This chapter provides an overview of the Sun StorageTek 6140 Array. It contains the following sections:


Product Overview

The Sun StorageTek 6140 Array is a high-performance, enterprise-class, full 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.


FIGURE 1-1 Sun StorageTek 6140 Array Product Overview


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.

Software Overview

The Sun StorageTek 6140 Array software is delivered on CD and consists of the tools described in the following topics:

You specify the functionality you require, and the CD installs the necessary software.

Management Software

The Sun StorageTek 6140 Array web-based management software is the primary interface for configuring and managing the array. The management software consists of a suite of tools that you install on an external management host, including the command-line interface (CLI). The management host must be a Sun workstation running the Solaris 8, 9, or 10 Operating System (OS).

The management software enables the storage administrator to manage the Sun StorageTek 6140 Array from any system with a web browser that is on the same network as the management host. For a list of supported browsers, see the Sun StorageTek 6140 Array Release Notes.

Remote CLI Client

You can also manage and configure storage for the Sun StorageTek 6140 Array using the remote CLI client. The CLI provides the same control and monitoring capability as the web browser, and it is scriptable for running frequently performed tasks.

The remote CLI client is available for Solaris OS and several other operating systems. See the Sun StorageTek 6140 Array Release Notes for a list of supported operating system platforms. For more information about the CLI commands, see the sscs man page.

Monitoring and Diagnostic Software

The Sun Storage Automated Diagnostic Environment is a monitoring and diagnostic tool for the array. You can configure the software to monitor on a 24-hour basis, collecting information that enhances the reliability, availability, and serviceability (RAS) of the Sun StorageTek 6140 Array. For additional information, see the Storage Automated Diagnostic Environment Enterprise Edition Release Notes.

The monitoring and diagnostic software can be accessed from a web browser or from the command line.

Data Host Software

The Sun StorageTek 6140 Array data host software controls the data path between the data host and the array.



Note - The management host can also be used as a data host.



The data host software consists of the following tools:



Note - The SAN Foundation software is embedded in the Solaris 10 OS.



Data host software enables Solaris 8, 9, and 10 workstations and other operating system platforms to communicate with the Sun StorageTek 6140 Array. For a list of supported operating system platforms, see the Sun StorageTek 6140 Array Release Notes.

Data host software for the Solaris OS is distributed on the Sun StorageTek 6140 Host Installation Software CD. See Chapter 8 for information about how to obtain the software for other operating systems from Sun's Download Center.
