Availability, Scalability, Flexibility, Reliability, Adaptability and Leading
Edge Performance—The Atlas 15K II SAS Strengths
The Maxtor® Atlas 15K II SAS combines a 16MB cache, 98MB/s sustained data
transfer rates and as fast as 3.0 msec seek times with the latest Enterprise interface
technology—Serial Attached SCSI (SAS). Atlas 15K II drives deliver the required
IOPS (input/output per second) performance to support transactional
and IO intensive applications. Its sustained data rate makes it the ideal
drive for high-bandwidth applications.
SAS technology brings together the best
features of other Enterprise interfaces to
deliver:
Higher System Availability
• Dual port provides two data paths to each
drive increasing the drive’s availability
• Multi-initiator capability enables multiple
hosts to access a drive simultaneously
• Point-to-point connectivity for better fault
isolation
Scalability
• More than 16,000 devices per SAS
domain
• Scalable bandwidth via wide ports,
i.e. up to 24 Gb/s peak bandwidth with
4 SAS links configured as a wide port
with full duplex
End User Flexibility
• Configuration flexibility allow end-users to
mix and match SAS and SATA drives to fit
their specific application
• SAS back-planes can accommodate dual
port / high performance SAS drives and/or
high capacity / lower cost SATA drives
Performance
• Up to 128 queue depth support for
improved IOPS performance
• Full duplex capability allow drives to
send and receive data for two different IO
operations simultaneously
• Point-to-point connectivity eliminates the
bottleneck inherent with a shared/arbi
trated bus
• Scalable bandwidth via wide ports
• Rate matching supports 1.5Gbs SATA
and 3.0Gbs SAS drives for optimal
performance
SCSI Investment Protection
• Employs the SCSI command set to
maintain compatibility with existing
SCSI infrastructures
Atlas 15K II SAS Hard Drives Deliver:
MaxAdapt Features
• Adaptive Bias Estimation (ABE)—
Maintains consistent performance by
adjusting the bias applied to the actuator
• Virtual Cache Lines (VCL—Allows
dynamic assignment of cache segments
• Rotational Vibration Compensation
(RVC) —Monitors and corrects for
external vibration
Reliability
• 1,400,000 hours MTTF
• State-of-the-art manufacturing processes
• Multiple temperature tests
• Improved SMART and self-diagnostics

• Large Enterprise NAS/SAN
• Servers
• Mainstream NAS/SAN
• Workstations
• Direct Attached JBOD Storage
• Direct Attached RAID Storage
