS CLI Administrator’s Manual for instructions on how
to perform these tasks.
NOTE:
•At the current time, the OpenLDAP directory implementation is also available, however, on a
limited basis. Check with your local HP service representative for updates on availability.
•All LDAP related tasks are performed with the HP 3PAR Command Line Interface (CLI).
Active Directory
Active Directory is an implementation of LDAP directory services by Microsoft for use in Windows
environments. An Active Directory server is both an LDAP and Kerberos server. When set up for
SASL binding (see “SASL Binding” (page 22)), the Active Directory server and Kerberos server are
used for both authorization and authentication of users.
OpenLDAP
OpenLDAP is an open source implementation of LDAP directory services developed by the OpenLDAP
Project. OpenLDAP includes a server, client library, and tools that are available for a wide variety
of operating systems. Different schemas can be used for user and group information with OpenLDAP.
For example, the Posix schema is typically used for user and group information in Linux/Unix
systems.
LDAP Users
Users created with the HP 3PAR CLI who access the system using HP 3PAR CLI clients, or with SSH,
are authenticated and authorized directly on the system. These users are referred to as local users.
An LDAP user is similar to a local user; however, an LDAP user is authenticated and authorized
using information from an LDAP server.
During authentication, if a user name is not recognized as a local user, that user’s name and
password are checked on the LDAP server. The local user’s authentication data takes precedence
