Terminology used in this document
Provides a list of terms used in this document.
TS7650G or Gateway
These are terms for IBM's virtualization solution from the TS7650 family
that does not include a disk storage repository, allowing the customer to
choose from a variety of storage options. IBM does support two clustered
pairs of TS7650 Gateway servers in a single frame. The TS7650G consists of
the following:
Server There are three types of server that have been used in the
Gateway:
3958 DD4
This is a newer, higher performance server available in
December 2010. This server is based on the IBM System
x3850 X5 Type 7145-AC1. When used as a server in the
TS7650G, its machine type and model are 3958 DD4. Use
this machine type and model for service purposes.
3958 DD3
This is a higher performance server available in March
2009. This server is based on the IBM System x3850 M2
Type 7233. When used as a server in the TS7650G, its
machine type and model are 3958 DD3. Use this machine
type and model for service purposes.
3958 DD1
This is the original server available in August 2008. This
server is based on the IBM System x3850 M2 Type 7141.
When used as a server in the TS7650G, its machine type
and model are 3958 DD1. Use this machine type and
model for service purposes.
System console
The system console is a TS3000 System Console (TSSC). This
document uses the terms system console and TSSC interchangeably.
Under IBM best practices, the TS7650G also contains the following:
Disk controller
The customer must choose the disk controller for use with the
TS7650G. A list of compatible controllers is located at the IBM Tape
Systems Resource Library website: http://www-03.ibm.com/
systems/storage/tape/library.html#compatibility in the
TS7650/TS7650G ISV and interoperability matrix document.
Disk expansion unit
The customer must choose the disk expansion unit for use with the
TS7650G. A list of compatible expansion units is located at the IBM
Tape Systems Resource Library website: http://www-03.ibm.com/
2IBM System Storage TS7600 with ProtecTIER: Software Upgrade Guide

systems/storage/tape/library.html#compatibility in the
TS7650/TS7650G ISV and interoperability matrix document.
TS7650
When used alone, this term signifies IBM's family of virtualization
solutions that operate on the ProtecTIER platform.
TS7650 Appliance or appliance
These are terms for IBM's self-contained virtualization solution from the
TS7650 family that includes a disk storage repository. The TS7650
Appliance consists of the following:
Server The 3958 AP1 server is based on the IBM System x3850 X5 Type
7145-AC1 at the ProtecTIER version 3.1 release. When used as a
server in the TS7650 Appliance, its machine type and model are
3958 AP1. Use this machine type and model for service purposes.
System console
The system console is a TS3000 System Console (TSSC). This
document uses the terms system console and TSSC interchangeably.
Disk controller
The disk controller for the TS7650 Appliance is an IBM Feature
Code 3708: 4.8 TB Fibre Channel Disk Controller. Use this feature
code for service purposes.
Disk expansion unit
The disk expansion unit for the TS7650 Appliance is an IBM
Feature Code 3707: 4.8 TB Fibre Channel Disk Expansion Unit. Use
this feature code for service purposes.
OpenStorage
OpenStorage allows ProtecTIER to be integrated with NetBackup to
provide the means for backup-to-disk without using a virtual tape library
(VTL) emulation. Using a plug-in that is installed on an
OpenStorage-enabled media server, ProtecTIER can implement a
communication protocol that supports data transfer and control between
the backup server and the ProtecTIER server. Therefore, to support the
plug-in, ProtecTIER implements a storage server emulation.
replication
A process that transfers logical objects like cartridges from one ProtecTIER
repository to another. The replication function allows ProtecTIER
deployment to be distributed across sites. Each site has a single or
clustered ProtecTIER environment. Each ProtecTIER environment has at
least one ProtecTIER server. The ProtecTIER server that is a part of the
replication grid has two dedicated replication ports that are used for
replication. Replication ports are connected to the customer's WAN and are
configured on two subnets as default.
replication grid
A set of repositories that share a common ID and can potentially transmit
and receive logical objects through replication. A replication grid defines a
set of ProtecTIER repositories and actions between them and is configured
using the ProtecTIER Replication Manager. The ProtecTIER Replication
Manager is a software component that is installed on a ProtecTIER server
or a dedicated host. The ProtecTIER Replication Manager should be able to
recognize all the members of the entire network the ProtecTIER Replication
Manager handles on both replication subnets. The ProtecTIER Replication
Manager is deployed separately from the ProtecTIER Manager on the
Chapter 1. Upgrading the TS7650 Appliance or TS7650G (Gateway) to ProtecTIER V3.1.x.x 3

customer's ProtecTIER server. The ProtecTIER Replication Manager
manages the configuration of multiple replication grids in an organization.
An agent on every node in each ProtecTIER server interacts with the server
and maintains a table of its grid members.
replication grid ID
A number from 0 to 63 that identifies a replication grid within an
organization.
replication grid member
A repository that is a member in a replication grid.
replication pairs
Two repositories within a replication grid that replicate from one to
another.
replication policy
A policy made up of rules that define a set of objects (for example, VTL
cartridges) from a source repository to be replicated to a target repository.
repository unique ID (RID)
A number that uniquely identifies the repository. The RID is created from
the replication grid ID and the repository internal ID in the grid.
replication timeframe
A scheduled period of time for replication to take place for all policies.
shelf A container of VTL cartridges within a ProtecTIER repository.
virtual tape library (VTL)
The ProtecTIER virtual tape library (VTL) service emulates traditional tape
libraries. By emulating tape libraries, ProtecTIER VTL enables you to
transition to disk backup without having to replace your entire backup
environment. Your existing backup application can access virtual robots to
move virtual cartridges between virtual slots and drives. The backup
application perceives that the data is being stored on cartridges while
ProtecTIER actually stores data on a deduplicated disk repository.
visibility switching
The automated process that transfers the visibility of a VTL cartridge from
its master to its replica and vice versa. The visibility switching process is
triggered by moving a cartridge to the source library Import/Export (I/E)
slot. The cartridge will then disappear from the I/E slot and appear at the
destination library's I/E slot. To move the cartridge back to the source
library, the cartridge must be ejected to the shelf from the destination
library. The cartridge will then disappear from the destination library and
reappear at the source I/E slot.
server and node
This document uses the terms server and node, interchangeably.
destination and target
This document uses the terms destination and target, interchangeably.
