About Your New SmartRAID V Controller

Introduction

DPT SmartRAID V products incorporate the latest intelligent controller

technology to deliver optimum performance for desktop systems, file

servers or multi-user host systems.

NOTE ECC-protected cache is available when you use DPT SM4050 or

DM4050/DM4060 memory modules.

PM3755U2 controllers require DPT DM4050 or DM4060 memory

modules. Non-DPT DIMM modules are not supported.

€ Millennium controllers support RAID 0, 1, 5 and multilevel RAID

(0+1 and 0+5). Millennium controllers support a maximum of 256MB

of onboard cache.

• Century controllers support RAID 0 and RAID 1. You can upgrade to

hardware RAID 5 support and up to 64MB of onboard cache by adding

an RA4050 RAID Accelerator module.

Century PM2654U2 controllers support RAID 0, RAID 1 and RAID 5

with a pre-installed RA4050 RAID Accelerator. You can have a

maximum of 64MB of cache on the RA4050 module.

• Decade controllers support RAID 0, 1 and 5 and include 4MB of

onboard cache.

You can upgrade a Decade controller by adding an RA4050 RAID

Accelerator module to support hardware XOR for RAID 5 and a

maximum of 64MB of onboard cache.

• SX405x Bus Expansion Modules add extra SCSI channels or a Fibre

Channel port to SmartRAID V controllers. You can use a Fibre

Channel expansion module to provide both SCSI and Fibre Channel

connections on a SmartRAID V SCSI controller.

• The RA4050 RAID Accelerator provides up to 64 MB of cache and

adds hardware RAID 5 capability to a Century controller or adds

hardware XOR and up to 64MB of cache to a Decade controller.

• The BB4050 Battery Module provides battery backup for the onboard

cache on a Millennium PM3755U2B controller.
