High read request rates
Inquiry-type transaction processing
RAIDsets are not particularly well-suited for the following:
Write-intensive applications
Applications that require high data transfer capacity
High-speed data collection
Database applications in which fields are continually updated
Transaction processing
Using Striped Mirrorsets for Highest Performance and Availability
As illustrated in Figure 3–8, striped mirrorsets are simply stripesets
whose members are mirrorsets. Consequently, this kind of storageset
combines the performance of striping with the reliability of mirroring.
The result is a storageset with very high I/O performance and high data
availability.
Figure 3–8 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
