Hardware 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.

Controller Tray

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.

TABLE 1-3 Controller Tray Ports and Components (Back)
Ports/Switches	Description
Host ports (Ch 1 - Ch4)	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).
Ethernet ports (1 and 2)	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.
Expansion ports (P1 and P2)	4- or 2-Gbit FC ports used to connect to the drive channel device and expansion trays.
Serial port	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.
Power supplies	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.
Battery backup compartments	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.

Common Array Manager Software

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.
