What Is Raised Floor Cabling

In a standard raised floor cable setup. Horizontal and vertical bars are placed on the actual floor which creates a raised grid like structure. Inside this grid, flat panels are fixed and under this raised surface, all tupe of cabling is laid out. In some cases the chilled air is also pumped through this false flooring.

Raised floors is a good in terms of aesthetics as long as the complete cabling goes beneath the false raised floor and reaches the servers through the bottom cable sockets of Racks. So, it is mostly invisible from outside making the place look cleaner and neat. The other benefits of Raised Floor cabling are heat management and easy access to the hidden cables.

Cables in a raised floor setup should be run through the raceways ( cabling channels ). This helps protect them from interferences caused by power cables, security devices and fire suppression systems which are also generally laid down in the same raised floor area. Raceways also help in the distribution of cool air.

Almost all type of cabling such as structured network cabling, electrical cables, KVM wires and if required telephone wires, all go through this grid and pass through the bottom of each rack location power receptacles. Then these wires are passed into and connected through the Rack patch panels. The child air is pumped to the room through the placement of solid and perforated floor tiles.

And as discussed earlier using a raised floor setup one can make most of the patch cords and pathways invisible by keeping them away from the sight. This not only enhances the aesthetic value of the room but also makes the devices less prone to damage or getting manhandled.

But, one problem which we face most often with false flooring deployments is that, if your datacenter is scaling up rapidly and you have not planned the growth properly while deploying the datacenter, then there is a chance of the false flooring not taking the load of the equipments. But with a bit of planning such kind of issues can be tackled easily.

What Are The Different Type Of Cabling Techniques In Data Centers

We take a look at most commonly used cabling techniques in data enter and discuss their advantages as well as downsides.

There is a dire need for better cabling management in your datacenter. It’s not just about the network cables, but also the KVM, Power and all other sort of cables which you use in your datacenter. Cabling management, if not done properly, may lead to major operational complications such as cooling problems difficulty in identifying cables, performance loss and so on.

Cabling Pathways
As we all know datacenters have high density networks and equipment. And, high density equipment requires high density cabling systems. These high density cables are essentially Flat ribbon like cables which eat uo less area and can be easily stacked and structured. Higher density cabling components can help reduce the amount of floor space, rack space and associated costs.

Along with the high density cables, proper cabling raceways and pathways in the datacenter are a must. These pathways make sure that the cables are isolated from any other kind of interferences. So for example, a network cable and a power cable running parallel could cause loss of quality in the network stream due to interference. The raceway makes sure that the cables don;t just hang in between and get tangled.

Generally the pathways consist of a combination of accesses under a raised flooring system or overhead cable tray or both. Now we will have a look into the difference and benefits between the two approaches :

1> Raised Floor Cabling

2> Over Head Cabling.

What Are The Causes of Downtime in Data Centers

The biggest Culprit of downtime in a data center is probably human error, and a key reason for increased chances of human error is bad cabling.

What are some of the causes of downtime in a data center? Equipment failure, bad design, or human error? It’s obviously a combination of all but human error is probably the biggest culprit, and not without good reason. Let’s analyze each in more detail.

Equipment failure can be tackled by eliminating the main causes behind it, and by purchasing good quality equipment. Heat for instance, is the biggest enemy of most electronic equipment and IT is not exception. If the temperature of your servers, storage and other equipment is constantly rising then it’s going to degrade their performance, and eventually lead to system failure. This cause can easily be tackled by ensuring proper ventilation and air-conditioning. Apart from this most enterprises usually have a DR and BCP strategy in place to ensure minimum downtime even if there is equipment failure. Then of course, there are the usual technologies like RAID, automatic fail over systems, etc to ensure business continuity.

Next cause of downtime is poor design. If you’ve increased server density, but your data center does not have appropriate ventilation and air-conditioning for it, then you’re obviously headed for trouble. If you’ve not planned for sufficient power backup, then obviously, you won’t be able to add more equipment in your data center. What you end up doing in such cases is force fit, E.G keeping the rack doors open if they’re made of glass if you don’t have sufficient cooling or extending long cables between different racks to extend power and connectivity and so on.

The third cause, human error, is probably a result of all these adds, moves and changes in your data center. These changes could have been minimized if your data center was designed properly in the first place. Poor cabling desing can increase chances of human error considerably. If you have unnecessary cables dangling all over, then they’re likely to obstruct the cooling vents, thereby increasing the temperature in the data center. Unfortunately most data center administrators will look for alternatives to untangling the jungle of cables ( like keeping a fan in front of racks to keep them cool! ).

It’s only natural then, to have more human errors, and greater downtime subsequently. What’s needed is a good design in the first place, that’;s modular, standardized and one that gets the least affected due to changes.

This time, we’ll look at the cabling aspect of data centers. It’s extremely important to ensure a good cabling design to reduce chances of human error. So, whether you should go for cabling under a raised floor, or above the racks is one question. We’ll understand the pros and cons of each in future articles. Plus, we’ll look at the impact of improper cabling on a data center cling, which can be quite significant. Finally, we’ll also look at some equipment you can use to ensure proper cabling in the data center.

Virtualization is only half the battle for efficiency

InfraStruXureVirtualization is here to stay:

And it’s no wonder – it saves space and energy while letting you maximize your IT resources. But smaller footprints can come at a cost. Virtualized servers even at 50% capacity, require special attention to cooling, no matter their size or their location.

1. Heat : Server consolidation creates higher densities – and higher heat – per rack, risking downtime and failure.

2. Inefficiency : Perimeter cooling can’t reach heat deep in the racks. And over cooling is expensive and ineffective.

3. Power : Events Virtual loads move constantly, making it hard to predict available power and cooling, risking damage to your network.

The right-sized way to virtualize:

With the new High Density-Ready InfraStruXure architecture, you can take of the density by cooling the virtualized high-density row controlling power at the rack-level, and managing the system with advanced software and simulation. Though virtualizing saves energy, true efficiency also depends on the relative efficiencies of power, cooling, and server. Right-sizing one and not the others leaves efficiency savings on the table. To right-size, depend on the efficient, modular high Density-Ready InfraStruXure and neutralize heat at the source. Equipment will be safer and more efficient running closer to 100% capacity.

Don’t agonize, virtualize:

What are you waiting for? With High Density-Ready InfroStruXure architecture anyone can virtualize… anytime, anywhere. Just drop it and you are ready to go.

Principles of InfraStruXure High Density-Ready Architecture…

1> Rack enclosures that are high Density-Ready

2> Metered PDUs at the rack level

3> Temperature monitoring in the racks

4> Centralized monitoring software

5> Operations software with predictive capacity management

6> Efficient InRow cooling technology

7> UPS power that is flexible and scalable
