2. Comparing Administrative Hidden and Standard Shares CIFS supports both administrative shares and standard shares Administrative shares are shares with a last character of Administrative shares are not included in the list of shares when a client browses for available shares on a CIFS server Standard shares are shares that do not end in a character Standard shares are listed whenever a CIFS client browses for available shares on a CIFS server The NAS 2000s supports both administrative and standard CIFS shares To create an administrative share end the share name with the character when setting up the share Do not type a character at the end of the share name when creating a standard share Planning for Compatibility between File Sharing Protocols When planning for cross platform share management on the NAS 2000s it is important to understand the different protocols and their associated constraints Each additional protocol that is supported adds another level of constraints and complexity NAS 2000s Administration Guide 125 Folder Printer and Share Management NFS Compatibility Issues When planning to manage CIFS and NFS shares consider two specific requirements Note Further information including details about the NFS Service and the User Mapping service is available in the UNIX File System Management chapter m NFS service does not support spaces in the names for NFS file shares NFS translates

18. 46 Figure 21 Configuring the physical drives into an array dramatically improves read write efficiency Because the read write heads are active simultaneously the same amount of data is written to each drive during any given time interval Each unit of data is termed a block The blocks form a set of data stripes over all the hard drives in an array as shown in Figure 22 Figure 22 RAID O data striping S1 S4 of data blocks B1 B12 For data in the array to be readable the data block sequence within each stripe must be the same This sequencing process is performed by the array controller which sends the data blocks to the drive write heads in the correct order A natural consequence of the striping process is that each hard drive in a given array will contain the same number of data blocks Note If one hard drive has a larger capacity than other hard drives in the same array the extra capacity is wasted because it cannot be used by the array NAS 2000s Administration Guide Storage Management Overview Logical Drives LUNs As previously stated drive array technology distributes data across a series of individual hard drives to unite these physical drives into one or more higher performance arrays Distributing the data allows for concurrent access from multiple drives in the array yielding faster I O rates

It is possible to recover from all of these scenarios by accessing shadow copies There are separate steps for accessing a file compared to accessing a folder As documented previously the use of the snapshots are from the network and are based on shares created on the NAS server On Windows 2000 SP3 clients snapshot access is not fully functional at the share point of the network drive At the sharepoint a file or folder that is deleted cannot be recovered directly It is recommended that end user files exist under a folder below the share point to ensure easy recovery of their contents and that the file folders not be removed Therefore recovery is broken out into two categories sharepoint and non sharepoint This behavior is not evident in Windows XP or Windows 2003 clients NAS 2000s Administration Guide Shadow Copies Recovering a Deleted File or Folder non sharepoint or Windows XP Windows 2003 To recover a deleted file or folder within a folder 1 Navigate to the folder where the deleted file was stored 2 Position the cursor over a blank space in the folder If the cursor hovers over a file that file will be selected 3 Right click the mouse and select Properties from the bottom of the menu Select the Previous Versions tab 4 Select the version of the folder that contains the file before it was deleted and then click View 5 View the folder and select the file or folder to recover The view may be navigated multip

NAS devices include m File server consolidation As businesses continue to expand their information technology IT infrastructures they must find ways to manage larger environments without a corresponding increase in IT staff Consolidating many servers into a single NAS device decreases the number of points of administration and increases the availability and flexibility of storage space m Multiprotocol environments Some businesses require several types of computing systems to accomplish various tasks The multiprotocol support of the NAS 2000s allows it to support many types of client computers concurrently m Protocol and platform transitions When a transition between platforms is being planned the ability of the NAS 2000s to support most file sharing protocols allows companies to continue to invest in file storage space without concerns about obsolescence For example an administrator planning a future transition from Windows to Linux can deploy the NAS 2000s with confidence that it can support both CIFS and NFS simultaneously assuring not only a smooth transition but also a firm protection of their investment m Remote office deployment Frequently branch offices and other remote locations lack dedicated IT staff members An administrator located in a central location can use the WebUI of the NAS 2000s Microsoft Terminal Services and other remote administration methods to configure and administer all aspects of the NAS 2000s

S system administrators can make it easy for users to access and manage files that are physically distributed across a network Users do not need to know and specify the actual physical location of files in order to access them For example if documents are scattered across multiple servers in a domain DFS can make it appear as though the documents all resides on a single server This eliminates the need for users to go to multiple locations on the network to find the information Each DFS namespace requires a root A DFS root is a starting point of the DFS namespace The root is often used to refer to the namespace as a whole A root maps to one or more root targets each of which corresponds to a shared folder on a server A root is implemented as a shared folder on the DFS server A distributed file system can be implemented as a stand alone root distributed file system or as a domain root distributed file system The type of a distributed file system determines which client computers can access the distributed file system A stand alone DFS root m Does not use Active Directory to manage DFS m Cannot have more than one root on a server m Does not support automatic file replication using the File Replication service FRS m Is not fault tolerant and if the root fails the entire namespace will collapse A domain DFS root m Must be hosted on a domain member server Has its DFS namespace automatically published to Active Directory Can h
