Brian,

You say Consolidation. Are you going to consider datacentre consolidation=
 as well?

I gather if they're upgrading from 1.8, it implies a major project to rep=
lace all their current Citrix servers with new ones, new OS, etc, so it's=
 an opportunity to do some serious consolidation as well (though it depen=
ds what applications they run), reduce the number of datacentres, increas=
e security, improve manageability, reduce costs, etc.

Citrix =3D access and access =3D Citrix. So Citrix would position itself =
as the platform through which all users access all corporate data.

Are the citrix servers considered part of the office infrastructure (like=
 desktop replacements) of part of the application (like single published =
application per farm). Also, what is the roadmap of the company? Where ar=
e they going to go with datacentre management, desktops, etc. over the ne=
xt 2-3 years?

IMO, there is no right way to design a farm unless you have spoken to the=
 CIO first and got a good idea of where the company is taking it's IT inf=
rastructure, so to consider answering the question correctly, we'd need t=
o know this first. Then we can talk technical.

Regards,

Jeremy Thomas

Subject: [THIN] global or multi regional citrix farms



Hi all,

Bit of an urgent request here... I need you guys that have designed big C=
itrix
farms to give me the benefit of your experience, Brian.. Jim et al... you=
 know
who you are....

I have a customer who currently has around 50 1.8 farms dotted around the
globe.  They are looking to consolidate into a Presentation Server III fa=
rm.
The intial thoughts were to simply have one global farm with a highly
resilient datastore replicated around the globe.

My concern with the single global farm firstly, is the ability to maintai=
n the
integrity and availability of the Datastore.  The client are looking at O=
racle
on Sun kit for the Datastore.  Despite their expertise on high availabili=
ty
database solutions, I am still aware that the datastore can be easily
corrupted, i.e. running chfarm whilst the CMC is open...

My question is this... what would you advise for a 20,000 user Citrix far=
m
split approx. equally across some 10 countries?

Are farm failover solutions available?



Thanks in advance...

B
