The Common Internet File System is a protocol that defines a standard for client systems to request file services from server systems over a network. CIFS is based on the Standard Server Message Block (SMB) protocol, which is widely used by personal computers and workstations running a vast variety of operating systems.
The Common Information Model is an object-oriented model that provides a conceptual framework for describing management data.
COM 1 is the name of the serial communications port on the SpinServer that is used to access the command line interface of the SpinServer.
COM 2 is the name of the serial communications port on the SpinServer that is used to attach the SpinServer to the UPS.
A Dual In-line Memory Module is a small circuit board that holds memory chips.
The command line interface is the command version of the SpinServer management interface software.
Fibre Channel is a set of standards, completely developed through industry cooperation, for a serial I/O bus capable of transferring data between two ports at up to 100 MB/second. Fibre Channel supports point-to-point, arbitrated loop, and switched topologies.
Gigabit is a unit of measure for data transfer rates between two entities on a network. In this context, it refers to one billion bits. Network data transfer rates are often measured in gigabits per second (Gbps).
Gigabyte is a unit of measure for data storage on computer systems. One gigabyte (GB) is equal to 1,024 megabytes (MB).
Gigabit Interface Converters are transceivers that convert between electrical signals used by host bus adapters (and similar Fibre Channel and Ethernet devices) and either electrical or optical signals suitable for transmission.
Gigabit Ethernet is a group of Ethernet standards in which data is transmitted at 1 Gb per second.
The Graphical User Interface is the graphical browser version of the SpinServer management interface software.
Host Bus Adapter is an I/O adapter that connects a host I/O bus to a computer's memory system.
Hypertext Markup Language is the authoring language used to create documents that can be displayed on a web browser page.
Internet Control Message Protocol is an extension to the Internet Protocol (IP). ICMP supports packets containing error, control, and informational messages.
Inodes are data structures that contain information about files in UNIX file systems. In the file system where each file resides, each file has an inode and is identified by an inode number (i-number). Inodes provide information on files, including user and group ownership, access mode (read, write, or execute permissions) and type. Inodes are created when a file system is created. There are a set number of inodes, which indicates the maximum number of files the system can hold. A file's inode number can be found by using the ls -i command.
Input/Output is used to describe any program, operation or device that transfers data between a computer and a peripheral device.
Internet Protocol specifies the format of packets (datagrams) and the addressing scheme. Most networks combine IP with a higher-level protocol, such as TCP or UDP, which establishes a virtual connection between a destination and a source.
Just a Bunch of Disks is a storage subsystem using multiple independent disk drives that are not configured according to the RAID system. The expansion disk enclosure in a SpinServer system is a JBOD enclosure.
Kerberos is a network authentication protocol developed at the Massachusetts Institute of Technology. Kerberos uses encryption keys to provide authentication for client/server applications. Authentication provides verification of a user's or process's identity to a server.
A light-emitting diode is an electronic device that lights up when electricity is passed through it.
Megabit is a unit of measure for a volume of data storage. 1 Mb = 1,024 kilobits (Kb). It is also used to describe data transfer rates on a network. In this context, it refers to one million bits. Networks are often measured in megabits per second (Mbps).
Megabyte is a unit of measure for data storage on computer systems. One megabyte is equal to 1,048,576 (2 to the 20th power) bytes of data.
Megahertz is the unit of measurement of the speed of microprocessors, called the clock speed. One MHz represents one million cycles per second.
Network Data Management Protocol defines a common architecture for the way heterogeneous file servers on a network are backed up. The protocol allows the creation of a common agent used by the central backup application to back up different file servers running different platforms and platform versions.
Network File System is a client/server application that allows all network users to access shared files stored on computers of different types.
Network Interface Cards are expansion boards that enable network connections for a PC or server.
Network Information Service provides a simple network lookup service consisting of databases and processes. Its purpose is to provide information that needs to be available to the entire network, such as login names, passwords, home directories, and group information.
Network Information Service Plus was designed to address security problems that NIS cannot address. (There is no relation between NIS+ and NIS. The commands and the overall structure of NIS+ are different from NIS.) NIS+ increases security by using an additional authentication method. Users have a standard login password, which gives them access to the system, and an additional secure or network password.
NetLanMan is an authentication mechanism used by CIFS.
Non-Volatile Random Access Memory is a type of memory that retains its contents when the power is turned off.
Portable Document Format is a file format developed by Adobe Systems that provides an electronic photocopy of a document. PDF captures formatting information from a variety of desktop publishing applications, making it possible to send documents electronically and have them appear on the recipient's monitor, or in printed form, as the writer intended the documents to appear. To view a file in PDF format, you need Adobe Acrobat Reader, a free application distributed by Adobe Systems.
Power Distribution Units are appliances that provide power connections to system components with high voltage requirements.
In Kerberos, a principal is a unique identity to which Kerberos can assign tickets. An example Kerberos principal is susan/admin@SECURITY.EXAMPLE.COM.
Redundant Array of Independent Disks is a disk enclosure with RAID controllers. The SpinServer supports RAID levels 0, 1, 3, 5, and 0+1. A RAID set is a group of disks in which the disks independently operate, the data strip size is no smaller than the exported block size, and parity check data is distributed across the array's disks.
Small Computer System Interface is a parallel interface standard used by computer systems for attaching peripheral devices, such as disk drives and printers.
The SCSI Enclosure Services manager reports the operational status of disk drives to the RAID controllers.
The Simple Network Management Protocol is a protocol for monitoring and managing devices on a network.
A Storage Pool is the logical view, as it appears to users, of the compartmentalization of physical storage disks.
In Kerberos, a Service Principal Name is the name by which a client uniquely identifies an instance of a service.
Secure Shell is a program used to log into another computer over a network to securely execute commands from a remote machine, and to move files from one machine to another. It was developed by SSH Communications Security Ltd.
Transmission Control Protocol is a transport protocol. Where the UDP protocol handles only packets, TCP enables two hosts to establish a connection and exchange streams of data. TCP is more reliable than UDP, but slower.
U specifies one unit of height in an equipment rack. 1 U = 1.75 inches = 4.45 cm.
User Datagram Protocol is a connectionless protocol that runs on top of IP networks, as does TCP. Unlike TCP, UDP provides very few error recovery services, offering instead a direct way to send and receive datagrams over an IP network. It is used primarily for broadcasting messages over a network. UDP is faster than TCP, but less reliable.
An Uninterruptible Power Supply is an appliance that provides power security, with battery power, in the event of a power failure.
A Virtual File System is the primary unit of data storage in the SpinServer system.
The Windows Internet Naming Service supports network clients and servers running Windows operating systems. WINS uses a distributed database that is automatically updated with the names of computers currently available on a Windows Network and the IP address assigned to each one. The SpinServer has the ability to register its CIFS servers with the WINS servers that are defined in the SpinServer system.
