7120 Hardware Overview

Use the information in this section as a preparation reference for servicing replaceable components of the 7120 system.

Refer to the following for procedural instructions:

Chassis Overview

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.sun.com/storage/disk_systems/unified_storage/7120/specs.xml for the most recent component specification.

The 7120 is a standalone controller that consists of a SAS-2 HBA providing disk shelf expansion, optional read and write flash accelerators, and 1TB and 2TB hard drives. 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 serial management connector (SER MGT) is an RJ-45 port and provides a terminal connection to the SP console. Image

The network management connector (NET MGT) is an RJ-45 port and provides an alternate terminal interface to the SP console. Image

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.

Electrical Specifications

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.

CPU and Memory

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. Image

Power Distribution, Fan Module and Disk Components
