Methods and devices for booting a network attached storage with two logical units

摘要

A data storage device may comprise data storage comprising a first logical unit configured to store user data and a second logical unit configured to store an operating system. A first interface may be configured to couple to a host and a second interface may be configured to couple to a network. In a first mode, the data storage device may be configured to expose the first logical unit to the host and render the second logical unit inaccessible and, in a second mode, the data storage device may be configured to allow access to both the first and the second logical units. The first mode may comprise a direct attached storage (DAS) mode and the second mode may comprise a network attached storage (NAS) mode.

1. A data storage device, comprising:
data storage comprising a first logical unit configured to store user data and a second logical unit configured to store an operating system; a first interface configured to couple to a host; and a second interface configured to couple to a network, a second controller coupled to the second interface; and a first controller selectively configured to be coupled to one of the first interface and the second controller; wherein, in a first mode, the data. storage device is configured to render the first logical unit accessible to the host and render the second logical unit inaccessible to the host and, in a second mode, o render both the first logical unit and the second logical unit accessible to the host, and wherein the second controller is only active when the data storage device operates in the second mode.
