This appendix provides information for the Sun StorageTek 6540 Array as a standalone system and a factory default system that is fully racked and cabled.
Use the procedures in this appendix to install trays in a cabinet. The number of trays you need to install depends on your overall storage requirements. You can install one controller tray and up to 14 expansion trays. The maximum configuration would require a second cabinet, as the cabinets can hold 11 trays only.
This chapter describes the process of installing the Sun StorageTek 6540 Array. It contains the following sections:
The installation procedures in the following section requires the following items:
Use the following procedures to prepare for installation:
Only Sun Service should install expansion modules with data. See the Sun StorageTek Common Array Manager 5.1.3 or higher for more information about supported expansion modules by array.
When you add a new CSM200 expansion module to an existing array in a production or active environment, it is best practice to cable and add the trays while the RAID controller module is powered on, in order to avoid a variety of issues including those listed below.
Before connecting any replacement drive or additional expansion module to an existing functioning array, it is best practice to contact Sun Microsystems Support Services. One reason for this is to avoid issues related to DACstore, the configuration and status database maintained by the array firmware, that stores its information on each of the disk drives.
Contact Sun Microsystems Support Services promptly upon experiencing any of the following symptoms:
Use the universal rail kit to mount the Sun StorageTek 6540 expansion trays in any of the following cabinets:
Unpack the universal rail kit and check the contents.
The universal rail kit (part number 594-2489-02) contains the following items:
| Note - Typically, the main and extender pieces of both the left and right rails are shipped pre-assembled. |
The mounting hardware required for each rack or cabinet type is listed in the following table:
*For cabinet installations with M5 or 12-24 threaded cabinet rails, the following screws are not supplied. You must acquire these to match the threading requirements of your cabinet rails:
**For cabinet installations with unthreaded cabinet rails, the following hardware is not supplied. You must acquire these to match the requirements of your cabinet rails:
Use the #2 Phillips screwdriver to loosen the two rail adjustment screws on each rail to allow adjustment of each rail length (FIGURE 2-1).
Use the #2 Phillips screwdriver to loosen the four rail adjustment screws on each rail to allow adjustment of each rail length (FIGURE 2-2).
FIGURE 2-2 Loosening the Rail Screws to Adjust the
Expansion Rail Length
Note - The expansion tray rails are preconfigured to adjust to cabinet rail depths of between 26.18 inches (664.97 mm) and 28.93 inches (734.82 mm). For cabinet rail depths outside of this range, remove and reposition the four rail adjustment screws (FIGURE 2-2) to support your required rail length. |
2. Check the contents of the box for the following items:
Select the cabinet in which you will be installing the array. Be sure the cabinet is installed as described in the installation instructions provided with it.
1. Stabilize the cabinet as described in the cabinet documentation.
2. If the cabinet has casters, make sure the casters are locked to prevent the cabinet from rolling.
3. Remove or open the top front panel.
4. Remove or open the vented back panel.
The 6540 is comprised of a controller tray and up to 14 expansion trays. The expansion trays are divided into four tray groups. A tray group is defined as the one to four trays that share the same two connections to the controller tray. They can also be identified by their tray ID's most significant digit (Tray Groups Are Defined Using Tray IDs).
Each controller in the Sun StorageTek 6540 array has four expansion ports. For optimal reliability, availability, and serviceability, you should divide expansion trays evenly among the four expansion channels, resulting in tray groupings. Tray groups enable load balancing to provide optimum system performance. TABLE 2-2 identifies the tray groupings depending on the number of expansion trays in the system.
The 6540 has two controllers with four drive channels each. For redundancy, the expansion channels are divided both logically and physically. The physical divisions are based on the ASICs on the controllers and are called Drive Channels 1 to 4. The logical divisions are based on their connections to tray groups.
To understand the physical division of the controller port drive associations, consider the following:
The required placement of the controller tray and the expansion trays in the cabinet facilitates cabling the trays in the required groups. TABLE 2-1 shows the required location of each tray in the main cabinet.
FIGURE 2-3 shows the physical location of each tray in the cabinet.
FIGURE
2-3 Physical Location of Each Tray in the
Cabinet
To understand the tray balancing among tray groups that establishes the logical divisions, TABLE 2-2 identifies the expansion trays that are included in each group. Refer to Intertray Cabling for additional information.
FIGURE 2-4 shows the allocation of tray groups within a cabinet.
FIGURE 2-4 6540 Array Tray Groups
The resulting association between the controller ports and the
drive ports and tray groups follows:
Cabling from Controller A's side is done from the bottom-up whereas the cabling from Controller B's side is done from the top-down.
Tray groups are associated with tray IDs, as follows:
FIGURE 2-5 shows the intratray cabling within a tray group.

This section describes how to cable a controller tray to expansion trays housed in a cabinet other than the Sun 1000-38 cabinet for several different configurations. The controller tray uses Controller A and Controller B drive ports to connect to the expansion ports at the back of each expansion tray.
FIGURE 2-34 Drive Ports on the Controller
Tray
The configuration naming convention is the number of controller trays x the number of expansion trays where the first number is the controller tray and the second is the number of expansion trays. For example, 1x1 is the controller tray and one expansion tray, and 1x7 is the controller tray and 7 expansion trays.
Use the following instructions to connect the dual-RAID controller tray to one or more expansion trays.
Two 2-meter FC cables are required to connect a controller tray to an expansion tray. TABLE 2-3 lists the number of FC cables required for up to four expansion trays.
TABLE 2-4 lists the cabling between one controller tray and up to four expansion trays.

The initial release of the Sun StorageTek 6540 Array was shipped in a cabinet using a patch panel. To connect to an expansion tray from one of these cabinets, you should bypass the patch panel (FIGURE 2-38):
1. Disconnect the FC cables and the Ethernet cable from the patch panel.
The initial release of the Sun StorageTek 6540 Array was shipped in a cabinet using a patch panel, which was primarily used to extend cable ports from the back of the controller and expansion trays to the rear of the cabinet. The external host FC and Ethernet cables are plugged directly into the patch panel ports, and in the case of an expansion rack, expansion tray FC cables may have also been connected to the corresponding patch panel ports.
To upgrade the system by adding additional expansion trays into one of these cabinets, you should bypass the patch panel and connect directly to the existing expansion trays as shown in FIGURE 2-52. You should bypass the patch panel for the host cables also:
1. Disconnect the host FC cables and the Ethernet cable from the patch panel and connect to the corresponding ports on the controller tray.
2. Connect the FC cables from the expansion tray upgrade directly into Expansion ports A and B on the exiting expansion tray or trays.
3. Connect the Ethernet cable directly into the Ethernet port on the expansion tray.
1. Verify that both power switches are off (see FIGURE 1-6) for each tray in the cabinet.
2. Connect each power supply in the tray to a different power source in the cabinet.
3. Connect the power cables from the cabinet to the external power source.
| Note - The power-on sequence is described in detail in Chapter 6. |
Do not power on the array until you complete the procedures in this chapter.
After installing and cabling the trays, you are ready to connect the management and data hosts, as described in Chapter 3.
