Neverfail IT Continuity Engine v7.1.1 - Release Notes

Follow

Summary

This Knowledgebase article provides information about this specific release of Neverfail IT Continuity Engine v7.1.1

Overview

IT Continuity Engine v7.1.1 is the latest addition to the Neverfail family of continuous availability technologies that has been optimized for use in VMware virtualized environments. It provides product capabilities and benefits similar to Neverfail Heartbeat, but with a highly simplified and automated deployment process. IT Continuity Engine's deep integration with VMware vSphere provides complementary add-on HA/DR value in addition to the native VMware BCDR oriented solutions such as HA, SRM, and so on.

What’s New

Engine 7.1.1 builds on the core features and benefits of Engine 7.0 by adding the following:

  • Tertiary Support
    • Create new trio (tertiary) deployments via an easy to use wizard
    • Transition an existing pair (HA/DR) to a trio (tertiary) deployment
  • Streamlined Deployment Options
    • The ability to customize IP configurations on each node during each deployment by allowing you to select which IP will be your public and which interface you want to use for the Neverfail Channel
    • Support for multiple NICs. Use a single or dual NIC configuration while using the Engine deployment wizard.
  • Redesigned Network Management
    • A complete redesign of packet filtering to leverage Windows Filtering Platform thus restricting network access on passive nodes without the need for hardware specific network interface device drivers.
  • Redesigned User Interface (Web Services)
    • Engine Management Service now has its own web portal service which enables management and deployment without the need for VMWare specific plug-ins.
  • Licensing Enhancements
    • Offline key application process. This now allows for pre-authorized license keys to be deployed quickly and easily for systems that are not connected to the internet.
  • Bundled Plug-ins
    • Neverfail IT Continuity Engine now includes common plug-ins bundled into the setup .msi file and installed automatically.
  • Citrix Xen to VMWare as a Deployment Option
