SNIA SMI union of storage management Storage Management Plan
SNIA (Storage Networking Industry Association),SMI (Storage Management Initiative)
SNIA SMI is a plan to cover the entire configuration, which in order to Bluefin draft specification, development, standardization and drive industry adoption of an open storage management interface.
Bluefin specification is a development milestone for SMI standards, norms modified CIM (Common Information Mode) / WBEM interface (Web Based Enterprise Management), enables users to search through the storage network, manage and monitor a variety of devices.

SNMP Simple Network Management Protocol
1 kinds of networking equipment and state management protocol (PROTOCOL), mode of operation is a message sent by the management system, network equipment, to respond by the AGENT collected management information (MIB) for management systems. Because SNMP is too simple, so the development of RMON specification to replace SNMP.


SOAP Simple Object Access Protocol
SOAP and WSDL, UDDI is used to achieve the three web services (Web services) of the three kinds of XML-based agreements. SOAP primary role is to be a message or information to XML wrapped up, and to be the HTTP transmission. SOAP defines how to create a HTTP Header, and XML files to a computer program can call another computer program, and to transfer data. It also defines how the program is called to respond.
Because the current major platforms such as Windows, Linux, Unix, and J2EE platforms support these agreements, so that messages can be cross-platform transmission, and through the firewall is possible.
In the past has distributed object protocol (distributed object protocols) to provide remote communication between programs, such as Microsoft Distribured Component Object Model (DCOM), CORBA's Internet Inter-ORB Protocol (IIOP) and so on. Very similar to the latter and SOAP. In addition, Sun's Remote Method Invocation (RMI) is used to Java written client / server program agreement between the calls.
