For the most efficient use of drive space, all drives within an array should have approximately the
same capacity. Each configuration utility treats every physical drive in an array as if it has the same
capacity as the smallest drive in the array. Any excess capacity of a particular drive cannot be used
in the array and so is unavailable for data storage.
•
The more physical drives that there are in an array, the greater the probability that the array will
experience a drive failure during any given period.
•
To guard against the data loss that occurs when a drive fails, configure all logical drives in an array
with a suitable fault-tolerance (RAID) method.
System maintenance tools
Updating firmware
Server and controller firmware should be updated before using the controller for the first time, unless any
installed software or components require an older version. For system software and firmware updates,
download the SPP from the Hewlett Packard Enterprise website (http://www.hpe.com/info/spp/docs).
Installing device drivers
IMPORTANT: Always perform a backup before installing or updating device drivers.
Hewlett Packard Enterprise now distributes drivers and other support software for servers and server
blades through Service Pack for ProLiant, or SPP, which you can download from the Hewlett Packard
Enterprise website (http://www.hpe.com/servers/spp/download). Be sure to use the latest SPP version for
the server or server blade.
If you installed an OS by using the Intelligent Provisioning software, its Configure and Install feature may
have provided the latest driver support.
To directly locate the OS drivers for a particular server, enter the following web address into the browser:
http://www.hpe.com/support/<servername>
In place of <servername>, enter the server name.
For example:
http://www.hpe.com/support/dl360gen8
Managing servers with Insight Agents
When using Insight Agents to manage ProLiant Gen8 servers and later, Hewlett Packard Enterprise
recommends that you clear the selection for Agentless Management Service, and then select Insight
Agents for installation to take place.
You can update the Management Agents by using the latest versions of the agents provided in the
Intelligent Provisioning software.
