BlackDiamond X series switches offer enterprise and cloud data center networks the highest throughput performance in the industry.

The BlackDiamond X series switches deliver the highest density of 10 GbE and 40 GbE for the ultimate flexibility in building enterprise core networks and cloud data centers. With its high scalability, the BlackDiamond X series switches offer 1.28 Tbps slot capacity, more than 20 Tbps switching fabric capacity, and up to 768 ports of 10 GbE or 192 ports of 40 GbE per chassis. All of this is available in a very small footprint of one third rack size (14.5 RU).

Data centers today demand highly virtualized, converged, and scalable infrastructure. Multi-tenancy and cloud computing are driving the need for simplicity and cost efficiency from the network fabric, along with a need for expandability, high performance, and service up-time. The Extreme Networks Open Fabric solution, led by its flagship BlackDiamond X8 platform, provides seamless any-to-any connectivity through a simple, scalable, and centrally orchestrated network.

Designed for cloud-scale requirements of data centers, high-performance computing (HPC), and Internet exchange points (IXP), the BlackDiamond X8 provides a low-latency, high-performance switch fabric with high-density wire-speed 10GbE, 40GbE, and 100GbE connectivity for edge-to-core applications, all in a compact footprint using only one-third of a standard rack. As a “fabric-in-a-box” solution, the BlackDiamond X8 eliminates expensive multi-tier architectures and the challenges of inter-device connectivity, uplink bandwidth, and latency. The BlackDiamond X8 also leverages a low-power design ideal for green operations and high degrees of energy efficiency, resulting in lower total cost of ownership (TCO).

"Cloud-Scale" Switching

The BlackDiamond X8 provides either 10.24 or 20.48Tbps total switching capacity for traffic growth while supporting 384 1GbE / 768 10GbE / 192 40GbE, or 32 100GbE wire-speed ports in a single chassis. This translates into 1,152 1GbE / 2,304 10GbE / 576 40GbE, or 96 100GbE ports in a single rack or any combination of those. The BlackDiamond X8 design leverages an orthogonal direct mating system between the interface and switch fabric modules, eliminating the performance bottlenecks of backplane or mid-plane designs. The BlackDiamond X8 offers up to 1.28Tbps unidirectional capacity per slot with current switch fabric modules, with an architecture extensible to support even higher capacity switch fabric modules in the future.

High-Density, High-Scale Server Virtualization

The BlackDiamond X8, powered by the ExtremeXOS® modular operating system, provides a scalable foundation for virtualized applications. By connecting up to 128000 (1 million in future) Virtual Machines (VMs) per system, spread across as many as 768 connected server ports per chassis, the BlackDiamond X8 enables a highly virtualized network infrastructure.

ExtremeXOS runs on a high-performance control plane and helps simplify network deployment and operation through VM-ready capabilities such as ExtremeXOS Network Virtualization (XNV™) and Extreme Networks Direct Attach™. XNV allows auto-configuration of Virtual Port Profiles (VPP) to automatically detect and provision network policies in a virtualized data center in a hypervisor agnostic manner, providing simplicity in managing VM mobility in data-centers. If a VM is moved from one physical server to the other, associated port policies on the connecting switch port are automatically moved. Direct Attach™ eliminates the virtual switch layer, simplifying the network and improving performance.

Several other virtualization features, such as Multi-Chassis Link Aggregation (M-LAG), Port Isolation and Transparent Interconnection of Lots of Links (TRILL), enable the design of flatter network fabrics for large scale virtualized and multi-tenant data centers, eliminating the need for dedicated networks and the complex Spanning Tree Protocol (STP).

Reliable Delivery of Converged Storage Traffic

The BlackDiamond X8 is an optimal solution for high-throughput storage applications, synchronous replication, and disaster recovery within data center and HPC environments. The BlackDiamond X8 supports IEEE Data Center Bridging (DCBx) for reliable delivery of IP storage (iSCSI, NFS, CIFS) traffic over a single converged network. With IEEE compliant lossless Ethernet implementation of Priority Flow Control (PFC) and Enhanced Transmission Selection (ETS), storage traffic can be prioritized, queued and bandwidth guaranteed.

The BlackDiamond X8 also supports transit Fiber Channel over Ethernet (FCoE) for carrying converged fiber channel storage traffic. In converged networks, TRILL enables the building of flat and efficient networks for storage traffic while eliminating complications resulting from STP. With BlackDiamond X8, storage nodes can be connected using wire-speed 10GbE or 40GbE to provide a highly reliable yet flexible and cost-effective network to provision reliable storage services.

Low Latency for Faster Response Time

For low-latency applications such as High Performance Computing (HPC) or High Frequency Trading (HFT), the BlackDiamond X8 provides only 2.3 microsecond port-to-port latency from any IO module to any IO module with a single-tier "fabric in a box" design, and under 3 microsecond latency with a two-tier "open fabric" architecture using Extreme Networks Summit® X770 series Top-of-Rack switch with the BlackDiamond X8. The latency is sub-microsecond between the ports on the same IO module.

With the growth of mobile devices, an increasing number of applications are hosted in data centers, resulting in increased east-west and north-south traffic. Though total latency is a result of the compute, storage and transmission latencies, the BlackDiamond X8 can deliver the benefits of lower network latency to improve customer experiences and overall application response time.

Orchestration Through Software Defined Networking

Software Defined Networking (SDN) is revolutionizing the way networks are designed and operated. SDN helps in virtualization, visibility, optimization and orchestration for better handling of the network, compute and storage from a single and granular command and control perspective.

The BlackDiamond X8 supports standards-based Open Flow to work with third party and open source SDN controllers and provides a complete SDN solution. The BlackDiamond X8 enables SDN by providing a programmable control path and a scalable fabric that can be programmed in an efficient manner. Additionally, the BlackDiamond X8 supports the Open Stack Neutron plugin for cloud level orchestration.

The BlackDiamond X8 can be leveraged in hybrid networks for simultaneous SDN and non-SDN based deployments. Off-theshelf or home-grown SDN based applications can be used for network control, traffic engineering, quality of service, SLA management, monitoring, analytics, virtualization and other advanced implementations.

High Scale Enterprise Routing

With future availability, the BlackDiamond X8 will support two types of interface modules: the existing Non-XL modules for high-density, low-latency moderate-scale edge and core applications, and the future XL modules for the high-scale core or border applications. By supporting up to one million Layer 2/ Layer 3 entries on its 40GbE and 100GbE XL-series interface modules (future availability), the BlackDiamond X8 eliminates the need for high cost traditional routers in the data center core. The XL and non-XL modules can be deployed together within the same core switch without impacting one another - not only collapsing tiers to simplify the network, but also reducing build-out and maintenance costs.

XL-series modules can also be deployed for the high-scale edge applications where a large number of host routes or access control lists (ACL) are required, such as managed hosting and cloud. The 40GbE and 100GbE module can also be used to break down the ports into multiple 10GbE ports for high-density, highscale edge connectivity.

Inter-Data Center Connectivity

The BlackDiamond X8 is designed with combined data center core and border connectivity in mind. For this reason, BlackDiamond X8 10GbE SFP+ and 100GbE CFP2 modules provide long-range connectivity for up to 80 and 10 kilometers respectively using a range of optics. In future when supported, the BlackDiamond X8 XL-series modules will offer more capacity to store large scale internet routing tables and MPLS forwarding entries, eliminating the need for expensive routers.

The BlackDiamond X8 can provide VM mobility between the active/active data centers using MPLS Virtual Private LAN System (VPLS). The Virtual Router (VR) support enables logical partitioning of the BlackDiamond X8 core into multiple instances that can be mapped into multiple VPLS pseudo-wires for complete isolation and integrity of tenant traffic end-to-end.

High Availability for Service Assurance

Today's mission critical data centers and service provider networks cannot afford service blackouts and upset customers. Designed for Tier-3 and 4 data centers and service providers, the BlackDiamond X8 prevents any single point of failure at the hardware level through isolated control and data planes, fully redundant 1+1 management modules, N+1 redundant switching fabric, and N+1 redundant fans. For the power system, the BlackDiamond X8 offers N+1 power supply level and N+N power grid level redundancy.

At the software level, modular ExtremeXOS software increases network availability by monitoring independent processes in real time. If any of these processes become unresponsive or stop running they can be automatically restarted without impacting other processes. The BlackDiamond X8 supports a set of high availability features, including In-Service Software Upgrade (ISSU), Multi-Chassis Link Aggregation (M-LAG) and Ethernet.

Lower Operating Costs, Better Business Margins

The BlackDiamond X8 is designed for power cooling and space efficiency. Power consumption as low as 5.6 Watts per 10GbE port is enabled through an obstruction-less orthogonal design, and variable speed fans that assist in lower heat dissipation and more efficient use of data center cooling resources. This results in lower utility bills to operate the network. The very high density design of the BlackDiamond reduces space and rack requirements, providing fast return on investment per RU. By leveraging CFP2 optical technology, the 100GbE module is not only denser than legacy CFP-based solutions, but also uses less than half as much power. The BlackDiamond X8 also supports CLI migration utilities to reduce the learning curve of technical personnel and save cost. Overall, the BlackDiamond X8 results in lower TCO compared to other switches in its class.
