Ordering z/OS and related products
You can order products and maintenance for the z/OS platform on the Web. ShopzSeries provides a self-service planning and ordering capability on the Web. You can order system/product upgrades for either ServerPac or CBPDO. ShopzSeries includes the following significant functions:
ShopzSeries support for maintenance includes ordering corrective service by PTFs or APARs and Recommended Service Upgrade (RSU) preventive service. In addition, service orders can be received on traditional media or the Internet. For an RSU order, you can upload your SMP/E CSI installed service inventory, which is used to customize your order and eliminate duplicate service.
IBM has delivered z/OS platform products on DVD starting September 10, 2010. This expands the delivery options available to include Internet, DVD, 3590, and 3592 tape. Installation from DVD will require network connectivity between your z/OS system and a workstation having a DVD drive. Product delivery on all 3480 and 3490 tape media was discontinued October 26, 2010. For more information see the July 22, 2010 IBM United States Software Announcement letter (210-235).

Performance information and storage requirement
Over several z/OS releases, we have provided system-level performance improvements, and V2.1 continues the trend. Performance tests show up to a 2% CPU reduction when migrating from z/OS V1.13 to V2.1. At z/OS V2R1 GA, the zSoftCap tool provides more specific capacity planning information for the migration to z/OS V2R1.
The minimum amount of real storage required to IPL z/OS depends on a number of factors, including the number of devices in the I/O configuration, the amount of storage configured, the number of address spaces created, the types of applications supported, and the products and subsystems supported in the IPLed system. In IPL studies at IBM, 256 MB of real storage was the minimum amount required to IPL z/OS V1R13 and z/OS V2R1. The systems in the studies were IPLed to the point of completing JES2 initialization. The systems had I/O configurations defined with the following devices:
- 51168 direct access devices (DASDs)
- 16 graphics devices
- 5127 channel-to-channel (CTC) connections
- 52 tape drives
