Challenges for Today's IT
•Dealing with data growth and capacity
constraints with restrictive budgets
•Low storage utilization from stranded server
DAS storage leads to wasted space,
duplicated functions, and inefficient data
protection
•Provisioning the right class of storage for
the right application environment
•Dealing with the complexities of managing
storage
•Dealing with rack space constraints
•Reducing CAP-EX and OP-EX, improving
business operations

3. Sun Proprietary/Confidential: Internal Use Only Page 3
Emerging Applications
•Distributed database applications including
CRM, data warehousing/analytics, email –
requiring low cost, horizontal scaling storage
•Distribution, editing, and reception of
content pushing content closer to the edge
of the network
•Digital content including broadcast, video on
demand, multimedia, digital cinema
•Web 2.0 applications and services enabling
sharing, participation, and collaboration
•High performance compute and grid
environments

4. Sun Proprietary/Confidential: Internal Use Only Page 4
•Simple and common management
>Easy as provisioning their server
>Ease application optimization
•Small footprint
>For rack intensive server and
storage environments
•Strong performance to meet new
application demands without
sacrificing budgets
•Reliable data protection and
availability for the money

Positioning
The Sun StorageTek 2500 array
family is ideal as primary and
secondary storage for entry and
workgroup application
environments
It is based on a new low-cost SAS/SATA disk subsystem
providing consolidated RAID to FC or SAS host interfaces

7. Sun Proprietary/Confidential: Internal Use Only Page 7
SAS Defined
•Serial Attached SCSI (SAS) is a serial communication
protocol designed for transfer of data to and from devices
•The SAS standard defines a device-level enterprise storage
interface incorporating SCSI command sets, serial point-to-
point interconnections, dual-porting, increase addressability
and the ability to scale small form factors

•SCSI is in its 7
th
generation with the U320 SCSI and has
reached its final iteration
•Serial attached SCSI is the successor to parallel SCSI
>New roadmap and the industry behind it
•Benefits
>Better performance
>3 Gb/s SAS “x4 wide” ports provide
a cumulative bandwidth of 12 Gb/s
>Full duplexing
>Allows for data to be received
and transmitted at the same time
>Scalable
>Freedom from 15 drive maximum per SCSI channel
>SAS and SATA drive compatibility supports tiered storage

maintained as more drives added
12 meters total (must sum lengths of all cables
used on bus)
8 meters per discrete connection; total domain
cabling 100+ meters
Manually set, user must ensure no ID number
conflicts on bus
Worldwide unique ID set at time of manufacture;
no user action required
Manually set, user must ensure proper installation
and functionality of terminators
Discrete signal paths enable devices to include
termination by default; no user action required

•SAS lane is 3 Gb/s
>Path to drives is a single lane
•“x4 wide” creates 4 lanes
in a single connector
•Lanes are typically used
in one of two ways
>Round robin down each lane
>Designated primary
>“Overflow” when concurrent
I/Os overload the previous channel

enclosures, drive loops
are configured as
redundant pairs utilizing
one port from each
