Storage Infrastructure Management

Managing storage infrastructure is key to ensure continuity of

businessEstablishing management processes and implementingappropriate tools are essential to meet service levelsVirtualization have changed the storage infrastructuremanagement paradigm

Monitoring is the most important aspect that forms the basis forstorage management

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


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


The goal of availability management is to ensure that the availabilityrequirements of all the components and services are constantly met.

Availability Management



Capacity Management

Example of capacity management activities are:Storage provisioning

Enforcing capacity quota for usersCapacity consumption trend analysis Technologies such as data deduplication, compression, and

virtual provisioning help to manage storage capacity efficiently


The goal of capacity management is to ensure adequate availability ofresources, based on their service level requirements.

Capacity Management



Performance Management

Key activities are:Fine tuning for performance enhancement

Identifying performance bottlenecks Example of performance management activities are:

Configuring multiple pathsChoosing appropriate RAID type and cache configuration


The goal of performance management is to ensure the optimal operationalefficiency of all components.

Performance Management



Security Management

It prevents unauthorized access and configuration of storageinfrastructure components

Examples of security management tasks are:Managing user accountsConfiguring zoning and LUN maskingConfiguring encryption services

Installing antivirus and firewallsAuditing of event logs


The goal of security management is to ensure confidentiality, integrity, andavailability of information.

Security Management



Reporting

Involves gathering information from various components or

processes and generating reports Commonly used reports are:

Capacity planning reportConfiguration and asset management reports

Performance reportChargeback report

Storage Infrastructure Management in VirtualizedEnvironment Virtualization technology has enabled managing storage

infrastructure efficientlyVirtualization at storage layerExample: virtual provisioning of LUN

Virtualization at network layerExample: VLAN and VSAN

Virtualization at compute layerExample: Virtual machines, memory virtualization

Storage Multitenancy

Enables multiple tenants to share the same storage resources

provided by a single landlord (resource provider) Security and service level assurance are key concerns in a

multitenant storage environment Secure storage multitenant environment should follow the four

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



34/45


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)


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.

Storage Tiering

LUN tieringMoves entire LUN fromone tier to anotherDoes not give effectivecost and performancebenefits

Sub-LUN tieringA LUN is broken down intosmaller segments andtiered at that levelProvides effective cost and

performance benefits
