IBM Systems

Architecture - Scalability� 100.000’s of Copy Sets and unlimited CSM sessions

−Enterprise customers can have hundreds of thousands of volumes to consider within their business resiliency strategy

−A single CSM session can manage replication for everything from a single open systems application, a z/OS sysplex or an entire datacenter

−To drive down Total Cost of Ownership (TCO), customers need the capability to build CSM sessions in ways that are meaningful to how they run their business.

IBM Systems

CSM Server Redundancy

� Standby CSM server for disaster recovery

� Different Operating System platform support (Linux/Windows/AIX/zOS)

− Active and Standby CSM Server may run on different OS platforms

� 100% consistent view across CSM servers of managed storage

� One-minute maximum to activate standby server and initiate recovery (RTO)

CSM GUI: Simple Setup

1. Add Storage Device

2. Setup Paths via Wizard (optional)

− Preferred option: Specify port pairings in a properties file which are used for all replication paths upon Start of Session

3. Create Session

4. Add Copy Sets

− Box to Box

− LSS to LSS

− Volume to Volume

− CSV Import

5. Issue Start!

Add Copy Set Wizard

IBM Systems

CSM – Command Line Interface (CSMCLI)� Installed with CSM on server – CSMCLI

� Separate CSMCLI installer packages available for remote CSMCLI installation on various

platforms

� May be used for additional automation

� Similar to DS8000 CLI

− Command structure (mk, ch, rm, ls, show)

− Help structure

− Exit Codes

� Three types of invocation

− Single-shot (Single CSMCLI command)• csmcli mksess –cptype fc mySession

− Script (Sequence of CSMCLI commands)• csmcli –script scriptfile

− Interactive (User CSMCLI session for multiple commands)• csmcli

� Password less scripts possible

− Password can be encrypted on client for password less access

IBM Systems

Built-In Safety Features

� User Roles

− Three access levels: Monitor, Operator, Administrator

� Site Awareness

− Protection against incorrectly reversing hardware

relationship at wrong location

� Volume Protection

− Exclude volumes from CSM sessions

� Command or Action visualization and Warning Message

− Visualize action to be performed and prompt for confirmation before a command or action is executed

IBM Systems

CSM – Continuous Role Pair Status and Progress� Role Pair status message

− E.g. Starting role_pair_name relationships on the hardware

� Provide an estimated time to complete for the action

− Calculated and updated based on remaining out of sync capacity change rates

� Progress reporting

− Progress bar displays copy progress value in percentage

− Progress details displays GiBs or tracks remaining

− Reporting at Role Pair level and at individual pair level

− Visualized in dynamic session images

IBM Systems

What is new in CSM 6.1.4?

� Support for standard to extent space-efficient (ESE) Peer-to-Peer Remote Copy (PPRC) relationships

� Single direction support in port pairing CSV file

� DSCLI shipped with Copy Services Manager on z/OS®

� Ability to Setup SNMP and email notifications through the CSM GUI

� Support for Ubuntu Operating System

� Support for FlashSystem™ A9000 and A9000R

� New event for SVC auto restart and auto restart failure

IBM Systems

Supported CSM on HMC feature without a license I/III

� Define DS8000 Storage Systems in CSM and view their volume configurations:

� View and Export DS8000 pokables and product switches

• This feature requires DS8880 R

8.1.1 or later

22

IBM Systems

Supported CSM on HMC feature without a license II/III� Configure DS8000 Heat Map Transfer:

• This feature does not require active replication Sessions in CSM. The HMT code auto-discovers

any replication between the enabled systems.

� View and manage PPRC paths of the connected systems

23

IBM Systems

Supported CSM on HMC feature without a license III/III

� CSM Support for Native LDAP Client on DS8000� Enabled in CSM by default

� No cost to DS8000 customer

� Software license acceptance (T&Cs) on initial CSM logon

� Replaces Spectrum Control (TPC) as the LDAP provider

� CSM provides the same interface as Spectrum Control (TPC)

� Same DS8000 LDAP steps except now CSM is the provider

� Resides on DS8000 HMC or wherever CSM is installed

� LDAP provider must be configured in CSM

� Both HMCs if dual HMCs

� CSM GUI support for LDAP setup is found in the Administration panel

� https://<hmc-ip>/CSM/

� csmadmin / passw0rd

CSM Value

� Common interface to manage heterogeneous IBM Storage System based copy services

� Easy and reliable user interface to setup large copy services configuration

� Simplify and automate complex replication tasks− Planned outage recovery

− Unplanned outage recovery

− Outage recovery testing

� Real world examples:

Task DSxxxx Command Line Interface Copy Services Manager

Set up Global Mirror 5 steps 1 command (START)

Global Mirror Recovery 4 steps 1 command (RECOVER)

Set up Metro Global Mirror 8-25 steps 1 command (START)

Make a practice copy 5 steps 1 command (FLASH)

Task SVC Command Line Interface Copy Services Manager

Set up Metro Mirror 4 steps 1 command (START)

Clean up a consistency group 3 steps 1 command (TERMINATE)

Make a practice copy 5 steps 1 command (FLASH)
