Smart Array 642 RAID 验证兼容:

Smart Array 642 Controller (SA-642) is a 64-bit, 133-MHz PCI-X, dual channel, SCSI array controller for entry-level hardware-based fault tolerance. Utilizing both SCSI channels of the SA-642 allows you to configure up to 6 internal and 14 external hard drives to store up to 6 TB of storage. SA-642 also features complete data compatibility with previous generation's Smart Array controllers to ease data migration from server to server and for easy controller upgradeability

• Compatibility with all Ultra320, Ultra3 and Ultra2 LVD family products. In addition, a seamless upgrade to next generation HP high performance and high capacity mainstream Ultra320 Smart Array controllers.
• Recovery ROM protects against a ROM corruption.
• Ultra320 SCSI technology delivers high performance and data bandwidth up to 320-MB/s bandwidth per channel.
• Modular, easy-to-upgrade design lets you optimize performance as needed with the 64MB and 128MB BBWC Enabler, from 64-MB of memory for RAID and read cache to up to 128-MB of BBWC.
• Mix-and-match LVD SCSI compatibility protects your investments and lets you deploy drives as needed.
• 64-bit, 133-MHz PCI-X interface boosts bandwidth above 1B/s burst transfer rate over PCI-X bus.
• 64-bit memory addressing supports servers with greater than 4 GB of memory.
• 64-MB memory optimizes performance and data throughput.
