What Are Our Clients Saying?

60% of our clients are looking to improve availability

Nearly 50% want to make significant security improvements

Over 25% want to implement high availability clusters


3

Macro Trends

Tape DR HA FT

Large Enterprise clients driving recovery timeSmaller client primarily focus on recovery point


4

Forces Driving HA/DR Growth Rate

Business Resiliency Requirements are becoming increasingly aggressiveo RTO and RPO expectations are approaching zero over time

New technologies enable greater flexibility for deploying resiliency in-houseo Hardware clustering exploits storage based resiliency

Large enterprise clients are moving to SAN based storageo PowerHA exploits and manages the IBM DS8000

It’s become a lot cheaper to build in-house HA/DR solutionso It’s easier to justify and get funding

SMB clients are moving up beyond tape (compliance driven)o Continuous data recoverability is rapidly becoming the norm

Firms are shifting from shared to dedicated recovery solutionso Outsourcing operations are based upon a shared model


5

CIO Pain Points With Business Continuity

Estes Express Lines uses Global Mirror and FlashCopy with PowerHA (copy services tool kit) for DR and automatic data back up. Thousands of employees use the systems 24x7 without disruption. Requires minimal day to maintenance and no expensive third-party software or outsourcing for back up recovery operations.

Metro implemented IBM DS8300s and Metro Mirror -- reduced storage costs, cut DR role swap time by two thirds, and enabled new business projects to be implemented faster, with testing on full copies

Cutting Storage Costs and Improving Business Resilience

Gameco implemented PowerHA and reducing downtime by over 90% with a consolidated single-vendor, environment for simplified administration

IBM i Data Resiliency Characteristics

iCluster (software replication) Approach o Application level deployment: logical replicationo Based upon IBM i journaling technologyo Characterized by asynchronous data replicationo Best fit for geographic dispersion & data recovery scenarioso Can be adapted to data center & role swap operations

PowerHA Approacho Geographic mirroring or DS8000 based mirroringo Synchronous replication for all IASP data (low maintenance)o Cluster Admin Domain for *SYSBAS datao Best fit for data center/metro “campus” deployment & role swap operationso Remote DR operations using Global Mirroring


22

Operational Challenges For High Availability

Data Synchronization o Ensures primary and secondary data are identical

Operationso Identify primary & secondary resources (data, IP address etc)o Insure application and data coherency

Can we switch now ?


23

IASP Solution Deployment

Over 800 IASP solutions have been deployedo 500 partitions in DS8000 deploymentso Pre enabled commercial applications are ready to go

Typical characteristicso Nearly all objects types used by an application will go into an IASPo Qsys objects are synchronized by Cluster Admin Domaino Objects that won’t go into an IASP might cause some application change o Test before going live

Power HA for i Business Resiliency ChoicesFeatures, Benefits and Considerations

Feature Benefit Products Considerations

Storage-Based Replication of all data written to disk Virtually unlimited geographic distance when using asynchronous Generally implemented for DR and HA (synchronous) Can be cluster controlled Synchronous (Metro Mirror only) or asynchronous network transmission (Global Mirror only) No manual management of replicated objects required FlashCopy means second copy of data can be used for fast backups, development, testing, etc. Order of changes is preserved via DS8000 and Metro Mirror Resolution of out of synch conditions (objects or data) is under control of DS8000

IBM Metro Mirror IBM Global MirrorIBM FlashCopy® Can be used alone or with IASPs & ToolkitNote: used with IBM TotalStorage® DS8000

Network Bandwidth (all data and objects are replicated to second system) Only supported via external SAN storage No concurrent access to second copy of data IF not using IASPs, system IPL required for switching to backup copy Additional disk for Consistency Groups (Global Mirror only)

Operating System-Based

Page replication controlled by operating system Ordering of changes is preserved by the operating system No manual management of replicated objects required Synchronous network data transmission Is cluster controlled Supports external or internal storage Only vary on of IASP is required for switching to backup system Resolution of out of synch conditions (objects or data) is under control of IBM i Generally implemented for HA

Independent Auxiliary Storage Pools (IASP)Cross Site Mirroring (XSM)High Availability Solutions Manager (HASM) (implemented with XSM and IASP) (V6R1 only)

Network Bandwidth (all data and objects in an IASP are replicated to the second system) Distance limitations No concurrent access to second copy of data Prior to V5R4 no source side tracking Requires IASP implementation

Logical Replication

Selective data/object replication may reduce network overhead Virtually unlimited geographic distance Concurrent access to second data copy (for backups, read only access, etc.) No special hardware configuration requirements Choice of synchronous or asynchronous network transmission of data (synchronous only with remote journaling) Generally implemented for DR and HA Can be cluster controlled Can be used alone or with other HA technology choices Supports external or internal storage No IPLs required for switching. When used in conjunction with IASP—vary on of IASP is required Ordering of changes controlled by HA ISV software interfaces
