Industry’s First 8-port
External SAS Controller
The LSISAS3801E card enables large-scale
direct attach storage (DAS) arrays through eight
external 3Gb/s miniSAS ports, driving up to 244
Serial Attached SCSI (SAS) and Serial ATA (SATA)
devices. This host bus adapter supports large
capacity external server storage RAID and non-
RAID enclosures by connecting a PCI Express
bus with two external x4 SFF8088 miniSAS
connectors. LSISAS3801E doubles the perfor-
mance of dual channel Ultra320 SCSI HBAs and
is ideal for today’s data centers.
Cost-Optimization of
External Storage with SAS
As the rst-to-market leader in SAS, LSI is
providing more bandwidth to cost-optimized
external drive arrays. System integrators can
use the LSISAS3801E to build large-scale
storage array infrastructures that support both
SAS and SATA devices. By utilizing lower-cost
SATA drives for data backup and SAS drives
for mission-critical applications, end-users
will receive high-capacity, high-performance
data storage while enjoying an interrupt-free
high-activity environment. The performance
advantage and cost savings can be felt immedi-
ately when using the LSISAS3801E to develop a
tiered storage array.
Maximum External Bandwidth
in a Low-Prole Adapter
The LSISAS3801E oers two x4 miniSAS
external connectors, allowing unprecedented
external throughput in a low-prole HBA.
By reducing the height on this SAS card,
integrators have greater exibility to plug the
LSISAS3801E into servers as thin as 2U. These
adapters, with PCI Express, also capitalize on
maximum system performance for those
systems needing it.
SAS Connectivity from the Serial IO Experts
The LSISAS3801E is a part of the rst generation
of Serial Attached SCSI controllers. Successful
implementation of these serial adapters is
eortless because of LSI experience and know-
how. Having a supplier who fully understands
the physical, electrical and protocol requirements
of each new serial standard will reduce the time
for system bring-up and oer greater exibility
in system topography.
LSI has supplied cutting edge serial technology
to systems throughout the world for over six
generations, making LSI the most experienced
enabler of serial interconnect for storage in the
world. Integrators can be assured that their LSI
adapter provides the most advanced and robust
serial technology available in the market.
