Kindly answer the following questions regarding AIX:

Does AiX can support upto 12 simultaneous thread per core? yes or no
Does Aix is binary compatible with Solaris Applications? yes or no
Does AIX affects only that partition? yes or no
Does AIX can run 16 partitions per processor? yes or no
When partitioning 4-core p 570 into three physical LPARs. Customer wants to run AIX V5.2. What additional information needs to be relayed to the customer?

• to order powervm to provide VIOS
• Dedicated boot device for each LPAR
• Must upgrade to 5.3 for three partitions

Hi... You asked:

Does AiX can support upto 12 simultaneous thread per core? yes or no. No. Power5 & 6 servers support 2 threads per Core.

Does Aix is binary compatible with Solaris Applications? yes or no. No.

Does AIX affects only that partition? yes or no. Don't understand the question.

Does AIX can run 16 partitions per processor? yes or no. Maybe. The maximum number of Logical partitions is 10 per core. The maximum number of Workload Partitions per core is unlimted (as far as I know).

When partitioning 4-core p 570 into three physical LPARs. Customer wants to run AIX V5.2. What additional information needs to be relayed to the customer?

+ to order powervm to provide VIOS - optional. For just 3 LPARs, I would recommend against VIOS.
+ Dedicated boot device for each LPAR - yes and no. Yes you can use dedicated boot device either on the SAN or locally attached, but you can also use a NIM server to do network boot where each LPAR is booting from a common boot strap.
+ Must upgrade to 5.3 for three partitions - No. Each LPAR's OS level is independent of each other. on a 4-core p570 you can have a mix of AIX 5.2 and 5.3 LPARs.

Hope that helps...

One word of caution.. Your questions about threads makes me think you are comparing POWER hardware to Sun's Niagara or Victoria Falls servers. Although the Niagara/VF servers do have more threads, the POWER6 520 and/or 550 compete head to head with them. The POWER6's superior clock speed and single thread performance overcomes the multi-threading capability of Niagara/VF servers for most workloads...

First of all thank you for your anticipation. Hey the line which you didnt understood was:

AIX failures effect the partition in which it resides? yes or no

Few more questions whihc i will be requiring your support:

Q1. Sun offers CPU deallocation just like IBM. Which of the following refutes this claim?

a) Sun uses hot swap to perform CPU deallocation.

b) After a CPU failure, the Sun partition must reboot.

c) Sun requires unallocated processors to perform deallocation.

d) During a CPU failure, the Sun application is suspended while the processor is replaced.

Q2. Which IBM branded software offering allows for Power Systems failover in a WAN?
a) HACMP

b) HACMP-XD

c) Veritas Cluster Server

d) HACMP Disaster Recovery

Thank you

Are you going to pay us for helping you pass this exam?

Or for producing this customer spec?

Or whatever it is you've got us doing for you?

Or do I just think too cynically about the format of your questions.

Your welcome... glad it helps... so to address your following questions...
AIX failures effect the partition in which it resides? yes or no . Yes, an AIX failure ONLY affects the Logical partition where the failure occur. The other LPARs continue to run completely unaware of an AIX fault.

c) Sun requires unallocated processors to perform deallocation.

d) During a CPU failure, the Sun application is suspended while the processor is replaced.

I do not know how Sun's CPU deallocation works. The way that POWER Systems works is the hardware is constantly monitoring the hardware and if a processor (i.e. core) crosses the threshold of errors, the Server is dyanmically remove this processor core from service. The executing LPARs will continue to operate; you do not need to reboot. The applications continue to work adn are not suspended. The actual hardware replacement is deferred until a later time when the server can be brought down.

Does that help?
Q2. Which IBM branded software offering allows for Power Systems failover in a WAN?

a) HACMP

b) HACMP-XD

c) Veritas Cluster Server

d) HACMP Disaster Recovery

IBM's WAN Failover software is HACMP-XD. Veritas Cluster Server probably can do this as well, but that is branded by Symantec, not IBM.

Thanks,
