    Background

        Data storage plays an essential role in today’s fast-growing data-intensive
        network services.
        Online data storage doubles every 9 months
        How much data is there?

             Distributed Information System: Storage Services



    How is a server connected to a storage?


           Direct k Attached Storage (DAS)
           Traditional SCSI bus architecture
            – Both physical transport and a protocol
            – Device drivers under the OS talk with SCSI devices
            – Parallel bus with 8 bits, 16 bits, 32 bits

           Problems:
            – Signal skew
            – Termination of unused ports
            – Number of devices connected to a SCSI bus: 15
            – Length limitation: 15-25 meters

           Distributed Information System: Storage Services



    Problem:


         Each new application server requires its own dedicated storage
         solution.




9
         Distributed Information System: Storage Services



 Solution:


       Simplify storage management by separating the data from the
       application server.

         Distributed Information System: Storage Services



 Benefits of storage networking:


       Consolidation
       Centralized Data Management
       Scalability
       Fault Resiliency


                                                            Network delays
                                                             Network cost



     Storage capacity/volume
       Administrative cost
       Network bandwidth

 Storage as a service




                                       SSP                        ASP



          Storage Service Provider                                 Application Service Provider

     Outsourcing: storage and/or applications as a service.
     For ASPs (e.g., Web services), storage is just a component.

 Storage Abstractions

        – relational database (IBM and Oracle)
              – tables, transactions, query language
        – file system
              – hierarchical name space with ACLs
        – block storage/volumes
              – SAN, Petal, RAID-in-a-box (e.g., EMC)
        – object storage
              – object == file, with a flat name space: NASD, DDS
        – persistent objects
              – pointer structures, requires transactions: OODB, ObjectStore




13
          Distributed Information System: Storage Services



 Current State-of-the-art

     Network Attached Storage(NAS)
     Storage accessed over TCP/IP, using industry standard file sharing
     protocols like NFS, HTTP, Windows Networking
        Provide File System Functionality
        Take LAN bandwidth of Servers

     Storage Area Network(SAN)
     Storage accessed over a Fibre Channel switching fabric, using
     encapsulated SCSI.
        Block level storage system
        Fibre-Channel SAN
        IP SAN
           – Implementing SAN over well-known TCP/IP
           – iSCSI: Cost-effective, SCSI and TCP/IP

 Typical NAS




16
       Distributed Information System: Storage Services



 High BW NAS




       •Accelerate applications
       •Data sharing for NT, UNIX, and Web
       •Offload file sharing function



17
          Distributed Information System: Storage Services



 Typical SAN




     •Backup solutions (tape sharing)
     •Disaster tolerance solutions (distance to remote location)
     •Reliable, maintainable, scalable infrastructure

 More about Storage Virtualization

     • Storage virtualization is an
       intelligent “layer” or
       abstraction that pools
       storage from multiple storage
       devices into a common
       storage pool.

     • Often part of a storage area
       network (SAN), virtualized
       storage appears as one
       device to the server-
       operating systems and can
       be centrally managed and
       provisioned from a single
       view.                                         Source: IBM

 • Virtualized and Autonomic – Storage for an on demand operating

     processes and assist customers in lowering total costs. Improving organizational
     agility and lowering costs in a storage environment can be accomplished in two
     ways.
        • By providing virtualization capabilities, complexity can be reduced by treating
           storage and IT resources as single, common pool of resources.
        • Autonomic capabilities can be used to help simplify management and
