Two disk schemes
Basic disks | Dynamic disks
26
RAID 0
Strictly striping disk. No spanning. | "Fast with no insurance"
27
RAID 5
Striping with parity | At least 3 disks
28
RAID 1
Mirroring.
29
Storage Pools
The collection of hardware that creates the virtual drive (the "storage space")
30
Thin Provisioning
"Just in time" provisioning, giving users space that doesn't actually exist. Will appear as 100GB when it's only 75GB
31
LUN
Logical Unit Number
32
Storage Space's main feature
You can create your own SAN using a storage pool made up of JBODs. Can mix SSD and traditional disks.
33
JBODs
Just a Bunch of Disks
34
Thin versus Fixed provisioning
Thin = Just in time. Can define your disk larger than the actual physical capacity of the LUN. Also, space is used as needed. Can be expanded by adding disks to your pool. Fixed provisioning -- your entire space is used. Cannot be expanded.
35
ReFS
