(for example, data replication). Notes: 1. For DS8000, you can have a maximum of 256 clients connected to a single storage unit server at the same time. Clients include all DS Storage Managers, DS command-line interfaces, DS open application interfaces, and IBM TotalStorage Productivity Center for Replication sessions.
Page 41: Ds Open Application Programming Interface
The DS Open API allows these storage management applications to communicate with a storage unit. The DS Open API supports the IBM System Storage DS8000 and the IBM System Storage DS6000 series, and the IBM TotalStorage Enterprise Storage Server. It is available for the AIX, Linux, and Windows operating system environments and must be used on storage units that have fibre-channel ports.

The DS8000 models offer a high degree of availability and performance through the use of redundant components that can be replaced while the system is operating. You can use the DS8000 models with a mix of different operating systems and clustered and nonclustered variants of the same operating systems.
Page 44: Host Attachment Overview
The IBM System Storage DS8000 series supports SAN connections of up to 2 Gbps with 2 Gb host adapters, and up to 4 Gbps with 4 Gb host adapters. The DS8000 series negotiates automatically and determines whether it is best to run at a 1 Gbps, 2 Gbps, or 4 Gbps link speed.

7 days a week. This set of products provides disaster recovery, data migration, and data duplication functions. As a part of the IBM System Storage Resiliency Family, the DS8000 series supports Copy Service functions that contribute to the protection of your data. These functions are also supported on the IBM TotalStorage Enterprise Storage Server.
Page 52 IBM System Storage Metro Mirror (previously known as Synchronous PPRC) Metro Mirror provides real-time mirroring of logical volumes between two DS8000 storage units that can be located up to 300 km from each other. It is a synchronous copy solution where write operations are completed on both copies (local and remote site) before they are considered to be done.
Page 53 Ensures that write operations are inhibited on the target volume until a refresh FlashCopy operation is complete. Multiple Relationship FlashCopy Allows a source volume to have multiple (up to 12) target volumes at the same time. Chapter 1. Introduction to IBM System Storage DS8000 series...
Page 54 Remote mirror and copy is an optional feature that provides data backup and disaster recovery. To use it, you must purchase at least one of the remote mirror and copy 2244/239x function authorization features. DS8000 storage units can participate in remote mirror and copy solutions with the DS6000 series, ESS Model 750, and ESS Model 800.

(The domain of an I/O operation is the specified extents to which the I/O operation applies.) You can enhance PAV by adding the IBM HyperPAV feature which allows you to use alias addresses to access any base on the same control unit image per I/O base.
Page 59: Ds8000 Series Limitations
Volume creation and volume expansion is limited to 3390 Model 9 sizes if earlier software has a path group on the DS8000. Volumes larger than 3390 Model 9 do not come online if earlier z/OS software is in use.
Page 60: Planning Data Migration
Planning data migration The planning and methods of data migration for the DS8000 vary by environment. The DS8000 supports over 90 operating systems. You can migrate data to a storage unit from these host and operating system environments. When you plan for data migration, consider the following factors: Note: The following lists do not cover every possibility.

Because the System i host does not support 7133 drawers, you have no existing 7133 drawers to reformat. If you have an existing disk subsystem that you are replacing with a DS8000, you must migrate the data to the DS8000. Use your existing host utilities for the data migration.

Migrating data to a DS8000 storage unit using volume management methods The UNIX volume manager method for migrating data is very similar to the method that is used by AIX systems. It involves the use of commands or a combination of commands that copy and move the data.

Page 184: Returning Production To Local Site After Planned Outages
After restoring operations at Site B, you can schedule a failback operation to synchronize data and to enable production to resume at your original site, Site A. Before you run a failback operation, you must create paths from Site B to Site A between the specific LSSs. DS8000 User’s Guide...
Page 185 For this scenario, assume that Site A is operational and that connectivity from Site B to Site A is available. Use this procedure to restart your production environment using the volumes from Site B. After the failover operation processes, the volumes at Site B are available to be mounted and used by a host.
