Data Integrity

14
The highest levels of data integrity are provided by HP disk arrays. This is
accomplished by using RAID technologies, along with redundant hardware
throughout your disk array. Refer to the Appendix for more information
about RAID technology. Below is a list of the hardware features that allow
the XP512 and XP48 to achieve their high availability and data integrity:
• RAID0/1, RAID5
• mirrored write cache
• dual channel adapters (CHAs) and array control processors (ACPs)
• dual and concurrently active data and control paths through the disk
array
• split power domains on internal data paths
• hot-pluggable boards
• hot-pluggable fans, power supplies, and controllers
• upgradable online firmware
Following are some of the software features/products that complement your
disk array hardware to ensure that the array meets your requirements for
high reliability:
• HP SureStore E support
"Phone Home" capability to multidisciplinary "Stress-Free" Center
advanced remote diagnostics
full-solution (Host-SAN-Storage) support
