Bandwith consumption

[DCIM_Support]

Do we have any guidelines or documentation on network bandwith consumption between DCE and the devices?

I guess it is "small" but do we have any numbers that quantify this?

HI Christian,

We have no detailed official documentation requirements for DCE bandwidth consumption, as it differs from environment to environment. There are numerous factors that contribute to bandwidth consumption i.e polling frequency, (if your system polls every 10 minutes as opposed to every 1 minute you would have less traffic), how many devices are being polled, how often the devices are alerting, if you are using surveillance etc. Not only is SNMP data being polled, other data is also being polled. We pull the DDF from the devices itself, when any configuration changes are being made to the device through DCE, the config.ini is being transferred. 

You should be using a 100bt network minimum. It is possible to limit the bandwidth, by reducing the polling frequency of the data being polled from the default 5 to 10 minutes. How much data being polled can not be changed.

Ok, let me re-formulate my question 😉

How much data is (on average?) sent per polling per device? Data Center Expert is polling a device, the device sends some data back to DCE (which properly depends on the device type), do we have any information on the amount of data being transmitted?

There are network analysis tools you can use to check how much your bandwidth your DCE is using. Our Power strips were pulling ~880bits/sec (1.4 Packets/sec) on a two minute polling frequency. Unfortunately, you loose granularity on the data when you increase the polling cycle. It will only pull data at that instant and also when a trap is sent. I wish it could pull the max, min, and average which happened between polling cycles and the actual value when polled. Regards, J

Hi Christian,

This is strictly just an estimate, but during a normal device scan, the packet size can vary from about 5-12KB per SNMP device being scanned.
