After years of collecting
family pictures, videos, and music on our computer, we realized that it would
be a very bad thing if we lost a disk drive with all of our data on it.
To maintain performance while protecting the data from a single drive
failure, a specific technology is used by Home Media
Storage called RAID which is an acronym for Redundant Array of Inexpensive Disks.
RAID level 5 has been selected due to its excellent balance between performance, reliability,
and cost. Our Mediaserver reliability is based on the following:
- RAID 5
redundancy - disk data is automatically backed up
- High quality PC components in widespread use
- Linux operating system stability
- Server concept - software and hardware are kept in a specific configuration and then left alone.
- Advanced cooling
- The server has redundant cooling fans to help keep temperatures down and the system running smoothly.
- Central data
repository - makes backups and restoring data easier

Lines For Maintaining Reliability
Your Mediaserver has been designed to run continuously year after year
with very little care and maintenance. However, there are things that can
happen (fire, flood, etc) that might destroy your data so it is advised
that you make backups of your data on a regular basis. The backups can be
performed using PCs on your home network. One common technique is to burn
data to DVD or Blu-ray media. Usually, you would only backup unrecoverable data. Data on
Music CDs or other similar media wouldn't need to be backed up if you
retain the original copies of the media in a safe location not susceptible to a local disaster. Storing your backup media at
another location is a good idea. Have a friend in another home (perhaps in
a different city) store your backup media.
For quick recovery of files you delete accidentally, you might want to
make online backups of frequently used data. Smaller amounts of frequently
used data are easy to copy to PCs on your home network. Having these copies
readily available for when you do accidentally delete a file, will allow you to restore
the last backed-up copy in minutes. For this purpose, some customers
purchase more than one Mediaserver. One for day to day use and one for
backups.
To help improve reliability you should place your server in a location
that is safe from environmental damage. This includes proximity to water,
flooding, heat, humidity, dust, dirt, smoke, cleaning equipment, etc. There
are stories about businesses who repeatedly had problems with some of their
computer equipment only to find out later that cleaning people were
disconnecting power cords so they could plug in vacuum cleaners etc.
Cleaning equipment can damage wiring and could in fact lead to data loss.
The Mediaserver should be placed well clear of vacuum cleaners, mops and
other hazardous (to the server) cleaning equipment. Keeping your
Mediaserver cool, dry, and free of dust is the best way to extend its life
for years of maintenance free operation.
Keeping your AC power clean is also vital to the
Mediaserver. Brown-outs, black-outs, power spikes, unstable power
lines, lightning etc. can all adversely affect your server. The best
way to smooth over these dirty power conditions is to plug your
Mediaserver into a good quality Uninterruptible Power Supply
(UPS). This is a battery device which senses changes in the AC power
supply and switches to battery power when it senses improper
conditions. It is possible to find a UPS than can supply power to the
server alone for over an hour if a blackout should occur. In
areas where lightning is frequent, you would also want to protect your
telephone lines and perhaps your DSL or Cable modems connected to your
Mediaserver. Your Home Media Storage sales representative can provide
you with more information on UPS technology and options.
Although the Mediaserver is fully capable of performing the duties of
most desktop PCs, its reliability is improved by, essentially, leaving it
alone. Many desktop PCs fail because of frequent changes to settings,
software, hardware, and external cables. By placing your Mediaserver in a
safe location and leaving it alone and accessing it remotely from your
media PCs throughout your home, your Mediaserver will deliver on its
promise of reliability.
