InfiniBand Software Overview |
This chapter includes the following topics:
The InfiniBand software is included in the Solaris 10 Operating System. FIGURE 4-1 shows a block diagram of the InfiniBand software stack which includes the following modules:
This library supports service providers written according to the uDAPL 1.2 specification. Sun provides default service provider modules to support the Tavor HCA driver.
The IPoIB driver implements the IETF IPoIB protocol and provides IPoIB services for all IB-HCA ports present in the system. This driver enables the standard Solaris TCP/IP stack to operate over Infiniband. The link layer driver encapsulates IPv4/6 packets, adds IB multicast support, extends ARP/ND address resolution, and changes the network stack to support link addresses greater than 6 bytes.
IBTF is the Solaris implementation of the InfiniBand Transport Layer (IBTL). IBTF consists of InfiniBand Device Manager (IBDM), InfiniBand Communications Manager (IBCM) and an InfiniBand Nexus driver. The Nexus driver along with IBDM creates and manages InfiniBand devices. The following devices are supported:
See ib(4) and ib(7D) for details.
IBCM provides a transport layer abstraction to IB clients to set up reliable connected channels along with service, multicast, and path lookup-related functionality. See ibcm(7D) for details.
IBMF is a complementary component to IBTF that enables IB clients to provide and access management services over the IB fabrics. It has two logical components. One component deals with sending and receiving management data to any type of management entity. The other component deals with sending and receiving management data to the Subnet Administrator (SA) only. Since every IB client needs to send and receive management data to the SA, IBMF provides functions that specifically handle the SA interaction.
The Tavor HCA driver controls the Tavor hardware and enables the transfer of data over the IB wire. This driver interfaces with the IBTF and provides an implementation of Channel Interfaces that are defined by IBTF. It also enables management applications and agents to access the IB fabric.
