Understanding the Array Selection Criteria
Comparing the Selection Criteria
Determining which array type to use depends on the applications
running on your server and trade-offs between performance and
cost.
Before you choose your array type in Storage Manager Pro, you
should evaluate your needs based on the following:
Performance-This is based on the requirements of the
I
applications to be run on the system you are setting up. Key
performance issues to consider include:
- Fault tolerance-Ability of the system to recover from a failure
of one of more drives without interrupting user or application
access to data.
- Load balancing-Ability to spread I/O across drives.
- Write performance-Ability to write large amounts of data
quickly.
