Aligning Storage Management Tools with Operational Processes Stephen Foskett GlassHouse Technologies
Introduction • The wide array of storage management tools have overlapping features, confusing names • Make sense of it by looking at storage management from a different perspective - what tasks do I need to perform? How will this product help me? • I will present a matrix of management tasks and technologies
Confusing Terms • There are no standard category names: • Storage Resource Management (SRM) usually analyzes host storage contents (number, type, attributes of files) but not always • Different Storage Management Suites have different functions
Overlaps and Gaps • Many “suites” do not offer SRM functionality. • 114 storage management packages! • >12 offer accounting, device management, SAN management. • <5 offer SAN design, process management, asset management. • None offers configuration management.
Package-Based Approach • Software packages are purchased arbitrarily: • Sales rep’s suggestions • Media coverage • Advertising • Hit or miss coverage of business needs
A Different Perspective • Select tools that fill your needs: • Understand the tasks to be performed • Determine which tasks require software • Prioritize requirements • Match required functionality to available products • Select a few products for maximum coverage
Storage Management Tasks • Types of tasks: • Engineering – Making things work • Operations – Watching things work • Management – Control • Analysis – Validation Process Task Policy Tool
A Storage Management Lifecycle • 4 phases - 67 discrete tasks in total
Storage Software Framework • Basic functional categories for storage management software • Each product has varying levels of coverage in different categories
Software Categories • Accounting • Measures the use of storage resources • Allows reporting and chargeback • Application Management • Integrates application-specific functions • Some limited to usage visibility, others integrate backup or replication • Asset Management • Records hardware deployment and usage information
Software Categories (continued) • Capacity Planning • Metrics, forecasts future usage, recommends upgrades • Configuration Management • Records configuration of devices • Automated change control for the architecture • Device Management • Manages end devices (storage arrays) • Information Lifecycle Management • Migrates data over time • Some (HSM) move data, others measure requirements
Software Categories (continued) • Performance Management • Measures performance of components, including devices and interconnects • Provisioning • Automates presentation of storage to hosts • SAN Design • Automates the design of SANs • SAN Management • Manages the interconnection of devices
Selecting Storage Management Software • Look for software offering just what you need • Minimize number of tools: • Lack of integration options • Complexity = Confusion • Look beyond “suites”
Final Thoughts on Storage Management Software • More and more hardware supporting SMI-S • More software using standard database back-ends • Often limited configurability – reporting, cost accounting • Some can read but not write to certain hardware
