Introduction

This article describes the deployment of a Ceph cluster in one instance or as it’s called “Ceph-all-in-one”. As you may know, Ceph is a unified Software-Defined Storage system designed for great performance, reliability, and scalability. With the help of Ceph, you can build an environment with the desired size. You can start with a one-node system and there are no limits in its sizing. I will show you how to build the Ceph cluster on top of one virtual machine (or instance). You should never use such scenario in production, only for testing purposes.

The series of articles will guide you through the deployment and configuration of different Ceph cluster builds.

Introduction

The fast-paced world of system administration is growing on a large scale and picking up steam all the time. The migration of business to the cloud we can see these days is a good example of the above said. Thus, the continuous pursuit of a tool that would simplify the life of a system administrator constantly stays on the agenda of the IT world. The main goal behind the development of the Storage Management Initiative (SMI) is eliminating the long journey of finding the right solution.

To simplify the life of system administrators to an even greater extent, the StarWind team has decided to additionally complete the feature set by developing the StarWind Swordfish Provider.

Storage HA on the Cheap: Fixing Synology DiskStation flaky Performance with StarWind Free. Part 2 (Log-Structured File System)
Posted by Alex Bykovskyi on February 13, 2017
5/5 (3)

Introduction

In this article, we are going to continue testing Synology DS916+ with StarWind Virtual SAN. Our main goal today is to improve the performance of Synology boxes specifically on random patterns. Randoms were chosen for a reason. SQL and OLTP workloads tend to cause huge stress, especially, to spindle arrays, generating a heavily randomized I/O. Patterns we are choosing for today’s benchmark are common for such environments. There are different approaches, which can handle these workload types, such as caching and tiering. Our approach is to build environment with StarWind Log-Structured File System. LSFS was created exactly for this type of environments to improve the performance.

We will compare the results we receive to the ones from Part 1 of our research.
