Virtual Tape Concepts


Product Development Objective

� Develop a subsystem that exploits the storage hierarchy– Supports the requirements for data written to virtual tape to address

• business continuity in the event of an outage, or/and• long term archival or regulatory legislation

– Matches the data to its access requirements• Fast access to data on ‘virtual volumes’ on the disk buffer• Cost effective storage by optionally migrating ‘virtual volumes’ to physical tape

– Provides the industries most flexible choices of technology to meet the

customer’s needs• Disk only virtual tape for those customer that do not require the presence of physical

tape or favor the large disk residency of a disk only solution• Disk and physical tape tightly integrated in order to tightly couple the benefits of disk

and physical tape to deliver performance for active data and best economics for inactive data

• Hybrid of both disk only and disk and physical tape solutions in order to handle all combinations in between

TS7700 Virtualization Engine Performance


Product Overview


TS7700 Virtualization Engine Overview

� Includes advanced architecture– Architecture designed to facilitate future enhancements– Advanced IBM technology to increase performance and capacity– Grid business continuity option to increase flexibility and reduce cost

� Two models provide high performance and capacity – Both can achieve 900 MBps for standard workloads– TS7720 provides ~ 1.3 PB of native cache capacity (3:1 compression)

• No attachment to back end tape except via Grid attachment to a TS7740

– TS7740 provides over 84TB of native cache capacity (3:1 compression)• Supports attachment to IBM TS1140, TS1130, TS1120 or 3592 J1A tape drives• Supports tape drives in an IBM TS3500 tape library• Supports TS1140/TS1130/TS1120 data encryption

� Synchronous Mode Copy¹– Provides true synchronous copy through real time duplexing (local mount and remote mount at the

same time)– Copy consistency at two locations up to any implicit or explicit sync point providing a zero recovery

point objective (RPO)• Up to two sites containing will be consistent after each implicit or explicit tape SYNC operation• Provides applications, such as DFSMShsm, dataset level replication (Zero RPO!)• When duplexing fails, downgrade to sync-deferred or fail job• LAN/WAN buffering will be used until SYNC points are reached• Additional Deferred and/or Immediate copies can occur once volume is closed

– Most optimal for DFSMShsm, DFSMSdfp OAM Object Support and other dataset or object stacking applications

Belongs to the R2.1 code1


Continued

� Remote Mount IP Link Failover¹

– Improved remote read/write operations by utilizing alternate links in the event of path

failure.

– Use redundant grid links for remote mounts for transparent failover

– If a failure occurs, the Failover path searches another IP link to continue the job, without

stopping or letting the host and customer realize it.

� Copy Export Acceleration¹

– New option which improves the speed of large copy export operations by reducing the

number of physical volumes which contain a copy of the database used for recovery

� Parallel Copies and pre-Migrations during Mounts for Read¹

– Current design cancels any active copy/migration activity on mounts for read

– New design allows copies and pre-migrations to occur in parallel to host mounts for read



Continued

� Copy Export Merge for Workload Moves¹

– Allow export restore to a system that is not empty

– Can be used to move content from one grid to another through copy export

� Grid Merge¹

– Merge two existing multi-cluster grids to form a single larger grid.

� Preferred Migration of Scratch Volumes¹,²

– Reduce use of cache for data unlikely to be read

– Favor the migration of previously scratched PG1 volumes before private volumes.

– Allows private volumes to be retained in disk cache longer.

Automatic Removal Policy

� Disk-centric and cost effective Hybrid Grid Configurations

� Automatic volume migration and cache space management of the TS7720´s cache

– Volumes are copied from a TS7720 to a TS7740 through normal copy policies

– When space is needed, the least recently accessed volumes in the TS7720´s cache that have been copied to a TS7740 are removed from the TS7720´s cache

� Migrated volumes remain accessible through the TS7720

– TS7720 uses the grid links to remotely access the volume data in the TS7740

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 Keep” 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.

TS7740 Cluster

LAN/WAN

�Three production TS7720 clusters all feeding into a common TS7740– Each TS7720 primarily replicates only to the common TS7740– Provides 1.3PB (4PB @ 3:1 compression) of HIGH PERFORMANCE production cache when running in balanced

mode– Each TS7720 has full access to all data contained within grid providing a fully HA solution– The installed TS7740 performance features can be minimal since host connectivity wouldn’t be expected

�Production data migrates into the TS7740– If a TS7720 reaches capacity, the oldest data which has already been replicated to the TS7740 will be

removed from the TS7720 cache.– Copy export can be utilized at the TS7740 in order to have a second copy of the migrated data.– Duration between copy exports can be longer since the last N days of data has not yet been migrated

Performance Considerations

� Peak write performance is the data rate available for a finite period1

– May be influenced by workload characteristics• Block size and Batch Window Characteristics• Processor and channel configuration

– May be influenced by customer data compressibility• Charts that follow reflect typical compression of 2.66:1• Customer data may compress at different ratios

� Sustained write performance is the data rate that can be sustained indefinitely1

– May be influenced by the same elements that impact peak write performance

� Peak read performance is the data rate available from the cache1

– May be influenced by the same elements that impact peak write performance

� Grid performance includes replication effects1

– May be influenced by the same elements that impact peak read/write performance – May be impacted by synchronization mode (Deferred / Immediate Copy)– May be influenced by network configuration / available bandwidth

The Value of Grid Interconnect Method

� Move from FICON to I/P based interconnections

� Integrate peering functions into base TS7700 Virtualization Engine

� Reduces infrastructure requirements

– Eliminates Virtual Tape Controllers

– Eliminates channel extension hardware

� Simplifies management

– Fewer elements to manage (no VTCs, channel extension hardware)

– Single management interface for standalone and Grid configurations


Ownership and Ownership Takeover Mode

� Volume Ownership in a Grid configuration

– Each logical volume is owned by a TS7700 cluster

– All changes to a volume are controlled by the owner

– A TS7700 cluster must have ownership of a volume to execute a mount operation

– Volume ownership is dynamically transferred between TS7700 clusters in a Grid configuration as

part of mount processing

� Ownership Takeover Modes

– If a TS7700 cluster that has ownership of a logical volume is unavailable, the Automatic Ownership

Takeover Manager allows the available TS7700 cluster to take ownership away from the

unavailable TS7700 cluster

– The Ownership Takeover Manager uses the TS3000 System Console (TSSC) on each TS7700

cluster to provide an independent method to check the status of a cluster

– If a failure has been confirmed, one of the ownership takeover modes is enabled automatically

• A default of Neither, Read or Write ownership is set by IBM Service


Copy Export – TS7740

� Export function to support transfer of data for offsite disaster recovery

� Exports a copy of selected data, leaving the primary copy in the TS7700

� Copy exported physical volume continues to be managed by the source TS7700

– Utilizes off site reclamation to free up previously exported tapes

� Customer performed recovery process– All copy exported data from a source TS7700 is recovered on an empty TS7700– Recovery options for test vs an actual disaster recovery

� Operation in a Grid Configuration – Executed on a specific TS7700– Logical volumes must have been copied to the TS7700 to be exported– Recovery is to a standalone TS7700

Tape Volume Cache Management – TS7740

� Designed to minimize job processing delays– Maximize cache hits

� Two options - Preference Group 1 or 0– Selectable by logical volume– Storage Class construct control– Preference Group 0 - prefer expedited removal from cache– Preference Group 1 - prefer to retain in cache

� Defined by Storage Class– Management Interface Web Interface

� Assignment options– Dynamic assignment by SMS– Fully Backward compatible with IART attribute (Initial Access Response Time provided by SMS

Storage Class Construct) – Static assignment through Management Interface Web Interface– System default

Tape Volume Cache Management –TS7740 (continued)

� The illustration below assumes 80 % of volumes created can be identified to the ACS

routines as infrequently accessed


Volume Pooling – TS7740

� Groups logical volumes on pools of 3592 tape cartridges

� Supports up to 32 physical pools– Media type control / intermix– Borrow / return from common scratch pool– Independent reclamation thresholds and policies– Reclaim to same / alternate pool

� Pool management– Move physical volumes from pool to pool– Move logical volumes from pool to pool

� Supported on both standalone and Grid attached TS7700

� Defined by Storage Group in Library Manager panels or TS7700 GUI


3592 Cartridge Selection Considerations – TS7740

� Use 3592 JB cartridges– 1.6TB capacity using TS1140 in native E07 mode– 1TB capacity using TS1130 in native E06 mode– Used in combination with TS1140 E06 Copy Export format for TS1130 based recovery

� Use 3592 JC cartridges– For very large amounts of data– 4TB capacity using TS1140 in native E07 mode– Used for copy export pools where recovery machine also supports TS1140

� Use 3592 JK cartridges– 500 GB capacity using TS1140 in native E07 mode

� Use 3592 JJ cartridges (128GB capacity1) – Where retrieval response time of individual data sets is critical

• Recall of migrated data sets– When recovery time for multiple datasets is critical

• Recovering 600GB of data from six 128GB cartridges simultaneously is faster than recovering from two 640GB cartridges

– Only with TS1130 and TS1120 tape drives– 3592 JJ read-only on TS1140 tape drive*

* Statements of IBM future plans and directions are provided for information purposes only. Plans and direction are subject to change without notice. Planned availability:

PGA1 code December 2011.


� Use 3592 JA cartridges (640GB capacity1) – Where retrieval response time is (usually) not critical

• Full Volume Dumps• Tape transaction logs (MI/MO)• HSM ABARS• HSM Recycle target

– Only with TS1130 and TS1120 tape drives.– 3592 JA read-only on TS1140 tape drive*

� Intermix of JA and JB cartridges – Can be assigned to a specific pool or added as a common scratch pool– May be borrowed/returned– Only with TS1130 and TS1120 tape drives– 3592 JA read-only on TS1140 tape drive*

� Intermix of JB and JC cartridges– Only when using TS1140 tape drive.– JB media leveraged in Copy Export pools when the recovery machine uses TS1130 drives.

� Use advanced policy management to create transparent backup copies– Enables automatic recovery in the event of a media error

3592 Cartridge Selection Considerations – TS7740

* Statements of IBM future plans and directions are provided for information purposes only. Plans and direction are subject to change without notice. Planned availability:

PGA1 code December 2011.


TS1140/TS1130/TS1120 Encryption Support – TS7740

� Requirements:– All TS1140, TS1130 or TS1120 tape drives must be encryption capable– TS1140, TS1130 or TS1120 tape drives must be enabled to run in native format mode – FC 9900 must be ordered

� One or more of the 32 physical pools can be enabled for encryption

� Out-of-band key management interface accessed via Ethernet interface that

connects the TS7740 to the network – Request for encryption key is directed to I/P address of primary key manager,

responses are passed through the TS7740 to the drive – To read a logical volume from a physical volume in an encryption enabled pool, the

TS7740 uses the key management interface to de-encrypt the data


Logical WORM Support

� Support for compliant logical worm (LWORM) tape volumes through TS7700

software emulation – Host will view the TS7700 as a logical worm library– Minor host software changes will exploit and assist in managing logical WORM volumes

� Previously written volumes cannot be upgraded to logical WORM volumes – Must read the contents and rewrite them to a new logical volume that has been bound as

a logical worm volume

� All clusters in a Grid must be at R1.6 for LWORM support


FICON Channel Failure Recovery

� Historically tape I/O was relative to the last completed command– As a result the host cannot just "redrive" a failed I/O operation– The location will vary depending on the last successful I/O command – The only way to recover was to append and perform a step or job restart – This tape architecture applies to ALL tape products

� FICON capable processors support Tape Positional Retry Architecture– FICON is not required, but an IOS firmware update may be required– The IOS maintains block ID of last successful I/O command in the I/O chain– If a I/O command failure occurs

• IOS attempts to reset the failed path or uses an alternate path• Clear any pending tape drive status• Repositions the tape to the prior known good position• Restart command chain the failure occurred in at the right point


VTS Migration


Supported Migrations

� B10 or B20 VTS/TS3500 tape library (3584) to TS7700/TS3500 tape library

� PtP VTS with each VTS attached to different TS3500 tape libraries to two Grid attached TS7700s attaching to the TS3500s

� Two standalone VTSs with each VTS attached to the same TS3500 tape library to a single TS7700 attached to the same TS3500

� VTS attached to a TS3500 tape library migrates to a TS7700 attached to a different TS3500 Tape Library

� Two standalone VTSs with each VTS attached to a different TS3500 tape library to a single TS7700 attached to a TS3500 tape library (the TS7700's TS3500 Tape Library may be the same as one of the VTS's TS3500 tape library, or it may be different)


Migration Considerations

� Every migration requires the VTS to use only 3592 J1A, TS1140, TS1130 or TS1120

backend tape drives and the VTS data must reside on 3592 media

� Although VTS allows the use of either 2-Gbps or 4-Gbps fibre channel switches to connect

to the backend tape drives, the TS7700 supports 4-Gbps and 8-Gbps switches
