򐂰 Do not share LUNs with other applications or systems. Use zoning and LUN masking to
isolate the TS7650G from other systems.
򐂰 Avoid using SATA disks for metadata. Fibre Channel or SAS disks (15 K rpm) are wanted
and result in improved performance.
The general concept of a back-end disk storage configuration is described in IBM System
Storage TS7600 with ProtecTIER Version 3.1, SG24-7968. The best practices of how to get
the maximum performance from your ProtecTIER product with the existing disk storage
subsystem are described in Part 2, “Back-end storage subsystems” on page 101.
1.3 ProtecTIER models for open systems
In this section, we provide an overview of the existing models of ProtecTIER servers on the
market. We do not go in to all the technical details. For more technical details and
comprehensive information about each model, see IBM System Storage TS7600 with

1.3.1 ProtecTIER appliances
The IBM System Storage TS7600 ProtecTIER Appliances are delivered to clients with
already attached and pre-configured disk storage subsystems with a specific capacity.
IBM System Storage TS7620 ProtecTIER Deduplication Appliance
Express
Available in two configuration options, the IBM System Storage TS7620 ProtecTIER
Deduplication Appliance Express (model 3959-SM2) is an integrated server and storage
hardware platform that ships with IBM ProtecTIER deduplication software preinstalled. With
an available repository capacity 5.4 or 11 TB, the appliance is targeted at small or medium
business backup environments. Clients can choose between VTL configuration, OST, or the
newly available File System Interface (FSI), which supports Common Internet File System
(CIFS) as a backup target.
The ProtecTIER Deduplication Appliance Express is shown in Figure 1-2.
