Network Performance refers to the level of quality of service of a telecommunications product as seen by the customer. It should not be seen merely as an attempt to get "more through" the network. Performance can also be modelled instead of measured; one example of this is using state transition diagrams to model queuing performance in a circuit-switched network. |

Today’s complex IT infrastructures are dynamic, multi vendor engines made of frequently changing components and technologies. The complexity of the infrastructure and the continual changes caused by business demands often lead to faults within the infrastructure. A fault in a single device can have a ripple effect that causes performance and availability problems for many users. The ripple effect also makes it difficult to pinpoint the root cause of the fault.

Many IT Managers will be familiar with the ‘disk or die’ ultimatums that a disgruntled system can issue. If the system demands feeding and threatens to shut down if it doesn’t get more disk to chew, it’s time to address the issue of disk once and for all. The expense of using disk to accommodate problems in the hope of buying extra investigation time is a quick fix that few organizations can sustain.

Imagine you had a friend that turned up right before something bad was going to happen and told you how to avoid it. Like if you don't attend to that looping job silently going about its business, the system in India will fall over and the downtime will cost the company hundreds of thousands of dollars in idle work hours. Yes, a friendly forewarning wouldn't be bad. We would suggest employing a job monitor – it's your friend on the inside.

IT Managers are not in the business of luck. They need to prepare for every disaster scenario, every contingency and ensure that even when every object, job and process is running 100% perfectly on the system, some other unforeseen network element doesn't swoop in and ruin all their efforts, just because it resides outside the parameters of the System i. After all, in a situation like this, people remember the one thing that went wrong – not the millions of things that went right – it's unfortunate, but that's life.

The size of today’s hard drives boggles the mind. Coupled with this surge in disk capacity is an explosion in file sizes. And multi-MB PowerPoints, MP3s and PDFs litter the hard drive. The problem is that drive I/O speed has not kept up the pace. As a result, it has developed into a serious bottleneck in system performance.
