WEBTECH EDUCATIONAL SERIES

Storage Analytics

Attend this WebTech session to learn how to leverage storage analytics to

transform your storage infrastructure into a business enabler. Storage analytics

help you to manage your storage environment beyond the operational view to a

business-centric view where storage resources can become strategic assets to

drive storage service level management for business applications.

Attend this WebTech to learn

• Tips and tricks to streamline storage performance monitoring across your

Hitachi environment

• Establish storage service level management by defining and enforcing

performance and capacity objectives for key business applications

• Create storage service level management reports that satisfy the needs of

multiple IT stakeholders (i.e., CIO, architect, administrator)

STORAGE ANALYTICS

Enable customers to transform visualizing a data center from an operational view to more strategic and business-centric view

where elements are measured, correlated, trended and

strategized.

Which applications miss their SLAs?

Which applications are at risk?

HITACHI TUNING MANAGER: TOP PERFORMANCE TIPS

Look at longer historical trend first

‒ Identify troubled spots by looking at longer period of trend (for example, 7 days of hourly data, 24 hours of minute data)

Focus on trouble area with finer granularity

‒ After identifying trouble areas, zoom into those time periods with finer granularity (minute level)

For response time-centric applications such as online transaction processing

‒ You want low utilization to ensure CPU cycle availability

‒ You want low Q-depth to ensure no wait time

For throughput-centric application such as backups

‒ You want high utilization to ensure maximum throughput

‒ You want high Q-depth to let CPU manage queues smarter

HITACHI TUNING MANAGER TOP PERFORMANCE TIPS

Workflow from inside to outside

‒ Start at the I/O response time for the server or device reporting the problem

‒ In case the value differs significantly from the base value, investigate

High cache write pending percentage causing inflow control

High front-end processor (CHA) or MP (VSP) utilization causing port congestion

High back-end processor (DKA) or MP (VSP) utilization causing delays in reading from or writing to disk

High parity group utilization causing delays in reading from or writing to disk in that parity group

SERVICE LEVEL COMPLIANCE

Monitor service level objectives (SLO) for applications

‒ SLO is a measurement of performance for a group of storage volumes

‒ HCmD constantly monitors the mission-critical applications against their SLO and alerts users if it goes out of compliance

‒ HCmD provides dashboard summary of the current SLO violation and as well as its history for mission-critical application.

Investigate service level violations

‒ Global dashboard for near real-time monitoring of application SLO status

‒ Drill down to SLO investigation unit to help quickly identify potential causes of SLO violation

Realize application service level objectives

– Average storage response time

‒ Total IOPS

MONITOR SERVICE LEVEL OBJECTIVES

Support for service level objectives

‒ Application SLOs

‒ Storage response time

‒ Total IOPS

‒ Storage system and host SLO

‒ Cache write pending percentage

‒ DP pool overprovisioning ratio

‒ DP pool risk ratio

‒ DP pool used percentage

‒ Host file system used percentage

‒ Parity group busy percentage

‒ Port busy percentage

PINPOINT VOLUME UTILIZATION REPORTING

Scenario

1. Pool 4 and 16 on my VSP are

running my mission-critical

workload. I want to keep a

close eye on these pools and

the hot volumes in it to make

sure nothing gets overly busy

2. I want to save this report so I

can quickly get to it again and

again

3. I want to generate this report

from the CLI from time to time

because I prefer the command

prompt and I can do further

analysis with the CSV output
