Extending the Oracle Private Cloud Appliance by connecting and configuring additional storage can enhance the product by providing the disk space required for large repositories, for backup and recovery storage, and to provision virtual machines with virtual disks beyond the capacity already available on the appliance. This process does not require that the system is powered down, but cabling and configuration must match the Oracle Private Cloud Appliance requirements.
Different generations of the ZFS Storage Appliance have been delivered as part of Oracle Private Cloud Appliance, and the Controller Software continues to provide support for all previous generations. However, there are functional differences between the Oracle ZFS Storage Appliance ZS7-2, which is part of systems with an Ethernet-based network architecture, and the previous models of the ZFS Storage Appliance, which are part of systems with an InfiniBand-based network architecture.
There are options to extend the storage capacity of appliances with either type of network architecture, but the hardware involved and the required connectivity are different. For clarity, this chapter describes the addition of storage capacity separately for each network architecture.
