Support For PERC 9 and PERC 10 Hardware
Controllers
The PowerEdge RAID Controller (PERC) family of enterprise-class controllers is designed for enhanced performance, increased
reliability and fault tolerance, and simplied management — providing a powerful, easy-to-manage way to create a robust
infrastructure and help maximize server uptime. The introduction of the PERC 9 and PERC 10 family of hardware controllers also
brings about improvements in storage solutions.
The new PERC 9 and PERC 10 family of hardware controllers support the following storage enhancements:
• Support For RAID Level 10 Virtual Disk On PERC 9 and PERC 10 Hardware Controller
• Support For Advanced Format 4KB Sector Hard-Disk Drives
NOTE: The order of the controllers displayed on Storage Management may dier with the order of the controllers
displayed in the Human Interface (HII) and PERC Option ROM. The order of the controllers does not cause any
limitation.
Support For RAID Level 10 Virtual Disk Creation On PERC 9 and PERC
10 Hardware Controllers
RAID Level 10 is a solution for users who require high performance and redundancy with quickest recovery during drive failure.
Though a RAID Level 10 setup is more expensive to maintain, it has several benets as it combines the properties of RAID Level 1 and
RAID Level 0.
RAID Level 10 virtual disk creations with PERC 9 and PERC 10 hardware controllers support Uneven Span feature. When you create
RAID Level 10 virtual disks with PERC 9 and PERC 10 hardware controllers the rmware suggests the preferred span layout for the
setup.
NOTE: A minimum of 4 physical disks and a maximum of 256 physical disks are allowed for a RAID Level 10 virtual disk
setup with PERC 9 and PERC 10 hardware controllers.
You can create RAID Level 10 Virtual Disk on PERC 9 and PERC 10 hardware controllers using the following Wizards:
• Express Wizard
• Advanced Wizard
NOTE: The procedure for creating virtual disks on PERC 9 hardware controllers is the same as other PERC hardware
controllers.

RAID Level 10 Virtual Disk Creation With Uneven Span
RAID Level 10 virtual disk creation with uneven span feature is available on Storage Management User Interface (UI) and Command
Line Interface (CLI). For information on Storage Management CLI, see Server Administrator Command Line Interface Guide.
• Based on the minimum (and even) number of physical disks selection the rmware on the PERC 9 hardware controller
recommends the preferred span layout.
