STORAGE I VIRTUALISATION
Making cloud computing a reality
TREVOR DEARING Head of Datacentre Marketing, EMEA, Juniper Networks
QFabric™ - one logical switch, one fabric, one high-performance layer. By Trevor Dearing, Head of Datacentre Marketing, EMEA, Juniper Networks.
Cloud computing – the ability to deliver applications, software, platforms and infrastructure as services from a shared pool of resources - promises significant advantages. No longer forced to map applications to specific hardware, companies can reduce costs while accelerating product development, flexibility and productivity, speeding service delivery and increasing competitiveness.
Providing computer power on demand depends on being able to allocate and assign resources dynamically as they are needed. To meet this demand, great advances have been made in server
and storage technologies. However, one aspect of the data centre hasn’t kept pace: the network. That’s because traditional networks were never designed to handle dynamic data centre resources. Consequently, despite the advances in server and storage technology, organisations still have to plan virtual machines and storage very carefully to optimize performance.
Place the application one hop away from its storage and the latency could be three microseconds. Move the application to the other side of the data centre and latency could easily increase five-fold. That’s restricting enough, without all the
