7320 Chassis Overview - The Sun ZFS Storage 7320 consists of either a standalone storage controller or two storage controllers in a high availability cluster configuration. Both the standalone and clustered configuration supports one to six disk shelves.
The 7320 controller base configuration includes two CPUs, built-in 4 x 1Gb/s front-end GigE ports, redundant power supplies, NIC options for expanded front-end support, tape backup, InfiniBand, and dual port SAS HBA for storage expansion.
The CPUs are Intel Xeon 5600 series, 2.40GHz, 80W, with 4 core processors. The standard memory configuration is 96GB, 6 x 8GB DDR3-1333 low voltage (LV) DIMMs per CPU. Memory can be upgraded to 144GB using 9 x 8GB DDR3-1333 LV DIMMs per CPU (for a total of 18 x 8GB for two CPUs). Earlier versions of the 7320 controller included 24GB (base), 48GB, or 72GB memory options. The clustered configuration simply uses two servers and a cluster card in each server for a heartbeat connection between the servers.
All user-accessible storage is provided by one to six disk shelves that are external to the server(s). RAID functions are managed by software. Solid state SAS-1 drives (7320 SAS-2) are used for a high-performance write cache (known as LogZilla) or ZFS intent log (ZIL) devices, and are used in place of up to four of the 24 drives in a disk shelf. The remaining 20 drives are available for storage.
Refer to the product site at https://www.oracle.com/storage/nas/index.html for the most recent component specification.
The 7320 is a SAS-2 (Serial Attached SCSI 2.0) device that consists of an HBA, disk shelf, and disks. The SAS-2 storage fabric supports a greater number of targets, greater bandwidth, higher reliability, and bigger scale than the SAS-1 fabric. For information about supported disks and capacities, refer to the Oracle Systems Handbook.
Standalone Controller Configuration - The standalone controller base configuration is 96GB RAM, 2x2.4GHz Quad-Core processors, one external SAS HBA, and four 10/100/1000 Ethernet ports.
The following table describes base configurations for the 7320.

Following are the PCIe configuration options for a standalone controller. All PCIe cards are low profile and must be fitted with low-profile mounting brackets.

7320 Cluster Configurations - The 7320 cluster base configuration is 96GB RAM, 2x2.4GHz Quad-Core processors, one external SAS HBA, and four 10/100/1000 Ethernet ports, and a Cluster card. The Sun Storage 7420C Cluster Upgrade Kit (XOPT 594-4680-01) contains two cluster cards with cables for converting two 7320 or two 7420 controllers to a cluster.
The following options are available for clustered storage controllers.
