Sorry for this very late summary due to a very busy month of july (work,
holidays, world cup...).
I was a little surprised that nobody answer about SUN product HA
Maybe it's because it' s a young product not yet widely installed.
I may conclude from all your answers about HA+ and Firstwatch that both
are rather good products
Both of them share the same origin and provide roughly the same
They are now distinct products and evolve independantly, so may provide
some specific features (GUI, configuration tools...)
Both seems to be well established, reliable, solid.
All of you who are using one of these products seem between rather and
Even if many of you agree that these products are rather easy to
configure and implement, you recommend to pay for consulting services
for the installation and configuration step.
users of HA+ like :
it's easy configuration and implementation, it's reliability.
some extra functionnalities
it's java based GUI
users of Firstwatch like :
it's natural integration with VM and VxFS (SRFS)
it's modularity, reliability
opinions vary from "not what it should be" to "good" for both products.
It seems that most of the problems of support were encountered during
the Qualix/Veritas spliting.
Nobody reports problem that should be caused by having two different
hotlines (SUN and the HA software vendor one).
Veritas would even have a cooperative support agreement with SUN (for
the US zone at least), in order to allow customers to get a single
Your answers really confirmed me that HA+ and Firstwatch were both good
candidates to solve my problem.
My conclusion is that I should look at and test both products.
I'am a bit surprised that nobody really answered about SUN HA Cluster
Most of those who answered about the other products said that SUN
solution should be a valuable one but nobody got a real experience of
Since we've begun testing it, and will probably test HA+ and Firstwatch
too, I should be able to really compare all the three solutions soon.
Feel free to email me your questions if your are interested in such a
