IBM Storage® Scale Erasure Code Edition
(ECE) provides IBM Storage Scale RAID as software and
it allows customers to create IBM Storage Scale
clusters that use scale-out storage on any hardware that meets the minimum hardware requirements.
All the benefits of IBM Storage Scale and IBM Storage Scale RAID can be achieved by using existing
commodity hardware.
IBM Storage Scale Erasure Code Edition provides the
following features:
Reed Solomon highly fault tolerant declustered Erasure Coding that protects against
individual drive failures and node failures.
Disk Hospital to identify issues before they become disasters.
End-to-end checksum to identify and correct errors that are introduced by network, media, or
both.
Fast background disk rebuilds in minutes without affecting application performance.
HDFS Transparency version 3.1.0-3 and later allows the Hadoop or Spark applications to access the
data stored in IBM® ECE.
Note: The ECE storage
must be configured as shared storage to be used in the Hadoop
environment.
