i'd like to know an average disk usage for PA appliance.

Hi all.

somebody who has a datasheet of disk usage for every single appliance including PA 5000 series??

Of course I know it is impossible to calculate correctly because it is depend on customer’s networks environment.

What I want to know is that just rough disk usage for every single appliance.

Below is an example.(below table is an incorrect data. it is just an example for understanding my question.)

Model	Total Disk	assigned disk size for log	internet speed	number of days (roughly)
PA-2020	80G	50G	100M	7days.

Model

Total Disk

assigned disk size for log

internet speed

number of days

(roughly)

PA-2020

80G

50G

100M

7days.

Regards,

Eugene.

There's no hard and fast answer for this.

The amount of disk space used for logs and how rapidly it fills is related to how much logging you have enabled/turned on. I've now had my PAN devices in operation for approximately 6 months, and have used only 48% of the 125G allocated on the logs partition - but while I log traffic, I *only* log URL filtering for certain categories, not every single transaction - which means the log load is a lot lower than it could be.

If I cranked the URl filtering up to logging every single transaction, regardless of allow of deny status, I'd eat log space a lot faster.

As always, YMMV.

You can calculate the disk usage/log retention of your network by querying 2 stats in the CLI: logdb-quota and the log. In this example, the traffic log usage = 15G and the oldest log is 2011/04/04 06:16:20. With this information, you can get a good idea of how many hours/days of traffic log to fill up 15GB. You can use the same method for threat log.

Note that the URL logs & threat logs are combined together in the threat database. You can also reduce the disk usage for URL log by setting some categories like content-delivery networks, dynamic-contents, and web-advertisements to 'Allow' which is permit & not log.
