Abstract

SRM and SAN Management: Reducing Management Costs and Complexity

Storage networks were introduced to ease issues with backup, improve access rates and availability as well as the efficiency of managing distributed storage. Storage networks also introduced many new layers of abstraction and network resources to manage, thereby replacing the direct application server to storage relationship.

This problem was amplified as storage administrators were forced to master multiple device managers, fabric managers, performance tools, etc., resulting in a soaring cost of training and administration. Today's SRM and SAN Management solutions allow administrators to become more efficient at managing resources and consequently service levels, and provide the automated discovery, monitoring, reporting and policy-based actions needed to proactively manage a complex, multi-

vendor storage network.

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 Use Case Application 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Possibly outdated information is used to try to isolate problem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

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.

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 initiatives
