  1. p690 issues

    Hi.

    P690 is a IBM server, as we know. This is a power 4 system. On its own,
    its just a P690. However, we can do additional stuff like

    1) adding lpars to it
    2) together with other p690s, we can have HACMP, hardware clustering on
    it

    ?

    I don't see the question. If I'm supposed to grade your
    test, you didn't make any mistakes so you passed.

    Okay.. let me try again.

    what i meant is that p690 on its own is a IBM power 4 server. However,
    we could tap on the features such as lpar, hardware clustering with
    more of the p690s if we have more p690s?

    You can LPAR without any more p690s; LPARs divide the resources of a
    single machine into multiple images. It doesn't combine resources from
    multiple machines.

    You can run HACMP with multiple p690s if you wish.

    And, for future reference, HACMP doesn't require a specific Power
    processor.

    If you want to work on LPARs you need to work within the
    same physical box. Adding more P690 boxes does not mean
    you can add hardware from one box to an LPAR on another.
    The biggest LPAR you can have is one entire box.

    Software clustering with HACMP does not care about the
    hardware. "Hardware clustering" isn't to be confused
    with LPARs. HACMP works among booted hosts no matter
    what box they are in. "Hardware clustered" hosts within
    the same box just have better channels to HACMP
    communication to happen on than "software clustered"
    hosts that use ntwork heartbeats.

    Just to clarify a point that I think has caused confusion. In English,
    "we can" and "we could" are declarative phrases, stating that "we" have
    the ability to do something. "Can we" and "Could we" are interrogative
    phrases, asking if we have an ability.

    I don't want to be Mr. Mean-Grammar-Pants, but it seemed important for
    future reference.

    Hi Nick.

    Its my pleasure to improve my English. Howver, i still dont quite get
    from your previous lesson. Could you drop me a private email ?
    Alternatively, i dont mind if u teach from here.

    Thanks!
