In September 2021 IBM introduced the new E1080 server which uses our next generation for IBM Power processor, Power10. The E1080 is designed to scale core operational workloads and AI applications securely and efficiently across hybrid cloud.
See Key Features of Power10 for an overview of many of the new hardware features. In addition of Power10 hardware improvements, updates have also been made to the PowerVM components such as VIOS, HMC and Server firmware.
The following enhancements and new features are available in VIOS 3.1.3:
The following enhancements and new features are available in HMC Version 10 Release 1 Maintenance 1010:
In previous versions of PowerVM, if an optical device was assigned to a logical partition, the customer needed to remove the device from the partition prior to performing LPM or Remote Restart. Starting with VIOS 3.1.3 and HMC V10 R1 M1010, if there is no media loaded in the optical device, the LPM or Remote Restart operation will be allowed and a new optical device will be created for the partition on the destination server.
Automatic selection of network device in Mover/Server partition
In previous versions when an LPM operation was performed and the request did not explicitly specify a network device that should be used by the Mover/Server partition, PowerVM would just select a device that could transmit the data. With the latest version of PowerVM starting with VIOS 3.1.3 and HMC V10 R1 M1010, the device selection is based on the performance characteristics of the device.
When mapping from logical memory address to physical real addresses in a virtualized environment, there is a structure that is used by the OS, firmware and hardware that provides this mapping. This structure is referred to as the hardware page table (HPT). Linux on Power was originally designed on other platforms where the HPT was organized in a radix tree format. Power System’s support a hashed organization of this hardware page table so the Linux kernel when running on Power system added hashed page table support. Starting with Power10, the hardware was enhanced to support both a radix and the existing hashed page tables. Changes have been made in newer versions of Linux to support the radix page table architecture on Power10.
AIX Update Access Keys (UAK)
When a customer buys a software product like AIX, frequently they purchase a software maintenance agreement (SWMA) that allows customers to contact support for problems, install fixes and install new versions of the product. Enhancement have been made in PowerVM and AIX to report the expiration date of this agreement for a given server. This helps to ensure that if the need exists to install new features for AIX or contact support, that there is an agreement in place for support. More information on this enhancement can be found at AIX Update Access Keys.
At the introduction of new version of PowerVM, IBM reviews the currently offered features and determines the adoption of these features by our customers. Call Home data, user groups and other methods are used to determine the usage of these features. Because of the low adoption and ongoing testing/development needed to continue to maintain the following features, IBM has decided to drop support for these features in Power10. HMC, since it can manage previous generation of systems and VIOS ,since they run on older hardware models, still have support for these features on supported systems.
