  • This, again, is the SONAS Value propositions. Thank you!
  • IBM Real-time Compression consists of 35 patents that are not about compression at all but how to make compression both real-time and random access. The IBM Real-time compression leverages industry standard Lempel-Ziv compression algorithms allowing users to get up to 80% optimization efficiency in their storage reducing their overall cost per GB. As I mentioned before the IBM Real-time compression IP is all about how to make LZ compression real-time and random access, and by doing so it ensures that there is no impact to performance. And finally, the IBM Real-time Compression Appliance for NAS installs transparently in front of your existing IP based storage with out requiring any changes to your applications, servers, networks or storage.

    2. 2. NAS 101: An Introduction into Network Attached Storage Session ID: sCR07
    3. 3. Richard Swain, IBM NAS Specialist <ul><li>14 years Experience in IT </li></ul><ul><li>Certified NAS Specialist </li></ul><ul><li>Netapp Certified Technologist </li></ul><ul><li>Microsoft Certified Professional </li></ul><ul><li>Networking, Exchange, SQL, ERP, Storage </li></ul><ul><li>Blog: www.ibm.com /blogs/IBMNAS </li></ul><ul><li>Twitter: richswainWORK </li></ul><ul><li>[email_address] </li></ul>
    4. 4. <ul><li>SLOW </li></ul><ul><li>Complicated </li></ul><ul><li>Not secure </li></ul><ul><li>High Maintenance </li></ul><ul><li>Others? </li></ul>NAS Myths
    5. 5. Agenda <ul><li>Basics of NAS </li></ul><ul><li>Features </li></ul><ul><li>Limitations/Problems </li></ul><ul><li>Environments </li></ul><ul><li>Future of NAS </li></ul><ul><li>NAS @ IBM </li></ul>
    6. 6. Network Attached Storage (NAS) <ul><li>Remote file access across a set of UNIX machines in early 80’s </li></ul><ul><li>Novel released the NCP protocol in ’83 </li></ul><ul><li>SUN released NFS in ’84 </li></ul><ul><li>3Com was first to build a dedicated NAS </li></ul><ul><li>Auspex developed a dedicated NFS server for UNIX market </li></ul><ul><li>Early 90’s a splinter group of Auspex created NetApp unified platform </li></ul><ul><li>2000 was beginning of clustered NAS: IE Spinnaker, Exanet, ONStor, IBRIX, Isilon… </li></ul>
    7. 7. Definition <ul><li>A *computer* connected to a network that only provides file-based data storage services to other devices on the network. </li></ul><ul><li>Basic components: </li></ul><ul><li>Network (IP Based) </li></ul><ul><li>Directory Structure (Active Directory/NIS/LDAP) </li></ul><ul><li>Storage </li></ul><ul><li>OS </li></ul><ul><li>Protocol (NFS/CIFS/AFP) </li></ul><ul><li>Unified? </li></ul>
    8. 8. Difference in NAS vs SAN <ul><li>SAN is </li></ul><ul><ul><li>Block based </li></ul></ul><ul><ul><li>Appears as a disk drive to client </li></ul></ul><ul><ul><li>Can be formatted and mounted </li></ul></ul><ul><ul><li>Protocols:FCP, iSCSI </li></ul></ul><ul><li>NAS is </li></ul><ul><ul><li>File based </li></ul></ul><ul><ul><li>Appears as a file server to client </li></ul></ul><ul><ul><li>Does not require a host </li></ul></ul><ul><ul><li>Protocols: NFS, CIFS, AFP, FTP, HTTP </li></ul></ul>
    9. 9. How does NAS work? <ul><li>Storage is created </li></ul><ul><li>IP network (DNS, directory srvs) </li></ul><ul><li>Shares created / exported </li></ul><ul><li>Client browses to share </li></ul><ul><li>If credentials are correct access is given per the permissions on share </li></ul><ul><li>Data is then R W X D </li></ul>
    10. 10. How does NAS work? NAS server Directory Services Linux/Unix Workstation Windows Workstation Ethernet Environment
    11. 11. How does NAS work? Population Google Earth Salary Weather Web 2.0 Mashup
    12. 12. Shares and Directory Structure <ul><li>Shares can be at any directory level </li></ul><ul><li>Most companies use groups to share large amounts of data </li></ul><ul><li>User access is done at a granular level </li></ul><ul><li>Examples: servershare </li></ul><ul><li>xCompanyhomerswain </li></ul><ul><li>172.168.0.100rswain </li></ul><ul><li>Global Name Space helps keep the same server name </li></ul>
    13. 13. Issues with NAS <ul><li>No thin provision, must use quotas </li></ul><ul><li>Data has ‘texture’ called meta data, who what when where </li></ul><ul><li>As storage grows, controllers need to scale up or out </li></ul><ul><li>Lun locks blocks for applications, not same for share </li></ul><ul><li>Backups can take a while </li></ul>
    14. 14. Features that Make NAS More Manageable <ul><li>Snapshots </li></ul><ul><li>Global Name Space </li></ul><ul><li>ILM/HSM </li></ul><ul><li>Cross protocol access </li></ul>CIFS NFS
