How To Set Up an NFS Server Using Block Storage

NFS, or Network File System, is a distributed file system protocol that allows you to mount remote directories on your server. *Block storage* is a generic term used to describe network-based storage volumes that are usually offered by hosting providers. Block storage usually does not provide its own API for direct access. Instead, it needs to be mounted to an existing server and shared from that server. Running an NFS server on an attached droplet is a good solution to expose block storage.

How To Configure Periodic TRIM for SSD Storage on Linux Servers — step-by-step Linux tutorial on Progressive Robot

How To Configure Periodic TRIM for SSD Storage on Linux Servers

Continuous use of SSDs results in degraded performance if not accounted for and mitigated. The TRIM command is an operation that allows the operating system to propagate information down to the SSD about which blocks of data are no longer in use. This allows the SSD’s internal systems to better manage wear leveling and prepare the device for future writes. Continuous TRIM is possible, but can negatively impact performance. Scheduled, periodic TRIM is a good alternative in most cases.
