Flexible 400V Power Distribution

Posted on August 30, 2010 by Greg More  |  Comment (0)

Today’s high power demands, increasing power costs and constantly changing equipment require data center and facilities managers to look for power solutions that can deliver a lot of power but are flexible. A typical data center has both medium density (5-10 kW/rack) and high density (15-30 kW/rack) equipment racks. For example, some racks may have 2U/4U application and database servers, others may have 1U Web servers, still others may support blade servers, storage networks, or high density networking fabric.

The power requirements for this variety of equipment can range from single phase to three phase, rack power (kW) may be anywhere from 5 kW to 30 kW per rack, and there could be dozens of different physical receptacles. The key is to efficiently utilize the available power capacity and to maintain uptime to the greatest extent possible while changes are made.The traditional approach uses pedestals at several locations in the data center with under-floor conduit or whips from the pedestal to racks. All the cable under that raised floor can impede air flow and cooling. The fixed feeds lead to decreased flexibility and challenging serviceability. In fact, it is not uncommon for some cables to be abandoned in place.


Why Raritan IT is adopting a new naming scheme in Power IQ

Raritan IT team recently decided to change our naming and association schemes in Power IQ.   This change reflects the new level of power usage details IT wants to track, and how we plan to utilize such information to measure energy savings from the investment in replacing old servers with new, more energy efficient IT equipments.

In prior Power IQ naming scheme, we name the PX outlets by “phase-circuit-rack-L/R”.  From this naming scheme, one can easily tell that it was a PX-centric thinking.   Using Power IQ, IT was able to easily know the total data center power consumption, as well as power usage by circuit and by rack.  The power consumption by individual IT devices was interesting but not as important for power capacity planning, especially when the servers were largely 1U/3U rack-mount servers.


Government Security, Compliance and Remote Access

Posted on August 23, 2010 by Anthony Bonaventura  |  Comment (0)

IT administrators in the government space are concerned about three things when they arrive at their place of work: security, security and security.

With the recent, and not so recent, cyber attacks on military and civilian agency networks, the government is constantly looking to the OEM and system integrator communities for new solutions to insure the lock-down of federal information system networks and servers that carry and hold information critical to the security of our nation.

Couple this daily challenge with compliance directives issued in large part by executive orders and shrinking budgets, data center managers hands are full. Not to mention that these folks have some of the busiest days out of anyone in the federal IT space.
