Table H-1 gives the minimum support requirements for Flash Express.
Table H-1 Minimum support requirements for Flash Express
You can use the Flash Express allocation windows on the SE or Hardware Management
Console (HMC) to define the initial and maximum amount of Flash Express available to an
LPAR. The maximum memory that is allocated to an LPAR can be dynamically changed. On
z/OS, this process can also be done by using an operator command. Flash memory can also
be configured offline to an LPAR.
Figure H-4 gives a sample SE/HMC interface that is used for Flash Express allocation.

The SE user interface for Flash Express provides the following types of actions:
򐂰 Flash status and control: Displays the list of adapters that are installed in the system and
their state.
򐂰
Manage Flash allocation: Displays the amount of flash memory on the system.
򐂰 View Flash allocations: Displays a table of flash information for one partition.
򐂰
View Flash: Displays information for one pair of flash adapters.
Physical Flash Express PCIe cards are fully virtualized across LPARs. Each LPAR can be
configured with its own storage-class memory (SCM) address space. The size of Flash
Express memory that is allocated to a partition is done by amount, not by card size. The
hardware supports error isolation, transparent mirroring, centralized diagnostic procedures,
hardware logging, and recovery, independently from the software.
