BCM5770/BCM5770R Applications
BCM5770/BCM5770R highly integrated, multiport SATA-I controller that been designed high performance storage applications requiring host utilization maximum performance. device communicates with host 64-bit, 133-MHz PCI-X1.0 interface. attaches directly maximum eight SATA-I disk drives backplanes target side high-performance, integrated SATA that capable driving long-length backplanes. Additionally, BCM5770/BCM5770R supports hot-plug capability, enabling SATA disk drives inserted removed from storage rack server without affecting system operation. high-bandwidth host arbiter GB/s) decouples PCI-X host interface from SATA ports, enabling maximum throughput workloads demanding sequential performance. Data from/to drives broken into 8-KB data FISes SATA links. PCIX interface arbitrated based round robin algorithm. Data transferred 512-byte blocks PCIX, thereby allowing fairness among data channels. BCM5770/BCM5770R provides interrupt coalescing mechanism pace host interrupts generates. This allows host software
batch-process interrupts efficiently. addition, BCM5770/ BCM5770R incorporates mechanism reduce reads periodically DMAing BCM5770/BCM5770R status block into host memory. Both these mechanisms vastly reduce host utilization limiting amount adaptor accesses that must performed. Count (LPC) Interface Specification compliant interface available connect BCM5770/BCM5770R external flash/ Three general-purpose pins with tri-state capability available specially configured drive LEDs. master interface also available communicate with external enclosure management device with serial EEPROM. On-board power supply regulators available that generate local 2.5V 1.2V rails, allowing entire chip from single external 3.3V power source. Built-in PRBS pseudo-random sequence test generators/checkers available port testing without additional hardware drives. These programmed from in-band interface.
