4–20 Planning Storagesets
Figure 4–8. Striping and Mirroring in the Same Storageset
The failure of a single disk drive has no effect on this storageset’s ability to deliver
data to the host and, under normal circumstances, it has very little effect on
performance. Because striped mirrorsets do not require any more disk drives than
mirrorsets, this storageset is an excellent choice for data that warrants mirroring.
Considerations for Planning a Striped Mirrorset
Plan the mirrorset members, then plan the stripeset that will contain them. Review the
recommendations in “Considerations for Planning a Stripeset,” page 4–10, and
“Considerations for Planning a Mirrorset,” page 4–14.
There are the following limitations for a striped mirrorset:
■ A maximum of 24 mirrorsets in a stripeset.
■ A maximum of 6 disks in each mirrorset.
■ A maximum of 48 disks in the entire striped mirrorset.
