.Nd DPT RAID Controller SCSI driver
|
|
.Sh SYNOPSIS
|
|
For one or more EISA Controllers
|
|
.Cd "device eisa"
|
|
.Cd "device dpt"
|
|
.Pp
|
|
For one or more PCI Controllers
|
|
.Cd "device pci"
|

.Cd "device dpt"
|
|
.Pp
|
|
To allow PCI adapters to use memory mapped I/O if enabled:
|
|
.Cd options DPT_ALLOW_MEMIO
|
|
.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:
