Data corruption occurs when a bit or a set of bits is changed unintentionally due to variety of reasons: hardware errors, data transfer noise, software bugs, many more … The probability of a silent data corruption occurring is proportional to the number of writes being done. A heavy write-intensive application such as video surveillance recording is more exposed than an average email server. Silent data corruption happens more often than you think, - CERN study found 1 in every 1500 files to be corrupted. It can be potentially devastating, - up to 10% of catastrophic storage system failures have been linked to silent corruption of data , according to white paper by NEC. Next generation file system with built-in per-block checksumming, self-healing error correction and atomic copy-on-write snapshots will protect your mission critical surveillance recordings against silent data corruption.

CORRUPTION
In Video Surveillance Storage

2. WHAT IS DATA CORRUPTION?
Data corruption occurs when a bit or a set of
bits is changed unintentionally due to variety of
reasons:
Hardware errors
Data transfer noise
Software bugs
Many more …

3. WHY VIDEO SURVEILLANCE?
The probability of a silent data corruption
occurring is proportional to the number of writes
being done.
A heavy write-intensive application such as
video surveillance recording is more exposed
than an average email server.

4. HAPPENS MORE OFTEN THAN YOU
THINK
CERN study found 1 in every 1500 files to have
data corruption.

5. CAN BE POTENTIALLY
DEVASTATING
Up to 10% of catastrophic storage system
failures have been linked to silent corruption of
data, according to white paper by NEC.

6. END-TO-END CHECKSUMS
Unlike a simple disk block checksum, end-to-end
256-bit checksum, stored as metadata
separate from the data it relates to, will detect
all forms of silent data corruption such as
misdirected reads and writes, phantom writes,
DMA parity errors, driver bugs and accidental
overwrites as well as traditional "bit rot."

7. COPY-ON-WRITE
When data is changed, blocks containing active
data are never overwritten — the data is always
written to a new block and checksummed,
ensuring that data is always consistent on the
disk.

8. NEXT GENERATION FILE SYSTEM WITH
BUILT-IN PER-BLOCK CHECKSUMMING,
SELF-HEALING ERROR CORRECTION
AND ATOMIC COPY-ON-WRITE
SNAPSHOTS WILL PROTECT YOUR
MISSION CRITICAL SURVEILLANCE
RECORDINGS AGAINST SILENT DATA
CORRUPTION.
