|
||
|
|
Because your data is spread across your disks, it is important that you consider how to protect your data in the event that one of those disks fails. Disk protection provides a means to ensure availability of data stored on disks.</li>

<li class="ulchildlink"><strong><a href="rzalwpower.htm">Plan for power loss</a></strong><br />
|

To ensure that your system is available when you need it, you need to make sure that it has an adequate supply of power, and that it is protected in the event that power is lost.</li>

|
|
<li class="ulchildlink"><strong><a href="rzalwsysman.htm">Use effective systems management practices</a></strong><br />
|
||
|

One of the simplest ways to prevent unplanned outages is to ensure that you are doing everything you can to keep your system running smoothly. This includes performing basic preventive maintenance and systems management tasks that help your system perform at its peak.</li>

|
|
<li class="ulchildlink"><strong><a href="rzalwspace.htm">Prepare the space for your server</a></strong><br />
|

One way to prevent unplanned outages is to ensure that the space where you put your system promotes availability. Many physical and environmental factors contribute to how your system performs.</li>
