Rittal presents the completely redesigned, third-generation monitoring solution: CMC III. The CMC III's most important innovation is the use of a series-connected CAN-bus, which significantly reduces the cost of installation and wiring. Besides this, sensors that monitor the cold air intake and the server rack door are now standard features.
The CMC III housing has also been completely redesigned: it now takes up far less expensive space in the server rack.
Rittal presents CMC III, the third and completely redesigned generation of the Computer Multi Control (CMC) monitoring systems. Its most striking new feature is the change to CAN (Controller Area Network) buses:
These standardised and very robust field buses are integrated in the central processing unit and in Rittal's intelligent sensors. Thus, unlike traditional I/O units, the CAN-bus sensors are not individually connected to the central processing unit, but rather to each other in series:
A CAN bus, linked to the buses in the neighbouring enclosures, is found in each server enclosure. Data is simply "fed through" until the data arrives in the central unit. The reduced complexity means there is much less unwanted cable clutter when installing, maintaining and modifying the system.
Since far fewer modules are needed, the cost of the system is also slashed. Rittal has also taken a new direction with sensors: Thus the two most important functions - the temperature sensor for the cold air intake at the front of the server, and an infrared sensor, which determines whether the enclosure door is open or closed - are already integrated in the central processing unit as defaults.
Space-saving, comfortable, automated
The CMC III enclosure has also been completely revised - it now requires far less expensive space in the server rack. Just one-third of a height unit is enough space for the third generation CMC's processing unit. In addition, the new power pack is housed in an identical enclosure, which is easily installed in the same height unit and connected via cable. Power supply via Power over Ethernet (PoE) is also possible.
With the CMC III, network integration, as well as configuration and commissioning are performed comfortably with a laptop and a USB port. The user can choose between TCP/IPv4 and TCP/IPv6 as network protocols. Working with RiZone IT infrastructure management software and the Microsoft System Center Operations Manager, CMC III is capable of initiating automated counter-measures. Emergency situations can thus be defused immediately without human intervention, while the responsible members of staff are alerted by text message or e-mail.
