Comparing WWKNOW Colocation Sizes: Why the U Count Matters

When comparing WWKNOW colocation entries, look at the stated U count alongside the package name. The catalog snapshot verified on September 20, 2026 records a specific difference: the LA and Buffalo/Seattle entries label half racks as 22U and full racks as 44U, while the UK entries label them as 21U and 42U respectively.

That makes “half rack” or “full rack” an incomplete description for a purchase inquiry. Include the location label and the stated size when asking WWKNOW to confirm a configuration.

The table below compares the catalog names. These are recorded package labels, not confirmation of current availability or a complete technical specification.

The single-server and quarter-rack entries use the same size labels across these three groups. The half-rack and full-rack entries do not. For a comparison worksheet, preserve those differences rather than placing all half racks or all full racks into an identical-size column.

There is also a location detail worth clarifying. Four product names explicitly say “Buffalo/Seattle,” while their associated location category is named “Buffalo Colocation.” Treat the combined product label as something to clarify in your inquiry. It does not establish that you can choose either city, that both have capacity, or where a particular order would be placed.

A useful colocation inquiry should separate three questions: which catalog entry you mean, what equipment you want to place, and what the proposed service would include.

Start with the exact entry. For example, “Half Rack Colocation (21U) - UK” identifies a different recorded size from “Half Rack Colocation (22U) - LA.” Using the full name gives WWKNOW a concrete reference without assuming the packages are otherwise equivalent.

Next, prepare an equipment list. As a planning recommendation, record each device’s model, quantity, stated rack height, dimensions, weight, and documented power requirements. Include any additional equipment you intend to place with the servers. Ask WWKNOW to confirm the fit of the complete proposed installation; do not treat the package name alone as approval for that equipment.

Finally, request a written description of the service boundaries. The verified catalog records establish names and size labels, but they do not establish the following details:

• The exact facility and whether the requested configuration can be provisioned.
• Usable space, mounting arrangements, and equipment restrictions.
• Included power and the electrical requirements the installation must meet.
• Network connectivity, transfer allowances, and addressing arrangements.
• Equipment delivery, installation, access, and remote assistance procedures.
• Contract duration, billing terms, setup charges, and the total quoted cost.

Use these as questions to resolve, rather than features to assume are included. A matching rack-size label is not evidence that two entries have matching service terms.

For an initial inquiry, a concise request could read:

“Please confirm the exact facility and current provisioning options for Half Rack Colocation (21U) - UK. I can provide an equipment list with dimensions, rack heights, weight, and power requirements. Please confirm equipment fit, included power and connectivity, installation and access arrangements, and the complete commercial terms before I proceed.”

For a Buffalo/Seattle entry, add a direct request to identify the proposed city and facility.

Keep the catalog name, stated size, confirmed location, and written service scope together in your comparison. This gives you a clear basis for discussing the proposed installation with WWKNOW without turning a short package label into assumptions about what you will receive.
