IronPort S660 capacity

Dear Christian,

Could you tell me what is the maximum bandwidth supported by S660 andC660 Web and Mail gateway appliances?

As you mentioned before that S360/370 can handle anywhere between 40 and 60 Mbps,

Thanks in advance.

Are you looking for maximum or recommended sustained bandwidth? The S660/C660 use gigabit ports, but for sizing recommendations it depends on the engines and features you have enabled on the device. Our recommended sustained bandwidth ranges from 91mbps (with all engines and features turned on, not including https) to 182 mbps with only the proxy feature enabled.

Hope this helps.

Best Regards,

Thanks Michael. We have 5000+ users and we currently use S360 WSA as a proxy and for url filtering. Currently the maximum bandwidth received with this setting is only between 40 and 60 Mbps. We have 150 Mbps link.

Kindly suggest whether this is the maximum bandwidth supported by this appliance for 5000+ users. And is degradation in our network performance is due to this? And will the upgrade to S660 WSA resolve this issue? Thanks in advance.

Unfortunately sizing guidance is handled by the account team. For specific sizing guidance for your environment you will need to reach out to your Cisco account manager to assist you.
