Data Center Overview

Mellanox’s networking solutions based on InfiniBand, Ethernet, or RoCE (RDMA over Converged Ethernet) provide the best price, performance, and power value proposition for network and storage I/O processing capabilities. Advanced data centers can utilize 25/40/50/100G InfiniBand or Ethernet, or RoCE to consolidate I/O to a single wire and enable IT managers to deliver significantly higher application service levels, while reducing CapEx and OpEx related to I/O infrastructures. Mellanox provides a large pool of deployment, manageability and performance tools with networking products for a myriad of software environments to fine tune solutions to customer requirements.


Increased density of virtual machines on a single system within a data center is driving more I/O connectivity per physical server. Multiple 1 Gigabit Ethernet NICs along with Fibre Channel HBAs are used in a single enterprise system for data exchange. Such hardware proliferation has increased I/O cost, convoluted cable management, and caused loss of I/O slots.  25GbE and higher networking solutions with higher speeds that can run multiple protocols simultaneously (RoCE, iSCSI, etc.) can deliver better performance with unmatched scalability and efficiency. This helps reduce costs while providing the ability to support an increasingly virtualized and agile data center.

Microsoft Based Solutions

Microsoft enhancements to Microsoft’s Server Message Block (SMB) 3.0. SMB included Storage Spaces Direct (S2D). S2D is a Microsoft Windows Server technology that implements the use of various high-speed RoCE methods to transfer large amounts of data with little CPU intervention. Mellanox RoCE doubles the performance in Storage Spaces Direct implementations, enabling significantly higher efficiency in Windows-based data centers.

Microsoft Azure Stack provides a hybrid cloud storage solution which utilizes the advantages of S2D and RoCE to provide for more efficient and faster access to data for enterprise applications, and provides more control of data than typical public could offering.

Data accessed over RDMA enables:

  • Increased throughput: leverages the full throughput of high speed networks in which the network adapters coordinate the transfer of large amounts of data at line speed.
  • Low latency: provides extremely fast responses to network requests, and, as a result, makes remote file storage feel as if it is directly attached block storage.
  • Low CPU utilization: uses fewer CPU cycles when transferring data over the network, which leaves more power available to server applications.

Scale-Out Databases

Mellanox high performance and low latency Ethernet and InfiniBand-based server adapters and switches provide fault-tolerant and unified connectivity between clustered database servers and native storage, allowing for very high efficiency of CPU and storage capacity usage. The result is 50% less hardware cost to achieve the same level of performance
