This is clearly where I have a lot of reading to do. To clarify, high
availability isn't the absolute end-goal here, the end goal is to stay running
even and a little manual intervention is acceptable (still better than
recovering a box), but it would be great if it just sorted itself out.
Ah the man who makes the HAProxy VM! I did think about trying that, obviously
the beta/lack of (official) support is a concern there, nothing personal you
understand.
I'll look at that TechEd session when I have a little time - I'm just keen to
avoid more Windows boxes if they don't bring any
Doesn't stay running and high availability mean approximately the same
thing?! :)
I'm a bit confused how you've got a CAS array but you're not currently using a
NLB/HLB. Actually, it makes a bit more sense if you only have one CAS. Is that
right?
So, if you only LB 443 and 80, you have two
We have 1 CAS as we only have one server, but I was advised to create the CAS
array object when we setup the 2010 box, and before we moved and mailboxes, as
apparently it makes life simpler if you want to setup a real CAS array.
This is where I thought we wanted to be load balancing MAPI but
It's worth setting up a CAS array logical name and assigning it to the Mailbox
Databases even if you have a single, combined roles server. It makes things
easier down the line if you add HA in but don't want to move mailboxes between
databases etc.. (eg another combined roles box, DAG, LB, CAS
And to balance RPC I guess I'm back where I started with the docs from
loadbalancer.org stating you need to assign a static RPC port?
Any downside in doing so?

I don't think there is a particular downside. When the US wakes up I am sure
Michael may have a different take, but assigning a static port avoids having to
load balance a large number of TCP/IP ports for RPC. In essence to set static
ports it's just a couple of registry entries on each server
I'll say now that we don't use static ports.

Even on the LAN? Don't you then run into issues where you need an LB that can
handle SSL from all your clients rather than just the RPC/HTTP/ActiveSync/OWA
ones?

Even on the LAN?
So what is the pro of that approach over doing LB for RPC too? Keeping in mind
I'm trying to avoid client disruption if/when we do this?
I'd assumed, incorrectly probably, that using RPC over HTTP on the LAN isn't
all that common?
If nothing else it makes a big difference in the level and
I would say if you are doing LB for RPC, then it's worth sticking to the
vendor's Exchange recommendations for the LB you choose - which are typically
going to state using static ports for RPC.
I know of organizations that are requiring RPC over HTTPS, but the majority I
deal with use RPC
Every Enterprise level customer I do Citrix work for uses RPC/HTTP for their
Exchange stuff.

Does it require both the Windows 2008 R2 Enterprise edition and Exchange
