- .Sh NAME
- .Nm dpt
- .Nd DPT RAID Controller SCSI driver
- .Sh SYNOPSIS
- To compile this driver into the kernel,
- place the following lines in your
- kernel configuration file:
- .Bd -ragged -offset indent
- .Cd "device scbus"
- .Cd "device dpt"
- .Pp
- For one or more EISA cards:
- .Cd "device eisa"
- .Pp
- For one or more ISA cards:
- .Cd "device isa"
- .Pp
- For one or more PCI cards:
- .Cd "device pci"
- .Pp
- To allow PCI adapters to use memory mapped I/O if enabled:
- .Cd options DPT_ALLOW_MEMIO
- .Ed
- .Pp
- Alternatively, to load the driver as a
- module at boot time, place the following line in
- .Xr loader.conf 5 :
- .Bd -literal -offset indent
- dpt_load="YES"
- .Ed
- .Sh DESCRIPTION
- The
- .Nm
- driver supports DPT RAID SCSI controllers.
- .Pp
- 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
- .Xr asr 4
- driver.
- .Sh HARDWARE
- The
- .Nm
- driver provides support for the following RAID adapters:
- .Pp
- .Bl -bullet -compact
- .It
- DPT Smart Cache Plus
- .It
- Smart Cache II (PM2?2?, PM2022 [EISA], PM2024/PM2124 [PCI]) (Gen2)
- .It
- Smart RAID II (PM3?2?, PM3021, PM3222)
- .It
- Smart Cache III (PM2?3?)
- .It
- Smart RAID III (PM3?3?, PM3332 [EISA], PM3334UW [PCI]) (Gen3)
- .It
- Smart Cache IV (PM2?4?, PM2042 [EISA], PM2044/PM2144 [PCI]) (Gen4)
- .It
- Smart RAID IV
