Who should read this guide This guide is intended for anyone who is registered as an administrator for IBM Spectrum Protect. A single administrator can manage IBM Spectrum Protect, or several people can share administrative responsibilities. You should be familiar with the operating system on which the server resides and the communication protocols required for the client or server environment. You also need to understand the storage management practices of your organization, such as how you are currently backing up workstation files and how you are using storage devices. Publications The IBM Spectrum Protect product family includes IBM Spectrum Protect Snapshot, IBM Spectrum Protect for Space Management, IBM Spectrum Protect for Databases, and several other storage management products from IBM®.

Planning for a tape-based data protection solution Plan for a data protection implementation that includes disk-to-disk-to-tape backup and disk staging to optimize storage. Offsite options include sending data to another location, or copying data to a remote library. Planning roadmap Plan for the tape solution by reviewing the architecture layout in Figure 1 and then completing the roadmap tasks that follow the diagram. Tape Applications, virtual machines, systems Ideal for long-term retention Low-cost scalability Disk staging to primary tape pool Optimized for SAN Offsite options Server Second copy sent offsite Inventory Staging pool on disk for storage pool backup Or Primary pool on tape for storage pool and inventory backup Remote library for offsite copy Figure 1. Tape solution In this data protection configuration, the server uses both disk and tape storage hardware. Storage pool staging is used, in which client data is initially stored in disk storage pools and then later migrated to tape storage pools. To plan for a tape-based solution, complete the following tasks: 1. Select a system size. 2. Meet system requirements for hardware and software. 3. Record values for your system configuration in the planning worksheets. 4. Plan for disk storage. 5. Plan for tape storage. 6. Plan for security. © Copyright IBM Corp. 1993, 2017 1 2 IBM Spectrum Protect: Tape Solution Guide Chapter 1. Selecting a system size Select the size of the IBM Spectrum Protect server based on the amount of data that you manage and the systems to be protected. About this task You can use the information in the table to determine the size of the server that is required, based on the amount of data that you manage. The following table describes the volume of data that a server manages. This amount includes all versions. The daily amount of data is how much new data you back up each day. Both the total managed data and daily amount of new data are measured as the size before any data reduction. Table 1. Determining the size of the server Total managed data Daily amount of new data to back up Required server size 48 TB - 192 TB Up to 10 TB per day Small 200 TB - 800 TB 10 - 20 TB per day Medium 1000 TB - 4000 TB 20 - 100 TB per day Large The daily backup values in the table are based on test results with 128 MB sized objects, which are used by IBM Spectrum Protect for Virtual Environments. Workloads that consist of objects that are smaller than 128 KB might not be able to achieve these daily limits. © Copyright IBM Corp. 1993, 2017 3 4 IBM Spectrum Protect: Tape Solution Guide Chapter 2. System requirements for a tape-based solution After you select the IBM Spectrum Protect solution that best fits your data protection requirements, review the system requirements to plan for implementation of the data protection solution. Ensure that your system meets the hardware and software prerequisites for the size of server that you plan to use. Hardware requirements Hardware requirements for your IBM Spectrum Protect solution are based on system size. Choose equivalent or better components than those items that are listed to ensure optimum performance for your environment. For information about planning disk devices, see Planning for disk storage. For information about planning tape devices, see Planning for tape storage. For a definition of system sizes, see Chapter 1, “Selecting a system size,” on page 3. The following table includes minimum hardware requirements for the server and storage, based on the size of the server that you plan to build. If you are using local partitions (LPARs) or work partitions (WPARs), adjust the network requirements to take account of the partition sizes.
