One of the most common performance metrics used in storage design is IOPS, but isn't iops enough to help us make design decisions? There are many misunderstandings in this area. In the vast majority of cases it is meaningless to think only of IOPS alone. This article takes you through a case study to fully consider all

operations a device can perform.With the increased ability to include storage devices within the server, especially with PCIe memory cards, the IOPS capacity is typically 10 tens of thousands of, which is immediately superfluous. In this case, a server can do a lot of things and run a lot of services on it. So how to ensure the service quality of the system is a very important thing.We tend to use cgroup t

Dual-machine hot with two implementation modes, one is based on shared storage devices, the other is not shared storage devices, generally referred to as a pure software approach. Dual-Machine hot standby based on storage sharing is the most standard scheme for dual-machine hot standby. For this approach, two servers

This article mainly introduces the functions of pure js to implement local storage with an infinite space size. the source code and demo are all provided to you. This article focuses on the implementation principles. the specific practices can be freely used by our partners. I haven't written a blog for a long time. I thought that I didn't release the source code that I promised two years ago. Recently, I a

This is a creation in Article, where the information may have evolved or changed. Blot Bolt is a pure Go Key/value database inspired by Howard Chu's LMDB project. The goal of this project is to provide a simple, fast and reliable database for projects that do not require a full database server (such as Postgres or MySQL). Since Bolt is used as such a low-level function, simplicity is key. The API will be small, focusing only on getting values and sett
