Controller Tasks - replace storage controller components
Disk Shelf Tasks - replace disk shelf components
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, 4 core processors. Standard memory configuration is 24GB, 3 x 4GB DDR3-1333 DR DIMMs and may be upgraded to 48GB using 6x4GB DDR3-1333 DR DIMMs per CPU or to 72GB using 9x4GB DDR3 DR DIMMs per CPU. The clustered configuration simply uses two servers and a cluster card in each server for a heartbeat connection between them.
All user-accessible storage is provided by one to four Sun Disk shelves external to the server(s). The RAID function is done by the software. Solid State 18GB SAS-1 drives (7320 SAS-2) which are used for high-performance write cache known as LogZilla or ZFS intent log (ZIL) devices, are in place of one to four of the 24 drives in the Disk Shelf, the remaining 20 drives are available for storage.
Refer to the http://www.sun.com/storage/disk_systems/unified_storage/7320/specs.xml for the most recent component specification.
The 7320 is a next-generation SAS-2 (Serial Attached SCSI 2.0) device that consists of a new HBA, new disk shelf, and new disks (1TB and 2TB SAS-2). The SAS-2 storage fabric supports greater number of targets, greater bandwidth, higher reliability and bigger scale.
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's 3.3V standby supply rail, which is available whenever the system is receiving AC input power, even when the system 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 - This board is FRUs and carries 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 I/O components of the storage controller are shown in the following figure and identified in the table.
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 Power Distribution/Fan Module components of the storage controller are shown in the following figure and identified in the table.
The following list shows the electrical specifications for the 7320. Note that the power dissipation numbers listed are the maximum rated power numbers for the power supply. The numbers are not a rating of the actual power consumption of the appliance.

The following graphic illustrates the front panel LEDs.
The table describes the LEDs.
The following graphic illustrates the 7320 front panel with drive locations described in the table. 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) that store the read cache fill slots 2 through 5, in order. Slots 6 and 7 are empty and must contain drive fillers.
Following is the complete list of replaceable power distribution, disk, and fan module components of the 7320 system. Note that power supplies, disks, and fan modules are hot-pluggable on the storage controller.
The single controller base configuration is 24GB RAM, 2x2.4GHz Quad-Core processors, one external SAS HBA, and four 10/100/1000 Ethernet ports.
Following are the PCIe configuration options for a single controller. All PCIe cards are low-profile, and must be fitted with low-profile mounting brackets.
The 7320 cluster base configuration is 24GB 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. Note that both storage controllers in a cluster must be configured identically with regard to card configurations and all optional NIC/HBA card configurations chosen for clustered storage controllers must be identical in both chassis.
The serial management connector (SERIAL MGT) is an RJ-45 connector and a terminal connection to the SP console.
The network management connector (NET MGT) is an RJ-45 connector on the motherboard and provides an alternate terminal interface to the SP console.
There are four RJ-45 Gigabit Ethernet connectors (NET0, NET1, NET2, NET3) located on the motherboard that operate at 10/100/1000 Mbit/sec. These network interfaces must be configured before use.
The 7320 single and cluster controller configurations allow a single chain of 1 to 4 Sun Disk Shelves. Any combination of disk-only and Logzilla-capable shelves may be combined within the chain in any order. The cabling configurations are unchanged. Half-populated shelf configurations are not supported.
