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”

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

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

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)
