When platforms are built on RAID arrays, rebuild times can come into play after a drive failure or replacement. Downtime can result in lost productivity and—even worse—lost revenue. As a result, rebuild times can be critically important to organizations that are weighing the pros and cons of an upgrade. To determine if the newer system offered an advantage in this area, Prowess compared rebuild times for the same two systems. To perform this testing, engineers removed one of the drives from the data array, and then recorded the time required to rebuild the system and resume SQL Server production use. We performed this process twice, and then repeated for the second log file array. Figure 2 shows the median of the two runs for each array, comparing the older generation platform to the newer one.
