Data Storage Management

This process aims to assure optimal use of storage resources and reduce long-term storage-unit cost by improving performance through policies for availability, location, and versioning; keeping enough (but not too much) storage available on the floor and providing backup/recovery operations for critical data; and by data-set placement and compaction.

Tasks

Skills

Test/verify backup/restore versions

Maintain access and integrity of all corporate data on disk/DASD

Deploy compression/compaction utilities

Best Practices

Metrics

A validated tested backup/recovery system is in place

A consolidated storage management architecture that is completely cross-platform

Up-to-date backup and recovery plans for which all applications have been prioritized based on business-driven recovery requirements, including a list of what should be recovered and how long it should take

Ongoing, regularly scheduled performance management/optimization plan that includes determining which databases should be reorganized next, which volumes should be compressed/compacted next, and figuring the maximum utilization that also minimizes the risk of application failures due to space allocation

Time to restore/recover/backup

Year-to-year improvements in:

– Utilization

– Cost/GB

– Staffing/unit capacity (staffing/terabyte)

– Mean-time-between-failures: How many applications were affected how often, and for how long?

Process Integration

Futures

Tape management

Point-in-time replication deployed across enterprise to eliminate the need for batch and preventative maintenance windows

Storage technology improvements, including:

– Storage area networks

– Network attached storage

– Media commoditization lowering the price of storage devices

– Intelligent storage controllers and managers who understand characteristics of data and its usage, and automate decisions about where data is stored
