THE SCALABILITY-RELIABILITY DILEMMA

§  Hard Drive Failures are Inevitable •  Drive failures become more frequent with scale simply because there

are more drives to fail. •  For this reason, most scalable NAS systems bring scalability that

comes at the cost of lower data reliability and availability.

§  Hardware RAID Increasingly a Problem for Legacy Storage •  Reliability and availability get worse with scale •  Multi-day rebuild times becoming common •  Odds of encountering sector errors too high, even for RAID 6

§  RAID Solutions Typically Architected for Protection, not Fast Rebuilds •  Long RAID rebuild times lower overall data availability •  Rebuild time determined by the quantity of data to rebuild and the

RAID architecture performance •  Greater risk to production data during rebuild

EVOLUTION OF RAID

6

RELIABILITY AND AVAILABILITY AT SCALE

§  PanFS Delivers Unmatched Data Protection in Software •  Erasure codes protect every file individually −  No hardware RAID, no block-level rebuilds −  Limits rebuilds to affected files, not entire drives

•  RAID 6+ with triple parity protection: 150x improvement over dual parity −  Guards against two simultaneous drive failures and single sector errors on

multiple drives −  Only ~25% capacity overhead and minimal performance impact vs. RAID 5+

•  RAID rebuild performance scales linearly −  Mitigates risk from additional components at scale

•  Randomized distribution of data means increased reliability at scale −  Odds of “one-too-many” drive failures affecting data decrease with scale

7

§  Per-file Distribution Reduces Risk at Scale •  Small files are triple mirrored, large files are striped •  With more and more drives, three drive failures (exceeding fault tolerance)

are less and less likely to affect any given file

One file damaged; Only need to restore File 5

No files damaged; Can rebuild all data

File 1 (small): down 2, rebuild mirror File 2 (small): unaffected File 3 (small): down 1, rebuild mirror File 4 (large): down 2, RAID 6 rebuild File 5 (large): down 3, file damaged!

File 1 (small): unaffected File 2 (small): down 1, rebuild mirror File 3 (small): unaffected File 4 (large): down 1, RAID 5 rebuild File 5 (large): down 1, RAID 5 rebuild

UNMATCHED DISASTER RECOVERY

§  Fast Time to Restore •  Restore specific files instead of entire file system •  Made possible by extra protection of namespace (directory data) in RAID 6+

§  Percentage of Files to Restore Approaches Zero with Scale •  With RAID 6+ (66% small files), a triple simultaneous disk failure means:

Scaling by 10x increases reliability by 1000x!

1 in ~200,000 files to restore

1 in ~200,000,000 files to restore

9

REVOLUTIONARY AVAILABILITY MODEL

§  Extended File System Availability (EFSA) Ensures Business Continuity •  File system remains available when other systems would be down

(even after one-too-many drive failures) •  Directory structure stays navigable and all unaffected files can be

accessed normally •  Only a small number of affected files will be unavailable until restored

from backup

§  Replaces “All Up/All Down” Model of the Past •  Targets an “always on” architecture

SUMMARY

§  IT staff in technical research and enterprise environments need scalable and reliable high-performance storage that is easily managed

§  Selecting scale-out storage usually requires compromises •  High performance computing file systems deliver performance but

compromise on reliability, availability, and ease of management •  Enterprise NAS systems deliver high reliability and availability but

compromise performance

§  Panasas ActiveStor delivers a no-compromise solution
