Four Employee Behaviors That Can Kill Your Business
I found it important to clarify for employees what “deal-breaker” behavior was at my company. These are the things I insisted would not be tolerated and would lead to immediate or ultimate termination, depending on the nature of the infraction of these hard and fast rules. Here are the behaviors I would not tolerate:1. Gossip. Rumors can be incredibly disruptive to a company. A lack of information can get rumors started, and frank explanations can usually stop them. However, some employees thrive on the admiration of

Service Release Premium - Why You Should Never Trust Your Bank When Mortgage Refinancing
If you are considering mortgage refinancing with your Bank you should read this discussion before committing to a Bank loan. Banks charge Service Release Premium with their mortgage loans, a hidden fee that will cost you thousands of dollars in unnecessary interest. Here is what you need to know about Service Release Premium and how Banks overcharge for their mortgage loans.Service Release Premium is the markup Banks add to their mortgage interest rates to make a profit on the secondary market. Banks pool their mor

Improve Financial Health Through Bad Credit Debt Consolidation
People tend to fall in debts in these days of easy availability of finance and liberal use of credit cards and as a consequence are labeled as having bad credit. Primary concern of these people is to eliminate debts as early as possible. An effective and popular way of eliminating previous debts, bad credit debt consolidation makes available required finance at easy terms and conditions to pay off debts. Lenders provide loan for bad credit debt consolidation taking into account different financial backgrounds of borrowers. areas: the facility layout, chillers, and computer room air conditioning (CRAC) units.

Facility Layout
Servers generate heat as they run. This is generally blown out the back of the server by fans; cool air is taken in through vents at the front. Server racks and rows should be laid out to manage hot air coming from the servers and conditioned air going to their intakes by designating “hot rows,” which face the server fans, and “cold rows,” which face the intakes. Designated hot and cold rows keep air circulating in the best directions to keep servers from overheating.

Facility Design
There are two kinds of building design for colocation facilities: raised floor and solid floor. Raised floor was the preferred structure when servers were towers because the mesh flooring allowed air conditioned air to blow from the bottom directly across their intakes. However, since servers are stacked in racks, cold air must reach the tops of the racks to cool machines. Solid floor facilities are a better option. The facility should take into account the following:

• Solid floor designs must have mesh front and rear doors for th server cabinets to allow hot air to escape.
• For raised floor designs, cold air must have enough air pressure to force air to the top of the server cabinets. Ideally, special duct work will be in place to force the airflow upward.
• For raised floors, server cabinets should not have vents in the doors that would let cool air escape.

Chiller Systems
Chillers pipe water or water/glycol coolants through the CRAC units. Chiller systems include pumps, pipes, and the chillers themselves. The following points should be considered to make sure that the system is adequate to cool the facility:

• Sufficient capacity
• Backup units for the pumps and chillers which switch over automatically
• Regular maintenance

CRAC Units
CRAC units are massive, dedicated air conditioners which manage temperature and humidity. They have many parts and are complicated – meaning failures can be common. The CRAC units should be well maintained, but the most important thing is redundancy. Redundancy is determined by the overall capacity of the CRAC units; there should be enough units that even with a failure, the facility will still be adequately cooled. As with chillers, capacity for CRAC units is determined by tons per square foot.

Verify Capacity
Capacity is determined by the ratio of tons per square foot. To determine whether a system has sufficient capacity, divide the total tonnage of the units by the square footage of the building. If there are four 30-ton CRAC units in a 4,000 square foot facility, then the CRAC capacity is .030 tons per square foot (120 tons / 4,000 square feet). The ideal ratio of tons to square feet for the CRAC system is .030 ton/sq

This same formula is used for chiller systems, with the same ideal ratios.

It is important to look for a colocation facility that has Internet provider options and backup power systems. Equally important is a facility with the right design, chillers, and CRAC units to cool the server room. Keeping equipment from overheating will keep networks up and makes equipment last longer. Like Internet connections, network uptime, and power backups, cooling systems signify a quality colocation facility.
