Agenda

•Presenters Introduction

– Ros Schulman; Director of Field Integration

– Koichiro Nakajima; Product Manager

Today’s session will focus on Data Replication Management and Monitoring

1- Mainframe environments

2- Open Systems

3- Q&A

5

Mainframe Replication Refresher

• Hitachi - IBM Compatibility

– Hitachi Storage is plug-compatible with IBM® z/OS®

– Hitachi Storage Controllers respond as IBM 2105 Storage Controllers

– IBM PPRC Compatibility

• PPRC Commands are accepted by Hitachi storage controllers

• Supported for True Copy Sync and Async, and ShadowImage

• PPRC does not support Hitachi Universal Replicator

• PPRC operates on individual replication pairs

• PPRC (Point-to-Point Remote Copy) – what is it?

– Available on all supported z/OS releases

– Hardware solution to the problem of accurate and rapid disaster recovery

– IBM PPRC provides Synchronous and asynchronous data transfer

• Hitachi Business Continuity Manager provides added value over the standard replication management facilities provided by IBM PPRC

– Reduce Complexity

– Provide Enhanced Control and Visibility

– Simplify Management

– Reduce Cost

6

Hitachi Business Continuity Manager Software

• Host software that provides centralized and unified management of:

– Hitachi Universal Replicator software

– Hitachi TrueCopy® software

– Hitachi ShadowImage® software

– Lightning™ 9900V storage systems

– Universal Storage Platform™ family (including the Universal Storage Platform V)

• Single, consistent interface based on TSO/ISPF

• Real time access to critical thresholds for problem avoidance

• Auto discovery eliminates errors and accelerates deployment

• Automatic notification of key event completion provides greater control

7

Features

• Automatically discovers Hitachi storage systems and internal copy volumes

• Uses a single command to manage groups of copy volumes with common attributes

• Receives auto notification of key copy “state transitions”

– Suspend, duplex, simplex, timeouts

• Supports Advanced TrueCopy, ShadowImage and Universal Replicatorfeatures

• Real-time view of Universal Replicator and TrueCopy Asynchronous metrics

– Sidefile/Journal volume threshold percent, write-pending rate, link

transmission rate, offload timer, etc.

• Standard REXX scripting to customize and automate

• Integration with HiCommand® Replication Monitor

8

Business Continuity Manager Operations—Simple, Automated, Menu driven

• Set system defaults

• Discover storage systems

• Discover devices within storage systems

• Add copy group

• Define copy group attributes

• Add copy pairs to copy groups

• Manage copy groups

• Monitor group status

• Automate REXX scripts

9

Supports Advanced TrueCopy and ShadowImage Features

• TrueCopy reverse resynchronization – Enables planned outage and disaster recovery automation

• TrueCopy synchronous consistency groups – Enable rapid and reliable large database recovery

• TrueCopy “Freeze - Run” function– Reduces copy-cycle times for Three Data Center Copy

• Extended Remote Control– Manage Universal Replicator, TrueCopy and ShadowImage configurations

at a remote site that is not directly connected to the primary site

• Remote ShadowImage controls– Simplifies Three Data Center Copy operations

10

Only User Interface of Universal Replicator

• Universal Replicator implements Hitachi unique methodology of remote replication (Journaling and pull) to provide advanced feature/functions

• Advanced feature functions provided by combination of Universal Replicator and BCM

– 3 Data Centers (Cascaded or Multiple Target) configuration

– Delta Resync capability for enhanced resiliency

– 4x4 configuration to accommodate huge database Disaster Recoverability

• Universal Replicator’s uniqueness and advanced features are beyond the concept of Traditional PPRC

– ShadowImage and TrueCopy are PPRC compatible but Universal Replicator is NOT

11

Features Accommodate UR/TCA Metrics Monitoring and REXX Scripting

• Query Functions

– BCM

• Requires only one query command to obtain the status of a copy group which could contain potentially hundreds of pairs

– PPRC

• Must produce a CQUERY command with unformat for each pair.

A custom script is then needed to check status of all the pairs

• Many PPRC CQUERY commands would be needed to obtain this information

– This influences the performance of the data lines.

• Wait functions to support automation and scripting

– BCM

• YKWAIT is used to check for copy group state. This simplifies the automation of replication

– YKEWAIT “v1” GOTO(“v2”) TIMEOUT(“v3”)

– PPRC

• No equivalent

• Status must be checked manually on a pair by pair basis

• The must program their own “wait” functions

12

Use Case 1 – Ultimate Business Resiliency with Business Continuity Manager

• Type or script commands a number of times up to the number of pairs WITHOUT Business Continuity Manager

13

Use Case 1 – Ultimate Business Resiliency with Business Continuity Manager

• WITH Business Continuity Manager, a single command will do

14

Use Case 2 – Simple and Effective Management with Business Continuity Manager

• Configuration of TrueCopy WITHOUT Business Continuity Manager

• PPRC Interface– Type or script commands with numerous parameters

– Repeat the same commands with different parameters up to the number of pairs you create

CESTPAIR DEVN(X'"V1"') PRIM(X'"V2"' "V3" X'"V4"' X'"V5"') SEC(X'"V6"' "V7" X'"V8"' X'"V9"') , MODE(“CREATE")

• Configuration of TrueCopy WITH Business Continuity Manager

Step1: Discover Storage Devices

16



Step2: Create a Copy Group

17



Step3: Review volumes to be replicated

18



Step4: Make copy pairs!

19

Replication Monitor Integration

• Visualization on GUI and grasp the entire pair configuration (both Open and Mainframe) on the single pane of glass

• Leverage Replication Monitor Alert and E-mail/SNMP trap notification function for better monitoring experience

21

• Host software that provides centralized and unified visibility into the entire Hitachi replications

– Supports all Hitachi storage subsystems

– Supports all Hitachi storage replication features

– Supports open systems and mainframes (with BCM)

• Simple and Easy– Intuitive GUI interface with views as host, subsystems,

or pair configurations

– Discovers all Hitachi in-system and remote replication products

– Easy to navigate, manipulate reports, generate alerts

• Effective – Access to critical thresholds for problem avoidance

– Alert pair status changes or errors

– Ability to restart pairs in case of suspension or error condition

• Achieve higher SLA with less administrative Cost

HiCommand Replication Monitor

22

Use Case 1 – Simple and Effective Management with Replication Monitor

23

• Proactive Maintenance WITHOUT Replication Monitor

• Uncertain Data Protection quality – Difficult to monitor – Complex to validate the pairs status and relationship, multiple interfaces

– Difficult to determine what copy exist and where are they located


24

• Preventative Maintenance WITH Replication Monitor

• Grasp the entire configuration and status on a single tool with ease

• Discover and determine – What copies exist by how many?

– How are they related each others?

• Identify problem with indicator at once � no forgotten pairs any more

• Review critical thresholds– Recovery Point Objectives

– Health status


25

• Proactive Maintenance WITH Replication Monitor

Step 1: Receive Automatic notification of error (e-mail or SNMP trap)


26


Step 2: Identify corresponding Alert on Replication Monitor


27


Step 3: Identify problematic pair
