Server Power Supplies
A system's power supply provides power to all of its components. The power supply systems for all units are auto-sensing devices, with automatic adoption to line voltages from 100 to 240 volts, 50 to 60 Hz.
The power supply system in the server comprises two redundant hot-swappable modules in a 1 + 1 configuration, as shown in FIGURE D-5. Each module is capable of maintaining a load of 500 watts. One power supply is required for system operation, with the second power supply providing power redundancy.
FIGURE D-5 Power Supply Modules
Each power supply has the following capabilities:
- 550 watt output
- Internal multi-speed cooling fans
- Built-in load sharing
- Built-in overload protection
- Integral handle for ease when inserting/extracting the device
In a cluster configuration, if one of the servers experiences a power failure, both servers are rebooted under OS control. In this configuration, both servers detect the failure and reset themselves to correct the failure.
Direct-Attached Tape Library
You can attach a local tape backup device through the SCSI port on the back of the server (PCI slot 2). Set the SCSI ID of the tape library to be lower than the tape drive ID. For example, you might set the library ID to 0 and the drive ID to 5.
Make sure the tape device you attach is supported by the NAS appliance or gateway system. For the most current information on supported tape devices, contact your Sun sales representative.

Sun StorageTek 5320 Controller Units and Expansion Units
|
This section describes the hardware components for Sun StorageTek 5320 controller units and expansion units, as follows:
- Controller Units provides an overview of the 5320 controller units, including RAID capacity.
- Expansion Units provides an overview of the 5320 expansion units, including RAID capacity, indicators and LEDs, and the battery backup compartment.
- Mixed FC and SATA Capacity provides guidelines to follow when combining Fibre Channel (FC) and Serial Advanced Technology Attachment (SATA) drives.
- Disk Drives provides an overview of the 5320 drive shuttles, including information about failures and how to locate a particular physical drive.
Controller Units
Sun StorageTek 5320 controller units provide back-end storage for appliance (non-gateway) configurations. For increased capacity, they can be used with Sun StorageTek 5320 Expansion Units (see "Invalid Cross-Reference Format").
Each controller unit and expansion unit contains either 8 or 16 redundant array of independent disks (RAID) drives of a single drive type (either Fibre Channel (FC), or Serial Advanced Technology Attachment (SATA).
- The FC controller unit contains either 8 or 16 hot-swappable hard drives organized as one or two redundant array of independent disks (RAID)-5 sets, respectively, plus one global hot-spare. The RAID sets are pre-configured: the first 8 drives as one hot spare plus one 6+1 RAID set; the remaining half, if used, as a 7+1 RAID set.
For FC drives, the 6+1 RAID set forms a single volume, and the 7+1 RAID set, if present, forms two volumes of equal size.
- The SATA controller unit also contains either 8 or 16 hot-swappable hard drives, organized into RAID sets as described above for the FC drives. Each SATA RAID set forms two volumes of equal size.
The table below summarizes the possible configurations for each type of supported drive. Check the release notes for any additional supported drives.

Mixed FC and SATA Capacity
Mixed Serial Advanced Technology Attachment (SATA) and Fibre Channel (FC) configurations are supported with the following restrictions:
- Each controller and expansion unit must contain all FC drives or all SATA drives. Do not mix FC and SATA drives within a controller unit or expansion unit.
- The controller unit can contain FC drives even if one or more expansion units contain SATA drives.
- The controller unit can contain SATA drives even if one or more expansion units contain FC drives.
- Each array (controller unit and connected expansion units) can contain mixed FC and SATA drives. However, because SATA drives are so much slower than FC drives, connect any SATA expansion units at the end.
- In a dual-array configuration, the arrays can be configured differently (different types of drives).
- A unique hot-spare must be available for both SATA and FC in the same capacity as used in the array.
- Logical unit numbers (LUNs) cannot include both SATA and FC drives.
- Expansion units must be at the same firmware level as the RAID controller to which they are connected. For example, if you add an expansion unit at firmware level 1.2 to a RAID controller unit at firmware level 1.0, you must upgrade the entire system to level 1.2.
Disk Drives
Only FC or SATA drives supplied by Sun Microsystems work with the NAS appliances. For the most current support information, contact your Sun sales representative.
Each drive is encased in its own drive shuttle, as illustrated below:
FIGURE D-9 Sun StorageTek 5320 Fibre Channel Drive Shuttles
When a drive is determined to be bad, contact Sun Services to replace the failed drive.
Drive shuttles can be replaced individually, without shutting down the expansion unit, controller unit, or NAS server. As necessary, only hot-swap one drive shuttle at a time. Confirm that the RAID subsystem has completed any necessary rebuild before removing another drive shuttle.
Identifying a Drive for Replacement
If a disk drive fails, use the system log or a diagnostic report to identify the drive. The example below shows an entry from the system log:
Controller 1 enclosure 0 row 0 column 6
|
This example references the drive in slot 7 of the first enclosure in the first array. Use the guidelines below to interpret log entries and diagnostic reports. Ignore any channel and target numbers that display in the log (not illustrated above). These are maintained for compatibility with legacy systems.
- Controller numbering starts at 0. The controllers in the first array (that is, the first controller unit) are 0 (slot A) and 1 (slot B), and the controllers in the second array are 2 and 3. The arrays are numbered by the NAS OS when you first start up the system after installation, in order as you boot them. If you follow the recommended power-up sequence, the first HBA port on the server (PCI 1) is connected to the first array (controllers 0 and 1), and the second HBA port (PCI 0) is connected to the second array.
- Enclosure numbering starts at 0 and is relative to the array to which it belongs. For example, if the first array has a controller unit and one expansion unit, they are identified as enclosures 0 and 1. Additional expansion units are numbered in the order in which they were booted when you first started up the system after after installing the NAS device. The Getting Started Guide details the recommended power-up sequence.
- The row number is always 0.
- Column numbering starts at 0, and identifies the physical position of the drive as you face the controller unit or expansion unit from the front, moving left (column 0) to right (column 15).
Note: The numbering on the physical device (silk screen) runs from 1 to 16, corresponding to columns 0 through 13.
Locating a Drive
To locate a particular drive, see Locating a Drive or Controller/Expansion Unit. This will cause the drive indicator lights to flash for a selected drive.
Sun StorageTek 5220 NAS Appliance
|
The Sun StorageTek 5220 NAS Appliance is the basic unit. FIGURE D-1 shows the front of the appliance. You need the software serial number for any calls for service and for adding licenses and you need the hardware serial number if you decide to expand the system.
FIGURE D-22 Sun StorageTek 5220 NAS Appliance, Front
FIGURE D-3 shows the back of the appliance. The appliance contains a dual-port fibre channel (F C) host bus adapter (HBA) card in PCI slot 1. The other slot, PCI slot 0, can be empty or contain one of the optional cards.
FIGURE 4-23 Sun StorageTek 5220 NAS Appliance With Single HBA Card, Back
One of the ports on the HBA card in PCI slot 1, HBA Port 2, can be used for connecting to tape backup. Its other port, HBA Port 1, is dedicated to connecting to the controller unit.
PCI slot 0 can contain the following options:
- A dual-port copper 10/100/1000 Gigabit Ethernet card
- A dual-port optical Gigabit Ethernet card
- A FC HBA card for tape backup
- A SCSI HBA card for tape backup
An uninterrupted power supply device (UPS), using the USB-to-Serial Port Adapter/Convert Cable included in the ship kit. If a power outage occurs, the UPS maintains the operation of the system. If the battery in the UPS loses power, the UPS performs a graceful shutdown of the system. Connecting the UPS adapter cable to a supported local UPS device enables the appliance to monitor the state of the UPS.
Back-End Storage
The RAID controller unit provides direct-attached back-end storage for the Sun StorageTek 5220 NAS Appliance. At a minimum, the system has an appliance and one controller unit containing SATA disk drives. In addition to the appliance and controller unit, you can set up additional back-end storage by connecting one or two expansion units to the controller unit, as described in Expansion Units.. Each expansion unit must contain only SATA disk drives.
