A Data Closet at the Edge
A subsidiary of a worldwide real estate management firm needed to consolidate colocation facilities with a goal to leverage Azure, increase network speeds, and create return on investment (ROI). However, there were still were some local on-site computing needs.
The original plan to address local on-site needs was a system of two Dell VRTX Hyper- converged server blades with 16 usable cores even if one of the servers failed. This solution also included 256 GB of memory and 12 TB of storage. The installation was to be in a small data closet, and an air conditioning system would be required.
LiquidCool Solutions (LCS) proposed a more cost-effective solution, comprising three liquid-submerged servers with a total of 24 usable cores, 256 GB of memory and 12 TB of storage. Cooling was accomplished with a remote passive radiator.
The cooling power usage effectiveness (PUE) for the LCS installation is continuously monitored and typically reads 1.03. The PUE for the Dell solution would have been above 2.0.
An economic comparison of the LCS and Dell solutions is compelling. The client calculates total upfront capital cost saving for the LCS solution, including IT hardware and cooling equipment, to be $28,000. In addition, the LCS system does not need air conditioning, so there is no associated energy consumption and maintenance, resulting in an estimated operating expense savings of $4,800 per year.
