I am replying late in the game but my understanding regarding IFLs is as follows:
You can have as many IFLs on a CEC as there are PUs available to support them. You can mix zIIPs, zAAPs, IFLs, and CPs in an LPAR. IFLs always run at full capacity based on the CEC model, e.g. zEC12 = 1511 MIPS, z196 = 1200, z114/z01 = 782. CPs run at the purchased capacity, e.g. z196/401 =240 MIPS, 501= 586, 601= 765, and a 701= 1200 MIPS. All CPs on a CEC run at the same hardware purchased capacity. You can purchase an MES to change the capacity (up or down). You can soft cap your hardware capacity within z/OS to reduce MLC based on the 4-hour rolling monthly average. You are entitled to purchase 1 zIIP and 1 zAAP for each CP owned; as with IFLs, zIIPs and zAAPs run at full CEC capacity. Linux will run on either an IFL or a CP in native mode, or as a guest under z/VM (which will run on a CP or IFL). Anything (z/OS, z/TPF, z/VSE, Linux, z/VM) will run on a CP. There are IFL-only CECs. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
