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.

zOS - 05/2010: TS7720/TS7740 – Enhanced Disk Buffer
Two models provide high performance and capacity – Both support performance of 600MBps or greater
– TS7720 provides ~ 1200TB of native cache capacity (3:1 compression) • No attachment to back end tape except via Grid attachment to a TS7740
– TS7740 provides over 72TB of native cache capacity (3:1 compression) • Supports attachment to IBM TS1130, TS1120 or 3592 J1A tape drives • Supports tape drives in an IBM TS3500 or 3494 tape library • Supports TS1130/TS1120 data encryption

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

© 2010 IBM Corporation 16
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
© 2010 IBM Corporation 17
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)
