HP Smart Array 431 Single Channel PCI 64-bit Ultra3 SCSI RAID Controller

SKU CH-6AQ6-SYXFB

Adds single-channel Ultra3 SCSI RAID to 64-bit PCI servers

  • Single-channel RAID controller simplifies storage management
  • 64-bit PCI interface supports high-throughput data transfer
  • Ultra3 SCSI connectivity enables fast peripheral communication
  • Compact 8.5 x 18.5 form factor fits dense server chassis

HP Smart Array 431 RAID Controller

This HP Smart Array 431 is a single-channel PCI RAID controller designed for servers that use Ultra3 SCSI storage. It fits into a 64-bit PCI slot and manages RAID arrays for compatible Compaq and HP ProLiant systems. Buyers who need multiple channels or a newer PCI Express interface should look elsewhere.

64-bit PCI bus limits

The card operates on a 64-bit PCI bus, so throughput is capped by that bus standard rather than the SCSI interface alone. Systems lacking a 64-bit PCI slot cannot use the controller at its intended width. No onboard cache or battery-backed write cache is included with this card.
