Data Center World – Certified Vendor Neutral

Each presenter is required to certify that their presentation will be vendor-neutral.

As an attendee you have a right to enforce this policy of having no sales pitch within a session by alerting the speaker if you feel the session is not being presented in a vendor neutral fashion. If the issue continues to be a problem, please alert Data Center World staff after the session is complete.

The Question?

Average outage is 134 minutes

Average outage cost is $5,200 per minute

Enterprise level outage cost is $11,000 per minute

The Answer:

Availability

What Really Matters?

• Quality control process

• Focus is on availability

• Verify performance

• Verify redundancy

• Document

Mission Critical Commissioning

• Reliability is a measure of the probability that an item will perform its intended function for a specified time interval under stated conditions.

• Availability is the proportion of time a system is in a functioning condition.

Reliability vs. Availability

A piece of equipment can be available but not reliable.

For example, the equipment is down 6 minutes every hour. This translates into an availability of 90% but a reliability of less than 1 hour.

• Redundancy

• Test It
