<strong>About</strong> the RAID 6+2 Configuration<br />

System Installation with ContentServer 3000 Series<br />

In a RAID 6+2 configuration, the disk drives are configured in a Dual Parity (DP) RAID array,<br />

ensuring that the system can continue to function despite the failure of any two disk drives. This<br />

configuration optimizes storage capacity at the cost of bandwidth.<br />

<strong>About</strong> the RAID 2+1 Configuration<br />

In a RAID 2+1 configuration, the drives are configured with a single parity disk drive and a hot spare.<br />

This configuration optimizes bandwidth at the cost of storage capacity.<br />

<strong>About</strong> Site Preparation<br />

Note the following prerequisites for installation of your <strong>Omneon</strong> <strong>MediaGrid</strong> System.<br />

Preparing the Site<br />

Note the following prerequisites for installation of a <strong>Omneon</strong> <strong>MediaGrid</strong> storage system:<br />

• Environmental<br />

<strong>Omneon</strong> equipment is designed to operate in a clean, air-conditioned control room environment.<br />

Care must be taken to avoid temperature and humidity extremes.<br />

• Power<br />

When connecting equipment, care must be taken to avoid power lines that are subject to noise and<br />

voltage spikes. Do not install units on a power circuit that is common to such equipment as air<br />

conditioners and refrigeration units. For optimum protection, AC noise filters and surge<br />

protectors are recommended if unstable power conditions are present.<br />

• Site<br />

The ContentServer 3000 and ContentStore 3160 each weigh approximately 75 pounds (34 kg.)<br />

with all disk drives installed.<br />

<strong>Omneon</strong> <strong>MediaGrid</strong> equipment is designed for rack mounting. Refer to Rack Mounting a<br />

<strong>MediaGrid</strong> System with the ContentServer 3000 for recommendations on how to mount the<br />

<strong>Omneon</strong> <strong>MediaGrid</strong> components.<br />
