1 Solution Overview

Deploying and maintaining a private or public cloud is a complex task – with various vendors

developing tools to address the different aspects of the cloud infrastructure, management,

automation, and security. These tools tend to be expensive and create integration challenges

for customers when they combine parts from different vendors. Traditional offerings suggest

deploying multiple network and storage adapters to run management, storage, services, and

tenant networks. These also require multiple switches, cabling, and management

infrastructure, which increases both up front and maintenance costs.

Other, more advanced offerings provide a unified adapter and first level Top-of-Rack (ToR)

switch, but still run multiple and independent core fabrics. Such offerings tend to suffer from

low throughput because they do not provide the aggregate capacity required at the edge or in

the core; and because they deliver poor application performance due to network congestion

and lack of proper traffic isolation.

Several open source “cloud operating system” initiatives have been introduced to the market,

but none has gained sufficient momentum to succeed. Recently OpenStack has managed to

establish itself as the leading open source cloud operating system, with wide support from

major system vendors, OS vendors, and service providers. OpenStack allows central

management and provisioning of compute, networking, and storage resources, with

integration and adaptation layers allowing vendors and/or users to provide their own plug-ins

and enhancements.

Red Hat built an industry leading certification program for their OpenStack platform. By

achieving this technology certification, vendors can assure customers that their solutions have

been validated with Red Hat OpenStack technology. Mellanox is the first InfiniBand and

Ethernet adapter vendor to be listed on the Red Hat Certified Solution Marketplace, a directory

of technologies and products which have been certified by Red Hat and are designed to

optimize all offerings that include Red Hat OpenStack. Mellanox is listed in the Red Hat

marketplace as a certified Hardware partner for Networking (Neutron) and Block Storage

(Cinder) services. This ensures that Mellanox ConnectX-3 InfiniBand and Ethernet adapter

was tested, certified, and now supported with Red Hat OpenStack technology.

Red Hat Enterprise Linux OpenStack Platform 4.0 delivers an integrated foundation to create,

deploy, and scale a secure and reliable public or private OpenStack cloud. Red Hat Enterprise

OpenStack Platform 4.0 combines the world’s leading enterprise Linux and the

fastest-growing cloud infrastructure to give you the agility to scale and quickly meet customer

demands without compromising on availability, security, or performance.

Mellanox Technologies offers seamless integration between InfiniBand and Ethernet

interconnect and OpenStack services and provides unique functionality that includes

application and storage acceleration, network provisioning, automation, hardware-based

security, and isolation. Furthermore, using Mellanox interconnect products allows cloud

providers to save significant capital and operational expenses through network and I/O

consolidation and by increasing the number of virtual machines (VMs) per server.

Mellanox provides a variety of network interface cards (NICs) supporting one or two ports of

10GbE, 40GbE, or 56Gb/s InfiniBand. These adapters simultaneously run management,
