I am keen to pursue a single global farm as it will allow us single =

global DR and failover through the use zone preferences and zone =
failover.

On Big Ron's advice, I am looking seriously at the subscriber/publisher
replication model with a non-clusterd master and maybe 5 (max) non =

replication partners!

I believe that, if we cannot trust a Data Store for a global solution, =
then
we cannot trust it for a regional solution which, would be also be
catastrophic if we lost. =20

If the worst comes to the worst we will automagically rebuild the farm =

the shiney new .net MF class libraries included with the MPS3 SDK.  Ok, =
I
just made the bit about the .net MF classes up...but soon..

Citrix touts MPS3 as a real global solution and I am prepared to take =

its
not so much about high availability of the Data store but more to do =

the integrity of the Data Store.

If it all goes belly up, then I'm changing my name to Fifi and moving to

In the meantime, in terms of ensuring integrity of the data store, does
anyone have recommendations of using dscheck on a daily basis on perhaps =
an

switches for dscheck and I wonder if the version with MPS3.0 includes

Thanks again for the discussions buys.. just tell me I am doing the =

I think you are right about the multiple farms. I think Brian's solution =
=3D
is really to have multiple farms managed under a single 3.0 environment. =
=3D
Each farm could have whatever level of SQL redundancy that is =
appropriate =3D
locally with it's own unique farm/data store. In addition, SQL could be
backed =3D up as a whole DB either through replication or scheduled =
backups
across the =3D WAN to DR and/or multiple other data centers.

How about that Brian, a free worldwide architecture analysis!

There are two ways to do it. Merge replication (not supported by Citrix) =
=3D
=3D3D and Transactional replication. The change to a subscriber (remote =
SQL =3D
DB) is
really passed to the Publisher (master copy) to verify that there is no
conflict with the change. The change is incorporated at the publisher, =
=3D =3D3D
then replicated back to the subscriber. It's a really fast process and =
=3D
works pretty well in most cases. It also gives you the "look" of having =
=3D3D
=3D writable copies in all locations. If the publisher is down though =
you cant
change =3D =3D3D the DB but you can get into the CMC and look around =
etc.

But you still have to turn one of the DS DBs into a publisher if you are =
=3D
=3D3D not going to be able to recover the primary.

Big Ron,=3D3D3D20

When you say "SQL server", I assume you are referring to SQL based
relational database servers in general and not specifically to MS SQL
server.

Ok, now I may be being totally over-pessimistic about =3D3D3D =3D3D
publisher/subscriber replication here, but do you think it would be =3D
feasible to operate =3D3D3D something like the following: as part of a
controlled maintenance =3D3D window, point a server to the master copy =
of the
=3D datastore for the duration of updates =3D3D3D to the data store? =
=3D3D3D20

Are the benefits gained by having a simpler replication topology =3D3D3D
outweighed by the amount of effort to provide a maintenance schedule =
=3D3D =3D
like above.  I =3D3D3D am ultra paranoid about a single global farm =
replicated
=3D =3D3D between
8+ servers.

Would you trust the publisher/subscriber model for 8+ Data Store global
single farm? Do you trust DSCHECK?  Am I worrying too much? =3D3D3D20

thanks in advance,

Well. One thing that I can say is any location you have a Citrix server
using a SQL server the DB should be read/write/. Now what do I mean by =
=3D =3D3D
=3D3D3D that? I mean that you should be using a publisher/subscriber =
model
with transactional replication/immediate updating.  This will allow the
=3D3D3D =3D =3D3D changes from servers talking to the subscriber to be =
pushed up
to the Publisher
(master) written into the DS, then replicated to all servers.

The trick with this is that any servers online are going to have changes =
=3D
=3D3D =3D3D3D (of some type, print drivers added, hotfixes added, etc). =
And =3D
these =3D3D changes =3D3D3D need to update the DS. So I would not use a =
straight
push =3D for any =3D3D SQL server =3D3D3D with hot online servers =
connecting to
it. Now =3D to use one as a =3D3D COLD SQL server =3D3D3D you can do =
that. But
lets assume a =3D site loss. You have =3D3D lost 50-75 servers in =
=3D3D3D one site
along with the =3D Datastore. Now you have a =3D3D shipped Database to =
=3D3D3D
another site. And you are going =3D to start installing =3D3D servers =
into that
site to =3D3D3D get you up to =3D capacity. All the shipping did was =
=3D3D handle
your published apps =3D3D3D and licenses =3D for the most part, since =
the 75 =3D3D
servers are "gone" but remain =3D3D3D as =3D ghosts in the DS and you =
still have
to get =3D3D a bunch of servers on line.

Get it?

Big Ron,

Thanks again for your response.

I will be replicating a master read/write copy of the database to =
=3D3D3D =3D
=3D3D perhaps 5 major regional sites and maybe a couple more at a push. =
=3D
=3D3D3D20

Again, back to the DR hot-sites, should I make a data store present =3D =
=3D3D3D
=3D3D there also?

I guess it's a balance between reducing the complexity of the data store
replication and having a truly 'marooned' DR site available almost
immediately.

Personally, from the feelings I got from this list,  I would tend =
=3D3D3D =3D
=3D3D towards keeping the data store replication to a minimum and =
allowing the
=3D DR =3D3D3D scenario the Citrix grace period to restore a data store =
onto an
=3D Oracle =3D3D box which =3D3D3D is pretty straight forward.

When I first asked about data store replication some weeks ago, I =
=3D3D3D
mentioned replication to ten servers globally for a single farm model =
=3D =3D3D
(and most of =3D3D3D the old timers winced slightly).  I am still =
looking to =3D
move forward with a global single farm with data store replication to a =
=3D3D
=3D reduced number, prob =3D3D3D 5 or so... do you guys still hold the =
same
view?

Also, can DSCHECK.EXE be trusted as a signature for health on the IMA =

=3D3D3D data store?

Brian

Simple answer. No it does not need to be clustered. Complicated =3D3D3D =

answer... maybe.=3D3D3D20

I mean the real trick is how many (and what type) of changes will you =

will be =3D
none. We =3D3D =3D3D3D can operate without making changes to the DS for =
a couple
=3D of days. If =3D3D that =3D3D3D is true then you don't need the =
cluster.=3D3D3D20

Replication or shipping of the DB/Logs is needed though for any type of =
=3D
=3D3D =3D3D3D DR. Of course there are drawbacks to this too. I mean If =
you use =3D
=3D3D3D transactional replication then when the primary is gone you cant =

Chaps, I need to draw on your experiences again...

Does the primary IMA Data Store really need to be clustered, or is this =
=3D
=3D3D =3D3D3D more complication than it is worth. KISS principle, etc.?

I appreciate that high availability is important, but isn't the =3D3D3D =
=3D =3D3D
integrity of the database even more important.  Without a Data Store, =
=3D
what's the =3D3D =3D3D3D worse that could happen during the 96 hours, =
you can't
=3D make changes??

If something was seriously wrong the master IMA Data Store cluster node =
=3D
=3D3D =3D3D3D A, would we want the second cluster to take over?  Is =
there not a
