  • What do you see as the greatest risks to your business?
  • How do you differentiate yourself from your competitors?
  • How do you see the data center supporting your competitive differentiation?
  • What plans do you have in place for business continuance? Have they been implemented?

LISTEN for:

  • We need to reduce TCO
  • We need to make the data center a profit center
  • Green initiatives are of great importance to our customers, too.
  • We want to expand our cloud services
  • We want to virtualize our workforce
  • We have acquisitions planned that will require consolidation

ACT/Do:

  • Research the company well: Dig into financials, read industry reports, subscribe to industry blogs and feeds
  • Build consensus at operational levels
  • Know competitor offerings
  • Prepare to describe how an end-to-end approach can reduce TCO and improve productivity.
  • Ask yourself: Why does my customer need or want it?
  • Know your competition.
  • Review available Cisco Capital options.

 For technology decision-makers:

ASK:

  • Tell me about how your data center has developed. Has that development posed challenges?
  • Are you moving to total virtualization?
  • What business strategies are you grappling with fulfilling now? Into the future?
  • How do you see the data center contributing to business growth?
  • How quickly can you roll out new apps?.
  • What issues are you experiencing around technical readiness, implementation, monitoring and optimization?
  • What technical issues keep you up at night?
  • Has your business continuance and data recovery plan been tested? Is it adequate to effectively deal with internal and external risks and threats?
  • How do you expect the Cisco data center solution to help you?
  • Are you planning to deploy new applications,
  • Do you have any plans for data center growth or changes? Or are you adding new branches or acquired companies to the data center load?
  • What is your biggest challenge in the data center today?

LISTEN:

  • We struggle with planning around product lifecycles
  • There are too many access points/policies that are difficult to manage effectively.
  • We need to have air-tight security
  • We need hardware and software support for our remote workers.
  • We’re not getting efficient utilization out of our existing infrastructure.

ACT/Do:

  • Describe planning around business lifecycles instead of product lifecycles
  • Use the three-level architectural selling model :
  • Identify Current State – technical and business
  • Define Target State
  • Create Transition Roadmap
  • Know what the competition is offering, and why

Policy

The following example policy can be used to configure a RULE for new and existing files.

RULE 'migdatfile' MIGRATE FROM POOL 'system' to pool 'sata' WHERE UPPER(name) like '%.DAT'
RULE 'datfiles' set POOL 'sata' WHERE UPPER(name) like '%.DAT'
RULE 'default' set POOL 'system'

Following command validates above Policy RULE

mmlsattr -L *dat

file name:            testfile1.dat
metadata replication: 2 max 2
data replication:     2 max 2
immutable:            no
flags:                illreplicated
storage pool name:    sata

SAN/Storage Health Check

SAN/Storage Health Check

Performance analysis is very much an art (not a science) and it’s sometimes difficult to pinpoint exact causes based on the mix of applications and workload on the array. It takes extensive amounts of experience and research to solve these bottlenecks.

Hardware

  1. One laptop with the SAN Monitoring & Analysis Software
  2. SAN Monitoring and/or Analysis Appliances
  3. Fibre TAP – Use of TAPs (Traffic Access Points)

SAN Health Check: A Step by Step Guide

  1. Client meeting to review the SAN infrastructure and perceived SAN issues
  2. Determine probe/tap placement and the number of probes
  3. TAP’s Installation
  4. Deploy SAN Monitoring Appliance
  5. Configure SAN Monitoring software
    This can be installed either in one of your servers or it will come in a ready configured laptop that we will be provided in order to collect the necessary statistics. This laptop will be connected directly to our SAN Monitoring equipment and it will not interfere with your network.
  6. Generate initial report using initial statistics
  7. Provide necessary product training for end users (if necessary)
  8. Return to client after agreed period (up to 30 days)
  9. Evaluate collected statistics for any important trends or issues
  10. Generate custom baseline report using the collected statistics.
  11. Generate a series of reports (see below) that characterize the “Health of the SAN” for the monitored environment. An Xgig Analyser may be installed in order to capture a trace if that is necessary.
  12. Appliances Removal

REPORT SAMPLE

  1. ABC Company

STANDARD REPORTS for:

  1. Baseline SAN Performance
  2. Combined SAN Summary Report
  3. Disk Performance Analysis
  4. SAN Capacity Summary
  5. SAN Latency Trend Analysis
  6. SAN Link Queue Depth
  7. SAN Max Latency Trend Analysis
  8. SAN Summary Report
  9. Client Custom Reports
  10. HCL Matrix (firmware, drivers, versions,etc)
  11. Heat Maps
  12. OS Optimization

Approach

  1. SoW
  2. Kick Off Meeting (Success Criteria)
  3. Data Collection
  4. Analysis (2 Reviews)
  5. Workshop Recommendation and Presentation
  6. Remediation
  7. Validation Report

  • Identify OSI Layer to Assess
  • HCL Matrix
    • OS Optimization
    • Multi-path Drivers and Configuration
    • Hardware Diagnostic
    • Hypervisor Diagnostic
    • Storage Diagnostic
    • Firmware Levels
    • Switch
    • Storage (Block Sizing)
    • Error Events Correlation
    • Support Cases with Vendors
  • Usage Trends
  • Review of original implementation objectives against current objectives.
  • Review of each inventory item within the SAN configuration with all mappings of volumes and channels examined.
  • Verification of application server configurations including detailed review of HBAs.
  • Work with storage/switch experts to verify the configuration, firmware, zoning and profiles in place and examination of cabling — note patch panels, fibre type (look for mixed MM types), long runs etc.
  • Documentation of the SAN components including SAN Diagrams, Hardware Matrix, and Site Planning Checklist review/update.
  • Review of vendor support matrices (Brocade, IBM, DataCore, etc.) to ensure compatibility.
  • Review of all reported problems that remain open or seem to be recurring since the original installation.
  • Review of your storage administration procedures related to the entire storage infrastructure.
  • Agreed time window for changes and agreed next steps with the objectives for the follow-on SAN improvements, if changes to the configuration are required.
  • Preparation of a summary report with recommendations for an optimal SANsymphony configuration.
  • Use a Fibre Channel Protocol analyzer
