- DPT RAID Controller SCSI driver
To compile this driver into the kernel,
place the following lines in your
kernel configuration file:
.Cd device scbus
.Cd device dpt
For one or more EISA cards:
.Cd device eisa
For one or more ISA cards:
.Cd device isa
For one or more PCI cards:
.Cd device pci
To allow PCI adapters to use memory mapped I/O if enabled:
.Cd options DPT_ALLOW_MEMIO
Alternatively, to load the driver as a
module at boot time, place the following line in
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
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
