Three years ago, the Lenovo ThinkSystem SR635 was introduced into our StorageReview testing lab as a high-performing, feature-rich server equipped to handle a wide variety of tasks. With a robust build and packed specifications, the SR635 had an immediate impact, quickly becoming one of the cornerstones of our testing environment. We recently decided to revisit this reliable machine many years on to look at how it has held up as a mainstay of our lab over that time.
