User guide

The DSView management software versions of the spoke server and hub server must
match in order to register the spoke server. For example, you may not register a spoke
server running DSView software version 3.1 with a hub server running DSView
software version 3.2.
DSView software system
A DSView software system includes all the components required to provide DSView
software functionality, including the DSView server, DSView software client, managed
appliances and target devices.
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.
Embedded appliance
Embedded appliances include IBM ASM RSA II, DRAC 4, HP iLO and NEC IPF
embedded appliances.
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
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.
