LSI 9300-4i

CONDITION:NEW

Overview The LSI PCI Express(PCIe® )-to-Serial Attached SCSI (SAS) host bus adapter (HBA), referred to as the LSI 12Gb/s SAS HBA, provides high-performance internal storage connectivity for servers and workstations. The LSI 12Gb/s SAS HBA provides four lanes of 12Gb/s SAS connectivity and is matched with eight lanes of PCIe 3.0 8Gb/s performance. The low-profile design of the SAS HBA includes a full-height bracket and low-profile mounting bracket that create a universal fit for any server. The LSI 12Gb/s SAS HBA is based on the Fusion-MPT™-architected LSI SAS 3004 controller that integrates the latest enhancements in PCIe 3.0 technology and 12Gb/s SAS technology. The LSI 12Gb/s SAS HBA has onboard Flash memory for the firmware. 2 Features This section lists the LSI 12Gb/s SAS HBA features.  Implements one LSI SAS 3004 four-port 12Gb/s SAS to PCIe 3.0 controller  Supports eight-lane, full-duplex PCIe 3.0 performance  Supports SATA link rates of 3Gb/s and 6Gb/s  Supports SAS link rates of 3Gb/s, 6Gb/s, and 12Gb/s  Provides one x4 internal mini-SAS HD connector (SFF-8643)  Supports passive copper cable, active copper cable, and optical cable  Can upgrade to support Integrated RAID (RAID 0, RAID 1, RAID 10, and RAID 1E)  Supports up to 1024 SATA or SAS end devices  Offered with a full-height bracket and a low-profile vented bracket  Provides one heartbeat LED 3 Functional Descriptions 3.1 PCI Express Interface PCIe is a high-speed standard local bus for point-to-point interfacing of I/O components to the processor and the memory subsystems in high-end computers and servers. The LSI SAS 3004 controller chip contains the PCIe functionality for the LSI 12Gb/s SAS HBA. The LSI SAS 3004 controller chip connects to the PCIe bus and generates timing and protocol in compliance with the PCIe specifications. The LSI 12Gb/s SAS HBA supports eight-lane PCIe performance up to 64Gb/s single direction

SAS-3 Interface The LSI SAS 3004 controller chip contains the SATA+SAS functionality for the LSI 12Gb/s SAS HBA. The following table shows the LSI SAS 12Gb/s SAS performance. 3.3 LED Management The LSI 12Gb/s SAS HBA offers LED management support for your backplane implementation. This configuration option lets you use the LSI 12Gb/s SAS HBA with backplanes configured for the SGPIO interface. The LSI 12Gb/s SAS HBA is in accordance with SFF-8485: Specification for Serial GPIO (SGPIO) Bus, Revision 0.7

LSI SAS 9300-4i HBA Characteristics 5.1 Memory The LSI 12Gb/s SAS HBA provides one 4-M × 16-bit Flash ROM to store the firmware and the BIOS. The LSI 12Gb/s SAS HBA can provide up to 32 K × 8-bit NVSRAM for storing nonvolatile RAID information when a system failure occurs or to reflash the board to run IR firmware. 5.2 LED The LSI 12Gb/s SAS HBA Heartbeat LED, CR1, blinks green to indicate the HBA is capable of general activity.
