LMS 3.0 Multi-Server Environment

Answered Question
Jan 10th, 2008

I currently have CiscoWorks configured as a standalone, I am looking into setting up a multi-server environment and promote my standalone to master and the other as a Slave server. I'm reading up on the documentation now to get a feel for how much work will need to be done to perform this in the Getting Started with LMS 3.0 guide. The trick question is this another license to be purchased type things for us to do this? Please let me know and also another thing is setting up a multi-server environment is the same as

redundant environment for CiscoWorks?

I have this problem too.

and with the 5000 device license you are allowed to install *ALL* apps more then once -so you can build redundancy on your own.

Correct Answer by David Stanford about 8 years 10 months ago

Master/slave setup is not the same as a redundant setup. It does not mean if one server fails another will take over.

You will need additional licenses if you plan on installing RME, CM, DFM, or IPM more than once.

So if you have a master server with Common Services, RME and CM installed and then a slave server with CS, RME and CM you will need another license.

Thanks for the explanation. Is a redundant set up even possible in CiscoWorks?

Its all a matter of licencing AND number of devices you plan to support. Its not for the faint-hearted and its a decent amount of work. There is no redundancy in Ciscoworks. If you want redundancy you'll need to purchase and install a duplicate autonomous installation. Thats what I have in geographically seperated data center clusters 2,200 miles apart.

Per instance Campus and DFM can support 5,000 devices each. IPM in LMS 3.01 can support 5,000 collectors per instance.

Understood. I'm pretty much in the same boat as you two locations 1,100 miles apart. Just trying to make my life a little easier, but that's doesn't always go swell in this line of work. Right now I'm managing only 290 or so devices in CiscoWorks awaiting quote for the 1,500 license.

Does this statement imply any licenses smaller than the 5000-device one would restrict full installations of *ALL* apps more than once? I'm planning to have two full installations with two 1500-device licenses.

Martin Ermel Thu, 01/10/2008 - 07:49

it implies that any license smaller than the 5000-device one allows the customer to install each app only once PER LICENSE.

If you purchase 2 1500-licenses you are allowed to install each app once for each license (i.e in your case 2x CM, 2x RME, 2x DFM and 2x IPM; CS does not count for licensing- and I think that is what you want to do).

the thing is, that if you purchase only one 1500-device license (each app installed on a single or on its own server) and manage only 600 device you are not allowed to install RME again on a second server (for to build up redundancy or to manage another set of up to 900 devices) - that's what this doc says:

http://www.cisco.com/en/US/docs/net_mgmt/ciscoworks_lan_management_solution/3.0/install/guide/sla.html

I had an issue were a customer has 4 offices in different countries and wants to have the complete suit installed on a server in each office. The question was 'must he buy a license for each office or is it possible to buy one 5000-device license (which was cheaper) and install the complete suit in each office' - the answer was yes, that this is possible as long as the overall device count is not more than 5000.

But this is possible only with the 5000-device or 10000-device license but not with the 1500-device license or below.

yjdabear Thu, 01/10/2008 - 08:17

This is interesting. Does that mean if I have ~700 devices, I could have a single 1500-device license, installed on both servers (or only on the master server in a master-slave setup), and have both servers manage the full ~700 inventory redundantly, using 1400 of the 1500?

Martin Ermel Thu, 01/10/2008 - 08:29

sorry for disappointing you - and if I was unclear....

I said '... if you purchase only one 1500-device license[...]and manage only 600 device you are not allowed to install RME again on a second server ...'

only starting with the 5000-device license you are allowed to install each app multiple times (with one license purchased). With the 1500-device license and below your are NOT allowed to do this.

yjdabear Thu, 01/10/2008 - 08:34

Ah, I got it. Now, I need to find out whether one 5000-device license costs less than two 1500-device licenses. So does that one 5000-device license get installed on each of the four LMS servers, or just the master server?

Joe Clarke Thu, 01/10/2008 - 08:48

I can't speak to exact prices for you, but yes, one 5000 device license retails less than two 1500. I think it's like $15K cheaper.

Technically, now that LMS 3.0.1 supports 5000 devices on a solution server provided DFM and HUM are installed on separate servers, I'm not sure if the multiple servers, one license still holds, but I think mermel is still right since people upgrading from LMS 3.0 to 3.0.1 aren't likely to redo their management solution now that we added for scalability.

What I do know for certain is that each server needing one of RME, CM, DFM, or IPM will need a license. Only CS is unlicensed.

The short end of this is that, yes, each server will need an instance of this license, and no more than 5000 devices can be managed in any given application across all servers.

Martin Ermel Thu, 01/10/2008 - 09:07

if it holds truth for you yjdabear, that it will be around 15k cheaper, you really should get a fee from your company for saving money - and I would only take 10% for leading you on that way ;-)

yjdabear Thu, 01/10/2008 - 10:40

Doh! I was hoping to get away with a "Danke schön!" :P

each server will need an instance of this license, and no more than 5000 devices can be managed in any given application instance.

I have 2 licenced LMS 3.x 10K instances on two clusters. As a cluster, all the application servers communicated via the DCR and licencing server to ensure you do not surpass your total number of authorized devices.

Explore the log files for the licencing daemon and DCR :)

yjdabear Mon, 01/14/2008 - 10:02

Is the "LMS 3.0.1 supports 5000 devices on a solution server" bit referring to an appliance-based offering of LMS 3.0.1? If so, could you post a link to this product bundle?

Joe Clarke Mon, 01/14/2008 - 10:09

The term solution server applies to an LMS server (not an appliance) which has multiple applications installed on it. Compare that to a n application or standalone server which is dedicated to one application (e.g. a server with only CS and RME installed).

chris.mcgarrah@... Wed, 06/11/2008 - 07:49

I have a similar situation. I have 2 data centers. I would like to have a CW server at each location, with each one capable of managing the entire environment. I have 2 full LMS licenses so I don't need a multi-server to split applications for performance, however I would like to share DCRs between the two. Would a multi-server setup be the best way to do this? Thanks.

Joe Clarke Wed, 06/11/2008 - 10:27

Sure. You just make one server the DCR master and the other the slave. You will have one replicated device list, and each server can do the same management tasks for all devices.
