You can use the Server Snapshot
feature in the UCS SDU user interface to take a point-in-time inventory of a
server. This feature allows you to compare inventories or components of a
server over certain periods of time. Before you initiate a server snapshot, be
sure that you connect a USB flash drive into the server. Without a flash drive
available, the log file created by the server snapshot is not saved.
When you initiate a server snapshot, UCS SDU retrieves information on
the server components, and also runs a series of quick tests to determine the
state of the server. When you initiate a server snapshot, a series of quick
tests such as processor, memory, disk, cache, network interface tests, QPI Link
and Trafffic, LSI Battery backup and RAID adapter tests, and Chipset tests, are
performed on the server.
The time to complete a server snapshot process depends on the server
configuration such as installed memory, the number of physical disks and their
sizes, and the number of network interfaces. This process could complete in
30-45 minutes or could a few hours.
After the server snapshot process is complete, the log file is saved
on to the USB flash drive that you specified. You can open this log file in any
editor, for example, WordPad. To help compare server inventories across time
periods, we recommend that you store these log files in a location and archive
it. When you have multiple log files, you can use a comparison tool from the
Internet to view differences in the server inventory.
