  2. Data Reliability/Integrity • Requirements • Bits-In == Bits-Out, forever • Challenges • Device sophistication creates “corruption opportunities” • Protection Boundaries in device: may be vulnerable • Increased SW/FW footprint and complexity: susceptibility • Data movement and migration will occur below application level • Short-Term Solutions • INCITS/T10 “Protection Information Model” will help much • End-to-End data protection for block devices • Data tags established at host, maintained in target • Longer-Term Opportunities • Extend protection model upward into the application stack • Define/standardize richer “application tags” for data • Move beyond “data block focus” LSI Proprietary

  3. Data Storage Security – In-Flight & At-Rest • Requirements • Restrict data access to authorized parties • Encrypt data-in-flight and data-at-rest for security, integrity, theft protection, etc. • Technical Solution • HW Accelerated Network connections at wire-speeds (10Gb/s) with proven encryption standards such as iPSEC & iPV6 • RAID Controller IOC Based Encryption (Custom) • Full Disk Encryption (specification in TCG) • Industry-standards for storage devices • Short-Term Challenges • Silicon intensive HW encryption engine cost • Controller based Encryption issues: • Everyone in the chain must use common keys and methods • When IOC encrypts T10-DIF data the drive can’t check the DIF • Authentication of storage device without user input • Industry-standards for Key Mgmt interfaces • Long-Term Challenges • Increasing Network speeds 10Gb/s >>> 100Gb/s • Key Mgmt for long-life archives • Encryption improvements for long-ago-saved data LSI Proprietary

  4. Power Efficient Storage • The storage industry is starting to invest in power optimization initiatives • The Green Grid (www.thegreengrid.org) • The SNIA Green TWG (www.snia.org) • SMIS (Storage Management Initiative – SNIA) (www.snia.org/smi/home) • SBB (Storage Bridge Bay) (www.sbbwg.org) • ASHRAE (American Society of Heating, Refrigeration, and Air Conditioning Engineers) (www.ashrae.org) • Many untapped opportunities for efficient storage architectures • Focus on intelligent DML (Data Management Layer) Storage Virtualization features • Introduce Modern High efficiency Power Supply and cooling architectures – 90% efficiency from 20% to 100% • Multi-core processor utilization - Taking advantage of multi-core with even lower frequency CPUs • System level power monitoring capability w/ dynamic CPU, Memory, HDD …etc resource management • Multi-System clustering and workload sharing to insure 100% system utilization • Use of small form-factor and SSD storage devices • Collaborate with IT Data-Center low-power standards LSI Proprietary

  5. SSD Based Storage • Why SSD? • Transactional reference data (< 500 GB) • Blade boot disks (RAID 1) • Enterprise Transaction Processing Random IOPs • Complete the Tiered Storage Hierarchies • Green computing (As price will allows) • Requirements: • Price: $/GB needs to be <= 3x SAS 15K HDD • Interface: SAS 6G target (W/ SATA3 support) • Performance: • Random R/W IOPs => 10x-50x FC/SAS 15K • Bandwidth LB R/W => 2x-4x FC/SAS 15K • $/IOPS <= 50% more than FC/SAS 15K • MTBF => 2M hrs • Launch date: 1H08 • Concerns: • Usability and Manageability • Long Term Data-Retention • Lack of HDD experience of most suppliers • Advanced features (security, T10-DIF ...etc) LSI Proprietary
