IS and IT managers demand more uptime for today's enterprise applications. Whether these be on-line transaction processing, supply chain management, or centralized file and print, Symmetra is the ideal power protection solution. The reason is that Symmetra's Power Array technology provides more uptime and higher availability than traditional, legacy UPS's. Legacy in this case refers to traditional, non fault tolerant, UPS systems.
How much does your old UPS sytem cost you each year?
The following chart can be used to estimate the cost of down PC's or other telecom equipment in your company. The costs can be huge! Because Symmetra is completely fault tolerant, uptime is virtually 100% vs. 95% for even the best legacy UPS systems. That extra 4 to 5% over a year is a lot of hours!

|Total cost per event ( 6 + 7 )||8||$4.71 mil||_______|
|Rsik cost of unprotected system ( 15 x 8 )||9||$70.1 mil||_______|
|Cost of protected system with legacy UPS( 95%x9)||10||$3.54 mil||_______|
|Cost with Symmetry System (9 x Symmetra Gap )||11||$7065||_______|
The factor of 15 in row nine, comes from LAN Times estimate of 15 power events per year that can take down a PC network.
The Symmetra Gap factor is defined as the equation ( 1.0 - % uptime ) for the unit. It is the time that the network is vulnerable because the UPS if off line. The MTBF numbers are so high for the Symmetra that uptime is at 99.99%!! The cost of downed networks in typical, large company is in the millions annually. Return time on investment can be a few days in this situation. If the company is larger, payback can be in the hours even for a dozens of Symmetra units. For a smaller firm of one million in annual sales, the annual cost of lost network perfomance is $8800 for a legacy UPS system. The SY8KEXPD Symmetra costs $9500, so the payback is about one year.
Remember that the numbers in the example are per year, each
and every year. A $400 million a year company is flushing $3.5 million every year that
they stay with conventional UPS hardware. As the company grows the risk and lost revenue
grows along with it.
Essentially, Symmetra is to power protection what RAID is to a normal disk drive. Symmetra is made up of modules that run in parallel. These modules back each other up and can be hot-swapped while the load is up, running, and fully protected.
In datacenters, clustering, mirroring, and RAID provide redundancy for processing and storage devices. Yet legacy UPS's are the weak link in enterprise reliability because they are not redundant. Symmetra provides redundant power paths that remove this weak link.
There are actually four advantages to Power Array technology over legacy UPS's: redundancy, scalability, serviceability, and manageability.
When your computing applications are vital to business operations, downtime is unacceptable. A Power Array's N+1 Redundancy ensures maximum uptime and high systems availability. The other components will automatically share the load without interupting the output voltage. This feature applies to all parts of the Symmetra including the power modules, batteries, and the controller modules. If a part does fail, the Symmetra can be programmed to email or page someone for assistance. Power modules and batteries are then easily replaceable while the unit is in service. The end users will never know any part failed.
Scalable kVA and runtime protect your investment. They
ensure that Symmetra will meet your power needs now and in the future. Add power capacity
in 4kVA blocks, and add Extended Battery Frames for long battery run times.
Symmetra gives IS Managers service flexibility. The reason is that the system is serviced by hot-swapping modules, which can be done by a non-technical person. Again, the power is on while the power modules or batteries are changed or added. No downtime occurs!
Legacy UPS manufacturers have a mainframe-type mentality of requiring a trained engineer to service their units. These companies rely on this service revenue stream and are hesitant to eliminate it.
With Symmetra, customers have three options for service, all of which make service more reliable and less expensive than the competition.
First, if customers wants to eliminate service costs entirely, they can service the unit themselves. A simple walk-through of how to service Symmetra is included in the owners manual.
Second, some companies have a single service provider for their datacenter already. That same service provider can service Symmetra as well. That means that data center managers don't have to add another service contact, another process to document, and another phone number to remember.
Third, customers may want APC on-site service for remote sites or for convenience. In this case they can choose an on-site service contract directly from APC. APC's new PowerPlan Service Suite meets this need.
Symmetra's combination of redundancy and modularity make maintenance flexible, inexpensive, and, most importantly, foolproof.
Want lager run times? Just add more batteries. The KEX large frame can hold four batteries. Addtional battery housings can be added as shown in the configuration guide above. The chart below gives run time as a function of the number of batteries. A maxium of four batteries can be used in a Symmetra without an external battery cabinet.
Four Smart Slots in Symmetra give network, SNMP, and out of band communications. And Symmetra's PowerView Display puts all that information right at your fingertips.
The Symmetra can be setup to email or page users for certain events if desired, via the included Powerchute software or an optional SNMP adapter. This is a smart unit that will warn the sysdamin of any hardware failures, weak battery conditons, long term power outages that required a controlled, server shutdown, etc. NT, Unix, and '95 software are all included with the Symmetra. Plus all of this can be remotely managed from offsite as well via the 10BT SNMP adapter and HP Openview software.
Total Enterprise Solution
Symmetra provides a complete enterprise power solution when used with APC's
accessories. Customers can gracefully shut down multiple file servers with Share-UPS,
reboot individual devices such as locked-up servers with MasterSwitch, and monitor
temperature and humidity with the Measure-UPS environmental device.
So whether you're protecting a computer room, server room or datacenter, Symmetra and APC's full line of products and services ensure that you have a total enterprise solution.
