8516 Hybrid NVR with RAID Installation Guide

Feature Overview
Hard Drives
The unit must contain four hard drives to support RAID.
Hard Drive Details
The unit uses Serial ATA (SATA) hard drive technology.
Each unit has four hard drives. Various drive capacities are available, but each of the four drives
must be the same capacity to support RAID (for example, 4 x 8TB or 4 x 12TB).
The integrated RAID controller offers RAID 5 support.
The unit requires that all four hard drives are in place to support the RAID array.
For information about installing hard drives, see “Replacing Hard Drives” on page 35.
Hard Drive Array - Important Considerations
•
If you have to replace a hard drive in the array, ensure that the replacement hard drive is either
a brand new drive or has been pre-formatted to clear any other data from it. The RAID array
will not rebuild if the replacement disk already contains data.
•
Do not place a RAID formatted hard drive into a non-RAID recorder or a non-RAID investigation
station. You will lose all the data on the RAID hard drive.
•
You cannot rebuild the RAID by replacing a hard drive with a smaller size hard drive. For
example, in a RAID configuration with four 12TB hard drives, you cannot replace one of the
drives with a 10TB hard drive.
•
If a health alert informs you that a RAID hard drive has failed for any reason, replace or fix the
hard drive as soon as possible to avoid losing any data. The RAID configuration requires all four
hard drives, and if more than one drive fails, you can lose all data. RAID Health alerts are
monitored using the Administrator Console software.
