Key Tips to a Successful Rack and Stack

 When it comes to succeeding in any profession, it is always important to understand the fundamentals of that particular field. In data center hardware implementation, the most basic concept is the physical placement of hardware inside a data center; or as IT professionals like to call it, the “rack and stack” of hardware into cabinets and racks. System3 Offers a Professional Service to Rack and Stack in India, but here are some useful strategies to consider for a rack and stack job if you want to do it on your own.

1. Know the brand of the hardware and the brand of the rack beforehand

This will give you a feel for what adjustments are needed for the racks and hardware rails. If you know both the hardware and the rack are made by the same manufacturer (ex. EMC, Dell, IBM, etc.), then your job will be easier because the hardware is made to fit nicely into its accompanying rack. In other words, virtually no adjustments will be made to the rails or rack.

2. Understand all power requirements before arriving on site

A key factor that delays many projects is power-related issues. In some instances, a client’s data center is not prepared with the necessary power for the given project. This can end up delaying a project by several days or weeks. However, with a little more preparation on the consulting side, this is an avoidable concern.

• Contact the Data Center a few days in advance of the on-site visit.

Make sure their facilities manager allocates the proper amount of power circuits if brand-new racks are installed.

• Confirm with the ISP for Circuit Delivery

You don’t want to be on-site without any Internet connectivity. Work with ISP’s closely to ensure that circuit delivery and last-mile patching is done before the equipment arrives on site.

• Know the type of PDU’s (Power Distribution Units) used in the data center

Some PDU’s have outlets for the “C13 to NEMA 5-15P” standard power cables while other PDU’s have outlets for the “C13 to C14” power cables. C13 to NEMA 5-15P power cables have a female end that plugs into the hardware device and a male end which has three prongs and plugs into the power outlet. The C13 to C14 power cables are similar except the male end has a hooded enclosure over the prongs. Order the Right Power Cords

• Organise for Onsite Arrival

Plan where the equipment will be unloaded, how will it be unloaded, and who will do this – do you need extra manpower? Where will the Equipment be prepared, how much storage space do you have? Who will move the Equipment from the store to the racks?

• Understand Data Center Layout

Is the rack space allocated sufficient, both for today and for your future growth? What happens when you need more racks – will they be adjacent, or in another aisle? Review sales order and hardware list to ensure enough rack space are available for all equipment (Both rack mount and non-rackmount).

3. Be prepared with the necessary tools and materials

One would have a tough time completing a rack and stack with their bare hands. Here are some tools & materials we recommend:

• Screwdriver drill and bit set

When racking and stacking many pieces of hardware, it can get very tiring to mount all screws with a standard screwdriver. A drill will save time and energy.

• Standard Phillips head and flat-head screwdrivers

The drill should be used the majority of the time, but standard screwdrivers are handy for awkward angles that arise from time to time.

• Scissors or box cutter

These are absolutely necessary for cutting through boxes, tape, and packing materials.

• Zip Ties or Velcro ties

Racking and stacking involve a large volume of cables. These ties are essential for cable management, cleanliness, and organization.

• Label Printer & Label Tapes

You will need to label everything, from cables to equipment.

• Spare Power Cords

Never a bad idea to have few at hand, if for nothing else some boxed material may have dead on-arrival power cords.

• Cage Nuts and Screws

While most of the rack rails today do not need these, you never know which equipment did not come with the right nut and screw set and will end up not getting mounted properly.

4. Safety first: always ask for assistance when needed

In many instances, the rack stack pop India engineer is left to complete the work independently. While this is certainly doable, there are times when it is just too difficult to lift a heavy piece of hardware above one’s head and line it up into a rack. Trying to handle an excessive load can lead to injury or damage to the expensive hardware. The best solution for this is asking someone for help or using a server lift machine.

5. Document your rack design and layout

Label all servers, IT equipment, and rack accessories. As you are labeling, remember to record all serial numbers. Having a complete inventory of all the equipment in the rack and continuously documenting changes will keep you better informed in the future.

6. Install the heaviest servers and equipment at the bottom of the rack

Maintaining the bulk of weight at the bottom of the rack will prevent it from tipping over in the future.

7. Label both ends of cables

Keep track of network connections precisely. Accurate port mapping and cable traceability will greatly help engineers and technicians with ongoing maintenance.

8. Use different colors of cables to distinguish different roles and functions

We like to use Blue and Red Powercords to differentiate between A and B Power Feeds, and Multiple colors of Networking Patch management Delhi cords to plan for Storage, Primary, and Secondary Network Connections

9. Tie off Cables in bundles per function

Using either plastic cable ties or Velcro. There is a disadvantage to using plastic cable ties as they must be cut to make any modifications. Velcro, on the other hand, can be unbound and rebound as needed to make adjustments without having to unbind the whole cable run.

10. Leave slack in the cables

Eight inches of slack is ideal, but you should leave no more than twelve inches of slack as this excess can become cumbersome.

11. Do not bundle power cables next to data cables

Bundling the different types of cables closely together causes electromagnetic interference.
