Appendix D. Solid State Drives (SSDs)

If you are planning on using Solid State Drives (SSDs) for your Oracle NoSQL Database deployment, a special consideration should be taken. Because of how SSDs work, I/O latency can become an issue with SSDs over time. Correct configuration and use of trim can help minimize these latency issues.

Trim requirements

In general, for TRIM to be effective, the following requirements must be met:

  • The SSD itself must support trim.

  • Linux-kernel 2.6.33 or later.

  • Filesystem ext4 (ext3 does not support trim).
