  • 1. Sun StorageTek™ 2500Series Arrays -Technical Presentation Presenter Title Sun Microsystems, Inc.
  • 2. Challenges for Todays 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 Sun Proprietary/Confidential: Internal Use Only Page 2
  • 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 environmentsSun Proprietary/Confidential: Internal Use Only Page 3
  • 4. Customers Telling Us They Need • 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 Sun Proprietary/Confidential: Internal Use Only Page 4
  • 5. Sun StorageTek™ Modular LineSolutions that provide streamlined management, flexiblity, & TCO Sun StorageTek™ Sun StorageTek™ 6540 array 6140 array Ideal for New! database-driven applications Sun StorageTek™ Leader in 2500 arrays price/performance Enterprise-class Excels in HPTC data protection environments on a budget Multi-tiered storage Affordable entry Replication point within Modular target family of arrays Support for variety of host interface options Sun Proprietary/Confidential: Internal Use Only Page 5
  • 6. 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 subsystemproviding consolidated RAID to FC or SAS host interfaces Sun Proprietary/Confidential: Internal Use Only Page 6
  • 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 Sun Proprietary/Confidential: Internal Use Only Page 7
  • 8. SAS Deployments Motherboards SAS ICs HBAs RAID adapters SwitchesSAS Expanders RAID controllers Drives Sun Proprietary/Confidential: Internal Use Only Page 8
  • 9. SAS: Superior to Parallel SCSI• 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 1 2 3 4 > Allows for data to be received 1 2 3 4 and transmitted at the same time > Scalable > Freedom from 15 drive maximum per SCSI channel > SAS and SATAProprietary/Confidential: Internal Use Only supports tiered storage Sun drive compatibility Page 9
  • 10. SAS: Superior to Parallel SCSI Parallel SCSI SAS Architecture Parallel, all devices connected to a shared bus Serial, point-to-point, discrete signal paths 320 MB/s (Ultra 320 SCSI); performance 3.0 Gb/s, roadmap to 12.0 Gb/s; performance Performance degrades as devices added to shared bus maintained as more drives added Scalability 15 drives Over 16,000 drives Compatibility Incompatible with all other drive interfaces Compatible with Serial ATA (SATA) 12 meters total (must sum lengths of all cables 8 meters per discrete connection; total domain Max cable length used on bus) cabling 100+ meters Cable form factor Multitude of conductors adds bulk, cost Compact connectors and cabling save space, cost Hot pluggability No Yes Manually set, user must ensure no ID number Worldwide unique ID set at time of manufacture;Device identification conflicts on bus no user action required Manually set, user must ensure proper installation Discrete signal paths enable devices to include Termination and functionality of terminators termination by default; no user action required Sun Proprietary/Confidential: Internal Use Only Page 10
  • 11. Understanding SAS “Wide” Ports• 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 Sun Proprietary/Confidential: Internal Use Only Page 11
  • 12. Drive Performance Comparison• IOPS > Random, small-block transfers > OLTP, databases, Exchange > Majority of enterprise applications 15K SAS > Key drive-based performance enablers: > Seek time, latency, rotational velocity, IOPS -- SAS ~100% of 15K FC command queuing, number of drives• Throughput > Sequential, large-block transfers > Video servers, rich media, seismic processing, HPC 10K SAS > Key drive-based performance enablers: Throughput -- SAS ~100% of FC > Data transfer rate, maximum I/O transfer size, command queuing Use Only Sun Proprietary/Confidential: Internal Page 12
