Second generation American Dynamics iSCSI and Fiber RAID

Storage

The second generation American Dynamics iSCSI and Fiber RAID Storage solutions are designed

for high-performance recording devices. They are secure and highly scalable storage solutions

that provide SAN storage for virtually any network and application.

The new Rack Mount models are available in a variety of configura

tions and capacities. There are

iSCSI RAID, 4Gb Fiber RAID, and Expansion models which have been uniquely designed to

utilize the same 3U chassis. These storage solutions come standard with redundant power

supplies and fans, and nearly every component is hot-swappable, including sixteen lockable hot-

swap drives. An optional battery backup module is also available for the iSCSI and Fiber RAID

units.

Storage Strategy for FRS/FES RAID Device

Recommendations

• The FRS/FES supports a maximum of eight (8) Disk Groups (aka RAID sets).

• Each Disk Group can be “carved up” into one or more V

irtual Disks (aka Volumes or LUNs). It is

recommended to try to maximize each virtual disk size.

• It is recommended that Virtual Disks from a single Disk Group are all assigned to the same NVR

orage Set. This will eliminate the possibility of unnecessary disk thrashing caused when the

same set of physical disks (DGs) are being used by different sets of cameras (aka Storage

Sets).

• Verify that you have the latest firmware patch or upgrade for your controller.

• Make sure to leave a minimum of a 2U space between storage units.

• Start the camera’s recording after all the drives have

bee

n formatted and their status is “Normal”.

Connecting Additional Storage Devices

Connecting NVR to FRS/FES Using Fiber

Before configuring external storage you must stop NVR Services. Refer to Procedure 20-2 Stop

NVR Services on page 232.

Once you have connected and configured external

storage devices, you must restart the NVR

Services. Refer to Procedure 20-1 Restart NVR Services on page 232.
