High Availability Software 'everRun'
A reliability solution that achieves a high-reliability virtualization system that is simple, robust, and cost-effective.
"Stratus everRun" is an enterprise software fault tolerance product that achieves a fault-tolerant system with a pair of IA servers, providing Software Defined Availability - a software-controlled availability solution. With excellent simplicity, robustness, and flexibility, everRun eliminates the need for modifications to existing applications or complex installations, enabling straightforward operational management similar to that of a single system. It applies Stratus's continuous availability technology, developed over more than 40 years, to a wide range of application environments, delivering the necessary level of availability for your systems. We offer the software fault tolerance products "everRun Enterprise" and "everRun Enterprise Single PVM" in FT/HA mode, as well as the hyper-HA product "everRun Express" in HA mode. 【Features】 ■ Simple configuration ■ Peace of mind with no downtime ■ Overwhelming ease of use ■ Excellent flexibility *For more details, please refer to the PDF document or feel free to contact us.
basic information
**Features** **"Simple Configuration"** - Only one license of everRun software is required for a pair of IA servers. - No external shared disk is needed, achieving high reliability for the system at a low cost. **"Non-stop Reliability"** - The memory and disks of the two IA servers are always synchronized, and the network is redundant. - All responses to hardware failures are automatic, avoiding processing interruptions and data loss. **"Overwhelming Ease of Use"** - Installation takes about one hour, with no complex settings or specialized skills required. - Operates with the same usability as a single system, significantly reducing operational management workload. - Snapshot functionality is included as standard, making it easy to back up the system. **"Excellent Flexibility"** - Supports a wide range of server specifications and guest OS environments. - Virtualization functionality is included as standard, suitable for server consolidation and multi-tenancy. - Availability levels can be set for each virtual machine (FT/HA). - External storage can be connected, allowing flexible database configuration with multi-storage group management functionality. *For more details, please refer to the PDF document or feel free to contact us.*

【everRun's Continuous Operation Mechanism】 The two IA servers with everRun installed are always synchronized in data and memory through the state point feature, and the network is set up with active-standby redundancy. Virtualization software is integrated, allowing applications to run on the guest OS within virtual machines. In the event of a server failure, the system automatically detects the failure, isolates the affected area, and continues processing on the other server. Since there is no failover of the virtual machine during this process, there is no impact on the OS or running applications, thus avoiding time lags and data loss. Maintenance can be performed on the failed server without stopping the system, achieving continuous operation of the system.
-
Differences in Redundancy Levels The everRun virtual machines have two availability modes: FT mode (non-stop type) and HA mode (high availability, failover type), which differ in the level of redundancy between two physical servers.

"Differences Between General HA Cluster Systems and everRun" ★ Standby Method - In the case of cold standby, it is necessary to switch the line, power on the standby side, start up, and confirm the operational status after startup. - In the case of hot standby, it is necessary to switch line addresses and confirm the operation of applications. ★ HA Cluster Configuration Initially, the introduction and configuration of shared disks are required, followed by cluster configuration and verification. Knowledge and skills in both areas are necessary. ★ Use of Shared Virtual Disks Both cluster and virtual shared disk technologies and knowledge are required, and operations will be conducted at each respective layer. ★ Fault-Tolerant Products Fault Tolerance (FT), unlike other availability technologies mentioned earlier, is designed not to minimize downtime but to achieve continuous availability and uninterrupted operation.
