Email Appliance Hardware

The ES1000, ES1100, ES4000, ES5000, and ES8000 are high-performance appliances that are designed to handle a large volume of email traffic.

The ES4000/5000/8000 provide redundant, hot-swappable hard drives and power supplies, and the dual processors help ensure uninterrupted filtering of viruses and spam. See the hard drive and power supply sections for instructions on installing replacement components. All of the Sophos Email Appliances raise alerts via the software and email if any of the hardware is not functioning optimally. The Troubleshooting section describes hardware-related alerts.
