320 DSView Installer/User Guide
An SNMP manager and external authentication servers, which are optional components and
outside the DSView software system, may also be added to provide additional functionality.
Encryption
Encryption is the translation of data into a secret code. Encryption is the most effective way to
achieve data security. To read an encrypted file, you must have access to a secret key or
password that enables you to decrypt the file. Unencrypted data is called plain text. Encrypted
data is referred to as cipher text.
There are two main types of encryption: asymmetric (also called public-key encryption)
and symmetric.
External authentication server
The external authentication server is an optional component(s) outside of the DSView software
system that enables you to select an authentication method. The DSView software server
brokers authentication requests (LDAP, RADIUS and so on).
Flash
Flash is a special type of EEPROM that can be erased and reprogrammed in blocks instead of
one byte at a time. The BIOS and applications of many modern applications are stored on a
Flash memory chip so that it may easily be updated (if necessary).
FRU (Field Replaceable Unit)
An FRU is a module or component which is typically completely replaced as part of a field
service repair operation.
Graceful shutdown
A graceful shutdown is identical to a shutdown performed by selecting Start - Shutdown and
then selecting Shut down in the Shut Down Window dialog box. In the DSView management
software, a graceful shutdown may be performed on IPMI 1.5 target devices managed by a
DSI5100 appliance.
Hotkey
A hotkey is a keystroke that may be assigned and used to cause a specific action or set of
actions to occur within a user interface. By assigning the action(s), the keystroke’s normal
operation (for example, pressing
F1 to open help) is superseded.
HTML (Hypertext Markup Language)
HTML is a markup language used to create hypertext documents that are portable from one
platform to another on the World Wide Web (WWW). HTML files are ASCII text files with
embedded codes (markup tags) to indicate formatting and hypertext links. Web browsers
interpret and display HTML documents.
HTTP (Hypertext Transfer Protocol)
HTTP is the underlying protocol by which WWW clients and servers communicate. HTTP is
an application-level, generic, stateless, object-oriented protocol for distributed, collaborative,
hypermedia information systems. A feature of HTTP is the typing and negotiation of data
representation, allowing systems to be built independently of the data being transferred.
