Chapter 3 Customizing Your Snap Server Your Snap Server is configured so that you can use it immediately in its default condition. Or, you can also customize the server to your own specifications.
Reclaiming Snapshot Space Reclaiming Snapshot Space A Snapshot is a single point-in-time image that is taken of a volume. It can then be used to back up the volume without interfering with activity on the live volume. In the event of corruption, it can also be used to restore the volume or files on the volume to the snapshot state. All Snap Servers are configured with 20% of the default volume set aside for snapshots.
Changing Disk Configuration the RAID if desired. However, be aware that deleting the default volume may also disable some third party applications that reside on the volume. Note Before reconfiguring the volume space, be sure to review the Volumes topic in the Admnistration Tool’s online Help. To modify your RAID configuration, navigate to Storage > Storage Guides in the Administration Tool. The RAID wizard will step you through the process of making volume and share modifications.
Creating Shares The RAID wizard will step you through the process of configuring the RAID, volumes, and shares. Note Before reconfiguring volume space, be sure to review the Volumes topic in the Admnistration Tool’s online help. Creating Shares Your Snap Server is pre-configured with one volume (VOLO) and one share (SHARE1).
Setting Up Security Setting Up Security To control who can access the files and folders stored on the server, you must set up security restrictions. To set up security on your server, use the settings on the Security menu in the Administration Tool. Caution The default configuration allows all users on your network full access to all disks on the server. If you have Web access enabled, this could include Internet users as well, depending on your network setup.
Setting Up Security Default Local Users and Groups AllLocalUsers The AllLocalUsers group account includes all local users created on the Snap Server. AllUsers The AllUsers group account includes all local, Windows domain, and NIS users. admingrp The admingrp account includes the default admin user account. Any local user accounts created with admin rights are also automatically added to this group.
Setting Up Security Assigning User Access Access to Network Shares Network shares are virtual folders that map to an actual directory on the server. They are equivalent to Microsoft networking shares, Macintosh networking shared folders, and NFS exported file systems. Snap Servers are configured at the factory with one share for the default volume and RAID. You can create additional shares that represent an entire disk or a folder within a disk by clicking Security > Shares, then clicking New.
Setting Up Security for a user (or group), select the user or group whose access you wish to modify, select the new permissions level from the drop down list, click the Change Access button, then click OK. To assign access permissions to files and folders within a share (Windows NT, 2000, and XP): 1 In Windows Explorer, right-click the folder or file to which you want to assign permissions, select Properties, and select the Security tab. 2 Add or remove users and groups, and assign permissions to each.
Setting Up Security To assign disk usage quotas: 1 Navigate to Storage > Quotas in the Administration Tool. If the Enabled link is Yes, continue to the next step. If the link is No, click the link, then click to put a check in the Enable Quotas on Volume [xxxx] box. You can also define a default quota from this screen. 2 Click the volume on which you want to assign quotas. The server displays a list of users along with their current disk space allocation and consumption.
Setting Up Notification via Email Setting Up Notification via Email When certain events occur, an email notification can be sent to the administrator. To configure this feature, do the following: 1 From the Administration Tool, select Server > Email Notification. 2 Click to put a check in the Enable Email Notification box. 3 Fill in the IP Address of the server, the email address of the sender, and the email addresses of people you want to receive the notifications.
Adding SnapExtensions Adding SnapExtensions SnapExtensions are software applications, agents, and utilities that extend the capabilities of a Snap Server. Some SnapExtensions are fully functional out-of-thebox; others may require a download and/or the purchase of a license for full operation. For up-to-date information on feature availability, contact Adaptec. Note Licenses can be obtained by clicking the License required link next to the specific item on the SnapExtensions screen.
Setting up Data Protection Schedules Feature Description iSCSI Internet SCSI (or iSCSI) is an iSCSI disk located on a Snap Server volume which appears to a client machine as a local SCSI drive. This storage virtualization frees the administrator from the physical limitations of direct-attached storage media on network clients or servers, allowing capacity to be expanded easily as needed. A separate license is required.
Using your Snap Server as a Print Server Creating a Disaster Recovery Image Create a disaster recovery image (DRImage) on the Maintenance > Disaster Recovery page. This DRImage should be created after the server configuration is complete, and can be used to recover the server or a replacement server to the configured state. Review the Disaster Recovery topic in the online Help for more detailed information.
Using your Snap Server as a Print Server 5 Give the printer a name, and complete Desciption and Location information as desired. Click OK. The printer will appear in the list on the main printing page. Adding the Network Printer to the Client The Snap Server supports both Windows SMB (SAMBA) and IPP printing protocols. Note To make printer drivers easily accessible to users, copy them to a share which everyone can access on the Snap Server.
Using your Snap Server as a Print Server Adding the Network Printer to a Linux Client Add a printer using your usual method. If you are using SMB, you will need to know the Snap Server name. If you are using IPP, enter the exact path as follows in the URL field: http://servername:631/printers/sharename where servername is the name or IP address of your Snap Server and sharename is the name of the printer. Note 631 is the IPP port number.
Using your Snap Server as a Print Server Deleting a Printer from the Snap Server When you remove a printer, remember to remove its information from both the Administration Tool and the client machines. 1 Disconnect the printer cable from the Snap Server. 2 In the Administration Tool, navigate to Server > Printing. In the list of printers, the status of printer you just removed should appear as Offline.

Glossary Term Definition access permissions A rule associated with a share, a file, or a directory to regulate which users can have access to the share and in what manner. ACL (Access Control List) The list that controls access to directories and files. Each ACL includes a set of access control entries, which contain the metadata that the system uses to determine access parameters for specified users and groups.
Term Definition autonegotiation An Ethernet feature that automatically negotiates the fastest Ethernet speed and duplex setting between a port and a hub or switch. This is the default setting and is recommended. autosensing An Ethernet feature that automatically senses the current Ethernet speed setting. CA eTrust Antivirus The antivirus software bundled with the Snap Server. CIFS (Common Internet File System) The default Windows protocol for communication between computers.
Term Definition domain name The ASCII name that identifies the domain for a group of computers within a network. Ethernet The most widely installed LAN technology. 100Base-T Ethernet provides transmission speeds of up to 100 Mbps. Fast Ethernet or 1000Base-T provides transmission speeds up to 1000 Mbps and is typically used for LAN backbone systems, supporting workstations with 100Base-T cards.
Term Definition Inheritance In Windows permissions, inheritance is the concept that when permissions for a folder are defined, any subfolders within the defined folder inherit its permissions. This means an administrator need not assign permissions for subfolders as long as identical permissions are desired. Inheritance greatly reduces administrative overhead and also results in greater consistency in access permission management.
Term Definition NAS (Network Attached Storage) Hard disk storage that is set up with its own network address as opposed to being attached to the department computer that is serving applications to a network's workstation users. By removing storage access and its management from the department server, both application programming and files can be served faster because they are not competing for the same processor resources.
Term Definition PoP (Proof of Purchase) The number used to obtain a license key for an upgrade to third-party applications. POSIX (Portable Operating System Interface) A set of standard operating system interfaces based on the UNIX operating system. The need for standardization arose because enterprises using computers wanted to develop programs that could run on multiple platforms without the need to recode. The Snap Server uses Extended POSIX ACLs.
Term Definition restrict anonymous A Windows feature in which anonymous users cannot list domain user names and enumerate share names. Microsoft has provided a mechanism in the Registry called restrict anonymous for administrators to restrict the ability for anonymous logon users (also known as NULL session connections) to list account names and enumerate share names.
Term Definition Snap Server Manager (SSM) A Java-based utility for discovering and monitoring Snap Servers. SnapDRImage The Snap Server disaster recovery image that saves serverspecific settings such as server name, network, RAID, volume and share configuration, local user and group lists, and snapshot schedules. SnapExtension A Java application that extends a Snap Server's functionality. SnapExtensions are produced both by Adaptec and third-party vendors.
Term Definition static IP address An IP address defined by the system administrator rather than by an automated system, such as DHCP. The Snap Server allows administrators to use DHCP-assigned or statically assigned IP addresses. striping A RAID storage technique that distributes data evenly among all disks in the array. subnet mask A portion of a network that shares a common address component. On TCP/IP networks, subnets are all devices with IP addresses that have the same prefix.
Term Definition Windows domain authentication Windows-based networks use a domain controller to store user credentials. The domain controller can validate all authentication requests on behalf of other systems in the domain. The domain controller can also generate encrypted challenges to test the validity of user credentials. Other systems use encrypted challenges to respond to CIFS/SMB clients that request access to a share.
