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


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


• 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


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 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> Scalable

> Freedom from 15 drive maximum per SCSI channel> SAS and SATA drive compatibility supports tiered storage

SAS: Superior to Parallel SCSIParallel SCSI SAS

Architecture Parallel, all devices connected to a shared bus Serial, point-to-point, discrete signal paths

Performance

Scalability 15 drives Over 16,000 drives

Compatibility Incompatible with all other drive interfaces Compatible with Serial ATA (SATA)

Max cable length

Cable form factor Multitude of conductors adds bulk, cost Compact connectors and cabling save space, cost

Hot pluggability No Yes

Device identification

Termination

320 MB/s (Ultra 320 SCSI); performance degrades as devices added to shared bus

3.0 Gb/s, roadmap to 12.0 Gb/s; performance 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 usedin one of two ways> Round robin down each lane> Designated primary> “Overflow” when concurrent

I/Os overload the previous channel

Understanding SAS “Wide” Ports


• IOPS> Random, small-block transfers

> OLTP, databases, Exchange> Majority of enterprise applications

> Key drive-based performance enablers: > Seek time, latency, rotational velocity,

command queuing, number of drives

• Throughput> Sequential, large-block transfers

> Video servers, rich media, seismic processing, HPC

> Key drive-based performance enablers: > Data transfer rate, maximum I/O

transfer size, command queuing

Throughput -- SAS ~100% of FC

When connecting the ESM, the “out: connector of one ESM must be cabled to the “in” connector of the next enclosure’s ESM

ST2500 Drive Side Expansion• When attaching

enclosures, drive loops are configured as redundant pairs utilizing one port from each controller. This helps ensure data access in the event of a path/loop or controller failure.
