Abstract

SRM and SAN Management: Reducing Management Costs and ComplexityThis session will illustrate the end user benefits of leveraging an SRM solution for effective, efficient and centralized management of everyday operational tasks as well as strategic initiatives. This tutorial will also illustrate the end user benefits being realized through the adoption of industry standards.

Agenda





Storage Infrastructure Challenges

Source: ESG Research – Based on ESG survey of 165 storage professionals


Additional IT Directives

Reduce capital expensesManage more with same number of peopleOptimize utilization of existing assetsFaster trouble shootingReduce the number of point products


SRM: The Great Enabler

Assists Daily OperationsAutomates discovery, monitoring, reporting, policy actionsReduces repetitive, manual administrationMoves admin from reactive to proactive management

Enables Strategic IT InitiativesProvides planning information and decision supportAccelerates project timelines and reduces costsReporting/tracking communicates project success


SRM Use CaseAutomated Discovery and Topology Mapping

Source: ESG, The Quantified Benefits of Storage Resource Management Software, 12/06

Tool Steps Comments Elapsed Time

Oracle DBA Studio

Launch DBA Studio Enterprise Manager. Select a database to manage. Launch the table space utilization view. Record table space to DB file mapping

DB admin login required

Command Line

Find the storage vendor and LUN (df –k and the Solaris format utility)

Root login required. Different for each operating system

HBA or O/S utility

Find WWN using LUN Different for each HBA

Storage GUI or CLI

Find the device using WWN and LUN. Record the RAID group and level. Record the hard drives in the RAID group and the drive configuration.

Different for each storage array

Manual

Switch GUI or CLI

View active zones Find the ingress port’s WWN. Find the egress port’s WWN. Record zone members and settings.

Different for each switch. Repeat for multi-switch SANs

SRM SolutionCapacity Planning and Utilization


SRM Use CaseAutomated Provisioning

Steps Tool Comments Elapsed Time

Location of unused capacity and/or add more drives Storage Console

Radically different user consoles for each vendor

Allocation of logical volumes Storage Console

Assignment of host addresses Storage Console

Use of LUN mask for security Storage Console

Multi-path Configuration Software and operating system

Available from multiple vendors with operating specific interfaces

Zoning Switch Console

Switch specific user interfaces. Zoning using WWN is tedious and can be error prone

HBA Configuration HBA Console Vendor and adaptor specific

Driver configuration BIOS or utility HBA and O/S specific

Server Recognizes new capacity O/S specific Very different procedures

between O/S

Manual

Application recognizes new capacity

Application specific

SRM SolutionAutomated Provisioning


SRM Use CaseApplication Performance Troubleshooting


Tool Steps Comments Elapsed Time

Trap collector

Initial traps are recorded. Hundreds of sympathetic alarms are generated equipment in the data path. All affected group leaders are notified. Wait to hear from applications group

Multiple tools may be required including HP OpenView, MicroMuse etc.

Meetings Group leaders and vendors gather to discuss problem

Finger pointing ensues

Visio Diagrams and Excel spreadsheets

Possibly outdated information is used to try to isolate problem

Tribal knowledge rules

Manual

Physical verification

Teams are dispersed through out the data center to check on their respective domains and isolate the problem

Time consuming, especially if multiple data centers are involved.

Approximately four hours – Extreme cases could days

Automated Database

module

Receive alarms and quickly indicate source of problem and application affected

One screen covers application through storage

Less than 5 minutes


SRM Benefits:Identify root causesor performance problemsImprove service levels

Real-time monitoring of storage

SMI-S in SRM Solutions

SMI-S compliant SRM solutions provide the following benefits:

Agent less management of Windows infrastructureNormalized management for all storage systems, switches and hostsDevice support added quickly, without “shims” or “translators” to proprietary interfaces CIM-standard database schema, instead of a proprietary data model, results in faster administrator ramp-up and less risk of vendor lock-in.


Capacity ManagementTotal capacity, total used, total available, unmounted volume, and percentage used summary statisticsVolume name, partition type (FAT, NTFS, etc.), total capacity, total used, available, and percentage used

Agenda





Lessons Learned

Management support and endorsement at the executive level plays a crucial role

In successful deploymentsIn enabling the savingsCritical to get all domain experts on-board

Storage admins, DBAs, system admins, Exchange admins

Move from a culture of provisioning to a culture of managementDriving up utilization requires performance managementUse SRM to create baseline for IT initiatives

Use reports to communicate success of IT initiativesSMI-S compliance reduces risk and increase choicesThe tools are available today - pick one and get started
