Achieving Century Uptimes with Shadowbase Active/Active Technology

Achieving Century Uptimes with HPE Shadowbase Active/Active Technology

An HPE Shadowbase active/active system architecture provides disaster tolerance by maintaining a network of independent processing nodes, each having access to a common replicated database. This architecture eliminates the uncertainty and cost that exists with an active/backup...

Choosing a Business Continuity Solution to Match Your Business Availability Requirements

Business continuity encompasses those activities that an enterprise performs to maintain consistency and recoverability of its operations and services. The availability of application services provided by an enterprise’s IT infrastructure is only one of many facets of...

Hardware vs Software Data Replication for Business Continuity (Disk/Cache Flushing vs. Transactional Replication Engines)

Business continuity encompasses activities that an enterprise performs to maintain timeliness, consistency, and availability of its data, operations, and services. Application availability depends upon the ability of IT services to survive any fault, whether it is a server failure, a network...

HPE Shadowbase Solutions and Pathway Domains—Perfect Together!

It takes two to tango! It is of no use having data available on alternate/takeover systems if the applications required to provide the business services are not also available when needed. HPE Shadowbase data replication solutions provide all the capabilities necessary to keep...

HPE Shadowbase Solutions in a Big Data World

A big data analytics system typically requires a large network of tens, hundreds, or even thousands of heterogeneous, purpose-built servers, each performing its own portion of the task. All of these systems must intercommunicate with each other in real-time, and integrate with high-speed, flexible, and reliable data distribution. The HPE Shadowbase...

Shadowbase Synchronous Replication — Product Overview

Shadowbase synchronous replication (Shadowbase Zero Data Loss, or Shadowbase ZDL) resolves two key issues of asynchronous replication: data loss on source system failure and data collisions when running an active/active environment. By eliminating data loss and effectively setting the Recovery Point Objective, or RPO, to zero, Shadowbase ZDL protects...

The Benefits of Switching from Scale-up to Scale-out Architectures

Keeping up with user demand and managing a service outage or brownout is a significant challenge for IT departments. The traditional scale-up approach suffers from significant limitations and cost issues that prevent it from satisfying the ever-increasing workloads of a 24×7 online society. The use of massively parallel processing and scale-out architectures is the solution,...

Using Shadowbase to Eliminate Planned Downtime via Zero Downtime Migrations

Using HPE Shadowbase Software to Eliminate Planned Downtime via Zero Downtime Migration

Downtime – whether planned or unplanned – is costly. This paper explains how to totally achieve no application downtime when performing migrations, upgrades, conversions, or other disruptive system activity, regardless if performing a homogeneous or heterogeneous...
