Oracle® ZFS Storage Appliance Customer Service Manual
For ZS3-x, 7x20 Controllers, and DE2-24, Sun Disk Shelves
The Sun ZFS Storage 7320 consists of either a single storage controller or two storage controllers in a high availability cluster configuration. Both the single 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 18GB 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 http://www.oracle.com/us/products/servers-storage/storage/unified-storage/index.htmlhttp://www.oracle.com/us/products/servers-storage/storage/unified-storage/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 (1TB and 2TB SAS-2). The SAS-2 storage fabric supports a greater number of targets, greater bandwidth, higher reliability, and bigger scale than the SAS-1 fabric.
PCIe Risers: The storage controller contains three PCIe risers that are customer-replaceable units (CRUs) and are attached to the rear of the motherboard. Each riser supports one PCIe card.
Motherboard: The motherboard is a FRU and includes CPU modules, slots for 18 DIMMs, memory control subsystems, and the service processor (SP) subsystem. The SP subsystem controls the host power and monitors host system events (power and environmental). The SP controller draws power from the host 3.3V standby supply rail, which is available whenever the system is receiving AC input power, even when the appliance is turned off.
Power Distribution Board: The power distribution board is a FRU and distributes main 12V power from the power supplies to the rest of the storage controller. It is directly connected to the paddle board and to the motherboard through a bus bar and ribbon cable. It also supports a top cover interlock kill switch.
Paddle Board: The paddle board is a FRU and serves as the interconnect between the power distribution board and the fan power boards, hard drive backplane, and I/O board.
Fan Board: The fan boards are FRUs and carry power to the storage controller fan modules. In addition, they contain fan module status LEDs and transfer I2C data for the fan modules.
Disk Backplane: The hard drive backplane is a FRU and includes the connectors for the hard disk drives, as well as the interconnect for the I/O board, Power and Locator buttons, and system/component status LEDs. The storage controller has an eight-disk backplane. Each drive has an LED indicator for Power/Activity, Fault, and OK-to-Remove (not supported).
The following figure and legend identify the I/O components of the storage controller.

The storage controller motherboard has 18 slots in two groups that hold industry-standard DDR3 DIMM memory cards. All sockets must be occupied by either a filler or a DDR3 DIMM.

The following figure and legend identify the 7320 front panel drive locations. Two mirrored hard disk drives (HDDs) that store the operating system reside in slots 0 and 1. Up to four solid state drives (ReadZilla SSDs), which store the read cache, fill slots 2 through 5, in order. Slots 6 and 7 are empty and must contain drive fillers.
