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.

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.
