PERC 5/E and PERC 6/E are the RAID controllers used to connect the PowerVault MD1xxx
Family storage enclosures to one or two PowerEdge servers. They support 3 Gbps Serial Attached
SCSI (SAS) as the storage interconnect technology and PCI Express (PCI-E) as the host-based
interconnect technology. The "E" in PERC 5/E and PERC 6/E stands for "External" because the
PERC controllers supports only physical disks that attach to a server externally.
The PERC 5/E controller offers:
•
Intel IOP333 I/O processor based on Intel XScale Microarchitecture
•
256MB of customized DDR2 400MHz, Error-Correcting Code (ECC) cache memory
•
3 Gbps maximum speed for each SAS lane
•
Two external x4 (by four) SAS ports, each aggregating 4 SAS lanes for a total bandwidth per
port of 12.0 Gbps
•
x8 PCI E host interface for a total bandwidth of 32.0 Gbps
•
Up to 72 hours of intelligent, transportable, battery-backed, cache memory
The PERC 6/E controller offers:
