2. 2 LSI Proprietary 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”

3. 3 LSI Proprietary 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

4. 4 LSI Proprietary Power Efficient Storage The storage industry is starting to invest in power optimization initiatives –The Green Grid (www.thegreengrid.org)www.thegreengrid.org –The SNIA Green TWG (www.snia.org)www.snia.org –SMIS (Storage Management Initiative – SNIA) (www.snia.org/smi/home)www.snia.org/smi/home –SBB (Storage Bridge Bay) (www.sbbwg.org)www.sbbwg.org –ASHRAE (American Society of Heating, Refrigeration, and Air Conditioning Engineers) (www.ashrae.org)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

5. 5 LSI Proprietary 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)
