  • Page 24: Overview Features

    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).

  • Page 25: Scalability

    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.

  • Page 26: Reliability, Availability, And Serviceability

    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.
