General Enterprise Storage
What is Software-Defined Storage?
These days anything seems to be software defined. So what does software-defined storage or software storage really mean?
What is Unified Storage?
Unified storage refers to storage systems that make data accessible via multiple protocols. Some of these protocols include NFS, SMB, HDFS and others.
The Battle is On: SAN vs. NAS vs. Object
Enterprise storage systems are divided into three categories today: SAN, NAS and Object.
File Storage vs. Object Storage: What’s the Difference and Why it Matters
The main differences between file and object storage are the access protocol, performance, scalability, and the consistency guarantees they offer.
What is the Network File System (NFS)?
The NFS protocol was designed to allow several client machines to transparently access a file system on a single server.
What is a POSIX File System?
The POSIX standard describes how system calls must behave, and to what degree one section defines the semantics (behavior) of a POSIX compatible file system.
What is a Parallel File System?
The term parallel file system is often used in two ways: The ability to do IO in parallel to multiple servers, and specific IO patterns of parallel HPC applications.
What is a Distributed File System (DFS)?
A DFS, as the name suggests, is a file system that is distributed on multiple file servers or locations. Its primary purpose is to reliably store files.
Understanding NAS Consolidation and Its Benefits
NAS consolidation refers to the process of replacing several NAS systems with a unified, more efficient system that behaves like a virtual system.
Scalability of File Systems
What is a Scale-Out File System or Scale-Out NAS?
Scale-out refers to the ability of a system to scale certain dimensions when you add more components. In a storage or file system - sometimes also called scale-out NAS - these components are hard drives (hard disk, NVMe) and servers.
What is High-Performance Computing Storage?
High-performance computing (HPC) is the field of IT that deals with solving large - often scientific or research problems - using large supercomputers or compute clusters; In other words, by aggregating computing power of many machines.
What is HDFS, the Hadoop File System?
Hadoop Distributed File System (HDFS for short) is the primary data storage system used by Apache Hadoop applications as a means for managing pools of big data and supporting related big data analytics applications.
Data Protection in Storage Systems
RAID, EC, Replication: Data Protection in Storage Systems
Data protection is the process of safeguarding important information from corruption, compromise or loss using technologies like RAID, Erasure Coding or Replication.
Storage for Kubernetes
What Are Containers? An Introduction to Containerization
Containers are composed of container images as a method to package software and its dependencies, namespaces for resource isolation, and Linux kernel cgroups for resource limits, such as CPUs, and RAM.
What Is Kubernetes and How It Works
Kubernetes, also known as k8s, is an open-source container orchestration system that allows you to automatically manage containerized workloads and services.
How to Choose the Best Kubernetes Storage?
Application storage is essential to Kubernetes. It helps you keep your data safe whenever a container crashes, and allows you to share files between containers running in the same Pod.
Get familiar with Kubernetes terminology, such as Persistent Volumes, Storage Classes, CSI Plugins, etc.
