The Sun ZFS Storage 7120 is an enterprise-class two-socket rackmount x64 system powered by the Intel Xeon processor. It packs high performance and room for growth with four PCIe slots and 18 DIMM slots into a compact 2U footprint. Refer to the http://www.oracle.com/us/products/servers-storage/storage/unified-storage/index.html for the most recent component specification.
Refer to the Implementing Fibre Channel SAN Boot with Oracle's Sun ZFS Storage Appliance whitepaper at http://www.oracle.com/technetwork/articles/servers-storage-admin/fbsanboot-365291.html for details on FC SAN boot solutions using the Sun ZFS Storage 7120 Appliance.
The 7120 is a standalone controller that consists of an internal SAS-2 HBA providing disk shelf expansion, write flash acceleration, and 11 x 300GB 15K, 600GB 15K, 1TB 7.2K, 2TB 7.2K, or 3TB 7.2K hard drive storage. The SAS-2 storage fabric supports greater number of targets, greater bandwidth, higher reliability and bigger scale.
The 2U chassis form factor dimensions are as follows:
The following figure shows the front panel and the table describes the drive locations. The Logzilla 3.5" SSD belongs in slot 3 and is not supported in controllers configured with the internal Sun Aura flash HBA Logzilla.
The following figure shows the rear panel. Note that optional Sun Dual Port 40Gb/sec 4x Infiniband QDR HCAdapter PCIe cards (375-3606-01) may be located in slots 1, 2, or 3. Note that 375-3606-01 HCA expansion cards are not supported in the 10Gb network configurations.
The serial management connector (SER MGT) is an RJ-45 port and provides a terminal connection to the SP console.
The network management connector (NET MGT) is an RJ-45 port and provides an alternate terminal interface to the SP console.
There are four RJ-45 Gigabit Ethernet ports (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 following list shows the electrical specifications for the 7120. 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 chassis has the following boards installed. Field-replaceable units (FRU) should only be replaced by trained Oracle service technicians.
PCIe Risers - Each riser supports two PCIe cards that are customer-replaceable. There are two risers per system, each attached to the rear of the motherboard.
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 Connector Break Out Board, and to the motherboard through a bus bar and ribbon cable. It also supports a top cover interlock kill switch. The power supplies connect directly to the power distribution board.
Connector Break Out Board - The Connector Break Out Board is FRU and serves as the interconnect between the power distribution board and the fan power boards, storage drive backplane, and I/O board. It also contains the top-cover interlock "kill" switch.
Fan Power Boards - The two fan power boards are FRUs and carry power to the system fan modules. In addition, they contain fan module status LEDs and transfer I2C data for the fan modules.
Storage Drive Backplane - The storage drive backplane is a FRU and includes the connectors for the storage drives, as well as the interconnect for the I/O board, Power and Locator buttons, and system/component status LEDs. The system has a 12-disk backplane. Each drive has an LED indicator for Power/Activity, Fault, and Locate.
The storage controller's internal cables are shown in the following figure and table. Note that the rear boot drives are not depicted in this illustration.
The 7120 motherboard has 18 slots in two groups that hold industry-standard DDR3 DIMMs. The 7120 CPU and memory should only be replaced by field service professionals. All sockets must be occupied by either a filler or a DDR3 DIMM. All DDR3 DIMMs must be identical. DIMMs are pre-installed in P0 slots D1, D2, D4, D5, D7, and D8.
The fan modules and LEDs are shown in the following illustration.
The power distribution and associated components are shown in the following illustration and described in the table.
The 7120 standalone configurations allow a single chain of 1 or 2 Sun Disk Shelves. Write-optimized (Logzilla) SSDs are not supported in the expansion storage for the 7120. The disk shelves must be fully populated with 24 HDDs. Half-populated shelf configurations are not supported.
