EMI Regulation
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate rad io frequency energy and, if not installed and used in accordance with the instruction manual, may cau se harmful interference in which case the user will be required to correct the interference at his own expense. Testing was done with shielded cables. Therefore, in order to comply with the FCC regulations, you must use shielded cables with you installation.
Acer | HDS WMS100™ User and Reference Guide ix
If trouble occurs in a different configuration, the user may be requested to take appropriate preventive measures. The EMI test was done in the following configuration:
WMS100-RKXS+H1J WMS100-RKXS+RKAJAT+H2J
Convention for Storage Capacity Values

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.

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.
Acer | HDS WMS100™ User and Reference Guide 5

1.3 Floor Model

There are two floor model styles:
Floor (RKXS+H1J) Model. Floor (RKXS+RKAJAT+H2J) Model.
The Floor (RKXS+H1J) Model is capable of mounting up to 15 disk drives and include a controller to perform RAID control on the drives. The Floor (RKXS+RKAJAT+H2J) model is capable of mounting up to 30 disk drives and includes a controller to perform RAID control on the drives.
Note: For the specifications of the Floor model, refer to
Chapter 2.

Chapter 2 Planning for Installation and Operation

This chapter provides information for planning and preparing a site before and during installation of the Acer | HDS WMS100 subsystem. Please read this chapter carefully before beginning your installation planning.
Note: The general information in this chapter is provided to assist in installation planning and is not intended to be complete. The internal WMS100 installation and maintenance documents used by Acer | HDS personnel contain complete specifications. The exact electrical power interfaces and requirements for each site must be determined and verified to meet the applicable local regulations. For further information on site preparation for WMS100 installations, contact your Acer | HDS account team or the Acer | HDS Support Center.
