zOS - TS7720/TS7740 Grid: Cooperative Replication   Copy management uses information to optimize long-distance copy links

–  For deferred mode copies –  Prioritizes getting one copy to each family before making copies to members in a

family –  Executes single copy between families, then local copies between family members

  Enhanced bandwidth utilization –  Reduces redundant copy tasks moving data between sites

zOS - TS7720/TS7740 Grid: Automatic Removal Policy

 Provides automatic data migration function between the TS7720s and other TS7700s in the grid –  Manages copies between TS7700 clusters just like TS7700 HSM

component manages data in a TS7700 cache –  Only keep the most recently accessed or most important content in the

limited capacity TS7720 clusters –  Allow older or less active data to only reside on the TS7740 clusters

which contain back end tape

zOS - TS7720/TS7740 Grid: Extended Removal Policies  Configurable Volume Migration Settings

– “Pinned” – These volumes remain pinned in the TS7720 cache (except when scratched). – “Prefer Remove” LRU Group 0 and “Prefer Remove” Group 1 – As the TS7720 reaches full

capacity, these volumes will be automatically removed in LRU order favoring those in Group 0 over those in Group 1. Only volumes that have completed peer copies are candidates for removal.

•  Minimum Retention Time – Associated pin duration or grace period where data must exist prior to removal. Only after the pin time has elapsed since last access will the LRU Group 0 and 1 volumes become candidates for removal.

– Fast Ready/Scratch Volumes – When removal takes place, volumes that have been returned to scratch are always preferred first. This includes both “Pinned” and “LRU Group 0/1” volumes.

 Removed volumes remain accessible through all clusters – Grid links are used to remotely access the volume data in other TS7700s if locally removed.

ProtecTIER ProtecTIER

  Managed using system-managed tape (SMStape)

–  No JCL changes required

  Appears to the host as an automated tape library with 3592 Model J1A devices supporting MEDIA5 cartridges

  No host application or tape management changes needed

  Integration with the TS7680 during return to scratch processing to free backend cache

  Host alerts when cache starts to run low (warning and critical state notification)

  Single frame implementation is easy to install

Overview of IBM Tape Virtualization Options for zOS

Product Key Strengths Ideal customer profile(s)

TS7740 Grid and tight tape integration  Traditional large MF environments

 Multisite (2, 3 and 4 way Grids) TS7720 Grid and tape integration (2010,

via TS7740) with large, low cost cache

 Environments requiring fast access and intermediate storage requirements

 Suitable for those needing tapeless

VTFM  Performance, and ability to use standard DASD

 SW model allows flexibility

 Mid-range customers with tape-bound processing issues (inability to meet batch window) and/or looking for low cost entry

TS7680 Local high availability via clustering, high performance, excellent TCO with delta-based native IP replication

 Customers not requiring tape

 Large cache at low TCO

 HA

 Native IP replication for DR

Open (and zLinux) - LTO Roadmap

http://ultrium.com/technology/roadmap.html


Open - 04/2010: LTO Generation 5 Highlights

  Fifth Generation of LTO Tape Drive –  140 MB/sec performance native data transfer rate –  1.5 TB capacity (up to 3.0 TB at 2:1 compression) –  Encryption capable –  Media partitioning –  SAS at 6 Gbit/sec –  FC at 8 GB/sec –  Form Factor : Full Height and Half Height –  Capability to Read/Write Ultrium 4 and read

Ultrium 3 cartridges

–  IBM Long Term File System •  Available on External drives only

  Platform Support –  IBM System x, System p –  Selected platforms from HP and Sun Microsystems –  Selected versions of Microsoft Windows™ and Linux –  zLinux


Open - LTO5 and LTFS

  IBM Long Term File System is based on: 1.  Partitioning LTO-5 tapes in two partitions

•  Partition 1: Index Partition is “small” (2 wraps, 37.5 GB) •  Partition 2: Data Partition fills the remainder of the tape   Approved by LTO consortium

2.  Open LTFS Format which is written to tape •  Describes the format of data and meta data •  Meta data is based on XML schema   Developed and disclosed by IBM

3.  Open source LTFS software •  externalizes the LTO-5 tape as file system •  Software uses two partitions on LTO-5 tape to write LTFS format   Available on Linux and Mac OS X (planned for windows)


Open - LTO5 and LTFS


Open - 09/2010: Real Time Compression (RTC) for NAS


Future: 35 TByte/cart - demonstrating 29.5 Gb/in2

This demonstration shows that tape can sustain the roadmap for at least another decade while maintaining a cost advantage over other storage technologies.
