The IBM iCluster for i™ Portfolio• IBM iCluster for i (5733-ICL) V5R2

– Full featured System i HA– Remote journaling, sync checking, monitoring, alarms and alerts

and switchover– Auto-configuration command for ease of implementation– Scalable from SMB to Large Enterprises

• IBM iBalance for i– Chargeable feature of iCluster– Provides bi-directional HA for workload balancing on CBU Edition– Conflict detection and resolution built in

• IBM LPP – Install through RTSLICPGM– PTFS from PTF Central


What Happened to iCluster SMB?

• iCluster SMB (5733-ICS)– Introduced in 2007 to address small

and medium business market– Also addressed commoditization of HA

marketplace– Limited to 3 replication groups– Very low pricing

• Challenges:– Lengthened sales cycle due to pre-

qualification– Partners wanted to lead with SMB due

to price point– Customers wanted full functionality of

iCluster at SMB price

– Not aligned with PowerHA

clients

What Happened to iCluster SMB (contin.)


Building Blocks: IBM i Clustering Architecture

Yep! Are you still running?

ProgramRun in case of failure

What does Clustering Do?• Cluster management• Cluster Administrative Domain functions• Heart beating• Facilitates switchovers & failovers • Enables automated application restart and

cluster-enabled applications

What is Clustering?• Defines partitions and applications into

Nodes and Resources Groups (CRG)

• Creates “awareness” of one another for switchover and failover purposes

Production Node

Secondary Node

Howdy! Hello?


Tape

Synch Remote Journalling

Asynch repl.

Secondary (HA)(active)Production

Tertiary (DR)(active)

Key Benefits• Quick Switchover, near real-time for DB• Long distances are realistic• Secondary Copy of Data is available for use – e.g.

Web Query• Helps with Release Upgrades and PTFs• Offline backups with BRMS• Hardware flexibility• Use iCluster for i automation or i CRG• All i releases

Remote Journal

Remote Journal

iCluster for i: Logical Replication Software


What does it Look Like? Auto-configuration

• Why should the customer have to configure the product?• One command creates nodes, journals, sets product values, and creates replication groups and specifiers!• Done in 3 minutes!


Auto Configuration

• Select individual libraries to Primary or Secondary Group or

• PF13 to select everything to Primary Group


What’s it Look Like…JAVA GUI Administrator

Strengths 100% Java (quick response times) Real-Time event driven GUI Single point of administration Real-time status of nodes and groups Multiple-node support Run from a web browser!!

Monitoring via BlackBerry


GUI Performance Monitor

Strengths Quick visual indicator of switch readiness Operational capabilities Single point of administration Run from a web browser!!


Switching


Watching the switch take place…


Watching the switch take place…


Autonomics

• Integrity and readiness of backup via sync checks:

– Dataarea contents– IFS and physical file attributes– Object existence – Physical file contents via hash– Always active sync check

• Reduced administration

– Automatic re-sync of suspended objects

• Increased awareness of HA status:– EMAIL sent for suspended objects and

errors– Alarms and alerts when latency

thresholds exceeded – Monitor indication of refreshes, reorgs,

access path rebuilds files/members

TO: JoepgmrFROM: iCluster--------------------------*iC on system Toronto group Payr


Protecting other environments

• Windows, AIX and Linux replication through IBM Softek Replicator • Integrated switching

• Single command to switch Windows, AIX and Linux• Integration already provided and tested• Best of breed products for I/O based replication• Single point of contact and support


iCluster for i Pricing (From eConfig)

• iBalance is 25% premium on top of iCluster only• One yr maintenance is included• Standard System i SWMA charges for 1 & 3 yr renewals

• 1 yr SWMA is 20% of the list price• 3 yr SWMA is 20% X 3 X .90 i.e. 10% discount

iCluster for i 5.2 Enhancements • Complete integration with IBM i

– iCluster is now installed as a licensed program with licensing by standard IBM i license keys– fixes will be delivered as PTFs– one-stop for Support, with PMRs and APARs to track issues across both iCluster and IBM i.

• Usability– consolidation of multiple sync check types into easy-to-use groupings– consolidated, simplified reports– continuous Sync Check option which always runs as part of mirroring– checking attributes of non-journaled objects– better integration between Sync Check status and auto-recovery (suspension) status.

• Remote journaling performance and recoverability– faster startup when starting from manually set initialization points (set position, mark position).– enhanced recovery option for source system failure – force journal scrape

• Integrated clustering support– ability to configure and interoperate iCluster in pre-existing cluster configurations– easier control of recovery domain upon node failure.


Install of LPP


Adding License Keys

• Purchase licenses for every node on iCluster, except in LPAR Box

• Licenses are issued on a machine class basis

• If sent as a file, use ADDLICKEY and prompt PF4 to specify *LICKEYFILE

NOTE: Key specified here is a sample only – use keys specific to your HW


Upgrading from Previous Versions

• Save current iCluster product library DMCLUSTER into a savefile

• Install iCluster 5.2 into ICLUSTER product library

• DMIBMUPGR – mirroring starts from last apply position


PTFs from PTF Central

http://www.ibm.com/support/fixcentralhttp://www.ibm.com/support/fixcentral


Sync Check – Pre 5.2


New Consolidated Sync Check

Remember *OBJATTR does *LIST, *DTAARA, *BSF and *CHKJRN

Remember *FULL does *FILEATTR and *OBJATTR


New Always Active Sync Check

*CLUSTER Defaults are: *NO

200 ms*FULL


Force Remote Journal Scrape

• Problem… what happens if your primary system dies with remote journaling?

• Solution… issue DMSTRGRP with force scrape on backup!


External cluster visibility • DSPCLUINF command shows cluster nodes created in iCluster
