RE: Mirroring Systems

Bruce,

Thanks for the input. Twenty minutes to swap a system sounds good. Does it
matter how many libraries/files you're dealing with?

And what is 5761-HAS LP? I know that is high availability, but do you expect
them move into this arena?

Ron

iTera is/was, IMO, probably the most robust and easiest to install and
use as well as one of the lower-priced options. We have had real
hardware failures using this product and can role swap a system
(hundreds of miles away) in about 20 minutes. The users saw no
significant difference while operating on the backup boxes.

Today? Well, I see only two real vendors... I still like the iTera
solution and, if priced competitively, any of the solutions that use
remote journaling as their foundation (which I believe, they all do
today) would work out until IBM extends the 5761-HAS LP. Then it's
re-evaluation time.

Also, I found that the DataMirror product (now IBM) is more oriented to
data manipulation rather than simple replication. Better suited for data
warehouse environments.

Hi All,



We are interested in buying a mirroring solution for our iSeries. We have
already contacted some of the providers and would like peoples opinions
about any that they are already using. We've heard the sales pitch, now we
would like to hear real stories, good or bad.



We have 1.4 Terabytes of data spread out across a couple of hundred
libraries. Around 1000 users.



We would welcome any comments.
