The data centers that today's IT professionals are asked to manage aren't just a tool, they are critical to their company's business. For many, the data center is the business itself. It has to deliver the best performance at the lowest possible total cost of ownership, and to scale as the business grows. As such, the majority of IT organizations have either already adopted, or are in the process of adopting virtualization technologies. This enables you to run different applications over the same servers, which maximizes server utilization and achieves a dramatic improvement in the total cost of ownership, elastic provisioning, and scalability.
However, the adoption of a virtualization architecture creates some very significant data center interconnect challenges to overcome. This is why the majority of IT organizations, if they haven't already, will be deploying advanced interconnect technologies to enable a faster, flatter and fully virtualized data center infrastructure. Using the right interconnect technology, connecting servers to servers and servers to storage, reduces cost while giving you the ability to support an increasingly virtualized and agile data center. This is exactly what Mellanox end-to-end interconnect solutions deliver.
Highest I/O Performance
Mellanox products and solutions are uniquely designed to address the Virtualized infrastructure challenges, delivering best in class and highest performance server and storage connectivity to various demanding markets and applications, providing true hardware-based I/O isolation and network convergence, with unmatched scalability and efficiency. Mellanox solutions are designed to simplify deployment and maintenance through automated monitoring and provisioning and seamless integration with the major cloud frameworks.

Hardware Based I/O Isolation
Mellanox ConnectX adapters and Mellanox switches provide high degree of traffic isolation in hardware, allowing true fabric convergence without compromising service quality and without taking additional CPU cycles for the I/O processing. Mellanox solutions provide end-to-end traffic and congestion isolation for fabric partitions, and granular control of allocated fabric resources.

Every ConnectX adapter can provide thousands of I/O channels (Queues) and more than a hundred virtual PCI (SR-IOV) devices, which can be assigned dynamically to form virtual NICs and virtual storage HBAs. The channels and virtualized I/O can be controlled by an advanced multi stage scheduler, controlling the bandwidth and priority per virtual NIC/HBA or a group of virtual I/O adapters. Thereby ensuring traffic streams are isolated, and that traffic is allocated and prioritized according to application and business needs.
Accelerating Storage Access
In addition to providing better network performance, ConnectX's RDMA capabilities can be used to accelerate hypervisor traffic such as storage access, VM migration, data and VM replication. The use of RDMA pushes the task of moving data from node-to-node to the ConnectX hardware, yielding much faster performance, lower latency/access-time, and lower CPU overhead.

In today's virtualized data center, I/O is the key bottleneck leading to degraded application performance and poor service levels. Furthermore, infrastructure consolidation and a cloud model mandate that I/O and network resources be partitioned, secured, and automated.
Mellanox products and solutions enable high-performance and an efficient cloud infrastructure. With Mellanox, users do not need to compromise their performance, application service level, security, or usability in virtualized environments. Mellanox provides the most cost effective cloud infrastructure.
