Choosing Your Array Type
In This Chapter
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
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.
