DPT PM3754U2 PCI SCSI RAID Controller SmartRAID V Ultra2 16MB Cache Card

DPT PM3754U2 PCI SCSI RAID Controller SmartRAID V Ultra2 16MB Cache Card

The DPT PM3754U2 is a full-length PCI SCSI RAID controller card from DPT's SmartRAID V Millennium series. It provides hardware RAID processing for a single Ultra2 SCSI (LVD) channel with 16MB of onboard cache memory, offloading RAID calculations from the host CPU to the card's dedicated controller. The PM3754U2 connects to SCSI hard drives via a 68-pin VHDCI external connector and internal headers, and fits into a standard PCI slot in a server or workstation motherboard.

Applications

DPT (Distributed Processing Technology) was a well-regarded U.S. manufacturer of PCI SCSI RAID controllers in the mid-to-late 1990s, and the SmartRAID V Millennium series was among the company's higher-end offerings of that period. Cards like the PM3754U2 were used in server and workstation builds running Windows NT, Windows 2000, Novell NetWare, and Linux, where hardware RAID was needed to protect data or improve disk I/O performance without loading the host CPU. Ultra2 SCSI (also called LVD SCSI) doubled the bus bandwidth of earlier Ultra SCSI to 80 MB/s and extended cable length, making it the dominant server disk interface in the late 1990s before Serial Attached SCSI (SAS) and SATA became standard. These cards remain useful in legacy server maintenance, period-correct workstation restorations, and hobbyist builds centered on late-1990s hardware.
