Recorded audio from the Peer Incite:
As storage systems scale to multi-petabytes, RAID is becoming a less viable long term solution. Bit error rates (BER) of conventional disk drives run in the 10E14 or 10E15 range. A 10TB drive will be 10^14 in capacity, approaching the crossover point. At the crossover point, drive failures are not just statistically possible but they become probable. In addition, drive rebuild times are becoming increasingly elongated. In the early 1990’s it took one minute to rebuild a drive. A 2TB drive can take 8 hours or more to rebuild. Within the next six years we will see 30TB disk drives which, if nothing changes will take nearly a month or more to rebuild. With such long rebuild times, the chance of multiple drive errors, which today is very slight, increases dramatically. On top of all this, we are seeing increased popularity of encryption, deduplication and compression meaning the loss of a single bit makes all the data on a drive unrecoverable.
At the next Peer Incite we’ll be joined by Chris Gladwin, technical expert, visionary, founder and CEO of Cleversafe. We’ll also be joined by other industry experts to discuss the following key issues:
- What do we mean by RAID?
- Why is parity-based RAID becoming a less viable system of data protection?
- What are vendors doing to solve the BER problem?
- Which emerging technologies will prevail?
- How should users protect themselves from permanent data loss?
