This chapter provides an overview of the Sun StorageTek 6540 Array. It contains the following sections:
The Sun StorageTek 6540 Array is a high-performance, enterprise-class, full 4-Gigabit per second (Gb/s) Fibre Channel (FC) solution that combines outstanding performance with the highest reliability, availability, flexibility, and manageability.
The Sun StorageTek 6540 Array is mounted in a Sun Rack 1000-38 cabinet, which is fully prepared to be fitted with up to 11 expansion trays. The 6540 Array is scalable from a base configuration of one dual RAID controller tray and one expansion tray to a maximum configuration of one dual RAID controller tray and 11 expansion trays in one cabinet (see FIGURE 1-6) or up to 14 expansion trays across two cabinets.
The 6540 Array can be shipped as independent components or in a fully-racked and cabled environment. This section contains an overview of the Sun StorageTek 6540 Array hardware and software.
FIGURE 1-1 Sun StorageTek 6540 Array Product Overview
Each expansion tray can contain 5 to 16 disk drives, allowing the array to support up to 224 Fibre Channel (FC) or Serial Advanced Technology Attachment (SATA) disk drives.
This section describes the main components of the Sun StorageTek 6540 Array controller and expansion trays.
The Sun Rack 1000-38 cabinet is 39.4 inches (1000 mm) deep, 23.5 inches (59.7 cm) wide, and 74 inches (188 cm) tall. The cabinet has an empty weight of 360 pounds (163.3 kilograms) and a fully loaded weight of 1625 pounds (737 kilograms). The cabinet includes the Sun Power Distribution System (PDS), which provides a high-current, sequenced power system. The cabinet front and rear doors give you immediate access to hardware, cabling, and LEDs. The vertical cable management bracket and the cable management arms keep the cables organized for easy tracing and mobility.
The Sun PDS resides in the cabinet frame but does not occupy space that otherwise would be used for expansion trays. The PDS consists of two independently powered sequencers and two power outlet strips, each with 24 outlets. Therefore, it provides 48 outlets, in ten separate switched and two unswitched zones. Four 20-amp circuits are required to power the four power cords to the rack. Each circuit must provide 180 to 264 VAC at 47 to 63 Hz.
The 6540 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 FC connections to disk drives and trays, and provides RAID functionality and caching.
The controller tray has two power supply and fan compartments, and a battery backup compartment in which batteries are housed to retain cache memory in the event of a power failure. The backup batteries are accessed from a removable panel in the interconnection module.
TABLE 1-1 summarizes the controller tray configuration.
The SCSI RAID controllers communicate using the FC protocol to provide RAID and caching functionality. Each controller is hot-swappable. A battery that is housed in the controller tray interconnection module enables the controller to retain cache memory in the event of a power failure.
The power supplies provide hot-swappable, redundant power and cooling to the controller tray. Each power supply gets its power from an AC cord that is plugged into a RAID controller. The fans within the power supply are powered from the controller tray interconnection module. This regulates the environment so that the loss of AC or DC power from a single power supply does not affect the power to either set of fans.
The interconnection module is a hot-swappable unit that provides redundant connections between the two RAID controllers. If a power supply were to fail, the redundant connection through the interconnection module would continue to supply power to both controllers from the remaining power supply.
Although hot-swappable, the interconnection module itself is not redundant. If it is removed, the system will not go off line, but system performance will be impacted.
Write cache mirroring and access to redundant loops on the back end are accomplished through the interconnection module. If the interconnection module is removed, the system switches cache to write-through mode and fails over all volumes to one controller. That controller continues to have access to all disk drives and continues to service I/O using half of the backend loops.
The system remains in this mode until the interconnection module is replaced, at which time the system automatically reverts back to normal operations.
Battery backups supply power to the cache of both RAID controllers. A single controller tray battery pack is capable of supplying enough power to maintain data in cache for up to seven days.
Every system is shipped with redundant battery packs, which can support and maintain up to 4 Gbytes of cache memory per controller (8 Gbytes per system) for up to seven days, or up to 8 Gbytes of cache per controller (16 Gbytes per system) for up to three days. A single battery pack is capable of supporting and maintaining up to 2 Gbytes of cache per controller (4 Gbytes per system) for up to seven days.

Caution - On both the controller and expansion trays, the rear of the chassis has very sharp edges. |
An expansion tray (Common Storage Module 200 also known as CSM2) is directly attached by an FC loop to a controller tray and cannot operate independently. The expansion trays are connected to the RAID controllers in a controller tray using the drive port connections.
Should you need multiple expansion trays in a configuration, you can connect them together using FC cables. You can add up to 14 expansion trays (four sets of three or four expansion trays per set) to each controller tray.
Expansion trays are built from a 3 RU chassis and include power supplies and disk drives. Each expansion tray has two Fibre Channel Arbitrated Loop (FCAL) switch cards, one for each back-end loop.
In addition, each expansion tray is connected to the tray above and the tray below it by two FC cables. The FCAL switch performs trunking operations, which increases performance by opening multiple threads through the switch at one time.
Refer to Installing and Cabling Trays for details on expansion tray cabling.
TABLE 1-5 describes the expansion tray configuration.

The Sun StorageTek 6540 Array is managed by the Sun StorageTek Common Array Manager software. This software 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.
The web-based management software is the primary interface for configuring, managing, monitoring, and diagnosing the array. The management software consists of a suite of tools that you install on an external management host. The management host can be a Sun system running the Solaris 8, 9, or 10 Operating System (OS), or an x86 or x64 system running Solaris, or Windows 2000, 2003, or XP.
The management software enables the storage administrator to manage the 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 release notes.
The management software enables monitoring and diagnostic tasks on 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 array.
The management software records alerts and notifications, which you can monitor by displaying the log file. It also automates the transmission of alerts, which can be sent to an email address, to a pager, or to diagnostic software running on a management host on the network.
Finally, the management software enables you to run diagnostic tests to troubleshoot problems and access Service Advisor for instruction on replacing field-replaceable units (FRUs).
Field-replaceable units (FRUs) can be replaced by Sun field engineers or by Sun-trained customer administrators. To see a list of the hardware components that can be replaced at the customer site refer to Service Advisor in the Sun StorageTek Common Array Manager software.
The Service Advisor also provides information and procedures for replacing array components.
You can also manage and configure storage for the array using the remote command-line interface (CLI) client. The CLI provides the same control and monitoring capability as the web browser, and it is also scriptable for running frequently performed tasks.
The remote CLI client is available for Solaris operating system (OS) and several other operating systems. See the release notes for a list of supported operating system platforms. For more information about the CLI commands, see the sscs man page.
Remote management software is installed on the management host automatically.
The array data host software controls the data path between the data host and the array. The data host software consists of the following tools:
Data host software enables Solaris 8, Solaris 9, and Solaris 10 workstations and Windows XP and NT operating systems to communicate with the array.
You can obtain the data host software from Sun’s Download Center. Refer to the Sun StorageTek 6540 Array Release Notes (part number 819-6521-nn) for additional data host software information.
