7320
Chassis Overview
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.

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.
Boards
The 7320 storage controller chassis has the following boards installed.

customer-replaceable units (CRUs) and are attached to the rear of the motherboard. Each
riser supports one PCIe card.
■
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.
