storage spaces. And that's it, the space is available. You don't have to repartition anything. You don't have to resize any volumes. You don't have to back up any data and restore it. It makes things a lot easier. Data Resiliency 3:26-6:12 Another key benefit is that Storage Spaces include a degree of data resiliency. We have several different options for how that data resiliency is going to work, and you can see that in the screenshot over here. Notice that the first option is called simple, which as its name implies really doesn't have any resiliency. In this situation, you would create a simple storage space by simply allocating space from a storage pool to the storage space, and there's no redundancy involved. This is dangerous because if one of your hard disk drives were to fail, then you would lose all of the data on the entire storage space. To prevent this, Storage Spaces offers several resiliency options to make your files redundantso that if a disk fails, you won't lose any data. And you can see those here. We have a two-way mirror, three-way mirror, and parity. Be aware that using one of these resiliency options will require you to allocate some space for the redundant information. In other words, it'll reduce the amount of space available for just data storage, but it's worth it because your data is much safer. Let's take a look at what each of these three data resiliency options offer, beginning with two-way mirroring.

Two-way mirroring requires at least two physical disks because two-way mirroring places a copy of the data saved in the storage space on both drives so that if one of the drives dies, the other one can still provide the data that was stored on the other one. Another option is three-way mirroring. Three-way mirroring is much more complex than two-way mirroring. Three-way mirroring requires at least five hard disk drives. Three-way mirroring will store a copy of each file stored in the storage space on three of the five hard disk drives. This give you a lot less usable space than two-way mirroring does, but it provides more safety because it can toleratethe failure of up to two disks at the same time. So with two-way mirroring, we can tolerate one disk failing. With three-way mirroring, we can tolerate up to two disks failing at the same time. The third option for data resiliency in a storage space is parity. Parity is similar in a lot of ways to Raid 5. Parity requires that you have at least three hard disk drives, and as its name implies, it used parity information so that if one of the disks fails the data can be reconstructed using the parity information. This has a couple of advantages. The key among these is the fact that it uses less physical space on each disk, providing you with more storage space for your actual data, but that comes at a cost in terms of performance overhead, meaning that it's not going to perform as fast as one of your other mirroring options.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
