Oracle Database Appliance X3-2
The ODA X3-2 is the second generation of the ODA devices. It has a lot of new features, as well as more capacity than
its predecessor. Figure

shows the appliance from the front.

Oracle Database Appliance X3-2
The Oracle Database Appliance X3-2 expands the capabilities found in the ODA V1 and packs a punch in terms
of hardware and storage capabilities. Oracle has taken a slightly different approach in terms of hardware architecture
for the X3-2. The server nodes and the storage rack are now two separate units that are connected together, and there
is an option to add an expansion storage rack to double the storage capacity of the appliance.
The X3-2 is more modular in structure than the version 1 appliance and it provides flexibility. Customers are able
to expand storage by adding an additional storage rack. They can create a storage rack and a server node rack in their
datacenters; however, we recommend installing the components together.
The X3-2 is still a 4U rack mountable unit, but it is divided into two individual 2U units. The server units are
1U each, and the storage unit is 2U as well. The expansion rack, if selected, will add another 2U to the system.
Table
1-4
lists the complete specifications for the X3-2 box, but the short story is that the box features Intel Xeon
E5-2690 processors, 256GB of memory, two 10GbE external copper connections, and two 10GbE internal network
interconnects. Also included are shared, serial-attached SCSI (SAS) disks. The internal disks are now 600GB, up from
the previous 500GB configuration that was in V1.
