ServerLSL™ (Server Level Sealed Loop) replaces less efficient air coolers and enables data centers to utilize the highest performing CPUs/GPUs. In cases where budget limitations are paramount or in a transitional data center (a mix of low density air cooled & high wattage liquid cooled racks), Asetek ServerLSL is ideal. ServerLSL replaces less efficient air coolers with liquid coolers and exhausts 100% of this hot air into the data center with the overall data center heat being handled by existing CRACs and chillers. In addition, ServerLSL requires no changes to the data center infrastructure.
Asetek ServerLSL is “Liquid Enhanced Air” cooling for server nodes. Because the low pressure pumps are contained within each ServerLSL node, individual liquid cooled servers can be installed in the same racks with air cooled servers. The is a key advantage over centralized pumping systems that require high pressures and whole racks (or multiple racks) of liquid cooled servers to be installed. ServerLSL provides significant power savings on the internal server fans, allowing the use of higher wattage processors in any given server design while reducing fan noise in the data center.
ServerLSL can serve as a transitional technology from air cooling to Asetek’s “free cooling” solution RackCDU D2C. Unlike Asetek RackCDU D2C, ServerLSL still exhausts 100% of its hot air into the data center with the overall data center heat being handled by existing CRACs and chillers. In this way, ServerLSL can serve as a proof point for IT and Facilities management who understand the benefits of liquid cooling but must deal with management fears of liquid cooling in the data center.
Calculating the Benefits
Data Center Power Savings Example:
With Asetek ServerLSL:
Total Savings: 2.2kW per rack or $1,927 in net power savings per rack per year.
