Compaq HSG80 Array Controller ACS Version 8.4 Configuration and CLI Reference Guide
For example, if the mean time between failures (MTBF) for a single disk is one
hour, then the MTBF for a stripeset that comprises N such disks is l/N hours. As
another example, if a single disk’s MTBF is 150,000 hours (about 17 years), a
stripeset comprising four of these disks would only have an MTBF of slightly
more than four years.
For this reason, you should avoid using a stripeset to store critical data. Stripesets
are more suitable for storing data that can be reproduced easily or whose loss
does not prevent the system from supporting its critical mission.
â– Evenly distribute the members across the device ports to balance load and
provide multiple paths as shown in Figure 4–4.
