Alerts
It is an integral part of monitoring
It keeps administrators informed on the status of componentsand processes
Monitoring tools enable administrators to assign differentseverity levels for different events
Classified as information, warning, and fatal alerts
Module 15: Managing the Storage Infrastructure 14
Type of alerts Description Example
Information Provide useful information Does not require administrator intervention
Creation of zone orLUN
Warning Require administrative attention FS becoming full Soft media errors
Fatal Require immediate attention Component failure Power failure

Availability Management
Key activity is to provision redundancy at all levels Example of availability management tasks are:
Installing two or more HBAs per serverInstalling multipathing softwareDeploying clustered serverConfiguring RAID
Deploying redundant fabricConfiguring data backup and replication
Module 15: Managing the Storage Infrastructure 17
The goal of availability management is to ensure that the availabilityrequirements of all the components and services are constantly met.

Storage Management Initiative (SMI)
SNIA has been engaged in an initiative to develop a common
storage management interface SNIA developed a specification called Storage Management
Initiative-Specification (SMI-S)It forms a normalized, abstracted model to which a storageinfrastructure components can be mappedEnables standardized and end-to-end control of resourcesSMI-S compliant products are easier and faster to deployEliminates the need for development of vendor-proprietarymanagement interfaces

Benefits of ILM
Provides lower total cost of ownership
By aligning the infrastructure and management costs withchanging value of information Provides simplified management
By automating the processes
Maintains complianceKnowledge of what data needs to be protected for what length oftime
Optimized utilization
By deploying storage tiering

Storage Tiering
Each tier has different levels of protection, performance, andcost
Efficient storage tiering requires defining tiering policies Storage tiering implementations are:
Manual storage tieringAutomated storage tiering
Data movement occurs between tiersWithin a storage array (Intra-array)Between storage arrays (Inter-array)
Module 15: Managing the Storage Infrastructure 34
It is a technique of establishing a hierarchy of storage types and identifyingthe candidate data to relocate to the appropriate storage type to meetservice level requirements at a minimal cost.
