The file system on Linux is generally EXT2 or EXT3, but this article is not ready to talk about them directly, but I want to combine the Linux operating system and from the foundation of the file system-the hard disk to start, step-by-step understanding of the Linux file system. 1. Physical storage mechanism of mechanical hard disk Most of the file storage functions of modern computers are provided by such devices as mechanical hard drives. (now the

It is well known that after the upgrade of SSD, the speed and performance of the computer have been greatly improved. However, some users upgrade SSD, speed and performance improvement is not obvious. The reason is that the SSD is not properly used and the operating system is installed. The common problem is that the 4K is not aligned, does not turn on the trim,

Q: Vsan needs to use SSD, what's the use of it? A: SSD is used for read caching (70%) and write Buffering (30%). Each write will go to SSDs first, and then cancel the staging to the HDD later. Q: When you create a VSAN virtual machine storage Policy, when should you use the "allowed number of failures", when should use "stripe width". A: The number of allowed failures is related to availability, and you c
