Dominion KX II Release 2.3 is now available on raritan.com for customer download. With this new firmware, the KX II will support “tiering,” two levels of connection supporting the access of up to 1024 servers. In addition, the the Dominion KX II becomes the first digital KVM switch to support remote HD video resolution of 1920x1080. Other advancements include:
In addition, there are new security features and support for the Paragon Dual CIMs, which can connect one server to two KX II switches for increased reliability and access.
With this release we are reaffirming our leadership in the digital KVM market with support for HD video resolutions, supporting new customer configurations (tiering and the Paragon Dual CIMs), providing new levels of IT productivity, and remaining the most secure digital switch in the industry.

One would assume that data centers are a place where high tech gets introduced and the mass PC market is a followers market. However there are plenty of examples where it is just the other way around. For years the processor market was driven by the battle between Intel and AMD this battle was fought where the volume was and is consumer PCs. Another good example is the keyboard interface. Servers still used PS/2 when it was already hard to get a non-USB keyboard for consumer PCs. Also the good old VGA interface has only survived in the metal rack cabinets of data centers and data rooms.
Two more innovations from the main stream consumer PC market are about to enter the DC world and worth to be mentioned:

Data Center automation is a worthy and important goal for most organizations. This may be true whether you are running lights out, collocated or just with a lean staff. The more routine operations and processes that can be removed from required human intervention the better. Potential benefits range from improved delivery on SLAs, extended equipment life, reduced labor costs and even enhanced job satisfaction.
Automation systems are simply feedback loops. The components may already exist in your datacenter including sensors, polling and trap management and rule driven software to effect change. Unfortunately the right sensors in the right places in the right quantities are often lacking to complete the loop.
This is part one of a multipart series on automation techniques beginning with heat load management and related sensors.
CRAC / AHU Feedback Control
Below are just a few scenarios that can be a high value target for temperature sensor based automation:
Temperature sensors can provide the input necessary to proactively alert and remedy these situations.
With temperature sensors in the rack and an application that can perform power control we can automatically shed the heat load where temperatures have passed a critical threshold in a zone.
Raritan PX PDUs have this capability when temperature sensors are attached. No additional software or hardware needed. Furthermore we can turn the same systems back up automatically when the temperature is sensed to have lowered to an acceptable level.
Additionally a Raritan PDU can send an SNMP trap alert based on temperature sensor readings to any SNMP trap manager and any SNMP enabled application may perform the same outlet control on the Raritan PDU.
Without automation if your heat load varies by utilization you have two choices. Run cooler than needed for much of the processing day wasting energy or run hot and impact the reliability of your equipment. When we introduce automation we can change our cooling output to match the heat load and eliminate the undesirable outcomes above.
Temperature sensors in the rack can provide trigger data to an application capable of altering the CRAC unit output to match the current heat load. A poll of all sensors could be implemented or SNMP alerts could be sent to this controller application based on thresholds such as with the Raritan PDU attached sensors.
Increasing compute densities require increasing levels of precision when managing environmentals. Ashrae recommendations are for high, mid and low sensor placement that can facilitate temperature gradient mapping. With a single sensor in a rack an open KVM drawer could go undetected while obstructing airflow to equipment behind it. Similarly missing floor tiles can alter air pressure needed for the cool air delivery. Both air flow and temperature sensors are useful in this scenario.
Raritan PDU connected sensors have associated X, Y & Z coordinates to facilitate a proactive approach for immediate identification and location of these types of situations.
The next feedback loop automation we will look at next will focus on applications.

Green IT is the focus of attention these days all around the globe. Managers of big Data centers play a leading role in the adaption and implementation of processes, tools and devices that support the objective of becoming “green”. They start changing their power infrastructure in order to show the energy consumption in the Data center and generate power usage charts on rack level or even server level by measuring and logging data over a long time. Reasons for this new behavior are very complex. On the one hand there are new rules or laws forcing Data center Managers to save energy and reduce the Carbon footprint. Others simply want to save money by saving energy. A third group of Data centers are looking for a solution to exactly measure the power consumption so that these costs can be billed to their customers. Last but not least there are efforts to fully use the capacity of a Data center and thus postpone expansions or moves and, again, save money – all not possible without an active and intelligent energy management system.
Raritan is extremely focused on these efforts. With our intelligent power products we provide solutions for our customers which help them to comply with the above described requirements. However, this confronts our customers with the problem of transmitting and finally storing data generated by intelligent energy management solutions. For our customers this means they have to provide IT communication and storage infrastructure and embed it in existing infrastructure. We have learned that this task is a quite challenging logistical issue for many customers since it requires a smooth cooperation between IT Managers and persons in charge for Facility.
