a method for key identifi cation, exchange, separation,
update, backup, and management. The TKE worksta-
tion and 4.0 code level are designed to provide a secure,
remote, and fl exible method of providing Master Key Entry
and to remotely manage PCIX Cryptographic Coprocessors.

z990 Capacity Upgrade on Demand (CUoD)
Capacity Upgrade on Demand allows for the nondisruptive
addition of one or more Central Processors (CPs), Inter-
nal Coupling Facilities (ICFs), Integrated Facility for Linux
(IFLs), and IBM ^ zSeries Application Assist Pro-
cessor (zAAP). Capacity Upgrade on Demand can quickly
add processors up to the maximum number of available
inactive engines. This provides customers with the capac-
ity for much needed dynamic growth in an unpredictable
e-business world. The Capacity Upgrade on Demand
functions, combined with Parallel Sysplex technology, can
enable virtually unlimited capacity upgrade capability.
The CUoD functions are:
• Nondisruptive CP, ICF, IFL, and zAAP upgrades within
minutes
• Dynamic upgrade of all I/O cards in the I/O Cage
• Dynamic upgrade of spare installed memory
Plan Ahead and Concurrent Conditioning
Concurrent Conditioning confi gures a system for hot
plugging of I/O based on a future specifi ed target con-
fi guration. Concurrent Conditioning of the zSeries I/O is
minimized by the fact that all I/O cards plugging into the
zSeries I/O cage are hot pluggable. This means that the
only I/O to be conditioned is the I/O cage itself. The ques-
tion of whether or not to concurrently condition a cage is
a very important consideration, especially with the rapid
change in the IT environment (e-business) as well as the
technology. Migration to FICON Express or additional
OSA-Express networking is exceptionally easy and non-
disruptive with the appropriate microcode load and if the
cage space is available.
