Prerequisites: - -Install Minio - [Minio Quickstart Guide](https://docs.minio.io/docs/minio-quickstart-guide) - ## What is Erasure Code? Erasure code is a mathematical algorithm to reconstruct missing or corrupted data. Minio uses Reed-Solomon code to shard objects into N/2 data and N/2 parity blocks. This means that in a 12 drive setup, an object is sharded across as 6 data and 6 parity blocks. You can lose as many as 6 drives (be it parity or data) and still reconstruct the data reliably from the remaining drives. @@ -22,28 +18,13 @@ Bit Rot also known as Data Rot or Silent Data Corruption is a serious data loss Minio's erasure coded backend uses high speed [BLAKE2](https://blog.minio.io/accelerating-blake2b-by-4x-using-simd-in-go-assembly-33ef16c8a56b#.jrp1fdwer) hash based checksums to protect against Bit Rot. -## Deployment Scenarios - -Minio server runs on a variety of hardware, operating systems and virtual/container environments. +## Get Started with Minio in Erasure Code -Minio erasure code backend is limited by design to a minimum of 4 drives and a maximum of 16 drives.
