High Availability (HA)

In this network communications era, the world expects High Availability in the form of always on services. Service disruptions are now headline news material. More importantly, downtime has a direct financial impact to business. Even conservative market research estimates for the average cost of each hour of unplanned downtime for "mission critical" applications start in the high tens of thousands of dollars. The impact to e-commerce and cloud computing related services is higher.The Nexionprol HA Solution

The Nexionpro HA solution comprehensively incorporates server, storage and network virtualization technologies, to provide an Active-Active HA implementation that manages resources end-to-end to ensure availability and resilience in a single package.

Key Highlights

  • Multi-site, multi-technology integration with tiered HA and DR architecture provides comprehensive replication and recovery for heterogeneous storage and Server Infrastructures
  • Application-Centric HA with end-to-end (Server, Storage and SAN) failover capability
  • Active-Active solution reduces costs by eliminating the need for passive nodes

Disaster Recovery (DR)

According to a recent Forrester Research survey, 27% of global companies have declared at least 1 disaster in the past 5 years. Disruptions resulting from these disasters can have a serious impact on business including revenue and productivity loss, damage to business reputation or even compliance,SLA related penalties.

Businesses do understand the need for DR but the complexity involved in choosing a DR solution that balances the needs of business with a manageable process that can be implemented and validated at a reasonable price, represents a formidable challenge to any IT staff. Consequently, many DR plans, products and implementations end up as shelf-ware and prove ineffective in the case of a real disaster. Additionally, typical passive node clustering solutions that just waitidly to takeover in case of a DR event are simply not cost effective and efficient.
The Nexionpro DR Solution

The Nexionpro DR solution comprehensively incorporates server, storage and network virtualization technologies, to provide an Active-Active DR strategy that works end-to-end to continuously ensure that all the various DR sites are synchronized at any given time. The system is designed to failover correctly based on RTO and RPO requirements when application performance falls below established parameters.
This approach allows the DR planning to be incorporated into the application and into IT resource allocation planning, design and implementation phases to ensure that the appropriate failovers occur to restore the application to its expected state when a disaster strikes.

Key Highlights

Multi-site, multi-technology integration with tiered DR architecture provides comprehensive replication and recovery for heterogeneous storage and Server Infrastructures
Application-Centric DR with end-to-end (Server, Storage and SAN) failover capability
Active-Active solution reduces costs by eliminating the need for passive nodes
Enables testing and validation of DR configuration beforehand

Performance Optimization

In a shared computing, network and storage environment, business applications often contend for same resources which, if not properly managed, can result in poor response times leading to user frustration and productivity loss. Experience shows that:

  • 75% of performance issues are the result of poorly distributed workloads, or disruptive workloads or inappropriate application of technology or changing application requirements
  • 15% are resource sizing related issues
  • 5% are due to a expectation mismatch between users and technology capabilities
  • 5% are break-fix and other fault management related issues

    While there are many solutions available for individually managing Server, Network and Storage resources, optimizing application performance requires a comprehensive approach. Diagnosing and optimizing application performance requires analysis and correlation of configuration and performance data across all IT resources. This is labor-intensive and requires multi-domain expertise which is not easily available.

The Nexionpro Performance Optimization Solution
The Nexionpro performance optimization solution is designed to help optimize application performance by continually monitoring and dynamically reallocating Server, Storage and Network resources according to defined business criteria and priorities. The Nexionpro performance optimization solution essentially encapsulates knowledge and best practices from multiple domains and provides a framework that orchestrates and automates otherwise disjointed processes that are also labor intensive.

Key Highlights

  • Application to spindle configuration and performance metric collection and storage facilitates remote analysis
  • On-demand performance diagnosis using stored history eliminates the need for reproducing faults for root-cause analysis
  • Business priority and workload analysis is used for recommending reconfiguration of IOPs and throughput
  • Workload analysis is used for bandwidth calculation for replication
