Choosing Your Array Type
Transaction
server
Users at multiple PCs
randomly access the server
mostly for creating new files
and for updating old ones
(for example, hospital or
banking applications),
making data availability
critical; requires high
random-read performance
and fault tolerance.
Stripe set of mirror sets
(RAID 0/1)
Stripe set of RAID 5
sets (RAID 0/5)
Alternate configuration:
Stripe set (RAID 0) to
store and manage
data; mirror set (RAID
1) to maintain a
transaction log file
Video server
Users transfer large blocks of
sequential data from the
server, edit the data, and
return the data to the server;
requires high sequential-read
and -write performance.
Stripe set (RAID 0)
Stripe set of RAID 5
sets (RAID 0/5)
RAID 5 set (if fault
tolerance is required)
Web server
Users log in to the server to
locate and view information.
Sometimes they enter data
such as registration
information or transfer data
if an FTP site allows it.
