4.3. Hard Drives Installation
Hard disk drives are purchased separately. When selecting hard disk drives (HDD), HDD
manufacturers always urge users to choose enterprise/surveillance grade drives for
24/7 surveillance operations to ensure system stability. The surveillance hard drives
on our Approved Vendor List (AVL) are engineered to work continuously, withstand
high-temperature fluctuations and equipment vibrations found in any typical
surveillance application. To reduce errors occurred on your RAID data and the chance
of the recording performance being affected, it is highly recommended to use HDDs
listed on our Approved Vendor List (AVL) to ensure reliability. Find the AVL on our web
page: http://www.surveon.com/support/hardware.asp
4.3.1. Prerequisites
Hard drives are separately purchased and when purchasing hard drives, the
following factors should be considered:
Capacity (MB/GB): Use hard drives that have the same capacity and rotation speeds.
RAID arrays use a “least-common-denominator” approach meaning the maximum
capacity used in each drive for comprising a logical configuration is the maximum
capacity of the smallest drive.
Drive Interface Type: The enclosure accommodates SATA-II or SATA-III hard drives.
Note: The hard drives and drive trays should only be installed into the system after it
has been mounted into a rack cabinet. If the hard drives are installed first, the
system will be too heavy to handle and the possible impact during installation
may damage your hard drives.
Users MUST install at least ONE hard drive into slot 1 to setup the system. It is
strongly recommended to install at least TWO hard drives upon initialization!
