Complementary SAS and SATA Technologies Offer New Levels of Scalability
and System Flexibility
MILPITAS, Calif., June 29, 2005-Maxtor Corporation (NYSE: MXO) announced today
it is now shipping the Atlas® family of disk drives, the fastest drives
in their class1, with the latest enterprise-class interface technology - Serial
Attached SCSI (SAS). The SAS interface allows SAS and SATA disk drives to be
configured in the same enclosure, enabling customers to mix and match high-performance
Atlas drives with high-capacity MaXLine® SATA drives to meet a broad range
of price, performance and capacity requirements. Maxtor pioneered the use of
high-capacity ATA disk drives in nearline and midline applications with its
MaXLine drives, the de facto standard in this market.
"Maxtor with their new Atlas SAS disk drives is among the leading vendors
helping to make the benefits of SAS - increased performance, scalability and
cost-effectiveness - a reality for customers," said Mark Pollard, vice president
of marketing at Adaptec. "The breadth of Maxtor's product line should help
customers match system configurations with their application requirements."
"We currently have Atlas SAS drives in qualification with global OEMs and
system vendors," said Brendan Collins, vice president of marketing, core
products at Maxtor. "We expect those customers to complete testing soon,
followed by volume shipments. The Atlas SAS drives, coupled with our MaXLine
SATA drives, combine to give Maxtor the industry's broadest SAS/SATA enterprise
drive portfolio."
Featuring a data transfer rate of 3.0Gb/s, the SAS interface brings
together the best features of other enterprise interfaces including:
• Dual ports - increases system availability by providing two
data paths to a drive
• Multi-initiator capability - enables multiple hosts to access
a drive simultaneously
• Point-to-point connectivity - improves system performance and
fault isolation capabilities
• Scalable bandwidth - via wide ports
• Scalability - more than 16,000 devices per SAS domain
• Full duplex capability - allows drives to simultaneously send
and receive for two different IO operations
• Rate matching - supports 1.5Gb/s SATA and 3.0Gb/s SAS devices
for optimal performance
• IOPS performance - up to 128 queue depth support
• SCSI investment protection - employs SCSI command set to maintain
compatibility with existing SCSI infrastructure
• Compatibility with SATA devices
SAS and SATA enterprise drives are complementary storage elements ideal for
the new SAS-based common infrastructure. SAS drives are designed for the most
demanding, mission critical applications while SATA drives are well suited
for nearline and other less demanding small and medium business applications.
Maxtor is a founding member of the Serial Attached SCSI Working Group that authored
the first draft of the SAS standard now managed by the ANSI T10 standards body.
Maxtor has worked extensively with leading system and component suppliers to
test compatibility of Atlas SAS drives with their products. For more information
