Mellanox FlexBoot is a multiprotocol remote boot technology. FlexBoot supports remote Boot remote boot over Ethernet, Boot over Ethernet (BoE) or Boot over iSCSI (Bo-iSCSI). Using Mellanox Virtual Protocol Interconnect (VPI) technologies available in ConnectX® adapters, FlexBoot gives IT Managers' the choice to boot from a remote storage target (iSCSI target) or a LAN target (Ethernet Remote Boot Server) using a single ROM image on Mellanox ConnectX products.This technology is based on the Preboot Execution Environment (PXE) standard specification, and FlexBoot software is based on the open source iPXE project (see www.ipxe.org). For more information go to http://www.mellanox.com=> Products => Software => Ethernet Drivers => FlexBoot => Download.
4.4 RDMA over Converged Ethernet
ConnectX®-3 connected to an Ethernet fabric provides all of the basic NIC functionality plus RDMA over Converged Ethernet (RoCE). RoCE utilizes advances in Data Center Bridging (DCB) to enable efficient and low cost implementations of RDMA over Ethernet, supporting the entire breadth of RDMA and low latency features. This includes reliable connected service, datagram service, RDMA and send/receive semantics, atomic operations, user level multicast, user level I/O access, kernel bypass, and zero copy. This capability is enabled when using the Mellanox OFED or WinOF VPI drivers.
ConnectX®-3 EN with RoCE based network management is the same as that for any Ethernet and DCB-based network management, eliminating the need for IT managers to learn new technologies.
