Opengear Application Note: SDTConnector + Dell Page 14 of 14
7. The Dell + Opengear solution
So Opengear IM4200 gateways and SDTConnector client ship preconfigured with support for Dell's BMCs and DRAC cards and
associated OpenManage tools – and they provide the ideal solution for securely accessing and controlling these service
processors and Dell servers and storage devices.
For enterprises with distributed branch offices the IM4200 family provides a powerful integrated solution. In the smaller branches
with only a few racks of servers and network devices to administer, the IM4200 offers a single point of local and remote access
to all the serial consoles, network consoles, service processors and power units at the site. In larger branches with racks of
servers to administer, the IM4200 can serve as the management LAN gateway that securely isolates the service processors.
For the SMB customer the IM4216-25 + SDTConnector offers integrated out-of-band management fabric for DRACs/BMCs and
remote access to Dell tools as well as management of non-Dell serial console equipment. It also delivers alternate connectivity
for the out of band access with broadband and dial-up support. And for data center customers with racks of serial console
devices to administer, the IM4248-2 (with its redundant power supplies, Ethernet failover, authentication and logs of all
accesses) provides a most reliable solution, while the CM4148 provides a most affordable solution.
When locally administering a Dell server the OpenManage and IT Assistant applications address the server at one TCP/IP
address on the LAN, the RAC Services tools address the DRAC at another IP address and the BMC is access for SOL and for
IPMI connection using yet other UDP and TCP IP address. A selection of authentication and encryption options will then have
been configured for each of these accesses. Administering this server remotely requires all the firewalls and routers in the
enterprise network to be configured to allow communications through all these ports. Administering a distributed network of such
servers remotely adds another layer of complexity.
The SDTConnector client that is supplied with each IM/CM4000 provides a simple centralized solution for administration of such
distributed networks. With an IM4200 solution all the OpenManage, IPMI and SOL access to each remote Dell server is securely
tunneled thru SSH over the one selectable port. SDTConnector then gives the sys admin secure access to all these local and
remote servers and sites from the one screen on his/her desktop, and appropriate tool for accessing a particular server can then
be opened with a simple point-n-click
