Is the server's mass storage protection integrated with its management software?
Since electromechanical devices like drives are more likely to fail than other parts of my
server, can the server management system—locally or remotely—completely view and
control the disk subsystem?
Does the vendor's storage performance meet expectations?
Do the disks provide sufficient capacity? Are the data transfer rates fast enough?
How should data and applications be organized on the server?
Are server usage patterns understood?
Are adequate backup procedures in place for important server data?
The data protection techniques described in this paper can be used to make server disk
subsystems extremely reliable, but backup is still absolutely necessary. These techniques
do not protect from accidental or malicious destruction, theft, or site-wide problems like
flood or fire.
What kind of data protection is appropriate?
Is it acceptable to rely on disk backup procedures alone, replacing drives when they fail,
temporarily interrupting users and possibly losing new data not yet backed up? Is it
acceptable to continue operating, but with degraded performance, after a failure? Or do we
require a solution that ensures uninterrupted, full-speed performance despite failures?
What is the cost of downtime?
Can the cost to the organization be expressed in financial terms like lost revenue or profit
per hour or day, allowing an intelligent decision about data protection? How closely related
is this server to revenue or profitability, or to the productivity of the employees?
