Advances in enterprise computing and storage tech-

nologies are demanding a change in enterprise power pro-

tection technology. Today's computer room houses mis-

sion critical applications and databases running on Wintel

and Unix-based machines, web servers, and dozens to

hundreds of consolidated file and print servers. The relia-

bility and availability of these machines depends on tech-

nological advances such as

RAID storage, server mirror-

ing, server clustering, and

fail-over recovery.

Despite these advances in

storage and processing avail-

ability, the mid-sized power

protection industry has been

populated with only legacy

UPSs - centralized box-type

UPSs that create multiple

single points of failure. These

UPSs offer little in the way

of redundancy and scalabili-

ty. According to one frus-

trated director of the

Uninterruptible Uptime Users

Group (UUUG), “a single

legacy UPS failure can wipe

out three years worth of

carefully planned and con-

trolled systems uptime.”

But that all changes, with

an exciting new power protection technology from APC:

Introducing the world’s first Power Array, a completely

new category of power protection system designed by APC

to meet today's customer demand for scalable and highly

available power solutions.

A Power Array is a single unit composed of

modular components. This modular architecture

provides the foundation for building and scal-

ing near-continuous availability power systems

with a flexible range of power capacity.

Figure 1 (right) shows a diagram of a typi-

cal datacenter with a legacy UPS protecting

processing and storage devices. Servers use

clustering and mirroring technologies, and stor-

age devices use RAID technology to create

redundant paths so that no CPU or drive is a

single point of failure. Since the power path

from a legacy UPS is not redundant, the overall

system availability is constrained by the UPS.

Figure 2 (right) shows how Power Array technology

matches the modularity, redundancy and scalability of

RAID and server clustering and mirroring to increase

overall systems availability. In fact, Power Array technol-

ogy, combined with it’s manageability and serviceability,

represents a fourfold advantage over a traditional UPS.

Power Array redundancy reduces the risk of systems

downtime. By using an N+1

redundant Power Array,

customers ensure maximum

uptime and near-continuous

systems availability.

Power Array scalability pro-

tects your investment in power

protection by enabling expan-

sion or reconfiguration simply

by adding or removing modules.

Scalable runtime allows extend-

ed back-up time with the addi-

tion of Battery Modules.

Scalable power capacity enables

you to pay as you grow by

adding Power Modules in incre-

ments of 4kVA.

Power Array serviceability

decreases the cost of systems

ownership. Modular and hot-

swappable components make

maintenance simple.

Power Array manageability

means you can use APCs existing software and acces-

sories to monitor and control your power and environ-

ment, as well as to shut down multiple servers and reboot

individual locked up machines.

Power Array

™

The Symmetra

™

Power Array

™

does for power

protection what RAID did for data storage.

Total Solution

The Symmetra Power Array combines with the complete

line of APC datacenter protection software and acces-

sories to provide the four most critical elements of total

datacenter protection: redundancy, scalability, manage-

ability and serviceability.

This total solution promises to change the way you look

at computer room power protection.
