Agenda • The Original 7 • Walking through the Abuse of Storage • Contrary Virtues • Techniques and Savings • Summary
The Original 7 • • Gluttony Anger Envy Greed l Lust l Pride l Sloth
Gluttony. . . or why can’t I keep it all • Inordinate desire to consume more than required • The sys admin who had 9 OS generations on disk • The user who kept every file he ever touched • My inbox • Solution: Strict life-cycle management
Anger…it’s all your fault • Manifested by an individual who ignores life’s positives and opts instead for fury • User complaining about response time • “What do you mean my data isn’t recoverable” • Solution: Managed Service Level Agreements
Envy…I deserve it all • Desire for another’s position/possession • Why does her work get priority • How come I’m here in the data center 24 x 7 • Solution: Automated policy management with exception handling
Greed…need it or not, its mine • Desire for material advantage • Every dot-com that’s come and gone • I want everything in my data warehouse • Take over my departmental system, but. . . • Solution: Enterprise-wide, consolidated IT
Lust…just give me the latest & greatest • Inordinate craving for the toys of life • Who gets the sleek new laptop • Why do the network gurus get the 10 Gbs links • Solution: Manage storage for business ROI, not overhead cost
Pride…I’d rather do it myself • Excessive belief in one's own abilities • • • The manual? , who needs directions ‘tar’ and ‘cpio’ are everything you need I ran the 1 st pre-beta on my block • Solution: Get rid of the “wild ducks”
Sloth…let the other guy do it • Avoiding physical or ethereal work • Keeping documentation current • Testing all those DR backups • I need 2 TB for that new app…tomorrow! • Solution: Treat IT, especially storage, as a business asset, with measurable, reportable ROI
The Contrary Virtues • • Denial Patience Kindness Sharing l Charity l Humility l Diligence
Typical Storage Admin Workloads • Mainframe 5 - 10 TB FTE – Really 1. 5 FTEs shop – DFSMS fully implemented • Consolidated open systems – 750 GB – 3 TB FTE – Well known dot-com 100 TB FTE • LAN based DAS Tip – 200 GB – 500 GB FTE – ~25% of LAN administrator
Policy-based, Exception Management • Information life-cycle – Pre-define end-of-life – Manage performance • hsm – Archive/delete Best Practice • Automate data integrity processing – Backups & Disaster Recovery – Build-in encryption standards – RAID may not be enough
Use Technology to Manage Technology • Networked storage – SAN & NAS support snapshot/remote copy – NDMP can use SAN hooks – SAN -> SAM Best Practice – Virtualization • SRM will become RSM – Real-time Storage Management – Application focused reporting – Automatic capacity provisioning 14
Summary • Storage is an enterprise resource • There are no silver bullets • Tools & technologies almost keep up • Reinforce the business value of storage
