Overview of the Hitachi NAS Platform. The 3080 and 3090 G2 hardware reference explains how to configure the hardware and software, and how to replace faulty components.
- Child Topics
- System components
The system contains many components and is housed in a rack or cabinet. This section describes the main system components.
- Server specifications
The following specifications are for the server. Except for the power and cooling values, these specifications do not reflect differences among models; they are the maximum for all server models. For more detailed specifications of a particular model or configuration, contact your representative.
- Attaching a rack stabilizer plate
A rack stabilizer plate and mounting hardware are supplied with some system configurations. Hitachi Vantara recommends that you always use the stabilizer plate when provided. Use of a stabilizer plate is required for those installations with dense trays.
- Ventilation
- Server front panel
The front of the server features a removable bezel that shields the front-facing server components.
- LED status indicators
The LEDs (light emitting diodes) on the front of the chassis indicate the overall status of the server, as well as the status of some of the individual components. The NVRAM backup battery pack, each of the hard disk drives, and each of the fan assemblies has a status LED.
- NVRAM backup battery pack
Each server contains a battery pack. The battery pack maintains the NVRAM contents when the server is not receiving power (due to a power failure or a short-term shut down). The battery pack is located behind the front bezel cover of the server, on the left-hand side. The battery pack is hot-swappable and can only be accessed after the front bezel has been removed.
- Hard disk drives
The server contains two hard disks, which are configured as a Linux SW RAID 1 pair, and they store server or cluster-related data. These hard disks are not part of the customer-usable data storage that is available to the server.
- Fans
The server features dual hot-swappable fan assemblies. The fans provide for front-to-back airflow to be consistent with other storage system components.
- Server rear panel
The rear panel of the server features numerous ports, connectors, switches, and LEDs.
- Rear panel server LED and button locations
The rear panel of the server contains three (3) status LEDs that indicate server status and two (2) buttons that are used to power up and reset the server.
- Management interfaces
The server panel features two types of physical management ports: RS-232 Serial (DB-9) and 10/100/1000 Ethernet (RJ45).
- Ethernet cables
- Field-replaceable units
Some components are field-replaceable units (FRUs).
- Hot-swappable components
Some components are hot-swappable. Such components can be changed without shutting down the server.
- Removing and replacing the front bezel
To access some server components, or field replaceable units (FRUs), you must first remove the front bezel. Replace the bezel after the part replacement is complete.
- Replacing a fan
Replace a fan assembly, which is one of the server's hot-swappable components.
- Recovering or replacing a hard disk
Some hard disk drive failures require disk replacement, others only require performing a recovery process. Use the recovery process to help ensure that all partitions are recovered before proceeding with any further disk recovery or replacement procedures. Unless you are certain the hard disk has failed, perform a disk recovery.
- Replacing the NVRAM backup battery pack
To replace the NVRAM backup battery pack in a server, you remove the old battery and install the new replacement. Perform the battery pack replacement as quickly as possible, and only when the new pack is present.
- Replacing a power supply unit
You can replace a power supply unit (PSU) as a hot-swappable server component. The server can operate on a single PSU if necessary, making it possible to replace a failed PSU without shutting down the server. If a PSU fails, it should be replaced as quickly as possible, because operating on a single PSU means that there is no redundancy in that area, increasing the risk of an interruption in service to clients.
- Replacing an FPGA board as a FRU
Typically, when an FPGA board fails, the whole Hitachi NAS Platform server is replaced. However, in some cases with the HNAS 3080 and 3090 platform models, an FPGA board may be replaced as a field replaceable unit (FRU).
- Rebooting or shutting down a server
- Rebooting or shutting down a cluster
- Restarting an unresponsive server
- Powering down the server for maintenance
- Powering down the server for shipment or storage
Follow this procedure whenever a server is to be powered down and will be left off for more than a day. If the system is being restarted or power-cycled, this procedure is not required.
