2 Chapter 1 Overview of the WMS100 Subsystem
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
1.2 and 1.3.
The following WMS100 subsystem features are discussed in this section:
High Data Availability.
Connectivity.
Scalability.
Performance Reporting and Monitoring.
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 availability 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.
