This is not specifically MAINFRAME question But I ran across this
article that talks about replacing their UPS with a fly wheel system
(please read the article) at >http://searchdatacenter.techtarget.com/
originalContent/0,289142,sid80_gci1288892,00.html?
track=NL-455&ad=619599&asrc=EM_NLN_2844322&uid=6570353<
Watch the wrap above
My problem with this way of doing UPS is that the article states that
they can loose power a full second before the "new" UPS kicks in.
I am *NOT* knowledgeable in UPS's but to me a second is a way too
much time to loose power and any computer (MF or PC) would roll over
and die.
Is my guess correct? I vaguely remember (read LONG time ago) that
power interruptions that last longer that 500MS (microseconds) will
bring most computers down rather quickly. I am *NOT* sure of the
500MS (it may have be less). Can anyone supply a better number?
Or are they saying a (one) second outage is OK as they will have to
reboot and so what?
Thanks,
Ed
