White Papers: virtualisation

Virtualisation brings the potential to deliver dramatic savings in terms of server count, footprint, power consumption and cooling requirements for data centers. For all its advantages though, virtualisation also brings some unique challenges. The power and cooling infrastructure—which may have been quite sufficient for pre-virtualization needs—could easily become inadequate when data center performance patterns are radically altered. The good news is that there are practical and affordable ways to address these challenges and improve data center efficiency in the process. This paper looks at some of the power-related challenges and the readily available technologies to address them.

Virtualisation in IT has brought many significant benefits and changed the way data centres are designed and operated. In a virtualised data centre, applications, services and databases run on fewer physical servers than before and the operator makes significant savings in power consumption, cooling and infrastructure expenditure.

In this Research Report, Clabby Analytics explains why we believe that IBM System z 196 mainframe — when configured as a Linux/cloud consolidation server — can help enterprises save BIG MONEY when running heavy I/O workloads.

All too often in IT generally—and in storage infrastructures specifically—there’s a tendency for an “assumption gap” to exist. This paper is an attempt to close that gap; in a pragmatic and accessible manner, it covers the real value of storage virtualisation (from both business and IT perspectives) and offers explanations of the varying storage virtualisation approaches with advice on how to make a technology and vendor decision.

Over the years, virtualisation has been proven to reduce costs, increase flexibility and improve business continuity—these are some of the key benefits of virtualisation. But first-generation virtualisation solutions were often custom designs that constrained scalability, increased IT complexity, limited security and siloed management— which led to significant business impacts.
