VTrak M310p, M210p Product Manual

There are several issues to consider when choosing the RAID Level for your VTrak disk array. The following discussion summarizes some advantages, disadvantages, and applications for each choice.

RAID 0

	Advantages	Disadvantages

	Implements a striped disk array, the	Not a true RAID because it is not fault-
	data is broken down into blocks and	tolerant
	each block is written to a separate disk	The failure of just one drive will result in
	drive	all data in an disk array being lost
	I/O performance is greatly improved by	all data in an disk array being lost
	I/O performance is greatly improved by	Should not be used in mission critical
	spreading the I/O load across many	environments
	channels and drives	environments
	channels and drives
	No parity calculation overhead is

Recommended Applications for RAID 0:

•Image Editing

•Pre-Press Applications

•Any application requiring high bandwidth

RAID 1

Advantages	Disadvantages

Simplest RAID storage subsystem	Very high disk overhead - uses only
design	50% of total capacity
Can increase read performance by
processing data requests in parallel
since the same data resides on two
different drives

Recommended Applications for RAID 1:

•Accounting

•Payroll

•Financial

•Any application requiring very high availability
