Dell Integrated Systems for Oracle Business Analytics (DISOBA) – Owner’s Guide 1.0
4 DISOBA Software Configuration
This section describes all the software configuration that the following hardware
components in the DISOD ships with:
 DAAD Storage Array Configuration
 OBIEE Server (R730) Configuration
 Database Nodes (R920s) Configuration
 Management Server (R320) Configuration
4.1 DAAD Storage Array Configuration
This section provides the details of the DAAD storage array that is configured using Dell
and Fusion-io’s best practices for Oracle Database.
Each DAAD storage array node has four 3.0TB ioMemory cards. With ION HA clustering
enabled, the four ioMemory cards (ioDrive1-4) of one DAAD storage array are mirrored
with the four in the other node in the HA cluster, as shown in Figure 13.

Mirroring between the ioMemory cards between the DAAD Storage Array
nodes
A storage pool is created for each ioMemory card, and then two volumes are created for
each storage pool. Each volume has a primary storage node and a secondary node. As
shown in Figure 14, volumes v_a1, v_b1, v_c1 and v_d1 use storage node 1 (fcion1a)
as the primary node and volumes v_a2, v_b2, v_c2 and v_d2 use storage node 2
(fcion1b) as the primary node to present the volumes to the database nodes. When the
database servers update data on the volumes, updates load onto the primary nodes and
are then replicated to their mirrored volumes on the secondary node. This design allows
