PIX 525 Scalability

[haithamnofal]

Hi There,

I'm implementing PIX 525 FW in my network and I have a setup as follows:

100 Mbps internet link, a web server DMZ where I have 4 web servers, an application DMZ where I have application servers, and a DB DMZ where I have my DB servers.

I'm expecting a heavy network and the number of users accessing my applications can reach 50,000 users and even more in the future. Based on this info, do you think might I have any problems related to scalability? Do you think that the built-in RAM which is 256 MB will give good performance results or do you think I might need to upgarde my RAM?

Appreciate your feedback.

Thanks,

Haitham

While configuration files up to 2 MB are now supported on the PIX 525 and PIX 535, be aware that such large configuration files can reduce system performance. For example, a large configuration file is likely to noticeably slow execution times in the following situations:

While executing commands such as write term and show conf

Failover (the configuration synchronization time)

During a system reload
