I thought I would ask a couple question in here to see if anyone has any
answers.

1. Is it ok to run the CAS and Hub Transport on the same server?

2. Is it ok to run the CAS and Hub Transport roles on a VM server?

3. Is there really a need to cluster if you are using SAN Snap Mirror to
replicate data across to a DR site? The server already boot from the SAN so
why use a cluster like LCR or CCR when I can just turn on the server at the
DR site and have the same image?

Number of employee: 65

Currently 2 Exchange 2003 Servers with a total of 600GB information Store
and using Symantec Enterprise Vault 8 for archiving.

Thanks for the help

Ah. SnapMirror. OK. As an employee of the makers of SnapMirror....
SnapMirror sits in competition to SCR. SnapMirror is a lot better than
SCR when you need to move back from the DR site into production. SCR
is no better or no worse than using SnapMirror to go TO the DR
environment. I won't go any further with that but safe to say I have
conversations with our customers on what to implement, when and why.
Sometimes we suggest SCR, sometimes SnapMirror. It's all about the
customer.

You would never use LCR with NetApp because you can roll back to a
previous Snap just as quickly as initiating an LCR copy. It's a 100%
waste of storage for the benefit of no more than "8 seconds" worth of
uptime.

CCR is a different matter. Lots of our PS staff are none too keen on
CCR because it's generally more complicated than conventional (I'm not
really sure about that) SCC. If you have at least two pairs of Filers
then CCR makes sense if you're putting different servers against
different heads. If you have a single clustered pair then your second
best option is to put the two servers on oposing heads. If you have a
single setup (FAS2020 for example) then CCR is pointless.

Booting from SAN is excellent. If you have enough bandwidth to drive
service from location B whilst the users are in location A then
mirroring the LUNs (ok FlexVols) to the other site and running the DR
box using the production image is an excellent idea.

What FAS are you on, what are you mirroring to? You can reply to my
email offline.

I would have a conversation with your VAR (partner) or your wonderful
storage vendor directly on this to give you a view of all your
options. This newsgroup isn't great for a detailed analysis.
