What should be taken care if increasing the RAM of Primary Poller?

Jump to solution

Hi All,

Would like to know what all should be taken care of if i m planning to increase the RAM for Primary Poller which is a physical Windows server 2008 Standard Box.

We are getting lot of spikes on memory for Main poller and when approached Vendor they have identified that we dont have recommended hardware.

We are currently running on 2015.1.2 version. Have NPM, NCM, NTA, IPAM, VNQM and UDT modules.

Primary Poller is also having NTA for which a LUN is provisioned and data is stored there.

SQL server is on different box.

What is the number of nodes that you monitor and / or you want to monitor?
With this data we can talk about a setting for the servers.

If you are asking what you need to do physically to increase RAM, then just shut down orion services, shut down the server, add your ram and fire it back up?  If you are asking how much you should add, then that goes back to cjfranca‌'s response of what are you trying to monitor - number of elements etc

Hi, cjfrancaautomag928

We have close to 2k nodes currently.

Actually our server team were asking us if we can go for P2V option for upgrading RAM. I did few search on this and i guess its not a very good option to go with.

Your thoughts?

**SQL Server Hardware Recommendation**

3 GHz, dual core processor or better. This will work for all size licenses. Do not use

less than a 2 GHz processor for any Orion SQL server.

Best Practice use RAID 10

2 x Raid 1 disk (Mirroring) For operating system

2 x Raid 1 disk   (Mirroring) Place pagefile here and also can be used for applications and ad hoc Stuff

4 x RAID 1 +0 Stripping and mirroring for database files (2 partitions 1 for Data File and 1 for Log File)

Install Orion Platform v2015.1.2 Hot Fix 6, that you can download from the customer portal.

It resolves CPU and MEM issue. Memory utilization dropped from 80 to 50% in our case.

Hi Deltona

What kind of issues u have come across for CPU and Memory before hotfix deployment?

Currently for me its happening on random manner where Memory shoots up continuously and it ends up in console inaccessible. recently URL was getting re-directing to blank page although services were running fine. Then only option which resolved was running the configuration wizard.
