Access "Your next data center: Think flexible"

Published: 29 Oct 2012

Today's data centers are beginning to be structured around the separation of storage into storage area networks (SANs), with servers consolidated around the compute function. In tomorrow's data centers, servers will follow the modular path that storage has already started down, as we discussed the first part of this article last month (see "Towards the new data center," November 2002). What's missing from this picture is how storage and computing power will be connected and managed. There's more at stake than just questions of bandwidth and protocols: Data center designers will have to decide to what extent their infrastructures will be layered in tiers organized around price/performance. As for the networking aspect, Fibre Channel (FC), with its 2.12Gb/s bandwidth, has become the standard method for shuttling data between servers, switches and storage arrays within the enterprise SAN. But as server and storage densities increase, it's clear tomorrow's data centers will require a faster approach. "A high-speed interconnect is absolutely essential," says Fred... Access >>>
