The following sections will provide information surrounding the various VR-N100U supported devices.
5.1.
Hard Disk Drive Specifications
VR-N100U supports onboard RAID to offer data integrity for the captured video. The recommended VR-N100U hard drives
should meet the following criteria:
Form Factor
3.5” half-height required
Interface
ATAPI 40-pin ATA/100 or ATA/133
Maximum rpm
7200 or faster preferred
Quickest Seek Times
9ms or faster preferred
Maximum Cache
8MB or higher preferred
Drive Setting
MASTER
required
Brand
Maxtor and Seagate preferred, and always use same make/model for the RAID set
NOTE1: In some instances, VR-N100U has been forced to utilize the slower 5400 rpm rated hard drives due to the lack of
available drive models supporting the above specifications from the leading drive manufacturers.
NOTE2: VR-N100U has the ability to expand the video storage capacity by utilizing the onboard LVD160 SCSI.
5.1.1. Configuring the Hard Drives
When the hard drives are first recognized by VR-N100U as new storage devices, it will prompt the user to configure the drives.
If multiple drives are recognized, the available RAID configuration options will be prompted. Since VR-N100U appliances are
normally preconfigured with four (4) of the same make/model recommended hard disk drives, the user does not have to worry
about configuring the hard drives. However, if for any reason, one or more drives are not configured, you had to add/remove a
device, or delete/recreate the RAID, follow the instructions on the
Devices
section under the
System
Administration Utilities
page.
