[cisco-voip] CM 4.1

Tue Dec 14 12:29:55 EST 2004

Back to the Standard Cisco answer "It Depends..."  I can't find it now,
but the minimum requirement is 1GB.  You really need to look at how much
memory is being used today. Watch these numbers for several days, at
different times of the day. 

The easiest way I have found to check memory consumption is through
Windows Task Manager.  Task Manager -> Performance, Physical Memory (K)
on the left shows "Total", "Available" and "System Cache". "Available"
is how much RAM is not currently being used.  

"Commit Charge (K)" (bottom left) has "Total", "Limit" and "Peak".
"Commit Charge Total" is the combination of Physical RAM and swap space
available.  "Total" show the current consumption of RAM and Swap Space.
"Peak" shows the maximum amount of RAM and Swap space consumed since
last reboot.

As with any Windows system, it is better to have processes running from
RAM that Swap space.

I had one customer who did the 7815 mid-market bundle which originally
defaulted to 512MB (defaults to 1GB since July 2004).  With 4.0(2) and
25 users, the had about 4MB of available memory.  They increased to 2
GB, yes it was overkill but memory is cheap and they didn't want to do
another upgrade in 12 months.

I also have a customer with 200 IP Phones, 75 Attendant Console users
with MCS7835 (1GB) on CCM 3.3(4)SR1.  The had 10MB of memory free.  They
upgraded to 2GB.

How much memory you need is really dependant on your environment.  Cisco
docs are confusing on device weights.  The basic memory problems relate
to the SQL database.  The more entries in the database, the more memory
SQL consumes.  Entries include Route Patterns, Translation Patterns, IP
Phones, Gateways etc.

Our CM servers are running a Gig of RAM.  What will we need?

We have been very happy with 4.1(2).  4.0X had some problems.  You
should really consider a DRAM upgrade, 4.X appears to consume more
memory that 3.3(4)X.

I am actually very interested in this as well, as far as the differences
people are seeing in going to 4.1(x).  We are rolling out a new Cisco
VoIP network and the consideration to roll out with a brand new version
of CCM was very tempting to us because of the features and functionality
inherit in the new version that most resembled what the Telecom team
here was used to.  But because we really didn't want to deal with both
the complexity of a brand new phone system and a brand new version of
CallManager that was untested, our pain-threshold limited us to going to
4.0.  

We are definitely looking to migrate and upgrade to 4.1 in the near
future, after further rollouts are done and more testing has been made.
If any of you have tested or are making the transition to 4.1, please do
share your experiences.  I will do the same once we get to that point.

Thanks,

Craig

We are planning on going from 3.3(3)sr4a to 4.1(2)srX in April. It's
rumoured 4.1(3) will be out at that time, but we won't have had enough
time to test to implement that.

The biggest problem will be that you have to read all the release notes
from your version and on. Going from 3.3(4) poses a bit of an issue,
since there were features released in 3.3(4) that were not included in
4.0(x). You'll have to check with your Acct.Team/TAC to make sure that
every new feature you are using in 3.3(4) is included. 

One problem we will face is the asthetic difference on the phones for
the new loads. What makes it more difficult is that many of those
difference are not documented (nor does it sound like they will be).
I've got a case open with the TAC to confirm whether or not these were
missed or simply not documented. And if not documented, what is the
chance of documenting these in the future. We can't be expected to
upgrade phone loads without being prepared for whatever differences they
may bring. For example, I'm upgrading to the latest 7912 firmware and it
changes the menu spacing which forces the directory application off to
the next page. 

I'm hoping the list will share any 'gotchas' during/after the upgrade
process. One I know of is that voicemail ports are handled a little
differently and require reconfiguration before voicemail access is 100%
available after an upgrade.

	Anyone on the list using CM 4.1?  Did you upgrade from 3.3.4?
If so,
	any problems upgrading?  I'm going to upgrade as soon as it
comes off
	limited deployment.  

	Thanks
