BEMS
hardware requirements for up to 150,000 devices

For up to 150,000 devices, install
BEMS
on its own server. This configuration requires multiple
BEMS
servers (not including high availablilty or disaster recovery scenarios). One dedicated instance of
BEMS
can support approximately 10,000 devices. To support more devices, add more instances of
BEMS
.
Use the BEMS Performance Calculator to determine the minimum number of
BEMS
instances for your device configuration and workload.
The servers that
BEMS
is installed on must be physically located near the server that hosts the
Microsoft SQL Server
database (less than 5 ms latency).
If you install both
BEMS
with
BlackBerry Push Notifications
and
BEMS
with
BlackBerry Connect
, install
BlackBerry Presence
on only one of those two servers.
