he X86 architecture is pervasive as the platform of choice for virtualising applications – or so you would be lead to believe. If you look at the architecture behind the really big mission-critical applications such as SAP and Oracle you will find that in most cases they are running on large Unix-based systems, increasingly IBM’s pSeries servers running IBM AIX - some refer to as “virtualization on steroids”. Although vast amounts of money are being spent on the server, ensuring the performance and availability of the fibre channel (FC) SAN infrastructure, where the data they are processing resides, is still a major challenge.


The new server family is supposed to ensure application performance but if the SAN infrastructure, switches or storage have problems or


are miss-configured then the application will not perform as expected, and your investment in this new technology . . . no matter how much CPU and memory you throw at that application!


Mistake #1. Don’t confuse performance with Availability


Five nines, six nines, seven nines, are all worthy measurements of availability that many take for granted these days, but the reality is that my laptop gives this kind of resilience but runs slower than I would like.


The measurement for a virtualised application should no longer be a question of ‘is it available?’ but ‘is it performing as it should?’


Big data – not on my virtual server!
