Tips on VIrtualization and Micropartitioning

1. What are the different types of installation of VIO server ?

a. Installation from CD
b. NIM Based installation

2. What is the maximum # of virtual processor per partition (lpar) ?

64 Virtual Processors

3. What is the maximum # of logical processor supported by AIX Operating System ?

128 Logical Processors

4. What are the different types of processor sharing modes ?

Capped or Uncapped modes

5. What are the different types of I/O virtualization that can be implemented in a p5 server ?

a. Virtual Ethernet
b. Shared Ethernet Adapters
c. Shared Fibre Channel Adapters
d. Virtual Disks

6. What is the range for variable capacity weight ?

0 to 255 is the range for the variable capacity weight.
128 is the default weight for uncapped partitions.
Weight 0 is equivalent to capped mode.

7. What is the LMB for Power 4 and Power 5 machines ?

Power 4 - 256 MB Logical Memory Block
Power 5 - 16 MB LMB

LMB is the minimum memory block that can allocatable to an LPAR.

8. What is the minimum allocatable processing unit for an lpar ?

Initial assignment is a minimum of 0.10 (1/10th) processing unit.
Increments can be made at a minimum of 0.01 (1/100th) proccessing unit.

9. How can we calculate hypervisor overhead for an lpar ?

It can be calculated by dividing the maximum memory setting by 64 and rounding up to the nearest logical memory block size.

10. TIP :

You can have maximum of 256 VIO slots per partition

11. TIP :

In VIO Server, you can have maximum of 65535 virtual I/O slots

12. TIP :

You can have maximum of 256 Virtual Ethernet Adapters per partition

13. TIP :

You can have 254 partitions or 10 * # processors per power machine
