Flexible caching policies in PERC 6 RAID controllers allow administrators to tune cache writing schemes to help optimize performance or maximize data protection, including choosing between write-through caching and write-back caching.
PERC 6 controllers include features that can automatically track disk order and organization through disk roaming.
PERC 6 controllers also support moving physical disks from one cable connection or backplane slot to another on the same controller; the controllers can automatically recognize the relocated physical disks and logically place them in the appropriate virtual disks that are part of the disk group.
The Advanced Import feature enables administrators to import, or migrate, disk arrays created by a different PERC controller while the server remains online. The controllers can even import partial, or degraded, arrays and provide array preview capabilities before import to further enhance data serviceability.
PERC 6 controllers utilize Smart Cache Technology that offers administrators pre-tuned cache ratios for read and write operations that automate cache allocations based on the characteristics of the storage environment.
Administrators can also perform realtime RAID-level migration by converting one RAID level to a different RAID level.
