Application Integration


What is Host Software?


Simultaneous development efforts


NextGeneration Virtual Storage Meets Server Virtualization

� Benefits of VMware Virtual Infrastructure

– Maximum consolidation to reduce data center footprint

– Ease of use

– Increased resiliency

– Streamline deployment and configuration processes

– Automatic and dynamic load balancing (VMotion)

Why wouldn’t you want the same capabilities in your storage?


VMware - vStorage APIs

vStorage APIs deliver tight integration of advanced capabilities from

storage partners with the Virtual Datacenter OS from VMware.

vStorage APIs for array integration will enable customers to leverage

array-based capabilities, such as snapshots, provisioning, replication

and restore, directly with individual virtual machines in conjunction

with the clustering and pooling capabilities of VMwareInfrastructure.

What SRM Does

Automate DR failover and tests

� Playback of what wasprogrammed into VirtualCenter during setup

� Benefits

– Speed: recovery starts witha single click

– Simplicity: Most effort isin setup

– Reliability: This virtualrunbook is the same as isused for all tests


XIV SRA for VMware SRM

Make VC aware of XIV replication

� Setup: Discovers which VMs are

replicated by

– Querying XIV array for

replicated LUNs

– Matching replicated LUNs to

datastores and VM inventory

� Failover: Automates promotion

of LUNs at remote site

� Test: Automates LUN snapshot

creation/deletion for test

� Support:

– ESX 3.5, 4.0

– VSphere 4

– Sync and Async


Microsoft Cluster Server – Introduction

� Also known as Failover Clustering starting Windows 2008

� Provides high availability for Windows Server-based services and applications

� Two modes – local cluster and geographically dispersed cluster

� In Geo-Cluster, storage required to provide replication

– Synchronous replication often referred to as Metro-Cluster

� Windows 2008 added various quorum options other than single quorum disk

– Majority Set Nodes

– File Share Witness

XIV support of MSCS

� Employing the “Big Red Button” scheme

– Due to the danger of data loss on rolling disasters

� Failback support

� Support for Windows 2003, 2008, 2008 R2

� Support for Sync replication (ASync support coming soon)

� Includes configuration verification tool


SAP

� There are two aspects for storage system sizing: capacity and performance

� To estimate I/O profile and size storage for SAP environment:

– Quicksizer tool estimate I/O profiles for planned SAP installations

– Use actual IO/s performance measurements in existing installation

� Storage system are sized based on number of SAPS it can service:

– ERP (OLTP) 1 SAPS is equivalent to approx. 0.4 IO per sec

– BW/BI (OLAP) 1 SAPS is equivalent to approx. 0.6 IO per sec

� The service time performance constraints of a SAP ERP application:

– between 5 and 7 ms - expected

– between 10 and 15 ms - considered good

– above 20 ms - considered as performance bottleneck

– beyond of 30 ms - system does not behave as expected towards the users


Measured OLTP Performance

� OLTP Performance from single IBM Power 520

� No model but real performance (old HW, R2.0)

� Be aware that we used only four IF module! Best pracitce would be to use all six.


SAP OLTP Workload with XIV

� Typical Random OLTP Workload with 70/30/50 and 8kB Blocksize

� Guideline: XIV can handle up to 50.000 IOPS with < 15ms

Introducing Tivoli Storage FlashCopy Manager� You’ve heard of NetApp Snapshot™ and NetApp SnapManager®?

� IBM FlashCopy® and IBM Tivoli Storage FlashCopy Manager offer a compelling alternative solution for IBM and virtualized non-IBM storage environments.

FlashCopy � Create instant application copies for backup

or application testing

� Make better use of space with incremental

(only changed blocks) or space-efficient

(thin provisioned) snapshotsDS8000

FlashCopy Manager* � Integrated, instant copy for critical

applications

� Virtually eliminate backup windows

� Rapidly create clones for application testing

� View inventory of application copies and

instantly restore

� Optional TSM backup integration
