1 2009 DMTF Alliance Partner Technical Symposium SNIA Technical Activities Overview Paul von Behren SMI TSG FtF Mar 2009 Chart 1

2 SNIA Overview develop robust solutions for storing and managing the massive volumes of information generated by today s businesses SNIA older than 10 years Marketing activities and technical work In some cases, SNIA provides work-space for standards associated with other organizations In other cases, SNIA is the home for standards SMI TSG FtF Mar 2009 Chart 2

3 Common RAID Disk Data Format (DDF) Specification Common RAID Disk Data Format (DDF) Specification The Common RAID Disk Data Format specification defines a standard data structure describing how data is formatted across the disks in a RAID group. The Disk Data Format (DDF) structure allows a basic level of interoperability between different suppliers of RAID technology. The Common RAID DDF structure benefits storage users by enabling data-in-place migration among systems from different vendors. SMI TSG FtF Mar 2009 Chart 3

4 Common Trace Semantics Specification Common Trace Semantics Specification The Common Trace Semantics Specification defines common, recommended semantics for data in I/O traces. Standardized I/O trace semantics will enable the development and use of common I/O trace collection and analysis tools as well as facilitate the sharing of the I/O traces themselves. SMI TSG FtF Mar 2009 Chart 4

5 Common Trace Format Specification Common Trace Format Specification The Common Trace Format Specification defines standard formats for different types of I/O traces. Standardized I/O trace formats will enable the development and use of common I/O trace collection and analysis tools as well as facilitate the sharing of the I/O traces themselves. SMI TSG FtF Mar 2009 Chart 5

6 Data Integrity Specification Data Integrity Specification The Data Integrity Specification defines a standardized means of providing end to end data integrity between an application and storage devices. API for storage application (file systems, database mangers, volume mangers) to communicate with driver interfaces related to T10 (SCSI) data integrity capabilities SMI TSG FtF Mar 2009 Chart 6

7 extensible Access Method (XAM) Specification extensible Access Method (XAM) Specification Application to storage interface Empowers meta-data to instrument the automation of informationbased management Gives applications a standard interface and metadata to communicate with object storage devices such as those characterized as "Fixed Content Aware Storage interoperability, storage transparency, and automation for ILM-based practices, long term records retention, and information assurance (security) SMI TSG FtF Mar 2009 Chart 7

8 Green Storage Metrics Specification Green Storage Metrics Specification Identifies metrics by which energy consumption and efficiency of storage networking products can be measured for the purposes of new product development, end-user customer evaluation, and regulatory standards development Collaboration with work in DMTF SMI TSG FtF Mar 2009 Chart 8

9 iscsi Management API (IMA) iscsi Management API (IMA) The iscsi Management API defines a standard interface that applications can use to perform iscsi management independent of the vendor of the iscsi HBA. The IMA was designed to be implemented using a combination of a library and plugins. SMI TSG FtF Mar 2009 Chart 9

10 Multipath Management API (MMA) Multipath Management API (MMA) The Multipath Management API allows a management application to discover the multipath devices on the current system and to discover the associated local and device ports. An implementation of the API may optionally include active management (failover, load balancing, manual path overrides). Loose relationship to SMI-S Host Discovered Resources Profile SMI TSG FtF Mar 2009 Chart 10

11 Object-Based Storage Device (OSD) Specification Object-Based Storage Device (OSD) Specification The OSD specification defines low-level storage device functions that enable accessing a storage device through a standard object interface rather than a traditional block-based interface such as SCSI or IDE. The OSD specification is published through INCITS T10 as part of the SCSI standard. SMI TSG FtF Mar 2009 Chart 11

12 Object-Based Storage Device (OSD) Specification Self-Contained Information Retention Format (SIRF) Specification A means to interpret content into the future A specification that defines a logical container format appropriate for the long-term storage of digital information. Both physical and logical preservation efforts A CASPAR collaboration (EU co-funded program) SMI TSG FtF Mar 2009 Chart 12

13 Storage Management Initiative Specification (SMI-S) Storage Management Initiative Specification (SMI-S) SMI-S defines a method for the interoperable management of a heterogeneous Storage Area Network (SAN) Uses CIM Lots of Collaboration with DMTF General direction, SNIA is creating storage profiles Migration process moving legacy non-storage profiles from SMI-S to DMTF SMI-S bring implementation experience enhancements to DMTF E.g., View Classes SMI TSG FtF Mar 2009 Chart 13

14 SMI-S & other SNIA projects SMI-S documents relationship between CIM model and management aspects of underlying SNIA APIs Multipath Management API iscsi Management API Work in progress to bring into SMI-S Green metrics XAM Emerging Solid State Storage technical work SMI TSG FtF Mar 2009 Chart 14

15 SNIA Software NDMP V4 Software The NDMP V4 Software is a SNIA Software development project that implements version 4 of the NDMP standard, including extensions to the standard. XAM Software Development Kit The XAM Software Development Kit (XAM SDK) is a SNIA Software development project that implements the XAM Specification, an industry standard for fixed content storage.

16 OTHER TECHNICAL ACTIVITIES I/O Traces & Tools and Analysis (IOTTA) Repository The I/O Traces, Tools and Analysis (IOTTA) TWG has created a worldwide repository for I/O trace collection and analysis tools, application workloads, I/O traces of workloads, and best practices around such topics. The repository is located at SMI TSG FtF Mar 2009 Chart 16
