HDFS vs. GPFS for Hadoop

Spectrum Scale is an IBM GPFS storage device broadly used for large-scale organization clustered file systems that require petabytes of stockpiling, thousands of nodes, gazillions of files, and thousands of users simultaneously accessing data. Spectrum Scale is compatible with numerous data warehouses and business advanced analytics.

Most conventional Big Data Cluster deployments use Hadoop Distributed File Scheme (HDFS) as the fundamental file system to store information. This blog will review some of the IBM Spectrum Scale information that will enable wide-scale Big Data clusters. Numerous Big Data Architects dismiss these Spectrum Scale features currently not backed by HDFS.

HDFS is not a POSIX complacent file system, whereas Spectrum Scale seems to be.

What Can GPFS on Hadoop Do For You?

If Spectrum Scale is used as the fundamental file system rather than HDFS, all implementations will run as is or with small alterations in a Hadoop cluster. Using GPFS reduces new application code research and deployment costs, and the big data cluster is fully operational in the shortest amount of time.

Spectrum Scale integrates Hadoop clusters with other data warehouse surroundings and easily transfers information between your cluster and Spectrum Scale. This provides a high level of flexibility in integrating your big data surroundings with conventional data processing environments.

Spectrum Scale is a File System with high availability.

Managing large clusters with multiple nodes and petabytes of stockpiling is difficult, and ensuring high availability is critical in such surroundings. Spectrum Scale supports up to three copies of data and metadata, file system reproduction across multiple sites, numerous failure groups, node-based and disk-based quorum, digitalized node recovery, automated data striping and rebalancing, and much more. These highly available characteristics, in my opinion, make Spectrum Scale a wiser option for enterprise production data rather than HDFS.

Compliance with Security

The Role of IBM Spectrum Scale (aka GPFS) in the Enterprise

Another important element for any enterprise is compliance with business important data. However, it is frequently ignored during the development stage of several Big Data Proof of Concepts. Since many Big Data PoCs use a broad range of open-source components, obtaining the necessary security compliance can be difficult. The proof-of-concept implementation cannot go into production unless it meets all protection compliance requirements. When choosing an appropriate file format for Big Data clusters, consider Spectrum Scale’s compliance monitoring characteristics, such as file system encrypted data, NIST SP 800-131A conformance, NFS V4 ACLs assistance, and SELinux compatibility. Spectrum Scale makes it much easier to enact these Operating System Security characteristics than HDFS.

Management of the Information Lifecycle

What is the difference between HDFS and GFS? - Quora

Spectrum Scale includes comprehensive Information Lifecycle Management (ILM) features required when working with complex Big Data clusters with petabytes of stockpiling. Using Spectrum Scale ILM initiatives, aging data can be archived, removed, or relocated to a low-output disc. This is a massive benefit of Spectrum Scale over HDFS in terms of reducing ever-increasing storage costs.

What exactly is GPFS in big data, how does it work, and how does it vary from HDFS?


The IBM General Parallel File System (IBM GPFS) is a file transfer protocol used in many elevated computer technologies and large-scale storage surroundings to distribute and manage content across various servers. GPFS is one of the most widely used file systems for elevated computing (HPC) apps.

The Hadoop Distributed File System (HDFS) is a filesystem built to operate on commodity hardware. It shares many similarities with existing distributed databases. However, the distinction between this and other distributed file systems is very clear. HDFS is a fault-tolerant system that can be deployed on low-cost machines. HDFS could provide high-throughput data access, making it ideal for applications requiring large-scale data sets. To accomplish the target of broadcasting file system data, HDFS relaxes some POSIX restrictions.

HDFS has high fault tolerance and is intended to be deployed on low-cost hardware. It also offers high throughput (high throughput) access to distributed applications, making it suitable for applications with large data sets.

GPFS is a POSIX-compliant filesystem presented by IBM in 1998 that allows any other applications operating on top of the Hadoop cluster to easily access information stored in the operating system.

HDFS is a non-POSIX compliant filesystem that only allows Hadoop applications to access data via the Java-based HDFS API.

Accessing GPFS-resident information from Hadoop and non-Hadoop apps liberates users to create more adaptable big data workflows. For instance, a customer may use SAS to analyze data. They would use a series of ETL stages to deceive data as part of that workflow. A MapReduce program might best carry out these ETL processes.
