SMBs: Get More with Less from Your Power Protection

Your critical power infrastructure consists of multiple rack-based UPS units rather than a centralized UPS system You are adding server or network equipment in spaces not designed with proper power conditioning and backup power You have dual corded equipment but aren’t able to take advantage of the benefits of dual bus power You are using UPS technology that has failed and dropped power to your equipment You have less backup time than you need for saving data and planning an orderly shutdown You are virtualizing servers, but haven’t calculated the power demands of the consolidated environment You have no structured plan for maintaining and replacing UPS systems Warning signs there may be vulnerabilities in your power infrastructure

Availability: Tier levels of protection

“ Existing data network protection may not work for IP telephony systems. It is important to provide adequate power and cooling for all IPT components, especially in network closets and remote sites.” - Rich Costello, Gartner “ With virtualization, since each server runs multiple virtual server workloads, the server becomes a single point of failure. This escalates the issue of availability for that physical server. If you put all your virtual eggs in one basket, then you need to take very good care of that basket.” - Barb Goldworm, B lade Servers and Virtualization Virtualization and IP telephony initiatives increase criticality

How a UPS does its job

Sags Surges Spikes Outages Frequency Variations Waveform Distortions Noise Affecting equipment daily The reasons why you need a UPS

Off-line UPS: Load is powered directly by the input power and the backup power circuitry is only invoked when power is lost Not recommended for business-critical applications or technologies Line-interactive UPS: Maintains the inverter in line, redirects the battery's DC current path from the normal charging mode to supplying current Provides adequate protection for some applications Not recommended for truly business-critical equipment Not recommended for areas where utility power is inconsistent On-line UPS: The UPS accepts AC input power, the rectifier converts AC power to DC for charging the battery, the inverter converts DC power back to AC for powering IT equipment Recommended for applications where tolerance to downtime is low Different types of UPS

Off-line UPS: Load is powered directly by the input power and the backup power circuitry is only invoked when power is lost

Not recommended for business-critical applications or technologies

Line-interactive UPS: Maintains the inverter in line, redirects the battery's DC current path from the normal charging mode to supplying current

Provides adequate protection for some applications

Not recommended for truly business-critical equipment

Not recommended for areas where utility power is inconsistent

On-line UPS: The UPS accepts AC input power, the rectifier converts AC power to DC for charging the battery, the inverter converts DC power back to AC for powering IT equipment

Recommended for applications where tolerance to downtime is low

Different types of UPS performance Risk Line-Interactive UPS On-line UPS Battery Failure 2-3 year life 5-year life Power Conditioning Provides protection against most power problems Provides protection against ALL power problems Reliability MTBF of > 125,000 hours MTBF of > 278,000 hours Overloading Handles up to 110% of capacity Able to handle any overload via internal bypass

Different types of UPS results

On-Line Double-Conversion UPS The UPS accepts AC input power, the rectifier converts AC power to DC for charging the battery, the inverter converts DC power back to AC for powering IT equipment OUTPUT POWER INPUT POWER Batteries or Flywheels AC DC DC AC RECTIFIER INVERTER STATIC SWITCH Power Storage

The backup storage systems powers the inverter when the rectifier does not have power. The bigger the storage system the longer it can power the inverter. OUTPUT POWER INPUT POWER Batteries or Flywheels Using stored energy AC DC DC AC RECTIFIER INVERTER STATIC SWITCH Power Storage

The static switch serves as a bypass for the converters allowing the UPS to be maintained OUTPUT POWER INPUT POWER Batteries or Flywheels UPS on bypass AC DC DC AC RECTIFIER INVERTER STATIC SWITCH Power Storage
