HP Systems Insight Manager - Manual (Page 122)

SLP
SLP enables computers and other devices to find services in a LAN without prior configuration. SLP
is designed to scale from small, unmanaged networks to large enterprise networks.
Profiles
SMI-S is organized around profiles, which describe objects relevant for a class of storage subsystem.
SMI-S includes profiles for arrays, Fibre Channel HBAs, Fibre Channel switches, and tape libraries.
Other storage devices (for example, NAS heads) are expected to be added in the future. Profiles
are registered with the CIM server and advertised to clients using SLP. Systems Insight Manager
determines which profiles it intends to manage, and then uses the CIM model to discover the actual
configurations and capabilities.
SMI-S implementation
SMI-S is implemented with the following components:
•
CIM server (called a CIMOM ), that monitors WBEM requests (CIM operations over HTTP)
from a CIM client, and responds to those requests.
•
CIM provider, that communicates to a particular type of managed resource (for example, HP
MSA arrays), provides the CIMOM with information about the managed resource. In theory,
providers for multiple types of devices (for example, HP MSA arrays and Brocade switches)
can be plugged into the same CIMOM. However, in practice, all storage vendors provide
the CIMOM and a single provider together, and they do not co-exist well with solutions from
other vendors.
The following components can be provided in several different ways:
•
Embedded agent
The hardware device has an embedded SMI-S agent. No other installation of software is
required to manage the device.
•
SMI solution
The hardware or software ships with an agent installed on a host. The agent must connect to
the device and obtain unique identifying information. This is the method used by all HP storage
devices and most SAN devices.

Discovery and identification
Systems Insight Manager discovers storage systems on the LAN and Command View storage device
managers running on managed systems or devices. For internal disks, the Systems Insight Manager
inventory component can identify all drives installed, disk manufacturer, models, disk types, firmware
revision, internal location of the drive in the system, and details about the controllers that manage
the systems. For RAID drives, the RAID type (1 to 5) and manufacturer are discovered in addition
to the details gathered for the internal drives. For SAN systems, Systems Insight Manager discovers
the Command View servers that manage the SAN devices.
