Oracle Private Cloud Appliance Review

On June 24, 2014, Oracle announced the latest addition to its Engineered System portfolio, the Virtual Compute Appliance (VCA). In 2015 the Virtual Compute Appliance was re-branded as the Private Cloud Appliance (PCA). Oracle markets the Private Cloud Appliance as:
“A Turnkey Converged Infrastructure Solution for Private Clouds and Virtually Any Application”
Oracle positions the Private Cloud Appliance against market leading converged infrastructure solutions that integrate the best-in-class compute, network, and storage technologies. The market leading converged infrastructure solutions offer the best-in-class Cisco compute and network components, VMware software, and EMC, or NetApp storage, including broad operating system, application, and VDI support.
The Private Cloud Appliance consist of a Sun Rack II 1242 base rack with 2 dedicated Sun Server X5-2 controllers, an Oracle ZS3-ES storage appliance, Oracle Virtual Networking, as well as Sun InfiniBand and Ethernet networking components, running Oracle Linux, Red Hat Linux, CentOS, Solaris x86, and Windows virtual machines. A single Private Cloud Appliance Rack can support up to 25 Sun Server X5-2 compute nodes. The Sun Server X5-2 compute nodes are sold separately.
The Private Cloud Appliance supports Trusted Partitions. Trusted Partitions allow Oracle software to be licensed at the virtual machine level instead of the physical processor core level. Trusted Partitions allow customers to right-size their Oracle software licensing with any Private Cloud Appliance configuration.
Note: Trusted partitions require that each virtual machine using a trusted partition to be managed by Oracle Enterprise Manager.
The Private Cloud Appliance utilizes both the Oracle VM for x86 server and management component. The server component is based on the open source hypervisor, named Oracle VM server. The Xen hypervisor is a type 1 hypervisor that installs directly on hardware. Oracle makes subtle changes to the original code that create a unique Xen distribution, which Oracle maintains and redistributes as Oracle VM server. Oracle VM server is designed to support the most demanding high I/O workloads like Oracle Databases
The default Oracle VM for x86 management component is a traditional Oracle WebLogic application, named Oracle VM Manager. Oracle VM Manager consists of two J2EE applications using a MySQL backend, with an Oracle Application Development Framework (ADF) administrative web portal. The Private Cloud Appliance uses the Oracle PCA Dashboard as the primary user interfaces, Oracle VM Manager, as well as Enterprise Manager for monitoring, and application management.

Key Features and Specifications

[c] Oracle VM supports two unique virtualization modes, paravirtualization mode (PVM mode) and hardware virtualization mode (HVM & PVHVM). Windows and Solaris x86 only support HVM and PVHVM modes, Linux supports PVM/HVM and PVHVM. Oracle VM Servers can support both PVM mode and HVM/PVHVM mode simultaneously on a single compute node.
Acquisition and Maintenance Costs
The Private Cloud Appliance consists of a base rack with two control nodes, and one ZFS Storage appliance. Compute nodes are sold separately one node at a time.
Note: The Private Cloud Appliance is sold by the Oracle hardware sales team, and partners.

  • Hardware installation and software configuration services are not included.
To run Oracle software on an Private Cloud Appliance, customers will need to purchase the following:
  • Oracle Database licenses
  • Oracle WebLogic licenses
  • Oracle Middleware licenses
  • Oracle application licenses

The Competition

Oracle positions the Private Cloud Appliance against market leading Converged Infrastructure solutions. Unlike the market leading Converged Infrastructure solutions that use widely adopted best-in-class compute, network, and storage technologies from industry leaders Cisco, EMC, NetApp, and VMware with broad application, and VDI support, the Private Cloud Appliance introduces a unique Oracle/Sun compute, network, storage, and virtualization stack with broad Oracle application and operating system support, without VDI. The Private Cloud Appliance is the ideal single Oracle hosting platform, but fails to compete against the market leading Converged Infrastructure solutions that target Non-Oracle environments.

The “Oracle on Oracle” approach resulted in an Oracle centric Converged Infrastructure solution that is missing key Non-Oracle functionally. For example, the Private Cloud Appliance adds significant value to Oracle software deployments leveraging functionality from products across Oracle’s hardware, storage, application, and management stack. The aforementioned Oracle  features add no value for Non-Oracle environments, thus limiting Private Cloud Appliance value to Oracle deployments.
