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
HP SIM discovers storage systems on the LAN and Command View storage device managers
running on managed systems or devices. For internal disks, the HP SIM 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, HP SIM discovers the Command View servers
that manage the SAN devices.
HP SIM displays storage systems as follows:
• Internal drives These systems must appear in the Properties pages and the inventory
database as components of their respective systems.
• Tape libraries These devices are identified and included in the All Systems, All Storage
Systems , and All Tape Libraries collections.
• SAN The Command View systems for these devices are identified and available from the
Tools & Links tab of the System Page for the systems serving the Command View systems.
NOTE: HP SIM discovers SAN and NAS management applications and provides user access to
system information when those applications are started.
Using storage solutions
Event collection and launch
To receive events, the Command View software must be configured to send SNMP events to the
HP SIM CMS.
