1.1 Overview Features

The Acer | HDS Workgroup Modular Storage WMS100 subsystem (hereafter referred to as the WMS100) is available in two models: the floor model and the rack-mount model.

There are two types of the WMS100 floor model. The first type is a combination of the DF700-RKXS (hereafter referred to as the RKXS) and the floor standing kit DF-F700-H1J (hereafter referred to as the Floor [RKXS+H1J] Model). The second type is a combination of the RKXS, the DF700-RKAJAT (hereafter referred to as RKAJAT), and the floor standing kit DF-F700-H2J (hereafter referred to as the Floor [RKXS+RKAJAT+H2J] Model).

The WMS100 rack-mount model is a subsystem that combines the RKXS, the RKAJAT, and the DF700-RKNAS2G (hereafter referred to as RKNAS). For information regarding model types, see sections

The following WMS100 subsystem features are discussed in this section:

 High Data Availability.  Connectivity.  Scalability.  Performance Reporting and Monitoring.

1.2 and 1.3.

 Reliability, Availability, and Serviceability.

1.1.1 High Data Availability

The Acer | HDS WMS100 is designed for high performance and protection of user data. See section

1.2 for additional information on the reliability and ava ilability features of the Acer

| HDS WMS100 subsystem.

1.1.2 Connectivity

The Acer | HDS WMS100 subsystem provides connectivity to most open systems through a standard Fibre Channel interface or Network interfaces. The following paragraphs describe the features of Fibre Channel and Ethernet:

 High-Speed Data Transfer

Fibre Channel: When using the Fibre Channel interface for host interface, the WMS100 subsystem can transfer data between the host computer and the WMS100 at a maximum speed of 200 MB/sec. Throughput can be accessed by connecting multiple devices through the Fibre Channel, even when accessing from multiple hosts to the WMS100.

Ethernet: With the 1 G bps Ethernet connection, the subsystem can transfer data between host computer and the subsystem at a maximum speed of 100 M bytes/s per port via a network. Enough throughput can be got even when having multiple access to the multiple devices connected to the same network loop.

2 Chapter 1 Overview of the WMS100 Subsystem

 Cable

Fibre Channel: With Fibre Channel, the subsystem can be located up to 300 meters from the host.

Ethernet: With Ethernet, the subsystem can be located up to 100 meters from the host. The subsystem can be installed in the location far from the host.

 The Number of Connectable Devices

Fibre Channel: The WMS100 subsystem enables you to construct a system which can connect up to 126 fibre channel devices by using the fibre channel interface and connecting the FC-AL and FC-SW.

 Security Function

Fibre Channel and Ethernet: When the system is configured to connect multiple hosts, a function is provided which rejects a boot by any host except a specified host. This function can prevent access from an illegal host.

1.1.3 Scalability

 You can construct a variety of systems; for example, a system with 15 disk drives can be

configured using a single RKXS, or a more complex system can be set up using the maximum of 105 disk drives, expanded by connecting up to 6 RKAJATs to the RKXS.

 Up to 15 spare disks can be set up in any location. Use the system effectively by

configuring each spare disk in a disk drive slot left unused due to system construction.

 From the host computer, the subsystem can be used as a single large-scale disk drive or

as 512 logical disks (LUs) maximum.

1.1.4 Performance Reporting and Monitoring

The Storage Navigator Modular program provides the capability to either monitor the disk array in real-time or to collect historical data regarding the performance of the disk array.

Acer | HDS WMS100™ User and Reference Guide 3

1.1.5 Reliability, Availability, and Serviceability

The WMS100 subsystem is not expected to fail in any way that would interrupt user access to data. The WMS100 can sustain single component failures and still continue to provide full access to all stored user data.

Note: While access to user data will not normally be compromised, the failure of any single key component may degrade performance.

The reliability, availability, and serviceability features of the WMS100 subsystem include:

 High-Availability capability. The Controller of the WMS100 subsystem increases data

reliability by adding original 8-byte data assurance codes to data from a host computer by automatically generating them, writing them in the disk drive together with the data, and checking them when reading the data. On the data bus in the controller, the automatic generation of the data assurance codes and the check are executed to enhance data reliability in data distribution/concentration control, particular to that disk array.

This function monitors potential disk failure. Before failure o ccurs, the data copy operation can be automatically performed in the background. The dynamic sparing feature enables the subsystem to replace the spare disk due to redundancy and provides high reliability.

 Redundant power supply systems. Each WMS100 unit has a set of two power supplies.

Each power supply can provide power for the entire subsystem in the unlikely event of power supply failure. The power supplies of each set can be connected across power boundaries so that each set can continue to provide power if a power outage occurs. Each unit of the WMS100 can sustain the loss of a single power su pply and still continue operation.

 High capacity cache. The WMS100 subsystem supports 1 GB high capacity cache per

controller. Writing completion can be reported to the host system when data is written to cache.

 Spare disk. To maintain the reliability, it is recommended that one spare disk is set for

15 disk drives in the subsystem with S-ATA disk drives.

4 Chapter 1 Overview of the WMS100 Subsystem

1.2 Rack-Mount Model

The rack-mount model is composed of a single RKXS or a combination of the RKXS, RKAJAT, and RKNAS mounted on a rack frame. The RKXS is capable of mounting up to 15 disk drives; a controller to perform RAID control on the drives is included. The RKAJAT is capable of mounting up to 15 disk drives and controls the drives through a connection with an RKXS. The RKAJAT is provided with no controller.

2.2.3.5 Nickel-Hydride Rechargeable Battery Instructions

These instructions explain what you must observe when you use a nickel-hydride rechargeable battery (hereafter it is referred to as the battery). If you use the battery incorrectly, it can overheat ignite, burst, or explode, damaging and deteriora ting its performance/life. Read and follow the instructions below:

Danger

1. Do not disassemble the case; do not modify it or peel off the label. There are high voltage parts inside: if you attempt any of these actions, this can result in electrical shock or burning.

2. Do not disassemble the battery; this can cause short circuits inside or outside of the battery. If the components are exposed to the air, the battery can overheat, burst or ignite. Disassembling the battery can expose you to alkaline solution, which can be dangerous.

3. Do not cut the output cable. Do not modify the connector. If you attempt any of these actions, an electrical shock or burn can result. A short-circuit may cause abnormal chemical reactions inside the battery which leads to overheating, bursting or ig nition.

4. Follow the instructions when you recharge the battery pack. If you recharge it in a way different from specified here, it may cause the following problems: The battery may become charged excessively; excessive current may be produced; or the battery cannot be recharged. As a result, the battery may leak, become overheated, burst, or ignite.

5. Do not use excessive force when you connect the battery pack to the charger or other devices. If you cannot connect it easily, check that the positive and negative positions are correct for the connector. If you connect the battery in reverse, it will be charged incorrectly and abnormal chemical reactions may occur inside. As a result, the battery may become overheated, burst or ignite.

6. Do not connect the battery to a power receptacle. If you apply an excessive amount of voltage to the battery, it may produce excessive current making the battery overheat, burst or ignite.

7. Do not use or leave the battery where the temperature can become high, such as, near a fire or a heating element. High temperatures can damage the battery's separator, which may cause short circuit, making it overheat, burst or ignite.

8. Do not incinerate or heat the battery pack. If you do so, the insulator may melt, the safety fuse/mechanism may be damaged, or the electrolyte may gush out. As a result, the battery can burst, explode or ignite.

9. Do not connect the negative terminal to the positive with metal wire. Do not carry or store the battery with other metal parts. This can cause a short circuit or produce an excessive current which can cause the battery to leak, overheat, burst or ignite.

10. Do not let the battery become wet by soaking it in the water or seawater. If the battery becomes wet, a short circuit can occur and an excessive amount of current can be produced, causing abnormal chemical reactions inside. As a result, the battery may become overheated, burst or ignite.

Acer | HDS WMS100™ User and Reference Guide 13

11. Do not nail or hammer the battery. The battery may be broken or dented and a short circuit may occur inside. As a result, the battery may become overheated, burst or ignite.

12. Do not solder directly to the battery. If you do so, heat will melt the insulator and damage the safety fuse/mechanism. As a result, the battery may leak or may become overheated, burst or ignite.

Warning

13. If you find anything strange or unusual with the battery when you use/carry/store it, remove the battery from the device and stop using it. For example, strange smells, strange colors, or deformation are a sign you must stop using the battery.

14. If it takes longer than the specified time to complete recharging, stop recharging the battery; otherwise, the battery may become overheated, burst or ignite.

If the battery leaks and gets into your eyes, immediately flush your eyes with clean water (tap water) and do not rub your eye. Visit the doctor immediately. If you do not seek any treatment for your eyes, problems may occur later. Because the battery uses highly concentrated alkaline as electrolyte, it can burn; you may lose your sight if it makes contact with your eyes. If the battery's liquid contacts your skin or eyes, you must flush them with plenty of clean water and visit a doctor at once.

2.2.3.6 Miscellaneous and Other

3.1 WMS100 Rack-Mount Model

The following steps describe power on/off procedures for the WMS100 rack-mount model.

Note: For information about the global rack-mount model, refer to the Acer | HDS Global 19-Inch Rack Reference Guide.

3.1.1 Subsystem Power On

Note: The EALM lamp (red) of the controller (on the rear side of the subsystem) may come on between subsystem power-on and Ready status. However, it is not a problem if the EALM lamp (red) goes out during this period of time.

To power on the subsystem:

1. Verify that the main switch is turned off.

2. Verify that the AC power unit switch of each power unit is turned off.

3. Verify that the circuit breaker is turned off.

4. When the RKNAS is mounted on the rack, verify that the AC Power Unit Switch of the power unit on the RKNAS is turned off.

5. Turn on the circuit breaker of the PDB.

6. Turn on the AC Power Unit Switch of the power unit on RKNAS.

7. Turn on the AC power unit switch of the power unit on the RKAJAT.

Note: When two or more disk drives are not installed on the additional disk drive unit side, shut off the power to the RKAJAT power unit.

8. Turn on the AC power unit switch of the power unit on the RKXS.

9. Turn on the main switch.

10. Verify that the READY LED (green) on the RKXS lights within five minutes. When the RKNAS is connected to the WMS 100, verify that the READY LED (green) on the RKNAS lights another three minutes later. If the READY LED (green) on the RKS blinks at a high pace, it blinks for up to 15 minutes because the download of the SENC firmware is executed. Even when the READY LED (green) blinks, the subsystem is operational. If the ALARM LED (red) or WARNING LED (orange) lights, refer to section

8.1.

Note: The EALM lamp (red) of the control unit (on the rear side of the subsystem) may come on between the powering on of the subsystem and entry into the Ready status of the RKXS. However, it is not a problem if the EALM lamp (red) goes out until the subsystem enters the Ready status.

36 Chapter 3 Powering On/Off Procedure

Note: A NAS system may not be accessed from a host computer even though the READY LED of NAS unit illuminates. A NAS system accepts access from a host computer only in the "ACTIVE" NAS OS Condition.

4.2 Redundant Power Supplies

Each WMS100 unit is powered by its own set of redundant power supplies, and each power supply is able to provide power for the entire RKXS unit, should it become necessary. Because of this redundancy, the WMS100 subsystem can sustain the loss of a power supply and still continue operation. To make use of this capability, the two power supplies of each WMS100 unit should be connected either to dual power sources or to different power panels, so if there is a power failure on one of the sources, the WMS100 subsystem can continue full operations using power from the alternate source.

RKNAS has no redundancy of power supplies.

Acer | HDS WMS100™ User and Reference Guide 53

4.3 Fibre Channel Interface

The WMS100 subsystem supports open system operations. The WMS100 sub system supports up to 2 fibre-channel ports. Each WMS100 Fibre Channel interface is capable of operating at data transfer speeds of up to 200 MB/sec. The WMS100 extends up to 4 Fibre Channel ports by adding optional FC interface board.

The WMS100 supports shortwave multimode optical cables. With these shortwave fibre channel cables, the WMS100 subsystem can be located up to 300 meters from the opensystem host.

Note: For the interface, refer to Appendix D.

4.3.1 Mini-HUB

When the FC interface board is not added to the control unit, the host interface of WMS100 has Mini-HUB in the control unit, and enhances one port to two host connectors. However, the link status between the host and the WMS100 is recognized as one port.
