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 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 LSI Proprietary Power Efficient Storage The storage industry is starting to invest in power optimization initiatives –The Green Grid ( –The SNIA Green TWG ( –SMIS (Storage Management Initiative – SNIA) ( –SBB (Storage Bridge Bay) ( –ASHRAE (American Society of Heating, Refrigeration, and Air Conditioning Engineers) ( 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 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)
