AOC-LPZCR2 User's Guide Chapter 1 Introduction This manual is written for system integrators, PC technicians and knowledgeable PC users who intend to integrate Supermicro's Second Generation Zero-Channel RAID solution into their RAID system. It provides detailed information for the installation and use of the AOC-LPZCR2 All-In-One card that supports SAS/ SATA/SCSI confi gurations in a slim-size card. Outperforming our fi rst generation ZCR cards, the Supermicro AOC-LPZCR2 offers an innovative, mature, complete and cost effective solution to the ever-increasing demands of disk density and data integrity of today's servers.
1.1 Overview The AOC-LPZCR2 is a highly effi cient, highly compatible and easy-to-use RAID card that allows the user to take advantage of the AMI MG9071/9072 Firmware and the Q-Logic GEM318/359 Firmware to confi gure RAID 0, RAID 1, RAID 5, RAID 10, JBOD*, and RAID50**. With Intel's 80321 600 MHz I/O Processor and 256 MB ECC DDR memory built-in, the AOC-LPZCR2 supports PCI-X speeds up to 100MHz and provides the user with a high-speed, space-saving, scalable and intelligent hardware RAID solutions. (Notes: *JBOD is available for SATA/SAS/SCSI only.
**RAID 50 is available for SAS and SATA only.) 1.2 Introduction to SATA (Serial ATA) and SAS (Serial Attached SCSI) Serial ATA(SATA) is a physical storage interface. It uses a single cable with a minimum of four wires to create a point-to-point connection between devices. It is a serial link which supports SATA transfer rates from 150MBps. Because the serial cables used in SATA are thinner than the traditional cables used in Parallel ATA (PATA), SATA systems provide more effi cient system cooling, faster data transfer and better functionality than Parallel ATA.
With the functionality provided by the onboard SAS Firmware, the AOC-LPZCR2 offers unprecedented I/O throughput, reliability and scalability to the IT industry. In addition, with a dynamic serial-link transmission infrastructure built-in, the AOC-LPZCR2 supports both SATA and SAS without any bridging, providing the user with unparalleled data storage expansion and inter-connectivity capability. 1.3.1 SCSI Enclosure Services 2 (SES-2) and SCSI Ac- cessed Fault Enclosure Management (SAF-TE) The AOC-LPZCR2 offers the following SES-2 and SAF-TE advanced features:
Supports SAF-TE Industry standard to interface with enclosed components Supports Disk Drive Failure Alarm and LED indicator Supports Disk Drive Rebuild LED Indicator Supports Disk Drive Hot Spare LED Indicator 1-4
