convert or upgrade small to medium appliance NAC / XMC / Anlaytics

info_systemhaus — Wed, 31 Oct 2018 13:47:00 GMT

Hello Comunity,

we made a POC last year with 8.0.5.18 Netsight / Purview / NAC on a customer location...

Now .. "we will buy ist . it works great" ..
"please convert it to medium size because we need analytics "
but no "New install" because we did a lot of integration ...

How can i upgrade or convert a small appliance to a medium appliance ?
Should i convert it alone or can you combine this with an upgrade to last version ?

Try to set the CPU/RAM according to the specs in the datasheet:

https://documentation.extremenetworks.com/netsight/8.1/9035435_InstallationGuide.pdf

change the nsserver.cfg XMS and XMX so java uses the resources

root@netsight:/usr/local/Enterasys_Networks$ cat /usr/local/Enterasys_Networks/NetSight/services/nsserver.cfg
-Xms8g -Xmx12g -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=../../nsdump.hprof -XX:MetaspaceSize=128m

that would be perfect ,
but can you or anyone from extreme confirm that only change of ressources und Limits will unlock the possibility to use Analytics ?

is the difference from Small to medium to large/Enterprise only the amount of ressources ?
That would be true if it´s an "elastic appiance" .. i know that with EWC it´s correct but i found never Information about XMC/ NAC /Analytics

you need a seperate analytics "purview" appliance
and you need NMS-ADV license

basically you can have XMC small appliance and use analytics

you got 3000 flows in nms-adv license. if you have more you need a analytics license
for network response time you need an s-series switch or identifi wireless controller

Hello Anton,

you didn´t understand me ..  of course i have a pureview appliance..
But it was installed as a "Small" deployment and the small deployment has as per description no possibility to make analytics .. you need the medium deployment..

Thats why my question if the difference between small and medium is only the amount of ressources and settings in the nssserver.cfg ?

WIth Analytics you may need more hard drive space for your statistics.Not only CPU & Memory.

My approach would be:
- backup your configuration in the GUI
- export the backup from the PoC virtual machine
- install new production VM
- copy the backup to the file system of production VM
- restore the backup in the GUI

Please be aware following information is not part of the backup and additional manual file transfer is needed:
- MIBs
- Connect settings
- Operating system settings
