Noop I/O scheduling with SSD storage

By | Technical | No Comments

Solid State Drives (SSDs) are not new in the server world, but they’re seen a somewhat limited takeup due to their high cost per gigabyte of storage. This has been changing as prices continue to drop, and we’re now at the point where SSDs represent a viable option for primary storage of high-value data that is read and written heavily. While SSDs are a drop-in replacement for traditional hard drives (HDDs) when it comes to servers, their behaviour and performance characteristics are fundamentally different. This means that the disk-access scheduling algorithms that we’ve developed over time, originally designed for rotational media, simply don’t work for SSDs. We recently observed some interesting behaviour as a result of changing disk access schedulers, which we thought we’d share with you here. The difference…

To protect your data…
