The Sun Storage J4200/J4400 Array
The Sun Storage J4200 and J4400 arrays are general purpose, high-availability, and cost-effective serial attached SCSI (SAS) devices. The J4200 is a 2U, 12-disk tray and the J4400 is a 4U, 24-disk tray. Each supports SAS and Serial Advanced Technology Architecture (SATA) disk drives. The main components in each array are hot-swappable, including the SAS Interface Module (SIM) boards and drives, and the dual load-sharing power supplies and fans, providing a fault-tolerant environment with no single point of failure.
The J4200/J4400 arrays support 15K SAS drives and 7.2K SATA II drives. You can interconnect up to four J4200/J4400 trays, with up to 48 drives in interconnected J4200s and up to 96 drives in interconnected J4400s, all of which are designed to fit into a standard 19-inch cabinet.
This renders a raw storage capacity of 14.4 TB for SAS disks (300 GB per disk) or 36 TB for SATA II disks (750 GB per disk) for the J4200, and 28.8 TB for SAS disks (300 GB per disk) or 72 TB for SATA II disks (750 GB per disk) for the J4400. Refer to the Sun Storage J4200/J4400 Array Release Notes (820-3222-nn) for a complete listing of supported drives.
The J4200/J4400 array is available for Solaris, Linux, Windows, and VMware operating systems. You manage the array with the Sun StorageTek Common Array Manager (CAM) software.
|Note - If you are using the J4400 array as part of a Sun Storage 7000 Unified Storage System, you do not manage the J4400 array using the Sun StorageTek Common Array Manager (CAM). Instead, you manage the J4400 using the management software provided with the Unified Storage System.|
The trays can be installed into the following cabinets:
The J4200/J4400 array can be delivered fully assembled or packaged as individually ordered components that you install into the chassis. Customer-Replaceable Units provides a list of these components. All CRUs have a document describing installation instructions.

Following are descriptions for the Audible Alarm Silence Button and the System ID:
Disk drives for the Sun Storage J4200/J4400 array have several components: a hard disk, a hard disk carrier, the disk-release button, the disk ejector handle, and two status indicators (see FIGURE 1-8). You can access the disk drives from the front of the trays. The J4200/J4400 supports SAS disk drives or SATA II disk drives. A label on the handle indicates the drive type and its size and speed.
J4200s hold up to 12 disk drives, and four trays can be interconnected for a maximum of 48 disk drives in a chain; J4400s hold up to 24 disk drives, and four trays can be interconnected for a maximum of 96 disk drives in a chain. You must have at least two drives in either array.
Refer to the Sun Storage J4200/J4400 Array Release Notes for a complete listing of the supported drives.
Twelve or 24 removable disk drives are numbered from left to right, labeled from 0 on the lower left to 11 (J4200) or 23 (J4400) on the upper right.

Aside from a larger form factor, the J4200 and J4400 rear components are different. The J4200 has separate power supplies and fans, where the J4400 has an integrated power supplies and fan modules.
There are three mini-SAS connectors:

Two removable SAS Interface Module (SIM) boards. Each has a Host or SIM Link In port, a Host Out port, a SIM Link Out port, and an RJ-45 port for serial console access (reserved for Sun Customer Support personnel). The SIM boards are identified as SIM 0 (left) and SIM 1 (right).
The SIM board for each of the arrays includes the same components, indicators, and ports, however, the J4400 SIM board is larger than the J4200 SIM board, as required by the array’s form factor.
Each hot-swappable SIM board has one SAS inbound connector and two SAS outbound connectors, and one serial management port that is reserved for Sun Customer Support Personnel only.
FIGURE 1-11 and FIGURE 1-12 call out the individual components on the back of the SIM boards, and TABLE 1-3 provides descriptions of these components. TABLE 1-4 describes the SIM board component status indicators.

The J4200 has separate power supplies and fans, where the J4400 has an integrated power supply and fan module.
Each tray contains two hot-swappable, redundant power supplies. If one power supply is turned off or malfunctions, the other power supply maintains electrical power to the tray.
|Caution - The power supplies in this equipment can produce high energy hazards. Only instructed personnel with authorized access to this equipment can remove and replace modules in the system.|

The fans circulate air inside the tray by pulling it through the vents on the front of the assembly and pushing it out of the vents on the back of each fan.
Each J4200 array contains two hot-swappable fans for redundant cooling. Fan Module 0 is on the left and Fan Module 1 is on the right. If one fails, the remaining fan continues to provide sufficient cooling to operate the array. The remaining fan runs at a higher speed until the failed fan is replaced. Replace a failed fan as soon as possible.

The J4200/J4400 Array can be delivered fully assembled or packaged as individual components that you install into the chassis. All customer-replaceable units (CRUs) have a document describing the installation instructions in its shipping box. Additionally, the Common Array Manager (CAM) software has a Service Advisor application with wizards that guide you through CRU replacements.
The J4200/J4400 CRUs are designed for customers to install without turning off the power, with the exception of the Chassis CRU, which by necessity must be shut down and replaced by another chassis.
The following hardware components are designed to be customer installable:
The Sun StorageTek Common Array Manager (CAM) software suite provides management, monitoring, and service capabilities. The software has both a browser interface and a command-line interface (CLI).
The J4200/J4400 array requires a minimum version for CAM of 6.1.1. For detailed information about which versions of CAM to use with the array, refer to the Sun Storage J4200/J4400 Array Release Notes, part number 820-3222-xx, which is available at the following location:
For complete CAM documentation, go to the following location:
For more information about CAM, and to download the latest version, go to the following location:
|Note - If you are using the J4400 array as part of a Sun Storage 7000 Unified Storage System configuration, you do not use the CAM software suite. Instead, you manage the array using the management software provided with the Unified Storage System.|
The full management software is installed on a management workstation. The management software communicates with the J4000 arrays via a proxy agent that is installed on the data host. It provides:
The remote proxy agent enables communication, equivalent to in-band management, from the full management host to the array over an out-of-band-band IP network.
If the proxy is enabled, the full install of the Common Array Manager can manage the J4000 Family array remotely. To use the browser interface to manage the J4000 Family array, you sign into the IP address or host name of the full management host, sign into the software from the Java Web Console, and select the J4000 array. The remote proxy must be enabled while running the installation wizard or script.
The remote proxy should not be enabled for directly connected arrays.
The Sun StorageTek Common Array Manager software’s command-line interfaces provide the same control and monitoring capability as the Web browser and it is scriptable for running frequently performed tasks.
