Gnodal Data Centre Switch OS Enhancements Enable 40GBE Cloud Backbone

Ethernet Switch Innovator Delivers Scalable, Congestion-Free Fabric for Virtualized IT Environments

LONDON--(Marketwire - Jan 29, 2013) - Today at Cloud Expo Europe, Bristol-based Gnodal Ltd, an innovator in 10/40GbE Ethernet switch fabrics, announced significant software enhancements to its adaptive, load-balancing fabric's operating system that provides private/hybrid cloud enterprise networks with improved monitoring capabilities via port mirroring, and optimized scalability and link utilization through multipath resolution.

The isotropic architecture in the Gnodal distributed, low-latency, Layer 2 core, removes typical constraints to cloud deployment. The Gnodal Network Operating System (GNOS) advantage becomes evident in a fabric-based environment, whereby multiple Gnodal GS-Series switches can be combined to create distributed core fabrics that support thousands of nodes. The Gnodal Ethernet Switch Fabric implements full-bisectional bandwidth capacity, while delivering the highest performance levels. The new release of GNOS also provides mechanisms to control a multi-switch environment as one switch with a single management pane, significantly simplifying network operations.

Further validating the GNOS cloud-backbone capability is RedPixie -- an emerging solutions provider in next-generation desktop, data centre infrastructure and on/off-premise cloud computing, which features the Gnodal Ethernet Fabric for connecting compute and storage nodes in its NimBrix platform. Leveraging Gnodal ultra-low-latency switches for its Ethernet fabric, RedPixie delivers a unified compute, storage and networking platform that eliminates the need for a SAN and overcomes conventional architectural limitations and costs.

NimBrix -- a highly disruptive, next-generation platform with an unmatched level of performance, scalability and flexibility -- combines the power of best-in-class compute, storage and networking technologies as requisite building blocks to deliver a world-class solution that transcends the performance of similar competitor offerings. For cloud service providers, NimBrix enables VDI 3.0, a turnkey experience delivering next-generation stateless desktops. The NimBrix architecture is scalable, supporting 1000s of nodes; elastic, allowing resources to be moved, removed and added on demand; can deliver high-performance with a linearly scalable architecture; and is fault tolerant, delivering advanced failure-handling capabilities with data mirroring, enabling virtual shelves with protection domains.

The new GNOS enhancements announced today reaffirm the transformative approach that Gnodal delivers in cloud efficiency through optimized services delivery and virtual infrastructure for sustained peak throughput and high device utilization. For example, relative to a VDI use case, application service providers utilising a very dense VM environment to serve a high number of desktops from as few physical servers as possible, are clearly promoting their technology to accelerate storage read/write capability, but also require a high-performance network to sustain optimal level I/O. While initial functional tests were projected to run at 1 Gbps, real-world results demanded the adoption of 10GbE ToR switches to gain maximum VM efficiency. As state-of-the-art server and storage technology continues to mature, the Gnodal GS-Series can easily support higher bandwidth, multi-chassis link aggregation group (MLAG) capability or Gnodal high-density 40GbE connections.

"Gnodal is uniquely positioned to redefine enterprise Ethernet networks to meet the objectives of next-generation data centre and cloud infrastructures that rely on flat and efficient, east-west, layer 2 Ethernet transport common to virtualized applications," said Atchison Frazer, Gnodal CMO. "The Gnodal Network Operating System underpins a tightly integrated Ethernet fabric; while other vendors talk about switch device functionality based on merchant silicon, only Gnodal Ethernet Fabric -- exclusively delivered via the Gnodal PETA-ASIC chip architecture -- delivers three key tenets of intelligent network fabrics: low latency, congestion avoidance, and multipath handling."

About Gnodal Network OS
The Gnodal Network Operating System, as a whole, delivers a scalable, congestion-free, deterministic and low-latency, data centre Ethernet fabric with single point management. This operating system is Gnodal software based on a Linux kernel, with Gnodal hardware drivers, and a number of protocol layers above it. A key differentiator between GNOS and legacy switching is that a large part of GNOS is embedded within the PETA-ASIC.

Additionally, GNOS uniquely offers distributed control, whereby each Gnodal PETA-ASIC actively participates in the system as a whole. This creates a system perspective to the fabric, in which the OS becomes hierarchical. Contrasted with conventional systems, such competitors are limited to having a functional OS that is multi-threaded, which, by necessity, must integrate with a number of third-party microprocessors through device drivers, causing each switch to act as an autonomous device with no awareness of the system as a whole, and thus not an infrastructure fabric.

About Gnodal
The Gnodal® ASIC Ethernet switch architecture features a congestion-aware performance and workload fabric that allows for ultra-low-latency transmission. It utilizes a dynamic, fully adaptive, load-balancing mechanism to arbitrate equitably a pre-emptive and deterministic pathway for large data sets, high-computational applications and massive storage demands prevalent in Cloud, HPDC and Big Data environments. The 72-port, 40GbE, "fabric-in-a-box" GS0072 solution extends Gnodal leadership in port density ToR solutions, and won the best-in-class award for networking at Interop 2012.

Gnodal high-performance network fabrics deliver industry leading Ethernet transport speed to reduce latency proactively. Gnodal highest port density 1U and 2U ToR switches are ideally suited for deployment within co-location environments and enterprise data centers. On ingress into GS-Series switching, the initial latency is sub-150 nanoseconds (store-and-forward) with each subsequent Gnodal switch added to the fabric incurring only 66 nanoseconds of additional latency (cut-through).
