passing through either device's CPU, without needing extensive buffering, and without calling to an
operating system kernel. RDMA can bring about a substantial reduction in CPU utilization on both the
application and database servers.
Oracle's 10G RDBMS product supports native SDP; however, Oracle products that use an earlier
version of the Oracle DB client can only utilize Transparent SDP. Both Oracle AS 9i and 10G Release
1 use the Oracle 9i DB client. Therefore, they can only use Transparent SDP. While this means that
Oracle AS cannot take advantage of asynchronous I/O or RDMA today, it still benefits from the
additional bandwidth and higher throughput provided by InfiniBand with Transparent SDP. Oracle AS
10G Release 2 will support native SDP.
Applications that connect to the database by using thin JDBC driver are also restricted to Transparent
SDP. Applications that use the OCI driver can use native SDP protocol provided the product support
SDP natively.
HP InfiniBand solution for Oracle Application Server
Solution overview
Many HP customers run J2EE applications in an Oracle Application Server environment using
standards-based HP ProLiant servers and HP StorageWorks Fibre Channel connectivity products.
With the addition of HP InfiniBand options for ProLiant servers, customers can implement a complete
HP-based Oracle Application Server solution using InfiniBand for the database connection.
Figure 1 depicts a sample configuration composed of the following components:
