Stratus ftServer 2600, 4500, and 6300 Systems: Site Planning Guide (R638)
Selecting a UPS Unit for ftServer Systems
Stratus does not sell or service UPS units. However, Stratus has qualified UPS models
for use with ftServer 2600, 4500, and 6300 systems.
Use Table 2-1 to determine the number of watts the A-side of your system requires and
use Table 2-9 and 2-10 to select a UPS model.
N O T E
Generally, system fault tolerance could be at risk if you
use a UPS with systems that run ftSSS for VMware
vSphere or ftSSS for the Linux operating system. These
versions of ftSSS do not include the logic to decide
whether the operating system should shut down in
response to certain signals from the UPS, and the UPS
may unnecessarily shut down the system.
If you have a situation that requires the use of a UPS (for
example, if you do not have two separate power sources
at the installation site), use the tables in this section to
select an appropriate UPS, do
not
use UPS signaling,
and contact the CAC or your authorized Stratus service
representative for additional assistance.
