Item	Quantity	Description
A	2	Oracle ZFS Storage Appliance ZS7-2 controller server
B	2	Oracle Server X8-2, used as management nodes
C	2-25	Oracle Server X8-2, used as virtualization compute nodes (Due to the power requirements of the Oracle Server X8-2, if the appliance is equipped with 22kVA PDUs, the maximum number of compute nodes is 22. With 15KVA PDUs the maximum is 13 compute nodes.)
D	2	Cisco Nexus 9336C-FX2 Switch, used as leaf/data switches
E	1	Oracle ZFS Storage Appliance ZS7-2 disk shelf
F	1	Cisco Nexus 9348GC-FXP Switch
G	2	Cisco Nexus 9336C-FX2 Switch, used as spine switches

At the software level, Oracle Private Cloud Appliance leverages the virtualization technology of Oracle VM and Oracle Software Defined Networking. Management, including updates, of the underlying hardware and software is orchestrated and largely automated by the Oracle Private Cloud Appliance controller software.
