Mellanox Announces Virtual Protocol Interconnect With ConnectX™ Adapter Products

Leading Server and Storage Adapters Future Proof Data Center I/O Infrastructure

SANTA CLARA, CA, and YOKNEAM, ISRAEL – April 21, 2008 – Mellanox® Technologies, Ltd. (NASDAQ: MLNX; TASE: MLNX), a leading supplier of semiconductor-based, server and storage interconnect products, today announced the availability of Virtual Protocol Interconnect (VPI) in its industry-leading ConnectX™ server and storage adapter products. VPI enables I/O infrastructure flexibility and future-proofing for data centers and high-performance computing environments. VPI-enabled adapters facilitate any standard networking, clustering, storage, and management protocol to seamlessly operate over any converged network with the same software infrastructure. VPI also supports port auto-sensing of the fabric (InfiniBand, Ethernet or Data Center Ethernet) and configures the adapter in the appropriate mode easing deployments in both rack and blade environments.

“VPI is based on standard protocols and networking technologies, and disaggregates the Layer 2 network from the software communication protocols using networking, clustering, storage, virtualization and RDMA acceleration engines,” said Eyal Waldman, chairman, president and CEO of Mellanox Technologies. “VPI essentially future-proofs data center infrastructure by providing the freedom to select any communication protocol over any converged networking technology connecting server and storage resources to best optimize application performance, system power and overall efficiency – all with the same adapter solution. We are simplifying I/O system design for server and storage OEMs and making it easier for IT managers to deploy infrastructure that supports existing and emerging protocols.”

ConnectX adapter ICs and cards with VPI capabilities are already shipping in volume to first tier server and storage OEMs. These dual-port adapters can be configured to support VPI by a simple firmware upgrade that is expected to be available later in the second quarter with general availability in the third quarter.

VPI Addresses Key Data Center Connectivity Challenges

The demands on data center I/O connectivity continue to increase with the deployment of multi-core CPUs, virtualization, networked storage, clustered databases, and low-latency applications in financial services, health services, Web 2.0, and the commercial high performance computing sector. Multiple interconnect protocols and fabrics exist to provide the best-of-breed connectivity for certain applications, but the ideal solution is a flexible I/O adapter solution that can address all workloads. In addition, data centers are driving to replace multiple slower speed adapters with one higher speed adapter to save power, cost, cabling and complexity while not compromising lost functionality and performance.

VPI and ConnectX adapters provide leading server and storage I/O performance with flexibility to support the myriad of communication protocols and network fabrics over a single device, without sacrificing functionality when consolidating I/O. Specifically, VPI-enabled ConnectX adapters support:

  • Connectivity to 10, 20 and 40Gb/s InfiniBand switches, Ethernet switches, emerging Data Center Ethernet switches, InfiniBand to Ethernet and Fibre Channel Gateways, and Ethernet to Fibre Channel gateways
  • Fibre Channel over Ethernet and Fibre Channel over InfiniBand
  • A single firmware image for dual-port ConnectX adapters that supports auto-sensing of the Layer 2 port protocols and independent access to different convergence networks per port, especially useful for bladed server and storage environments
  • A unified application programming interface with access to communication protocols including: Networking (TCP, IP, UDP, sockets), Storage (NFS, CIFS, iSCSI, NFS-RDMA, SRP, iSER, Fibre Channel, Clustered Storage, FCoE and FCoIB), Clustering (MPI, DAPL, RDS, sockets), and Management (SNMP, SMI-S)
  • Communication protocol acceleration engines including: networking, storage, clustering, virtualization and RDMA with enhanced quality of service

See a Live Demonstration of VPI at Interop, Las Vegas April 29 – May 2

Come visit Mellanox at Booth #2307 during exhibition hours to see a live demonstration of VPI. Mellanox will demonstrate a server with a dual-port ConnectX VPI-enabled adapter connected to both an InfiniBand and an Ethernet network simultaneously. Data on the InfiniBand network flows through an InfiniBand to Fibre Channel gateway to storage disks using SRP (SCSI RDMA Protocol), while data on the Ethernet network flows through an Ethernet to Fibre Channel gateway using the FCoE (Fibre Channel over Ethernet) protocol at the same time.
