Affordable load balancing, peak performance.
The E250si takes the guesswork and expense out of server load balancing. Regardless of the application or environment, the E250si scales your servers while staying within your budget.
Load Balance More Than the Web
 Web applications aren't the only servers in the data center. With the E250si, you can load balance Email servers, Portal servers, ERP applications, File Transfer (FTP) servers, Terminal Services and much more. You'll have scalability and high availability for all your applications in one seamless step.
Scaling to Capacity
The high performance engine of the E250si lets your site grow as your needs grow. With throughput capacity up to 40 T1s, you can rest assured this engine won't be running out of gas anytime soon. In addition to high throughput, the E250si scales to support more than 1000 servers.
Features
- Load balance Web, email, file transfer and database protocols

Bringing High Availability to Your Network
Scalability is meaningless if your servers aren't available. With the high availability features of the E250si, you can have a fully redundant infrastructure. The E250si automatically protects you against any kind of outage by switching to a secondary unit in the event of a hardware failure. In addition to keeping itself up 24x7, the E250si will automatically redirect traffic away from failed servers so users only see 100% functional applications.
Managing upgrades is also easier with the E250si. The high availability technology lets administrators make network and application changes with zero downtime. Which means no more midnight upgrades. If users don't need to be at the data center at midnight, why should you?
Predictable, Reliable and Consistent
The bottom line for any business is making sure services offered are predictable, reliable and consistent. Offering that quality means having an infrastructure that promises the same. The E250si delivers on that commitment.
