Data centers supplied to Banca Popolare di Sondrio began to manifest obsolescence problems from a structural standpoint, since the air-conditioning systems that were to be no longer adequate. “Our server farm had grown rapidly since the deployment of Web services and the use of dedicated devices”, explains Piergiorgio Spagnolatti, Contact Server Farm and Distributed Systems. “At this rapid development and the consequent concentration of devices it had not followed proper sizing infrastructure. The old environments had remained linked to a system of distribution of the current and the cooling enough dated “. We are talking about 90 physical servers and over 600 virtual, to which are added the various storage systems. “We considered this critical, equipping our data center, system power and cooling up to fulfill a function crucial to the Bank’s Business Continuity”. By optimizing the spaces dedicated, one would have to proceed with the consolidation of all venues on one island and the use of an air conditioning system lnRow in high density.
On this basis it was the decisive contribution of Lan & Wan Solutions, which closely with the IT team of Banca Popolare di Sondrio has developed a solution in line with the objectives to be achieved. “We evaluated several alternatives for containment components and plant engineering, especially in cooling and power distribution,” says Spagnolatti. “Only IT technology of Schneider Electric was the closest to the prerequisites and logistical constraints which were subject, providing some of the features to monitor the consumption and availability of systems not found in other solutions considered.” Lan & Wan Solutions has fielded a project-based solutions ISX Schneider Electric, with two rows of cabinets containing nine rack set up with both the hot aisle, where are concentrated the components whose overheating should not be at the expense of ‘system integrity; it comes to data center architecture that optimizes the air conditioning system. In each of the racks have been installed units power distribution (Rack Mount PDU) for feeding the server, allowing the switch on, off and auto reset of each outlet also remotely via a web browser, as well as ISX console.
Also the unit for cooling the air are part of the ISX Schneider Electric solution and have been installed in line with the racks. The proximity of air conditioning carriers to the heat source enables more effective, avoiding the waste of energy. “For each corridor are used one or more lnRow systems to dissipate heat,” adds Angelo Panizza, Telecommunications Manager, Server farm and distributed systems. “The air is sucked through the rear of the system, cooled and fed back into the cold aisle, neutralizing the effects of excessive heating of the devices for data processing. The lnRow RC System provides a high volume of air flow, up to 11,725 cubic meters per hour with a maximum cooling capacity of 29KW, to eliminate overheating of high-density systems “.
The configuration of the cooling systems to which the solutions are equipped ISX, involves a higher energy efficiency level, as it enables higher temperature thresholds, provided that both air return. All this is part of a modular system which enables the addition of further conditioning devices in case of increase of the content apparatuses.
