Heterogeneous Storage Management using SMI-S and CIM
John HarkerHitachi Data Systems
September 12-14, 2005 • Marriott Bethesda North Conference Center • Bethesda, Maryland
Agenda
• The Customer Problem
• How and why standards play into this– DMTF, CIM, WEBM, SNIA and SMI-S,
WMI and WMX
• Storage Management– Understanding and managing your
infrastructure
• Data Management– Virtualized tiered storage
• What’s still needed

Storage Management Standards
The need for standardized management is driven by IT customers who want to manage all their systems - standalone, rack mount bricks, blades, and storage - using the same tools. This requires a focus on the intersection of open management standards in the server and storage areas.
September 12-14, 2005 • Marriott Bethesda North Conference Center • Bethesda, Maryland
SNIA and DMTF• SNIA is a vendor-neutral trade organization and ALSO a standards body:
– Fast-tracking of standard proposals through INCITS/ANSI• SMI_S v1.0.2 is ANSI INCITS 388-2004
– On-going standard projects include:• IP Storage • Shared Storage Model• Storage Management• Storage Security• Data Management
• SNIA contributes to the development of the DMTF CIM standard – Many object and schema changes/extensions in the CIM Specification
are the result of SNIA Change Requests• SNIA Technical Working Groups are working to extend the DMTF Common
Models to achieve a comprehensive Storage Management Specification (SMI-S)
September 12-14, 2005 • Marriott Bethesda North Conference Center • Bethesda, Maryland
SNIA Storage Management Initiative• Storage Management Initiative (SMI) and the Storage Management Initiative
Specification (SMI-S)– Represents the efforts of the SNIA teams driving towards the first
common and interoperable management standard for storage networks– Entirely based on CIM and WEBM
• SMI-S enhances CIM and WEBM by– Introducing “profiles” that precisely define what classes and fields are
required, and how the CIM classes interact – Defining Profiles for array, fabric, hosts, tape library, virtualization, and
volume managers.– Defining other necessary components to ensure interoperability –
transport, security, discovery, installation, upgrade • SMI-S Status
– Version 1.0.2 commercial, 1.1 final, 1.2 out for review - http://www.snia.org/smi/home)
– Tested during SNWs and at plugfests– SNIA Colorado SMI-S Interoperability Lab– Test program in place to certify SMI-S compliance (SNIA-CTP)– SMI-S Certification test suites – provider and client side
September 12-14, 2005 • Marriott Bethesda North Conference Center • Bethesda, Maryland
Notes on Commercial CIM Implementations
• WMI is a Windows-based implementation of the DMTF Web-Based Enterprise Management (WBEM) initiative, and is fully compliant with the DMTF CIM version 2.0 management schema definitions. But…– Using Microsoft DCOM for communications
transport– Using Microsoft Active Directory and Security
systems• IBM AIX, Sun Solaris, Linux WEBM implementations
use different CIM implementations – some Java, some C++
• Pretty much they don’t talk.

HiCommand Storage Services Managerpowered by AppIQ
Hitachi Data Systems HiCommand Storage Services Manager is a SMI-S based Storage Management system
•Designed to SMI-S, uses CIM-based object model as the abstraction layer (CIMIQ-X)
•Uses SMI-S providers where available
•Wraps proprietary APIs in CIM/SMI-S where no SMI-S is available
•Can consume from (be a client to) both SMI-S and CIM providers
•Communicates with both WEBM and WMI using appropriate transports

SNIA Data Management Initiative• SNIA Data Management Forum is working in these areas
• Information Lifecycle Management• Data Protection Initiative• Long Term Archive and Compliance Storage Initiative
• ILM definition and vision– Information Lifecycle Management is comprised of the policies, processes,
practices, and tools used to align the business value of information with the most appropriate and cost effective IT infrastructure from the time information is conceived through it’s final disposition.
– Information is aligned with business requirements through management policies and service levels associated with applications, metadata, and data.
• ILM’s goal - Storage Management Interface (SMI)– A new set of management practices– A new set of data-centric standards based on SNIA’s SMI-S– Currently SMI-S defines a set of access modes to a StorageExtent and replication
functions in CopyServices– More is needed & being worked on to cover additional considerations in overall data
lifecycle. This will take a while …

Application Optimised Storage Step 1: Data vs. Application Classification
• Everyone agrees that proper Data Classification is a fundamental component in any Storage Tiering initiative.
• However, if you attempt to classify every application and file in your environment today:
– It will be laborious and may take years to complete– You will end up with too many classes and policies– It will be difficult to implement in a reasonable timeframe
• Consider “Application Classification” instead– Select your top 3 to 5 business applications to start– Identify Applications with the highest ROI– Demonstrating results quickly will validate the project

September 12-14, 2005 • Marriott Bethesda North Conference Center • Bethesda, Maryland
Application Optimised Storage Step 1: Application Classification
•There are at least 4 basic categories that classify any application:
– Availability Uptime requirements, often measured in 9’s– Performance Response Time– Protection Replication (Local and Remote) and Backup– Retention/Compliance Archive and Locking capability
•The output from these requirements will determine the classes of storage and associated Service Levels needed
September 12-14, 2005 • Marriott Bethesda North Conference Center • Bethesda, Maryland
Application Optimised Storage Step 2Service Level Definition (Examples)
• Platinum Service or Class A: This should be provided to your most critical Business applications because it provides the highest level of Availability, Performance and Protection
• Gold Service or Class B: High Availability, Acceptable Performance and Recoverability tolerance of 1 to 5 hours
• Silver Service or Class C: Business Essential but not as critical
– Low Cost drives (performance and availability) and Tape backup for recovery are acceptable
September 12-14, 2005 • Marriott Bethesda North Conference Center • Bethesda, Maryland
• Key to Infrastructure Selection: – Efficient, optimized and scalable– lowest possible costs and risks to meet your service levels– FLEXIBLE and DYNAMIC
• Business requirements are constantly changing and will drive application requirements throughout their lifecycle.
– Data requiring High Performance and availability today, may not need it tomorrow, but may require it again at month end.
• Dynamic Tiering in place you can further optimise applications– By tiering active vs. inactive data within applications. Having this
flexibility, will allow you to react quickly, optimize performance and minimize backup windows and REDUCE COST.

Distributed Environment Standards• There are still numerous gaps in SMI-S & CIM
• Current products supporting CIM usually are stovepiped on top of their own CIM stack (e.g. no cross shared directory, security, etc.)
• The web services standards community (WW3, DMTF, Oasis) and the grid computing standards community (Globus) are standardizing on a common set of Internet based standards for distributed services (IPC, directory, security, data formats, events). These will be important in solving the stovepiping problem for both remote management and for commercial application support.
September 12-14, 2005 • Marriott Bethesda North Conference Center • Bethesda, Maryland
• Hitachi is committed to contributing extensively to both DMTF and SNIA • Hitachi agrees that extensions are required to cover additional considerations
in the overall data lifecycle and had made proposals in several* of those areas:
• additional extent protection modes*• a retention period defining how long the protection mode MUST stay in
effect• the definition of behaviors and constraints related to retention periods• non-disruptive extent migration*• maintenance of protection modes through replication and recovery• reclamation services to implement storage extent shredding and reuse
after migration and final data deletion*
