Storage Hardware Installed in Private Cloud Appliance

ZFS Storage Appliance

The Oracle ZFS Storage Appliance fulfills the role of 'system disk' for the entire appliance. It is crucial in providing storage space for the Private Cloud Appliance software, configuration, services, backups, and so on. Depending on the base rack configuration, a different storage appliance model is installed.

• X9 and X10 configuration: Oracle ZFS Storage Appliance ZS9-2

• X11 configuration: Oracle ZFS Storage Appliance ZS11-2

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 ZFS Storage Appliance 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 best data protection

The ZFS 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 fails. The storage heads provide two IP addresses 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.

Optional Storage Expansion

You can optionally increase the storage in your system by adding disk shelves to a flex bay. If the base rack has no more space available, the expansion disk shelves can be installed in an additional rack cabinet. These storage expansion options are available:

Oracle Storage Drive Enclosure DE3-24C

The supported hardware configuration 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

Oracle Storage Drive Enclosure DE3-24P

The supported hardware configuration is as follows:

• Twenty 7.68TB SSD

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

• Two drive bay fillers

For cabling information when adding disk shelves to the ZFS Storage Appliance, see Oracle ZFS Storage ZS9-2 HE Clustered to Oracle Storage Drive Enclosure DE3-24 Disk Shelves (4 HBAs).

After the disk shelves are installed and cabled to the storage controllers, the new storage resources must be added to the existing storage pools. Storage devices included in additional DE3-24C shelves must be added to the primary capacity storage pool, while devices included in DE3-24P shelves must be added to the optional high performance storage pool.
