The significant improvement introduced in the power five server in terms of virtualisation was the ability to make changes to an LPAR without requiring downtime.

9. What challenges did users face when working with the Power Four server regarding making changes to an LPAR?

Users faced the challenge of requiring downtime to change an LPAR when working with the Power Four server.

10. Propose a solution to the challenge of requiring downtime to change an LPAR in a Power Four server.

One solution to the challenge of requiring downtime for making changes to an LPAR in a power four server is to upgrade to a power five server, which allows for making changes to an LPAR without downtime.

11. What feature of Power Six allows users to move an LPR live from one physical machine to another?

Live Partition Mobility (LTM).

12. Explain how Live Partition Mobility can be helpful during maintenance work on Power Six machines.

Live partition mobility allows users to move an LPR live from one machine to another, enabling them to switch between devices during maintenance work, such as upgrading RAM, changing CPUs, or repairing motherboards.

13. Why did many people switch from Power Five to Power Seven instead of adopting new hardware immediately after the introduction of Power Six?

Many people switched from power five to power seven because it takes time for companies to adopt new hardware, which can take one year or longer.

14. What is a power-efficient model to replace the Power Six with improved performance and reduced power consumption?

A power seven model with improved performance and a 50% reduction in power consumption compared to power six.

15. Why did IBM introduce Power Six servers with unique features for each model?

IBM introduced power six servers with unique features for each model to carry the legacy of power five machines and maintain their popularity.

16. Compare the Power Seven servers with the Power Six servers regarding performance.

The power seven servers have a smaller disk size and are more compact than other models, allowing for more compact storage and performance.

17. Explain why the Blade Server is an economical solution for organisations.

The blade server is an economical solution for organisations because it consumes less power and offers better performance than purchasing giant machines to increase power consumption in a data centre.

18. What does IBM offer the three distinct hardware models?

The three distinct hardware models IBM offers are the IBM X series, IBM PCs, and IBM Z Series.

19. What is the purpose of an operating system?

The purpose of an operating system is to act as a bridge between the user and the hardware, allowing the user to communicate with the hardware using human readable formats.

20. Compare and contrast AIX and Solaris operating systems.

AIX and Solaris are both operating systems used for enterprise business computing.

AIX is known for its robustness and low resource consumption, while Solaris is not mentioned in the context but could potentially have its strengths and weaknesses.

21. What are the advantages and limitations of IBM’s virtualisation technique?

The advantages of IBM’s virtualisation technique include reduced costs, improved resource utilisation, and the ability to share resources between virtual machines.

The limitations include the need for a separate license for each device and limitations in code generation that require a minimum processor and memory requirement.

23. What is a virtual machine migration that minimises downtime and maximises resource utilisation?

A virtual machine migration considers load balancing, resource availability, and network connectivity between machines, prioritise migrating virtual machines during low usage periods to minimise user impact.

Use live migration techniques and monitor resource usage to ensure optimal resource utilisation during the migration process.

24.What is the name of the seventh-generation hardware introduced by IBM?

The seventh generation hardware introduced by IBM is called power seven generation.

25. Explain the concept of AMS Active Memory Sharing Pools and its benefits for memory usage.

AMS active memory sharing pools provide more options for efficiently using memory resources by allowing access to free memory beyond the entitled capacity, ensuring good performance and business continuity.

26. What are the main differences between the Power Six and Power Nine generations regarding hardware offerings and system security features?

The main differences between the power six and power nine generations include the availability of 10 Gigabit Ethernet adapters and a Giga Fibre Channel interface in the power nine generation, as well as advanced system security features such as auditing levels and error reporting mechanisms.

27. What is virtualisation for a hypothetical organisation to improve resource management and reduce operational costs?

Virtualisation for an organisation can include infrastructure analysis, identification of virtualisation opportunities, resource allocation and mapping, implementation of virtualisation technology and tools, regular performance monitoring and optimisation, and training for IT staff on virtualisation best practices.

28. What are some tasks involved in administering an operating system in AIX?
