Back in the day, RAID (Redundant Array of Independent Disks) was considered the king of the storage landscape. Businesses paid a lot to receive the much expensive privilege of data protection. In today’s world though, the once-hot breakthrough technology is considered a sin among most storage circles.

Commonly used as a secondary data protection technology, it helps increase the performance and reliability of data storage. On a physical level, it’s a logical configuration of multiple physical drives to provide fault tolerance and data optimization in a system. One can organize data in a RAID array in different levels by balancing data and recovery needs or speed and fault tolerance properties – essentially whatever factors are most critical to the business.

Storage HA on the Cheap: Fixing Synology DiskStation flaky Performance with StarWind Free. Part 2 (Log-Structured File System)

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.
