Features of the Disk Module

The Sun Blade 6000 Disk Module is a blade for the Sun Blade 6000 Modular System that contains disks. It communicates with server blades through Network Express Modules that support SAS, specifically the Sun Blade 6000 Multi-Fabric NEM and the Sun Blade 6000 10GbE Multi-Fabric NEM.

TABLE 1-1 summarizes the features of the disk module.

TABLE 1-1    Features of the Sun Blade 6000 Disk Module 

Feature	Specifications
Disk Drives	Eight total with front panel access. The storage blade supports SAS or Solid State (SSD) disk drives.
Types	SAS (2.5 inch or 63.5 mm).
Disk Drive Bracket	Sun disk drive mounting bracket.
Management	2 Arm7-S Processors (SAS expander devices). 2MB SRAM code storage, 2MB FLASH, 8K Serial EEPROM.
Data Rates	1.5 and 3.0 Gbit/sec. SAS with auto-negotiation. Two 1x or one 2x wide connections into blade. 12 Gbit/sec total.
Protocols	SAS - Serial Attached SCSI - v1.0, v1.1. SSP - Serial SCSI Protocol. SMP - Serial Management Protocol. SES - SCSI Enclosure Services.
Indicators	SIS indicators: Activity and Fault for drives and blade. Locate for blade only.
Health	Voltage monitoring, temperature monitoring, disk fault detection, and blade fault detection.

TABLE 1-1 summarizes the physical specifications of the disk module.

Sun Blade 6000 Disk Module Orientation

This section contains illustrations that you can use to become familiar with the Sun Blade 6000 disk module.

FIGURE 1-2 shows the features of the front panel.

TABLE 1-3   Front Panel LED Functions

	LED Name	Description
1	Combined Locate button and LED (white)	This LED helps you to identify which system in the rack you are working on in a rack full of servers. Push and release this button to make the Locate LED blink for 30 minutes. When Locate LED is blinking, push and release this button to make the Locate LED stop blinking. Hold down the button for 5 seconds to initiate a “push-to-test” mode that illuminates all other LEDs for 15 seconds. This LED can also be made to blink from a remote system using the CMM ILOM. Refer to the Sun Blade 6000 Disk Module Administration Guide for details.
2	Ready-to-Remove LED (blue)	Not used.
3	Module Fault LED (amber)	This LED has two states: On: An event has been acknowledged, and service action is required. Off: Normal operation.
4	Module Activity LED (green)	This LED has three states: Off: Module is offline. On: Module is online. Slow blinking (1 Hz at 50% duty cycle): Module is booting or configuring (firmware flash update in progress).
5	Disk Drive OK LED (green)	This LED has three states: On: Power is on and disk is online. Off: Disk is offline. Blinking: Irregular blinking means normal disk activity; steady, slow blink means a RAID volume is rebuilding on this disk.
6	Disk Drive Fault and Locate LED (amber)	This LED has four states: On: Disk fault. Service action required. Off: Normal operation. Slow blink: Disk failure predicted. Fast blink: Locate function activated.
7	Ready-to-Remove LED (blue)	Not used.

The events that can cause a disk blade’s Module Fault LED (amber) to turn on are:

• Temperature out of range.

• Voltage out of range.

  Note - A severe over-temperature condition will shut down the disk blade.

CRUs and FRUs

For the Sun Blade 6000 Disk Module, the Customer Replaceable Units (CRUs) are the disks in the disk module. There is only one Field Replaceable Unit (FRU), which is the disk module itself.

If either a disk or a disk module fails, you must replace it, because there are no replaceable subassemblies.

You can replace the disks and the disk blade yourself.
