Intel SE7520JR2 manual Revision C78844-002

Intel® Server Board SE7520JR2 Functional Architecture

•Quick arbitrate and select (QAS)

•Skew compensation

•Inter-symbol interference (ISI) compensation

•Cyclic redundancy check (CRC)

•Domain validation technology

The LSI53C1030 contains the following SCSI performance features:

•Supports Ultra320 SCSI

•Paced transfers using a free running clock

•320 MB/s data transfer rate on each SCSI channel

•Mandatory packetized protocol

•Quick arbitrate and select (QAS)

•Skew compensation with bus training

•Transmitter precompensation to overcome ISI effects for SCSI data signals

•Retained training information (RTI)

•Offers a performance optimized architecture

•Three ARM966E-S processors provide high performance with low latency

•Two independent Ultra320 SCSI channels

•Designed for optimal packetized performance

•Uses proven integrated LVDlink transceivers for direct attach to either LVD or SE SCSI buses with precision-controlled slew rates

•Supports expander communication protocol (ECP)

•Uses the Fusion-MPT (Message Passing Technology) drivers to provide support for Windows*, Linux, and NetWare* operating systems

The LSI53C1039 has a 133 MHz, 64-bit PCI/PCI-X interface that supports the following PCI features:

•Operates at 33 MHz or 66 MHz PCI

•Operates at up to 133 MHz PCI-X

•Supports 32-bit or 64-bit data

•Supports 32-bit or 64-bit addressing through Dual Address Cycles (DAC)

•Provides a theoretical 1066 Mbytes/s zero wait state transfer rate

•Complies with the PCI Local Bus Specification, Revision 2.2

•Complies with the PCI-X Addendum to the PCI Local Bus Specification, Revision 1.0a

•Complies with the PCI Power Management Interface Specification, Revision 1.1

•Complies with the PC2001 System Design Guide

•Offers unmatched performance through the Fusion-MPT architecture

•Provides high throughput and low CPU utilization to off load the host processor

•Presents a single electrical load to the PCI Bus (True PCI Multifunction Device)

•Uses SCSI Interrupt Steering Logic (SISL) to provide alternate interrupt routing for RAID applications
