connectivity between IB

network and SAN.

Allows InfiniBand-attached servers to utilize

block storage devices.

SRP

(SCSI RDMA

between cluster nodes for

Oracle RAC.

Allows application to take maximum

advantage of RDMA benefits through

flexible programming API. Requires

uDAPL

(Direct Access

Programming

Library)

Standard IP-based applications.

When used in conjunction with

Ethernet Gateway, allows

connectivity between IB

network and LAN.

Allows TCP/IP applications to run over the
