HP offers a disk array with a patented technology named AutoRAID. AutoRAID
hardware and software monitor the use of data on a system to provide
the best possible performance by determining the best RAID array
level for that specific system.
With a traditional array, the process of configuring the system
for optimum performance is time-consuming and error prone. You must perform
numerous tasks and then choose between RAID 1 and RAID 5, considering
the advantages and trade-offs of each. You must then do performance
tuning and evaluate the impacts across the entire systems environment.
The entire process can take anywhere from a few hours to days and
even weeks.
With AutoRAID, the data is managed for you so that you do
not have to do this kind of extensive configuration. The entire
configuration process can be completed within less than a minute
and once the array is up and running, it continuously and automatically
optimizes its own performance. It chooses the appropriate RAID level
for you, either RAID 1 or RAID 5, to provide the best performance
characteristics, depending upon the changing application workloads.
AutoRAID allows data from different arrays to be managed as
a single array. The data within a given array may be a mixture of
RAID 1 and RAID 5.
Pros and
Cons of AutoRAID |
 |
An HP disk array with AutoRAID provides improved performance
over traditional RAID systems. It adapts to the system workload
by dynamically moving data between multiple arrays with different
RAID levels, or within a single array.

Uses of AutoRAID |
|
Cost and capacity make AutoRAID a good choice in many situations where
50 to 200 GB of storage are required and where you would like the system
software to help tune the system for best disk array performance.
