This chapter provides an overview of the Sun StorageTek 6140 Array. It contains the following sections:
The Sun StorageTek 6140 Array is a high-performance, enterprise-class, full 2 or 4 Gigabit per second (Gb/s) Fibre Channel solution that combines outstanding performance with the highest reliability, availability, flexibility, and manageability.
The Sun StorageTek 6140 Array is modular, rackmountable and scalable from a single dual-controller tray (1x1) configuration to a maximum configuration of 1x7 with six additional expansion trays behind one controller tray (FIGURE 1-1).
This section contains an overview of the Sun StorageTek 6140 Array hardware and software.

Overview
The Sun StorageTek 6140 Array is a modular storage device that can scale from one controller tray to an array with a maximum of seven trays, consisting of one controller tray and six expansion trays. Each controller or expansion tray can contain 5 to 16 disk drives, allowing the array to support up to 112 disk drives.
The StorageTek 6140 Array can be installed in the Sun Rack 900 /1000 or Sun StorEdge Expansion cabinets.
This section describes the main components of the Sun StorageTek 6140 Array controller and expansion trays.
A controller tray contains two redundant array of independent disks (RAID) controllers, which operate independently and provide failover capability for the data and management paths. The controller tray is configured for Fibre Channel (FC) or Serial Advanced Technology Attachment (SATA) II disk drives and provides RAID functionality, caching, and disk storage.
TABLE 1-1 describes the controller tray configuration.
FIGURE 1-2 shows the LEDs and components at the front of the controller tray.

Note - A tray LED icon may not be visible unless the LED is illuminated. |
FIGURE 1-3 shows the ports and components at the back of the controller tray.
FIGURE 1-3 Controller Tray Port and Components (Back View)
TABLE 1-3 describes the ports and components at the back of the controller tray.
Four 4-, 2-, or 1-Gbit/second FC Small Form-factor Plug-in (SFP) ports. Ch4 host port is reserved for remote replication (if remote replication is licensed and activated; otherwise, Ch4 is available for host port use). Note: 1 Gbit/second operation is supported for legacy equipment only). |
|
RJ-45 Ethernet ports. Ethernet port 1 is used for out-of-band management of the RAID controller. An internal Ethernet device provides standard 10 Mbits/second and 100 Mbits/second full-duplex connectivity. Ethernet port 2 has limited functionality and is reserved for future use. |
|
4- or 2-Gbit FC ports used to connect to the drive channel device and expansion trays. |
|
Port that allows terminal access for display or configuration of the IP addresses for the array, and for recovery of a lost password for the array. |
|
For each controller tray, two power supplies with battery backup. The power supplies provide redundant power to both controllers. If one power supply fails, both controllers are powered by the remaining power supply. |
|
For each controller, a battery backup to maintain the integrity of the controller’s data cache for up to 72 hours in the event of power loss to both controller tray power supplies. See Battery Backup Compartments for more information on the battery backup compartments. |

Tray LEDs and Indicators (Back View)
TABLE 1-4 describes the LEDs and indicators at the back of the controller tray.
|
On indicates that the correct DC power is being output from the controller power supply. |
|
Steady amber indicates that the power supply requires service. Off indicates that the power supply does not require service. |
|
Steady blue indicates that service action can be taken on the power supply without adverse consequences. Off indicates that the power supply is engaged and service action should not be implemented. |
|
On indicates that AC power is being supplied to the controller power supply. |
Seven-segment readouts indicate the ID of the tray and fault diagnostic status codes. See LED Status Codes for definitions of the codes. |
|
|
Steady green indicates that data is in the cache. Off indicates that all data has been written to disk and the cache is empty. |
|
Steady amber indicates that the controller requires service. Off indicates that the controller does not require service. |
|
Steady blue indicates that service action can be taken on the controller without adverse consequences. Off indicates that the controller is engaged and service action should not be implemented. |
|
The combined display indicates the host port link rate for the tray: |
|
The combined display indicates the expansion port link rate for the tray: |
|
Steady amber indicates that no valid device is detected and that the drive port is bypassed. Off indicates that there is no small form factor plug-in (SFP) transceiver installed or that the port is enabled. |
Ethernet
Link Activity
|
Steady green indicates that there is an active connection. Off indicates that there is not an active connection. |
Ethernet
Link Speed
|
Steady green indicates that the there is a 100BaseTX connection to the port. Off (when Ethernet Status LED is on) indicates that there is a 10BaseT connection to the Ethernet port. |
The controller tray has a battery backup compartment for each controller in which a battery is housed for power backup.
FIGURE 1-5 shows the location of the battery compartments on the controller and identifies the LEDs on the compartment.

TABLE 1-5 describes the LEDs on the back of each battery backup compartment.
The expansion tray provides from 5 to 16 additional FC or Serial Advanced Technology Attachment (SATA) II drives. An expansion tray is cabled directly to a controller tray and cannot operate independently.
TABLE 1-6 describes the expansion tray configuration. Check the latest Sun StorageTek 6140 Array Release Notes to verify the current supported configuration.

H8 - SFP(s) Present in Currently Unsupported Slot (2A or 2B)
The Sun StorageTek 6140 Array is managed by the Sun StorageTek Common Array Manager software. The Common Array Manager provides web browser-based management and configuration from an external management host, data host software that controls the data path between the data host and the array, and a remote CLI client that provides the same control and monitoring capability as the web browser, and is scriptable for running frequently performed tasks.
For information about installing the Common Array Manager software and configuring and managing the array, see the Sun StorageTek Common Array Manager Software Installation Guide.
Before you begin to install the array, you must do the following:
The following checklist (TABLE 1-9) outlines all of the tasks required for installing the Sun StorageTek 6140 Array hardware and tells you where you can find detailed procedures. To ensure a successful installation, perform the tasks in the order in which they are presented.
