NFS-enabled share. To Mount Shares from NFS Clients A share on a SnapServer is equivalent to an exported filesystem on an NFS server. NFS users can mount SnapServer shares and access content directly, or mount a subdirectory of a share, using the following procedure: 1.
NIS domains are configured on the Network > NIS page of the Web Management Interface. The SnapServer can join an NIS domain and function as an NIS client. It can then read the users and groups maintained by the NIS domain. Thus, you must use the NIS server to make modifications.
SnapServer’s guest user account and AllUsers group account. You can set share access and file access for anonymous FTP users by modifying permissions for these accounts. For more granular control over FTP access, you must create local user accounts for FTP users.
NOTE: FTP users cannot manage files or folders in the FTP root directory. SNMP Configuration The SnapServer can act as an SNMP agent. SNMP managers collect data from agents and generate statistics and other monitoring information for administrators. Agents respond to managers and may also send traps, which are alerts that indicate error conditions.
SnapServer 7.0 Administrator’s Guide 3 – Network Access Default Traps A trap is a signal from the SnapServer informing an SNMP manager program that an event has occurred. The SnapServer supports the following default traps: Trap Initiating Action coldStart Whenever SNMP is enabled and the server boots.
SnapServer 7.0 Administrator’s Guide 3 – Network Access Option Description Server Location Enter information that helps a user identify the physical location of the server. For example, you might include a street address for a small business, a room location such as Floor 37, Room 308, or a position in a rack, such as rack slot 12.

4 – DynamicRAID Storage Storage Pools If you chose the DynamicRAID option during the initial setup of your SnapServer, a storage pool was also created by the wizard. When you navigate to Storage > Storage Pools , an overview of that storage pool is shown. The SnapServer head unit supports only one storage pool on which multiple volumes can be created.
4 – DynamicRAID Storage Storage Pool Creation During the setup process, the storage pool is created on the SnapServer using all disk drives available. DynamicRAID always maximizes the space available based on the type of parity mode and size requested for the snapshot pool. Should it become necessary to create a new storage pool, click the link in the Status column of the storage pool table to open the page.
SnapServer 7.0 Administrator’s Guide 4 – DynamicRAID Storage To Create the Storage Pool In order to create a new storage pool, you must have at least one empty drive, and the chassis in which the drive is located cannot have a storage pool already present.

In the Duration field, specify how long the snapshot is to be active in hours, days, weeks, or months. The SnapServer automatically deletes the snapshot after this period expires, as long as no older unexpired snapshots exist that depend on it. If any such snapshot exists, its termination date is displayed at the bottom of the page.
Create Snapshot Share. Step 3: Set the backup software to archive the latest version of the snapshot. The SnapServer makes it easy to configure your backup software to automatically archive the most recent snapshot. Simply configure your backup software to copy the contents of the directory within the snapshot share you created.
Snapshot data grows dynamically for as long as a snapshot is active and as long as there is enough space available in the snapshot space to store them. When the snapshot space approaches its capacity (at about 95 percent), the SnapServer deletes the oldest snapshot’s data to create space for more recent snapshot data.

When you install VMware ESX Server or vSphere Server, the iSCSI Initiator is automatically installed. On connecting to the SnapServer targets, the VMware ESX 3.5 Server initiator will find all iSCSI disks and automatically log into them. If iSCSI disks are shared across multiple servers, you can use CHAP authentication to restrict the number of iSCSI disks the VMware initiator can access.
NOTE: If iSCSI is used on a SnapServer with more than one Ethernet port, Mac OS X iSCSI clients can encounter connectivity issues if multiple ports are connected to one or more networks. To avoid these issues, configure the server from Network > TCP/IP to enable and connect only one standalone interface or one bonded pair (Load Balance, Failover, etc.) to a single network.
Page 117
To ensure the fastest possible write performance, SnapServers can buffer up to 1GB of data to efficiently handle data being transmitted to a SnapServer. This widely accepted method of improving performance is not without some risk. For example, if the SnapServer were to suddenly lose power, data still in cache would be lost.
Page 118
Disk Naming Conventions iSCSI disks are assigned formal IQN names. These appear as the iSCSI device names that the user chooses (or types) when connecting from a client initiator to the SnapServer target, and also on the iSCSI Disk details page.
Navigate to Storage > iSCSI and click Create iSCSI Disk to create, edit, or delete iSCSI disks on the SnapServer. Be sure to read “iSCSI Configuration on the SnapServer” on page 6-17 before you begin creating iSCSI Disks. (Traditional RAID uses “Volume”) NOTE: You cannot delete or edit an iSCSI disk until all clients have been disconnected from that disk.
Disabling a write cache for an iSCSI Disk does not disable the write cache for any other iSCSI Disk or any other resources on the SnapServer. No active sessions can be connected to the iSCSI disk when enabling or disabling the write cache.
Windows Server 2008 R2 Backing up an iSCSI Disk using VSS Snapshots. Windows VSS-compatible backup applications can create snapshots of SnapServer iSCSI disks to perform consistent backups of application data without stopping the application, using the snapshot instead of the live volume as the backup source.

To accommodate NFS clients, the SnapServer can also join an NIS domain, and the SnapServer can look up user IDs (UIDs) and group IDs (GIDs) maintained by the domain. For authentication control beyond the guest account, Mac and FTP client login credentials can be created locally on the server.
Web Management Interface. Local users and groups are used for administrative access to the server. A local user or group is one that is defined locally on the SnapServer using the Web Management Interface. The default users and groups listed below cannot be modified or deleted.
UID and GID Assignments The SnapServer uses the POSIX standard to assign UIDs or GIDs, in which each user and group must have a unique ID. This requirement applies to all users and groups on the SnapServer, including local, Windows, and NIS users and groups.

7 – Security Options Shares SnapServer has implemented features to accommodate the different methods used by the SMB and NFS protocols for sharing data. At the share level, administrators can assign read-write or read-only share access to individual Windows (and local) users and groups.
New shares are created by default with full read-write access to all users, subject to the filesystem permissions on the share target directory. The first step to securing a SnapServer is to specify access at the individual share level. Administrators can assign Read/Write or Read-Only share access to individual Windows (and local) users and groups.
Page 136
A snapshot share is a read-only copy of a live share that provides users with direct access to versions of their files archived locally on the SnapServer. Users who wish to view or recover an earlier version of a file can retrieve it on demand without administrator intervention.
Page 137
NOTE: The same share folders appear on the Web View page when you connect to the SnapServer using a Web browser. However, the snapshot share folder does not provide access to the snapshot; it always appear to be empty. You can prevent the snapshot share from displaying on this Web View page by selecting the Hide Snapshot Share option when creating or editing a share.
SnapServer 7.0 Administrator’s Guide 7 – Security Options Create Shares To create a new share, you need, at a minimum, to specify the share name, volume, and folder path. Advanced Share Properties By clicking the Advanced Share Properties link, the additional advanced options are displayed.

If Kerberos is enabled, access is applied uniformly to all Kerberos-authenticated NFSv4 clients connected using the matching Kerberos option. Host-based access as described in The SnapServer Exports File Default Options still applies to NFSv2 and v3 clients when Kerberos is enabled, but it does not apply to NFSv4 clients.
NOTE: Group membership of NFS clients is established by configuring the local client’s user account or the NIS domain. Group membership of SnapServer local users or users ID- mapped to domain users is not observed by NFS clients. Therefore, ACL permissions applied to groups may not apply as expected to NFS clients.
SnapServer 7.0 Administrator’s Guide 7 – Security Options Local Users The Local Users page ( Security > Local Users ) provides all the options to manage local users.

DynamicRAID is a powerful new feature that simplifies storage management and provides additional configuration options not available in Traditional RAID. A SnapServer can be purchased with any amount of initial storage (or number of drives), and more capacity can be added over time by inserting or replacing drives. Volumes can be added and removed at will, and all volumes share the same underlying pool of storage.
How DynamicRAID Works Step 1: DynamicRAID detects all available disk drives on the SnapServer. Step 2: Select the parity setting: • One disk drive – No parity protection only. • Two or Three disk drives – Single parity protection only.
Storage Expansion During the setup process, the storage pool is created on the SnapServer using all disk drives available. DynamicRAID always maximizes the space available based on the type of parity mode and size requested for the snapshot pool. More capacity can be added to a SnapServer over time by inserting or replacing drives, then adjusting Storage Pool properties.
Indicators Drives can be inserted into the SnapServer NAS system at any time unless the user is specifically instructed not to do so. Each drive bay will have an associated indicator which can be either red, amber or green.

Snap EDR provides server-to-server synchronization by moving, copying, or replicating the contents of a share from one SnapServer to another share on one or more different SnapServers. It comes preinstalled on some servers with a 45-day free trial, or it can be downloaded from the SnapServer website.
• Backup and media server IP addresses – Most backup agents need to know the IP addresses of the backup and media servers you plan to use with the SnapServer. Use the Maintenance > Host File Editor page in the SnapServer’s Web Management Interface to supply a host-name-to-ip-address mapping that persists across system reboots.
• Location of the SnapServer backup and restore path – Backup servers often request the path for backup and restore operations on the SnapServer. When you configure a backup server to see the agent or client running on the SnapServer, use the following path: /shares/sharename where sharename is the name of the share to be backed up.
This section explains how to install the CA ARCserve Agent versions 11.5 and 12.0. Consider these important points: • This procedure assumes that you are using the default SnapServer configuration; and you have created a directory called agent (to which to copy your agent/client files) on the default share (SHARE1), such that the path to the directory is /shares/SHARE1/agent.
Uninstall ARCserve Agent 1. If you still have the tar or install directory that you copied to the SnapServer when you installed the ARCserve Agent, the uninstall script will be in that directory. If you do not have the directory or tar, copy the files again from the ARCserve CD or get them from Computer Associates.

Microsoft's MPIO. DynamicRAID™ DynamicRAID is a powerful SnapServer feature that simplifies management of disk additions and replacements in a RAID environment. All RAID and filesystem capacity management is entirely automated. More capacity can be added over time by just inserting or replacing drives.

A strategy that enables one Ethernet port to assume the role of another port if the first port fails. If a port fails on a SnapServer, the second port assumes its network identity (if the two Ethernet cards have been configured for failover). When the port comes back online, the original identities are restored.
Page 253
Front-end See Back-end. Short for File Transfer Protocol. A standard Internet protocol that provides a way to exchange files between computers on the Internet. By default, a SnapServer is set up to be an FTP server. Full-duplex A type of transmission that allows communicating systems to both transmit and receive data simultaneously.
Page 254
SnapServer 7.0 Administrator’s Guide Hidden Share A share that restricts the display of the share via the Windows (SMB), Web View (HTTP/HTTPS), FTP, and AFP protocols. See also SMB. Host Name The unique name by which a computer is known on a network. It is used to identify the computer in electronic information interchange.
Page 255
I/O (Input/Output) The operation of transferring data to or from a device, typically through an interface protocol like CIFS, NFS, or HTTP. The SnapServer presents a filesystem to the user and handles block I/O internally to a RAID array. Short for Internet Protocol. The unique 32-bit value that identifies the location of the server.
Page 256
Local Group/Local User A group/user defined locally on a SnapServer using the Web Management Interface. The local user is defined by the server administrator. Windows domain, ADS, and NIS users are not considered local.
Page 257
SnapServer 7.0 Administrator’s Guide Short for Logical Unit Number. A SCSI or Fibre Channel device identifier. LUN is a subdivision of a SCSI target. MAC Address Short for Media Access Control address, a hardware address that uniquely identifies each node of a network. In the Open Systems Interconnection (OSI) model, one of two sublayers of the Data Link Control layer concerned with sharing the physical connection to the network among several computers.
Page 258
Short for Maximum Transfer Unit. It is the largest size packet or frame, specified in octets (eight-bit bytes), that can be sent in a packet- or frame-based network. Multihomed A SnapServer that is connected to two or more networks or has two or more network addresses. N_port A Node port connects via a point-to-point link to either a single N_Port or a single F_Port.
Page 259
SnapServer 7.0 Administrator’s Guide NL_port A Node Loop port is capable of arbitrated loop functions and protocols. An NL_Port connects via an arbitrated loop to other NL_Port and at most a single FL_Port. NL_Ports handle creation, detection, and flow of message units to and from the connected systems. NL_Ports are end ports in virtual point-to-point links through a fabric, for example NL_Port to F_Port to F_Port to N_Port using a single Fibre Channel fabric switch.

SnapServer 7.0 Administrator’s Guide Permissions A security category, such as no access, read-only, or read-write, that determines what operations a user or group can perform on folders or files. Pool A pool is a collection of RAID disks, grouped together by the RAID storage controller. iSCSI volumes are created from these pools.
Page 261
SnapServer 7.0 Administrator’s Guide RAID Short for Redundant Array of Independent Disks. A data storage scheme where multiple hard drives are combined to form a single logical unit which is highly reliable and gives good performance. Reliability is achieved by mirroring (the copying of data to more than one disk), striping (the splitting of data across more than one disk) and error correction (redundant data is stored to enable faults to be detected and corrected).

(also known as NULL session connections) to list account names and enumerate share names. The implementation of the restrict anonymous mechanism may prevent the SnapServer from obtaining the list of account names it needs to authenticate Windows domain users.
Page 263
SnapServer 7.0 Administrator’s Guide Resynchronization A RAID state that describes the process of integrating a new drive into the RAID. RETMA Short for Radio-Electronics-Television Manufacturers' Association. It is the common name given for a 19-inch distribution frame rack for mounting components.
Page 264
Serial Number The ten-character alphanumeric number assigned by the manufacturer at the factory. Server Number A numeric derived from the MAC address of your SnapServer’s primary Ethernet port that is used to uniquely identify a SnapServer. Session When an initiator wants to establish a connection with a target, it establishes what is known as an iSCSI session.
Page 265
SnapServer 7.0 Administrator’s Guide Snap EDR A SnapExtension that copies the contents of a share from one SnapServer to another share on one or more SnapServers. Snap EDR is designed to work with SnapServers and other SnapServer Storage Solutions. Snapback The process of restoring a logical drive from a selected snapshot.
Page 266
Static IP Address An IP address defined by the system administrator rather than by an automated system, such as DHCP. The SnapServer allows administrators to use DHCP-assigned or statically assigned IP addresses. Storage Area Network See SAN.
Page 268
SnapServer 7.0 Administrator’s Guide Unassigned The state of a disk drive that is seated in a bay but has not been incorporated into a RAID. Unassigned Free Space The controller keeps a map of all the space that is not assigned to any logical drive. This space is available for creation or expansion.
Page 269
A Web-based utility used for configuration and ongoing maintenance, such as monitoring server conditions, configuring email alerts for key events, or for SNMP management. Web View The Web-browser page that opens when users access a SnapServer using their Web browsers, and displays a list of all shares. Windows Domain Authentication Windows-based networks use a domain controller to store user credentials.
