NAME¶
dpt
—
DPT RAID Controller SCSI driver
SYNOPSIS¶
To compile this driver into the kernel, place the following lines in your kernel configuration file:device scbus
device dpt
For one or more EISA cards:
device eisa
For one or more ISA cards:
device isa
For one or more PCI cards:
device pci
To allow PCI adapters to use memory mapped I/O if enabled:
options DPT_ALLOW_MEMIO
dpt_load="YES"
DESCRIPTION¶
Thedpt
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¶
Thedpt
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
