Storage

Private Cloud Appliance includes an Oracle ZFS Storage Appliance ZS9-2 as the base storage option, with the capability to expand storage within the rack as needed.

Oracle ZFS Storage Appliance ZS9-2

The Oracle ZFS Storage Appliance ZS9-2, which consists of two controller servers installed at the bottom of the appliance rack and disk shelf about halfway up, fulfills the role of 'system disk' for the entire appliance. It is crucial in providing storage space for the Private Cloud Appliance software.

The default disk shelf in the appliance has 100+ TB of customer usable storage for public object storage, customer compute images, and customer block storage.

The hardware configuration of the Oracle ZFS Storage Appliance ZS9-2 is as follows:

  • Two clustered storage controller heads

  • One fully populated disk chassis with twenty 18TB hard disks

  • Four cache disks installed in the disk shelf: 2x 200GB SSD and 2x 7.68TB SSD

  • Mirrored configuration, for optimum data protection

The storage appliance is connected to the management subnet and the storage subnet. Both heads form a cluster in active-active configuration to guarantee continuation of service in the event that one storage head should fail. The storage heads provide two IPs in the storage subnet: one for the default capacity storage pool, the other to access the optional performance (SSD) storage pool. Four management IP addresses are provided: one local to each controller head and one for each storage pool that follows the pool resources between controllers over takeover or failback events for convenient maintenance access. The primary mirrored capacity storage pool contains two projects, named PCA and private_ostore_project.

Additional Storage

You can optionally increase the storage in your system by adding disk shelves to a system flex bay. The available storage options for expansion are the Oracle Storage Drive Enclosure DE3-24C and the Oracle Storage Drive Enclosure DE3-24P.

The supported hardware configuration of the Oracle Storage Drive Enclosure DE3-24C is as follows:

  • Fully populated disk chassis with twenty 18TB hard disks

  • Four cache disks installed in the disk shelf: 2x 200GB SSD and 2x 7.68TB SSD

The supported hardware configuration of the Oracle Storage Drive Enclosure DE3-24P is as follows:

  • Twenty 7.68TB SSD

  • Two cache disks installed in the disk shelf: 2x 200GB SSD

  • Two drive bay fillers

Storage devices included in additional Oracle Storage Drive Enclosure DE3-24C enclosures are automatically added to the primary capacity storage pool, while devices included in Oracle Storage Drive Enclosure DE3-24P enclosures are automatically added to the optional high performance storage pool, after the enclosure is installed and cabled to the storage controller.

When connecting additional storage, refer to Oracle ZFS Storage ZS9-2 HE Clustered to Oracle Storage Drive Enclosure DE3-24 Disk Shelves (4 HBAs) for cabling instructions.
