11 Why EMC Virtual Tape for Mainframe? Eliminates all issues related to traditional tape handling Eliminates manual intervention, physical movement of tape cartridges, robotic issues, and single points of failure 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 23 Technical Features The following optional slides show the technical detail of: WORM tape RSA Data Protection Manager Guaranteed replication Mapping the DLm to the mainframe High performance High availability HSM migration Disaster recovery vaulting and testing Management reporting Professional services Support 24 11

12 WORM Tape Enterprise Provides for retention periods per file Enables adherence to good business practices Tamper-proof clock Activity logging Compliance Meets SEC Rule 17a-4(f) compliance requirements Prevents file system deletions with locked files Hard default retention periods Data verification to validate committed content Retention periods cannot be modified File systems can only be deleted when retention period has expired Third-party compliance validation paper 25 RSA Key Management Corporate network RSA Client with Software Encryption RSA Client with Software Encryption RSA Client with Software Encryption RSA Key Server Access Control Point VTE VTEs will always include the RSA client RSA Data Protection Manager requires a separately licensed RSA server 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 The Data Protection Manager returns two keys: a clear key and an encryption key RSA client uses the encryption key to store the clear key on the volume Support for DLm6000 with VNX7500 storage only RSA Client with Software Encryption 26 12

13 Guaranteed Replication 2:00 AM 2:12 AM 2:30 AM 2:35 AM 2:40 AM DLm replication starts based on RPO 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 Production Site Remote Site 27 Testing the Disaster Recovery Environment Two ways to conduct disaster recovery testing from copy of production data Production Site Remote Site WAN/IP Mainframe R/W Disk Library for mainframe Bi-directional replication R/W R/O Disk Library for mainframe 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 Snapshots Disk arrays allow creation of readwrite snapshot Confirm operation at the disaster recovery site Some incremental storage capacity required Remote replication is uninterrupted 28 13

14 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 VNX storage Batch HSM Fixed content EMC DLm6000 Data Domain storage Backup Archive Drives are managed as mainframe tape libraries (MTLs) under System Managed Storage (SMS) 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 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 Job completion Disk Library for mainframe Mount Batch processing at disk speed Job completion Provides Faster time to first byte One second mount time on average Faster batch processing Over 300 MB/s per VTE Up to six VTEs Disk Library for mainframe 30 14

15 Improved Response Time File name = Tape VOLSER AWSTAPE Index Tape mark locations 5 MB block boundaries Tape image on disk Fast locate provides additional performance benefits Response times drop from seconds to less than one second on average Improves service level agreements Immediate major benefit to fixed content applications such as: IBM ImagePlus ASG-ViewDirect When Disk Library for mainframe writes to tape, it builds an index for fast locate Index is stored at the end of the volume s disk file Contains a pointer to: Each tape mark location Each 5 MB block boundary On read, the VTE can go directly to any tape mark 31 No Single Point of Failure IBM mainframe EMC Disk Library for mainframe Parity Hot Spare 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 protection (Global) Hot spare drives Any VTE can access any tape volume in the library 32 15
