Topic: UPS for Server Room Devices

[bolang_bilog]

Mga ka-espiya, magandang hapon po... Magtatanong lang po sana kung saan pwedeng makabili ng UPS 200Vac na makakapag supply ng electricity during power outage sa at least 10 devices, kahit na at least 2-3 hours, may nakikita po kasi akong UPS sa hardware stores pero hindi ako sure kung ok ba ang mga iyon... yung UPS po kasi namin dito yung malaking parang CPU ang form factor, yung mga nasa hardware stores na nakikita ko naman po ay parang AVR lang ang laki, reliable po kaya yung mga iyon? Gusto ko po sana bumili ng reliable po talaga na UPS para sa server room namin, napag utusan lang po kasi ako...

Salamat po ng madami in advance.

for enterprise size UPS, you cant buy these from hardware stores or shopping malls.

keep in mind that the UPS is not meant to power up any IT environment for 2-3 hours. UPS are meant to power up IT equipments for long as a power generator can start. it is not a replacement for power generators.

1. if you say 10 devices, what are these 10 devices? are these all servers? network switches? do the servers have redundant power supplies?

2. UPS capacity is measured in KVAs. to correctly size up your required UPS, measure the total wattage of all the equipments and give this to your UPS supplier. for estimate, best practice usually starts at 5KVA UPS to power a rack cabinet containing 8 small to medium enterprise servers, each having a 400watts power supply, 1 storage area network switch, 1 storage and a rack mounted kvm switch.

depending on the number of batteries the UPS is using, it will state the number of minutes it will power up your equipments.

the measure 200Vac means, the power output is 200 Volts Alternating Current. it does not specify the amperage of your UPS requirement.

put it this way. yung mga nabibili na UPS sa mall na 600VA, it can only power up a desktop computer for less than 30 mins. yan yung mga parang AVR na sinasabi mo.

you want it to power up 10 equipments for 2-3 hours, thats gonna be about a size of a chest freezer. or kung naka-rack naman yung equipments niyo, better go for rack mounted UPS with separate battery enclosure. if you have redundant power supplies, connect only once power supply each to the UPS, the other on a surge protected power source.

Thank you Sir for the information. We are planning to purchase enterprise size UPS, where could I get one? By the way, our IT devices were mixes of Router, Switches, and Network Attached Storage devices.
