![]() If you change the model of disk, your raw numbers will change accordingly-but for the most part, their relation to a single disk's performance will not. All of our charts relate the performance of ZFS pool topologies at sizes from two to eight disks to the performance of a single disk. If you aren't yet entirely solid on the difference between pools and vdevs or what ashift and recordsize mean, we strongly recommend you revisit those explainers before diving into testing and results.Īnd although everybody loves to see raw numbers, we urge an additional focus on how these figures relate to one another. We're going to draw heavily on lessons learned as we explore ZFS topologies here. But at some point, people (particularly computer enthusiasts on the Internet) want numbers.įirst, a quick note: This testing, naturally, builds on those fundamentals. ![]() It's also important to understand what ZFS is and how it works. To truly understand the fundamentals of computer storage, it's important to explore the impact of various conventional RAID (Redundant Array of Inexpensive Disks) topologies on performance. This has been a long while in the making-it's test results time. Understanding RAID: How performance scales from one disk to eight.ZFS 101-Understanding ZFS storage and performance. ![]()
