Instantaneous Failover and Failback
The ACA-2500E is the first product in the market to guarantee instant Failover and Failback in the event of Exchange server failure or planned downtime, providing non-stop, transparent email operation for end-users. This is achieved via Teneros patent pending Instant-On™ technology. Old-fashioned backup or standby server solutions cannot deliver this non-stop mission critical application continuity.

No Intrusion to the Exchange server
The ACA- 2500E is the only product in the market that does not require installation of complex and intrusive software on the Exchange server. No modifications are required in the Exchange, Active Directory, or DNS infrastructure. This unique patent pending capability of the Teneros Plug-and-Go Appliance Architecture eliminates the need for Exchange downtime during installation and ensures the stability of the Exchange environment.

Easy Installation and no additional IT resources required
Installation and setup of the ACA-2500E can be completed using the web interface in less than 15 minutes and does not require Microsoft Exchange expertise. No ongoing maintenance or IT resources are required because the Appliance Architecture automatically and securely monitors the appliance and applies updates and patches. The appliances anti-intrusion and anti-virus systems are also monitored and securely updated.

Protection from Database Corruption
The ACA-2500E uses Teneros Transaction Integrity Validation technology to check email data before and after replication, preventing Exchange data corruption from being duplicated on the Teneros Application Continuity Appliance. Old-fashioned continuity solutions for Microsoft Exchange that use disk, block, or file level replication cannot prevent Exchange server email data corruption from being duplicated.

Secure Access
The Teneros Application Continuity Appliance prevents unauthorized access to the appliance. Accidentally destabilizing or malicious user actions are forbidden. This security ensures that the ACA continues to protect the Exchange server reliably and securely.

Data Restoration
The Teneros ACA-2500E provides data recovery features that enable the Exchange email data to be recovered in the event of backup corruption or loss. Upon Failback, the Teneros Application Continuity Appliance will determine what email data is missing from the repaired or updated Exchange server and restore it. Restoration can cover any amount of email up to the complete mail store.

Self Healing
All Application Continuity Appliances leverage the Teneros Multi-System Resiliency technology, which uses independent error detection and recovery systems within the appliance to maintain the availability of the appliance. These independent systems continuously monitor, detect, and repair soft errors. The Teneros ACA also automatically reconfigures and replicate objects as necessary if hardware failures occur. The Teneros Multi-System Resiliency technology assures Always-On performance.

Regulatory Compliance
The Teneros ACA-2500E is designed to ensure that critical email records are complete, accurate, reliable, and accessible for their full retention periods.
