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)
