SYNOPSIS

For one or more EISA Controllers
.Cd "device eisa"
.Cd "device dpt"

For one or more PCI Controllers
.Cd "device pci"
.Cd "device dpt"

To allow PCI adapters to use memory mapped I/O if enabled:
.Cd options DPT_ALLOW_MEMIO

DESCRIPTION

The dpt driver supports DPT RAID SCSI controllers.

SmartRAID (PM3???) are "Enterprise" class cards, and SmartCache (PM2???) cards are in the "Workstation" class. The Gen 4 Smart Cache IV products were a re-issue of the Gen 3 utilizing upgraded (and cheaper to produce) silicon. The PM3334 (Smart RAID III) was not revamped as there was no upgraded silicon (68040 processor) and it was using the best DPT made. Note there has been customer confusion over the faster enterprise class card supported by this driver being an older generation. The Gen5 cards are supported by the asr(4) driver.

HARDWARE

The dpt driver provides support for the following RAID adapters:

  • DPT Smart Cache Plus
  • Smart Cache II (PM2?2?, PM2022 [EISA], PM2024/PM2124 [PCI]) (Gen2)
  • Smart RAID II (PM3?2?, PM3021, PM3222)
  • Smart Cache III (PM2?3?)
  • Smart RAID III (PM3?3?, PM3332 [EISA], PM3334UW [PCI]) (Gen3)
  • Smart Cache IV (PM2?4?, PM2042 [EISA], PM2044/PM2144 [PCI]) (Gen4)
  • Smart RAID IV
