Boot from SAN is something that you should use Windows 2003 for and be very
careful to align the stars of configuration details to make sure it is all
supported/recommended.  Risky?  No more than booting locally really outside
of the extra configuration details you need to be aware of.  Check with your
SAN vendor and specifically the HBA vendor to find out what's required etc.

FE/BE is designed for scalability.  Doesn't sound like you really need
scalability.  You *could* do it with one server.  FE servers also offer some
advantages if you need to provide some services on the internet such as OWA,
OMA, AS, etc that you can't get with just a standalone server.

Depends on what you want to do whether or not you need a FE server.

Subject: [exchangelist] FE/BE vs standalone


I am trying to decide on the best architecture for a new installation.
This will have 350 users, average mailbox sizes and traffic (100MB mailboxes
typically).  I am OK for figuring out how much space I need.

Question is architecture:

a) for this many (or few?) users, should I consider a front end/back end
configuration or is a single-server installation sufficient (e.g. a P4/3GHz
server with 1GB RAM) ?  What would the benefits of FE/BE be over stand

b) I will also set up a clustered active/passive backup server.  Are there
any recommendations regarding FE/BE in a clustered environment?

c) The customer has a SAN and seems keenly interested in the notion of
setting up the server to boot off the SAN.  Is this a recommended method
(best practices)?  Booting workstations off of the SAN is one thing but
booting mission critical servers off of a SAN might be risky?  Thoughts?

best regards
Mike Salim
