CPW Help!!

[Guest.Visitor]

The total CPW is the for one total processor. You then divide the processor up along the LPARS. The same CPU division formula applies to the CPW. Example: Our 520 has 2800 CPW total for our processor. (We can use .75 of the processor). One LPAR has .35, one has .30 and one has .10. That means LPAR 1 has 2800 * .35 = 980 CWP, LPAR 2 is 840 and LPAR 3 has 280.

CPW Help!!

Scott: Many thanks for your prompt response. However, is there a reason why you can only use 75%? Is this across the board, or does the 75% only applies to your box? Cheers,

CPW Help!!

We can only user 75% because of the total CPW that we licensed, and some machine background stuff uses some of the CPW too. Not sure how much for that though. (No, the governor is NOT gone!)

CPW Help!!

We have a 570 shop with multiple LPars. Can anyone tell me whether the CPW is divided among the LPars, and how can I determine how much is allocated to each. Thank you.

CPW Help!!

Your model 570 will have more than 1 CPU, and each CPU is counted as 1.00... you allocate a minimum of 0.1 per LPAR, adding increments of 0.01 to increase this. As a very simple example, suppose you have an 8-way 570 with 6 LPARs. You could have 1 LPAR with, say 4.0 processors, another at, say 1.2, and the others at '0.something'. Manage/view this lot, you need access to the HMC (Hardware Management Console), which is used to configure and manage the LPARs. Your administrator can grant you remote access to the HMC if our security policy allows it. In the case of the chap with the 2800 CPW processor, the 520 range starts at 1200 CPW, which is really about 0.32 of a Power5+ processor (so it has about 0.32 to allocate or similar)...Full processor in 520 range = 3800 (that model would have 1.00 available to allocate). So, you see, IBM have already LPAR'd some of the 520 range!!!
