Object Operations
The SMI-S specifications, to which VSP G1000 conforms, define the interfaces for devices that make
up a storage network, such as storage subsystems, virtual storage systems, switches, and hosts. The
features that need to be provided by the management service to manage the devices are grouped in
a profile for each device. The profiles used by the CIM/WBEM features of VSP G1000 are the Array
profile and its subprofiles. The Array profile defines the interfaces for storage subsystems.
Indications
The indication feature is the event notification feature defined by CIM. When an event occurs in a CIM
server, the CIM server reports the indication instance, which shows the information about the event
(such as generation or deletion of a CIM instance), to CIM clients. For a CIM client to receive
indications, its location and transmission conditions for indications must be registered in the CIM
server beforehand. For details on how to register, see the SNIA website.
VSP G1000 reports the occurrence of the following events:
•
Generation of a volume
•
Deletion of a volume
•
Allocation of a path
•
Cancellation of a path
Service discovery
VSP G1000 provides the service discovery feature based on the Service Location Protocol (SLP).
The SLP is undergoing standardization by IETF and provides a way to discover desired services
available in a network. For details on the SLP, see RFC2608.
By specifying the type of service, SLP clients can obtain information (such as URLs) about how to
access the available services, and information about service attributes.
In VSP G1000, the VSP G1000 server uses the SLP to report information about the WBEM Service.
(3) VSP G1000 CIM Models
The CIM/WBEM features provided by VSP G1000 support the CIM models for the profiles and
subprofiles specified in SMI-S.

Name Description Figure
Array profile
Provides information about the basic components of a storage subsystem such as
storage volumes and ports as well as the relationship between the components and
the storage subsystem.
Figure 2-1
Physical Package Provides a general-purpose object model representing the physical attributes of the
managed devices, independent of profiles.
