3.6 POWER Version 2.2 enhancements
The latest available PowerVM Version 2.2 contains the following enhancements:
򐂰 Up to 20 logical partitions per core
򐂰 Role Based Access Control (RBAC)
RBAC brings an added level of security and flexibility in the administration of Virtual I/O
Server. With RBAC, you can create a set of authorizations for the user management
commands. You can assign these authorizations to a
UserManagement
role, and this role
can be given to any other user. So a normal user with the UserManagement role can
manage the users on the system but will not have any further access.
With RBAC, the Virtual I/O Server can split management functions that presently can be
done only by the
padmin
user, provide better security by providing only the necessary
access to users, and easy management and auditing of system functions.
򐂰 Support for concurrent adding of VLANs
򐂰 Support for USB tape
The Virtual I/O Server now supports a USB DAT-320 Tape Drive and its use as a virtual
tape device for Virtual I/O Server clients.
򐂰 Support for USB Blu-ray
The Virtual I/O Server (VIOS) now supports USB Blu-ray optical devices. AIX does not
support mapping these as virtual optical devices to clients. However, you can import the
disk in to the virtual optical media library and map the created file to the client as a virtual
DVD drive.
The IBM PowerVM IBM Workload Partitions Manager™ for AIX, Version 2.2 has the following
enhancements:
򐂰 When used with AIX 6.1 Technology Level 6, the following support applies:
– Support for exporting VIOS SCSI disk into a WPAR. Compatibility analysis and mobility
of WPARs with VIOS SCSI disk. In addition to Fibre Channel devices, now VIOS SCSI
disks can be exported into a workload partition (WPAR).
– WPAR Manager command-line interface (CLI). The WPAR Manager CLI allows
federated management of WPARs across multiple systems by command line.
– Support for workload partition definitions. The WPAR definitions can be preserved after
WPARs are deleted. These definitions can be deployed at a later time to any
WPAR-capable system.
򐂰
In addition to the feature supported on AIX 6.1 Technology Level 6, the following support
applies to AIX 7.1:
– Support for AIX 5.2 Workload Partitions for AIX 7.1. Lifecycle management and
mobility enablement for AIX 5.2 Technology Level 10 SP8 Version WPARs.
– Support for trusted kernel extension loading and configuration from WPARs. Enables
exporting a list of kernel extensions that can then be loaded inside a WPAR, yet
maintaining isolation.
