5. #C14LV 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

6. #C14LV 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. #C14LV 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. #C14LV 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. #C14LV Disk Types: ■ Mechanical/Magnetic (Hard) Disks ■ Solid State Drives (SSD) ■ NAND (Non-volatile) ■ DRAM ■ Enterprise Flash Drives (EFD) – SLC vs. MLC ■ Hybrid 9

10. #C14LV 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. #C14LV Ways to Attach Storage Subsystems: (continued) ■ Fibre Channel (FC) ■ iSCSI – don't forget your TOEs! ■ Unified and Converged Storage/CNAs ■ Infiniband 11

12. #C14LV 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. #C14LV 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. #C14LV 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
