RAID Information
What is hot swap? Hot swap is the removing and replacing a defective drive without powering down
the entire server or losing access to the data on the server. The method for hot swapping a drive is
outlined in the user manual. Please follow it carefully to avoid data loss.
What RAID levels are supported?
The unit ships configured for RAID 5. Using the interface you can select RAID levels 0. 1, 1E, 10, 5 and
JBOD. For full explanation of RAID levels please visit our website or locate the User Manual.
What is the default RAID level. The server comes pre-configured with RAID level 5.
How to I upgrade drives? If you wish to replace all the drives the most simple method is to backup
the data, power down the unit, remove all the current drives, install the new drives in the carrier,
power up and restore the data.
A more complex method requires you swap drives one at a time, wait between each swap for a full
RAID re-sync to complete then add the next new drive. You would need to repeat this for all drives.
The advantage to this is that the data is available the entire time. The disadvantage is that the
process is very time consuming and one failure to wait for a RAID re-sync and you will have broken
the RAID set and possibly lost data.
What happens when a drive fails? If you are using the default RAID 5 then your data is protected
from a single drive failure. Just remove the failed drive and put a new drive of the same or larger
capacity in the same slot. A RAID re-sync will bring the drive into the RAID set.
Can I replace a working drive with different drive? Yes, just make sure it is compatible and of the
same or larger capacity. Don’t remove other drives until you are sure the RAID set is complete.
