## Background
CROSS REFERENCE TO RELATED APPLICATIONS
This is a continuation of U.S. application Ser. No. 13/002,603, filed Jan. 4, 2011, which is a national stage application under 35 U.S.C. §371 of PCT/US2008/069021, filed Jul. 2, 2008, which are both hereby incorporated by reference in their entirety.


BACKGROUND
A network-attached storage (NAS) system is a system that can be attached to a network and that is specifically designed for data storage. Software residing on the NAS system usually provides functionality that is specific to data storage. Typically, the software on the NAS system does not include higher-level software such as database system management software, or other application software not specific to data storage.
Since a NAS system is typically dedicated to providing data storage, data storage performance can be enhanced since the NAS system does not have to be responsible for performing other types of processing. A NAS system is connected to a network to allow for host systems to access the NAS system. Moreover, a NAS system provides file-level data storage, rather than block-based data storage.
An enterprise (e.g., company, educational facility, government entity) can often have a large number of client devices (e.g., computers) that have to be configured to access NAS systems. Traditionally, a client install compact disk (CD) is provided to each client device to load NAS-related software onto the client device. Also, to properly install the NAS-related software, a network administrator typically has to perform the software installation. In a large enterprise that can have users located at many different geographic locations, installing NAS-related software at the client devices and setting up the client devices for NAS access can be time consuming and inefficient. Moreover, when installing NAS-related software, typically all software components on the client install CD are loaded onto the client device. Some of the software components loaded may never be used by a particular user, and therefore, installing such software components would be wasteful of resources at the client device.

DETAILED DESCRIPTION
In accordance with some embodiments, a technique or mechanism is provided to enable efficient performance, at a client device, of administrative tasks associated with a network-attached storage (NAS) system. A NAS system refers to a file-level based storage system that has software (including an operating system and other software) that provides functionality related to data storage and data access, as well as functionality related to management of such data storage/access. The NAS system is connected to a network, such as a local area network (LAN), wide area network (WAN), or other type of network to enable client devices to access the NAS system. The operating system provided on a NAS system is typically a reduced functionality operating system (such as an embedded operating system) that enables file transfer (storage of files or access of files). Various operating systems have been specifically designed for use on NAS systems; each such operating system is referred to as a NAS OS.
To enhance performance of selected administrative tasks associated with a NAS system at a client device, the NAS system is provided with installer code that can be downloaded by a client device through a web browser. The NAS system has a web interface that allows for convenient access by a web browser of the client device. The installer code, once downloaded and executed at the client device, then is able to present a user interface, such as a graphical user interface (GUI), with various menu items and fields to allow a user to select administrative tasks associated with the NAS system to perform. In one example, a series of questions can be provided in the GUI that the user can answer. Based on the answers provided by the user and/or based on other selections made by the user at the client device, the installer code at the client device will then perform selected administrative tasks.
The selected administrative tasks include setting up a user account at the NAS system, downloading selected software components (such as less than all of the software components associated with the NAS system) at the client, setting up shared folders at the NAS system, synchronizing user information between the client device and the NAS system, and so forth.
FIG. 1A illustrates an exemplary arrangement that includes a NAS system 100 connected to a network 102 (e.g., LAN, WAN, etc.). Also connected to the network 102 are client devices 104, where the client devices 104 can be computers (desktop or notebook computers), personal digital assistants (PDAs), network appliances, and so forth. Although depicted as a single network, it is noted that network 102 can actually include multiple networks in some implementations. In fact, the network 102 can represent a collection of networks, with client devices connected to such collection of networks possibly located geographically far apart from each other. For example, FIG. 1B shows client devices 104A and 104B connected over a wired home network 158 and through a router 152 to a server 150, which can contain the NAS system 100 of FIG. 1A. A client device 104C is connected by a wireless link 154 to the router 152. Also, client devices 104D are connected over the Internet 156 and through the router 152 to the server 150.
The NAS system 100 of FIG. 1A includes a NAS device 106 (sometimes referred to as a NAS head) that is accessed by a client device 104 for storing or retrieving data contained in one or more storage devices 108 connected to the NAS device 106. The storage devices 108 can be disk-based storage devices or other types of storage devices.
The NAS device 106 contains a central processing unit (CPU) 110 and memory 112. In accordance with some embodiments, the memory 112 stores installer code 114 that can be downloaded to a client device 104 through a web interface 116 in the NAS device 106. For example, a user at the client device can simply type in a uniform resource locator (URL) at the client device to allow a web page containing a link to the installer code 114 to be presented at the client device 104. The memory 112 can be the local temporary or volatile memory of the NAS device 106. Alternatively, instead of the installer code 114 being stored in the memory 112, the installer code 114 can be stored in one of the storage devices 108.
The NAS device 106 also includes a NAS OS 118, which as explained above, is a reduced functionality operating system with less features than a full-feature operating system such as a network operating system (NOS). Also, the NAS device 106 includes a file-based protocol module 120 to provide file-level access of data contained in the storage devices 108. File-level access of data refers to the storage or retrieval of data one file at a time; this is contrasted with block-level access of data in which data is stored or retrieved a block at a time, where a block can be smaller than or larger than a file. Examples of the file-based protocol module 120 include an NFS (network file system) module, CIFS (common Internet file system) module, SMB (server message block) module, or others.
As further depicted in FIG. 1A, a client device 104 includes a web browser 122 that is executable on a CPU 124 of the client device 104. The CPU 124 is connected to a memory 126 of the client device 104, where the memory 126 can be used to store installer code 114A downloaded from the NAS device 106. The other client devices 104 can include similar components.
By using the web browser 122, a convenient mechanism is provided to a user to request the installer code 114 of the NAS system 100 to allow such installer code 114 to be downloaded from the NAS system 100 to the client device 104. The installer code 114 can be an ActiveX component, where ActiveX is a technology developed by Microsoft Corporation. ActiveX controls (which are software modules) can be downloaded from a server computer and executed on a client computer outside of a web browser. Alternatively, instead of being an ActiveX component, the installer code 114 can be a Java applet, or some other type of code that can be downloaded from a server to client for execution on the client.
FIG. 2 shows execution of the installer code 114A on the CPU 124 of the client device 104. When executed, the installer code 114A presents a GUI screen 202 in a display device 200 of the client device 104. The GUI screen 202 can actually be presented in the web browser 122 user interface (not shown in FIG. 2). The GUI screen 202 can include control icons and/or menus 204, and fields 206 containing questions that can be answered by a user. The control icons and/or menus 204 allow a user to select one or more administrative tasks to perform with respect to the NAS system 100. The fields containing questions 206 presented in the GUI screen 202 can be in response to activation of one or more of the control icons and/or menus 204. Selections made at the control icons and/or menus 204, as well as answers responsive to the fields containing questions 206, can be stored as user selections/answers 208 in the memory 112 of the client device 104.
Also, other user information 210 can be stored in the memory 112, where such other user information can include user account information (e.g., account name and password) that was entered by the user when logging into the client device 104. Other types of user information 210 can include, as examples, user profile information, user preferences, and so forth.
In accordance with some embodiments, synchronization of the user information 210 can be performed between the client device 104 and the NAS system 100. For example, synchronizing the user information 210 allows an account to be set up at the NAS system 100 such that private information associated with the particular user can be protected at the NAS system 100. Private user information protected by user account information can be accessed only by a client device at which the corresponding user has logged in. By synchronizing such user information 210, the user would not have to re-enter account information to set up the user account at the NAS system 100, which enhances convenience to the user.
Also, based on the user selections/answers 208 at the client device 104, the installer code 114A can perform selected administrative tasks relating to the user selections/answers 208. Note that the selected administrative tasks performed can include a subset (less than all) of all possible administrative tasks associated with the NAS system 100.
Examples of the administrative tasks include setting up a user account at the NAS system, installing a subset of software components on the client (such as installing a backup software component to perform backup from the client device 104 to the NAS system 100, a control software component to manage the NAS system 100, and other software components); setting up shared folders at the NAS system 100 to allow multiple users to access data contained in the shared folders; changing or setting up a security setting for the client device 104 at the NAS system; setting up one or more firewall ports at the NAS system 100; and so forth. Changing the security setting can involve reducing the security setting of one or more files such that more users can access such file(s) at the NAS system 100, or increasing the security setting of one or more files. Setting up a firewall port refers to establishing firewall protection for a particular port of the NAS system 100 to prevent unauthorized access of that port.
FIG. 3 is a flow diagram that depicts various tasks performed at a client device 104 according to an embodiment. The client device 104 can request (at 302), with the web browser 122 (FIG. 1A), the installer code 114 contained in the NAS system 100. For example, the user can enter the URL of the website associated with the web interface 116 (FIG. 1A) of the NAS system 100, and a web page containing a link to the installer code 114 can be displayed. The user at the client device can click on the displayed link to cause download of the installer code 114 to the client device 104.
In response to the user request, the installer code 114 is downloaded (at 304) to the client device 104. The installer code is then executed (at 306) at the client device 104. The executed installer code presents an administrative user interface (such as the GUI screen 202 of FIG. 2). Selections made by the user in the administrative user interface, as well as answers provided to questions posed by the administrative user interface, are received (at 310) in the client device 104. Based on the received selections/answers, the installer code is able to perform selected administrative tasks associated with the NAS system 100.
In an alternative embodiment, it is possible that when the user makes the request to the NAS system 100 for the installer code 114, information about the user as well as information regarding the client device 104 is provided to the NAS system 100. Based on such information, the NAS system 100 can generate a recommendation, which can be downloaded with the installer code and displayed to the user in the administrative user interface, of what tasks should be performed by the user. This recommendation from the NAS system 100 can be used as a guide on selections to be made in response to answers provided by the installer code.
If later the user desires to change the selections that were previously made, the user can activate a “change” control element (which can be one of the control icons or menus 204 presented in the GUI screen 202 of FIG. 2) to cause management software to be executed. The management software can display the selections previously made by the user, and can provide fields to enable the user to make changes to any of such selections.
In some embodiments, updates of the installer code are also possible. In one example, whenever the NAS system 100 determines that an installer code similarly sent to a client device has changed, the NAS system 100 can send a notification that updated installer code is available. For example, the NAS system 100 can send an e-mail to the user. The user can then request download of the updated version of the installer code. Alternatively, an automated update feature can be provided, where the client device is able to automatically detect or be notified of updates to the installer code (similar to update notifications provided with operating systems such as WINDOWS® operating systems from Microsoft.
Instructions of software described above (including the installer code 114/114A, web browser 122, NAS OS 118, file-based protocol module 120, etc. of FIG. 1A) are loaded for execution on a processor (such as one or more CPUs 110 or 124 in FIG. 1A). The processor includes microprocessors, microcontrollers, processor modules or subsystems (including one or more microprocessors or microcontrollers), or other control or computing devices. A “processor” can refer to a single component or to plural components.
Data and instructions (of the software) are stored in respective storage devices, which are implemented as one or more computer-readable or computer-usable storage media. The storage media include different forms of memory including semiconductor memory devices such as dynamic or static random access memories (DRAMs or SRAMs), erasable and programmable read-only memories (EPROMs), electrically erasable and programmable read-only memories (EEPROMs) and flash memories; magnetic disks such as fixed, floppy and removable disks; other magnetic media including tape; and optical media such as compact disks (CDs) or digital video disks (DVDs). Note that the instructions of the software discussed above can be provided on one computer-readable or computer-usable storage medium, or alternatively, can be provided on multiple computer-readable or computer-usable storage media distributed in a large system having possibly plural nodes. Such computer-readable or computer-usable storage medium or media is (are) considered to be part of an article (or article of manufacture). An article or article of manufacture can refer to any manufactured single component or multiple components.
