What are Storage Controller Health Status Messages? The DS8K Storage Controller Health Message function sends alerts at the Logical Control Unit (LCU) level when resources are not available or under service. This process runs on both primary and secondary storage systems in a mirrored...
We are excited to announce IBM Spectrum Scale support for Hortonworks Data Platform (HDP) 3.0 . IBM Storage first announced its partnership with Hortonworks for IBM Spectrum Scale storage in Feb, 2017 . Since then, we have continued our joint engineering efforts to certify all releases of IBM...
Decisions about storage are a key element to the success of any artificial intelligence (AI) or deep learning (DL) project, as demands on storage keep growing. For the past few years there has been a huge growth of data โ the โBig Dataโ phenomenon. Now, there are new requirements to support...
The ever expanding and accelerating generation of Big data has made mandatory the usage of more efficient and robust storage filesystems. The data migration across multiple storage mediums is proving to be expensive. There is an inevitable and urgent need to perform inplace data analytics and to...
Background โข Native HDFS supports short circuit read to read data directly from local file system when HDFS client and target datanode are co-located on the same physical node. โข 10% ~ 30% performance gain according to workloads and total reading data size โข HDFS Transparency supports short...
Federation was added to HDFS to improve the HDFS NameNode horizontal scaling. In HDFS transparency, federation is used to make IBM Spectrum Scale filesystems and HDFS filesystem coexist. The Hadoop applications can get input data from the native HDFS, analyze the input and write the output to...
