Visit IOUG at the User Group Pavilion • Stop by at the User Group Pavilion in the lobby of Moscone South and catch up with the user community!  • Connect with IOUG members and volunteers • Pick up a discount to join the IOUG community of 20,000+ technologists strong • Enter for the chance to win books from IOUG Press or a free registration to COLLABORATE 15! Visit us Sunday through Wednesday!

  5. Overview • A Brief History of Storage • The Dominant Disk Protocols • The Dominant Storage Configurations • Disk Types • Ways to Attach Storage Subsystems • Filesystems • Latest Technologies 5

  6. A Brief History of Storage: • Paper “Punch” Cards (still in use!) • Paper Tape (obsolete) • Magnetic Reel Tape (obsolete (almost)) • Hard Disks IBM 305 RAMAC → • Cartridges (DLT, Travan, Ditto, LTO) • “Super Floppies” (Bernoulli, Zip, LS-120) (obsolete) • Removable HD (Jaz, SyQuest) (obsolete) • Magneto-optical (MiniDisc) (low adoption) • Optical (CD, DVD, Blu-ray) • SSD & other memory-based storage • Caching technologies 6

  7. The Dominant Disk Protocols: • (P)ATA – (Parallel) Advanced Technology Attachment (obsolete) • SATA – Serial ATA • SCSI – Small Computer System Interface (parallel) (dying) • SAS – Serial Attached SCSI (replacing SCSI) • Fibre Channel (serial) – the next to die? • There are others, such as SSA, but they are not common Why Serial over Parallel? Isn't Parallel faster? 7

  8. The Dominant Storage Configurations: • RAID – Redundant Array of Inexpensive Disks • Striping (anything ending in a zero) • Mirroring (anything with a 1 in it) • Parity (everything else) • Tiered Storage • Elastic Storage These are not mutually exclusive! In fact the best subsystems make all of them available. However, some vendors handle these automatically, or with minimal user input. 8

  9. Disk Types: • Mechanical/Magnetic (Hard) Disks • Solid State Drives (SSD) • NAND (Non-volatile) • DRAM • Enterprise Flash Drives (EFD) – SLC vs. MLC • Hybrid 9

  10. Ways to Attach Storage Subsystems: • Direct Attached (DAS) • Network Attached Storage (NAS) • Network File System (NFS) • Server Message Block (SMB, aka CIFS and Samba) • Storage Area Network (SAN) 10

  11. Ways to Attach Storage Subsystems: (continued) • Fibre Channel (FC) • iSCSI – don't forget your TOEs! • Unified and Converged Storage/CNAs • Infiniband 11

  12. Filesystems: • Normal (Cooked) Filesystems – hundreds of them! • Raw • Automatic Storage Management (ASM) • Clustered Filesystems • QFS (Sun) and VxFS (Veritas) • OCFS/OCFS2 • ACFS (aka ASMFS) • DBFS • ZFS – Filesystem, LVM, and Tiered/Elastic storage all in one, plus snapshots So what's the downside? CDDL vs. GPL. Say hello to Butter (Btrfs) someday... 12

  13. Latest Technologies: • Tiered Storage – Excellent starting point for SSD adoption • Data Deduplication – Think about compression and encryption issues • Elastic/Thin Provisioned Storage – Requires a new tool, ASRU • Direct NFS – Solving the async I/O problem 13

  14. Latest Technologies: (continued) • Infiniband – Ideal for cluster interconnect, and now storage • Exadata Hybrid Columnar Compression • Storage in the Cloud • Cache-on-HBA (Qlogic QLE10000) • Fusion-IO – as fast as it gets The great storage paradigm-shift is on! 14
