AFA (All Flash Storage ) Battle Field
- Controller Replacement
- Hot vs Cold Data
- SSD will be the only type of disk – This is a myth perpetuated by the All Storage guys and also NetApp. This is just a oppunion, has it happend yet, of couse not, so if you are a buyer that buys current technology for future benfits.. Can i have your job.

- We want to virtualize our workforce
- We have acquisitions planned that will require consolidation
- 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:
- 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?
- 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

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.
- One laptop with the SAN Monitoring & Analysis Software
- SAN Monitoring and/or Analysis Appliances
- Fibre TAP – Use of TAPs (Traffic Access Points)
SAN Health Check: A Step by Step Guide
- Client meeting to review the SAN infrastructure and perceived SAN issues
- Determine probe/tap placement and the number of probes
- TAP’s Installation
- Deploy SAN Monitoring Appliance
- 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.
- Generate initial report using initial statistics
- Provide necessary product training for end users (if necessary)
- Return to client after agreed period (up to 30 days)
- Evaluate collected statistics for any important trends or issues
- Generate custom baseline report using the collected statistics.
- 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.
