SSD Drive Manufacturers can come up against unexpected problems when faced with the various methods of clocking that are encountered within a test environment. For example, as PCI Express (PCIe) has evolved, the speed of the clock (and therefore the data rate and bandwidth of the bus) has increased six-fold from Gen1 to Gen4. Further, the methods of clocking that may be encountered can vary substantially, making testing very challenging.
The easiest and simplest solution to this common problem is to use the SANBlaze SBExpress-RM4 (Gen4) test platform that has clocking tests built right into the system, allowing SSD manufacturers to not only save time and cost, but ensure their drives are compliant.
This white paper explains the clocking modes required for modern NVMe devices and how to verify that your NVMe device can run correctly with each of the possible clocking schemes.
Feature Validation Using NVMe Compare
Whether you want to perform complex testing or testing that requires minimal tweaking of parameters and options, it is beneficial to learn and know what is "under the hood" when using SANBlaze. Knowing what goes on behind the scenes of SANBlaze's automated and simplified scripting can help you realize the full potential of your testing and possibly save you many "qual" hours in the process.
This white paper takes you through a SANBlaze validation process using NVM Compare as an example. You can then use any other SANBlaze command in the same way to perform testing.
