Gartner differentiates object storage from distributed file systems, and have published separate Critical Capabilities reports for each. The last Critical Capabilities for object storage was published March 31, 2016. In this report, written by Gartner analysts, Arun Chandrasekaran, Raj Bala and Garth Landers, Gartner recommends that readers of the report “Choose object storage products as alternatives to block and file storage when you need huge scalable capacity, reduced management overhead and lower cost of ownership.” We believe the use cases for object storage and block and file systems are quite different.
This report clearly showed Hitachi Vantara’s HCP in a leadership position for object store
Then in October of 2016, Gartner combined object storage and distributed file systems into one Magic Quadrant (MQ) report, and as stated in the 2017 report, Gartner defines distributed file systems and object storage as software and hardware solutions that are based on "shared nothing architecture" and support object and/or scale-out file technology to address requirements for unstructured data growth. However, they still recognized the difference in these two technologies in their research.
“Distributed file system storage uses a single parallel file system to cluster multiple storage
nodes together, presenting a single namespace and storage pool to provide high bandwidth for
multiple hosts in parallel. Data is distributed over multiple nodes in the cluster to deliver data
availability and resilience in a self-healing manner, and to provide high throughput and
“Object storage refers to devices and software that house data in structures called "objects," and serve clients via RESTful HTTP APIs..”
On October 17th, Gartner published their second annual " Magic Quadrant for Distributed File Systems and Object Storage." For the second year in a row, we are the only vendor in the Challengers quadrant since we were only evaluated on our HCP object storage. It is important to note that the Magic Quadrant report is NOT a stand-alone assessment of object store. As the title states, this is a vendor-level analysis based on the COMBINATION of an Object Storage and Distributed File Systems offering.
A new Critical Capabilities for object storage is expected to be published in early 2018. We believe that report will be a more accurate way to evaluate object storage systems. We would expect to score much higher due to the addition of geo-distributed erasure coding and other functionalities in HCP, as well as the addition of Hitachi Content Intelligence to the HCP portfolio.
