Juniper Leapfrogs Cisco with QFabric Data Center

Network World — Juniper Networks (JNPR) today announced the results of $100 million in research and development: a new architecture for data center infrastructure called QFabric, formerly code-named Project Stratus.  The company says QFabric will boost data center throughput 10-fold and be able to scale 12 times larger than conventional architectures while cutting costs for infrastructure and operations. Analysts and beta users say they are impressed.

Four years in the making, QFabric promises to flatten data center architecture from two or three layers to one, drastically reducing the number of devices needed to build a data-center network.

The new architecture creates what is logically a single data center switch overseen by a management platform that gives one view of the fabric. QFabric is supported by three devices – the director management platform, the interconnect switching fabric and the node, which handles ingress and egress ports.

In making the announcement, the company showed three products to support QFabric – QF Director, QF Internconnect chassis and the QFX3500 node. 

The performance improvements that QFabric claims would put Juniper ahead of Cisco and HP (HPQ) for performance, says Rob Whiteley, an analyst with Forrester Research (FORR). Brocade comes the closest as a competitor for a data center fabric, he says, and it remains to be seen how the two will stack up. There are no full-fabric deployments of either yet, he says.

Even so, the promised improvements over current data center performance are worth considering even if a business has a data center built of another vendor’s gear, says Tom Nolle, president of CIMI Corp. consulting firm. “If you are a business refreshing data-center infrastructure in the next two or three years, you need to take a look at this,” Nolle says.

QFabric is the outcome of what Juniper has been calling Project Stratus, which was thought to be a faster conventional data center core switch. And in fact the QFX3500 does function as a conventional switch in its first iteration coming out later this quarter. But in Q3, a software upgrade will turn it into a node in the QFabric architecture, enabling it to make peer-to-peer routing decisions and rate limit to handle congestion as part of a distributed control plane.

Juniper’s founder and CTO Pradeep Sindhu says customers could migrate to the new fabric gradually even if they currently use another vendor’s gear. As current network equipment is refreshed, modules of QFabric could be deployed in tandem with legacy infrastructure. Because the Juniper line uses standard interfaces – Ethernet and Fibre Channel – it can interface with other products.
