Overview

The Dell™ PowerEdge™ Expandable RAID Controller (PERC) 6 family of
controllers and the Dell Cost-Effective RAID Controller (CERC) 6/i offer
redundant array of independent disks (RAID) control capabilities. The PERC 6
and CERC 6/i Serial Attached SCSI (SAS) RAID controllers only support
Dell-qualified SAS and SATA hard disk drives (HDD) and solid-state
drives (SSD). The controllers are designed to provide reliability, high
performance, and fault-tolerant disk subsystem management.

PERC 6 and CERC 6/i Controller Descriptions

The following list describes each type of controller:
The PERC 6/E Adapter with two external x4 SAS ports and a transportable
battery backup unit (TBBU)
The PERC 6/i Adapter with two internal x4 SAS ports, with or without a
battery backup unit, depending on the system
The PERC 6/i Integrated controller with two internal x4 SAS ports and a
battery backup unit
The CERC 6/i Integrated controller with one internal x4 SAS port and no
battery backup unit
Each controller supports up to 64 virtual disks.
NOTE:
The number of virtual disks supported by the PERC 6/i and the CERC 6/i
cards is limited by the configuration supported by the system.

PCI Architecture

PERC 6 controllers support a Peripheral Component Interconnect
Express (PCI-E) x8 host interface.
CERC 6/i Modular controllers support a PCI-E x4 host interface.
NOTE:
PCI-E is a high-performance input/output (I/O) bus architecture designed to
increase data transfers without slowing down the Central Processing Unit (CPU).
