Virtualization Platform
Create your own virtualization appliance by leveraging
Intel Virtualization Technology (VT-x) to allow one
hardware platform to function as multiple “virtual” plat-
forms. Isolate your computing activity onto separate vir-
tual machines to maintain productivity and realize
improved manageability and reduced downtime. For
example, run a virtualized OS specifically for your HMI
or other essential but noncritical applications. Should
your HMI require that the system be restarted, simply
restart the virtual machine and avoid an outage for your
other critical processes. Similarly, multiple SEL-3355-2
automation controller platforms may be virtualized and
entire operating systems transparently migrated from one
physical SEL-3355-2 to another for hardware upgrades,
security or software updates, or testing purposes.
Control System Applications
Use the SEL-3355-2 for process control applications,
including as an HMI or for protocol conversion and high-
speed control when working with other SEL products
and solutions.

Security Applications
Improve security with a single sign on (SSO), enabled
through using the SEL-3355-2 as a local Lightweight Direc-
tory Access Protocol (LDAP) server. Centrally manage user
accounts and group memberships with Microsoft Active
Directory or with your choice of back-end database support.
