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
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

SAS Overview
• SCSI is in its 7th 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
> Freedom from 15 drive maximum per SCSI channel> SAS and SATA drive compatibility supports tiered storage

SAS Overview, continued
Drive technology
• Point-to-point architecture> Provides direct contact with each drive> Drive isolation locates and remedies drive problems more quickly vs. loop
topology where communication must travel through each node
• Dual-porting > Redundant data paths to each drive maintains connectivity should one link fail

ST2500 Capacity Expansion
When attaching enclosures, drive channels are configured as redundant pairs utilizing one connector from each controller and “top-down/ bottom-up” cabling. This helps ensure data access in the event of a path/channel or controller failure.
