Works seamlessly with existing applications – No Job Control Language (JCL) changes are required and works with your existing tape management system
Significantly improves performance – Reallocates all of the data to disk and uses smart I/O buffering, allowing potentially significant reductions in batch windows
Extends disaster recovery capabilities to the tape workload – Utilizes array-based replication process over IP to seamlessly move tapes offsite
Enhanced data protection with encryption and RSA Data Protection Manager – For data at rest or during transmission
Easily scales as the workload increases – Add throughput performance and storage capacity as needed © Copyright 2012 EMC Corporation.

VTEs will always include the RSA client
RSA Data Protection Manager requires a separately licensed RSA server Corporate network Access Control Point
Individual drives will be configured for encryption (as they are today)
When a new tape is written to a drive configured for encryption, a call to the RSA Data Protection Manager is made RSA Client with Software Encryption
The Data Protection Manager returns two keys: a clear key and an encryption key RSA Client with Software Encryption VTE RSA Client with Software Encryption
RSA client uses the encryption key to store the clear key on the volume

DLm replication starts based on RPO 2:40 AM Production Site Remote Site
Backup job starts – Backing up 100 GB dataset (will create a 30 GB tape)
Next DLm replication cycle starts based on RPO – Backup tape is being replicated – First 25 GB of tape are replicated
Backup job ends – “Rewind unload” command is sent to the DLm – DLm forces replication – Last 5 GB of the backup tape are replicated
Replication is complete – Return control to the mainframe host to finish the backup job © Copyright 2012 EMC Corporation. All rights reserved. 27 Testing the Disaster Recovery Environment Two ways to conduct disaster recovery testing from copy of production data Production Site Remote Site WAN/IP R/W Mainframe Bi-directional replication Disk Library for mainframe Read-only mounts • Disk arrays allow instant “read-only” copies • Confirm that tapes can be mounted and all required data can be accessed • No incremental storage capacity required R/O R/W Disk Library for mainframe Mainframe Snapshots • Disk arrays allow creation of “readwrite” snapshot • Confirm operation at the disaster recovery site • Some incremental storage capacity required Remote replication is uninterrupted © Copyright 2012 EMC Corporation. All rights reserved. 28 13 EMC Disk Library for Mainframe August 2012 How DLm6000 Maps to Mainframe Host
The mainframe host views Disk Library for mainframe as tape drives
Data for different use cases is directed to the appropriate storage type IBM z/OS mainframe
Drives are managed as mainframe tape libraries (MTLs) under System Managed Storage (SMS) EMC DLm6000 VNX storage Batch HSM Fixed content Data Domain storage Backup Archive
Tape administrator will map specific range of tape drives to a specific VTE
Each VTE can access any tape dataset in the library
Each tape VOLSER is kept on disk as a file – No wasted media © Copyright 2012 EMC Corporation. All rights reserved. 29 Disk Library for Mainframe Performance vs. Tape Physical tape Mount Seek Stage 5 Sec 5 Sec 3 Sec Batch processing Time to first byte: 13 seconds Disk Library for mainframe Job completion Provides…
Faster time to first byte – One second mount time on average Mount Batch processing at disk speed Job completion
Faster batch processing – Over 300 MB/s per VTE – Up to six VTEs Disk Library for mainframe © Copyright 2012 EMC Corporation. All rights reserved. 30 14 EMC Disk Library for Mainframe August 2012 Improved Response Time File name = Tape VOLSER
Fast locate provides additional performance benefits – Response times drop from 15–40 seconds to less than one second on average – Improves service level agreements – Immediate major benefit to fixed content applications such as: AWSTAPE ▪ IBM ImagePlus ▪ ASG-ViewDirect Index
When Disk Library for mainframe writes to tape, it builds an index for fast locate • Tape mark locations – Index is stored at the end of the volume’s disk file – Contains a pointer to: • 5 MB block boundaries ▪ Each tape mark location ▪ Each 5 MB block boundary Tape image on disk – On read, the VTE can go directly to any tape mark © Copyright 2012 EMC Corporation. All rights reserved. 31 No Single Point of Failure IBM mainframe EMC Disk Library for mainframe
All VTEs can see all tape volumes
If a VTE fails… – Job will fail with tape error (same as with regular tapes) – Tape volumes are still available through alternate VTE – VTE does not contain metadata
Disk drives are RAID 6 protected – 8 + 2 protection – (Global) Hot spare drives Parity Hot Spare Any VTE can access any tape volume in the library © Copyright 2012 EMC Corporation. All rights reserved. 32 15 EMC Disk Library for Mainframe August 2012 Tape Drive Sharing External software required for tape sharing across LPARs
Up to 2,048 emulated tape drives
Eliminates the need for automated tape device sharing software
VTE provides full multiple image support Disk Library for mainframe individual tapes across LPARs – Devices dynamically learn paths to attaching to up to 64 LPARs
Support for Autoswitch
Support for cascading directors © Copyright 2012 EMC Corporation. All rights reserved. 33 Reduce HSM CPU Cycles
Reduce/eliminate DFHSM ML1 – Move directly from L0 to ML2 – Save the mainframe CPU compression cycles – ML2 information is compressed and kept on disk in the DLm – Recalls at disk speed ML0 ML2 Disk Library for mainframe Production DASD
DFHSM recycle time optimized Virtual tape reclaimed on disk – DFHSM will continue to perform tape recycling ▪ Recycling at disk speed ▪ User-settable virtual cartridge size ▪ No contention for tape drives – Hours of savings potential © Copyright 2012 EMC Corporation.
