Detailed Description

Enterprise RAID-on-Chip controller from the LSI SAS1078 family

Supports SAS and SATA drives for 3 Gb/s enterprise storage

Ideal for hardware RAID acceleration on server and storage adapter cards

Main category Integrated Circuits ICs

Small classification Specialized ICs

Package BGA, case code 869

Typical use in RAID controller cards and embedded server RAID

Current stock available 4780 units for fast fulfillment

Key Features

SAS and SATA connectivity at 3 Gb/s per lane

Up to 8 SAS lanes depending on board design and configuration

PCI Express host interface for high bandwidth connection to the system

Hardware RAID engine with acceleration for parity and mirroring

Supports common RAID levels such as 0, 1, 5, 6, 10, 50, 60 depending on firmware

Interoperable with expanders to scale drive count

Works with enterprise SAS, SATA, and nearline SAS HDDs and SSDs

Robust management and error handling features for enterprise reliability

Key Advantages

Offloads RAID processing from the host CPU for faster, more consistent I/O

Proven ecosystem with wide OS and platform support

Stable performance for legacy 3 Gb/s SAS and SATA infrastructures

Broad interoperability with drives, backplanes, and expanders

Scales from small servers to larger arrays using expanders

Immediate availability from Y-IC helps reduce supply risk

Packaging

Type BGA, case code 869

Material Lead-free, RoHS compliant molding compound and substrate per LSI manufacturing standards

Size High ball count BGA footprint suitable for enterprise controller boards Refer to the datasheet mechanical drawing for exact dimensions

Pin configuration Ball grid array with defined ball map and signal groups High speed SERDES for SAS and PCIe requires controlled impedance routing Follow reference design guidelines

Thermal Requires proper heatsink and airflow for reliable operation Use suitable thermal interface material Observe junction temperature limits and thermal derating in the datasheet

Electrical Multiple power rails for core, SERDES, and I O PCIe Gen1 signaling and SAS 3 Gb s PHYs require clean power and decoupling Follow power sequencing, filtering, and layout rules in the datasheet

Lifecycle

Status Legacy product widely deployed in the field Many variants are NRND or EOL in new designs

Recommendation For new designs, move to newer LSI Broadcom ROC families with 6 Gb s or 12 Gb s capability

Equivalent or alternative models

- LSI SAS2108 ROC 6 Gb s next generation replacement path for SAS1078

- LSI SAS2208 ROC 6 Gb s higher performance dual core ROC

- LSI SAS3108 ROC 12 Gb s modern enterprise ROC

- LSI SAS2008 or SAS2308 I O controllers for HBA mode without hardware RAID

- LSI SAS1068E for basic 3 Gb s HBA use cases
