Today we continue discussing the best practice from storage engineering:

460) The use of injectors, proxies, man-in-the-middle test networking aspect but storage is more concerned with temporary and permanent outages, specific numbers associated with minimum and maximum limits and inefficiencies when the limits are exceeded.

461) Most storage products have a networking aspect. Testing covers networking separately from the others. This means timeouts, downtime, resolutions and traversals up and down the networking layers on a host. It also includes location information.

462) The control and data path traces and execution cycles statistics are critical to capture and query with a tool so that the testing can determine if the compute is at fault. Most such tools provide data over the http.

463) Responsiveness and accuracy are verified not only with repetitions but also from validating against different sources of truth. The same is true for logs and read-only data

464) When data is abundant, reporting improves the interpretations. Most reports are well-structured beforehand and even used with templates for different representations.

465) Testing provides the added advantage of sending reports by mail for scheduled runs. These help human review of the bar for quality
