Would you like to put a hard power capacity limit on a rack to ensure failover success or put a limit on a set of racks?
Load shedding can be the answer to preventing rack circuit-failover failure.
When dealing with PDUs there are already limits to the load capacity of a single device. It comes in the form of floor PDU circuit breakers. However, the capacity limit of a rack can exceed the limit of a single rack circuit. This is due to the fact that you typically load balance between two or more circuits. In other words, each circuit could be under capacity but when you add the loads together (loss of one circuit/failover) you exceed the capacity of one of those circuits. Under these circumstances, you could lose the whole rack because a failover would not succeed.
One way to make sure you don't exceed the capacity of a single rack or any set of racks is to utilize these key features of the Raritan PX line of PDUs:
1. Load Shedding — You pre-configure a group of outlets on a PDU that you want to be turned off when a particular event arises. The load shed outlet group may just be unused outlets and the load shed just keeps these outlets from being used.
2. LUA Scripting — Create a LUA script with JSON-RPC that can be run on one Raritan PX PDU that collects inlet current readings from other PDUs, adds that to its own inlet current reading. Then, based on a Boolean operation, executes that pre-configured load shedding on the local PDU as well as notifying the other PDUs to execute load shedding.
3. JSON-RPC API — Instead of a LUA script on a PDU, create a script (python/perl/java) that utilizes the PX API to perform the above (step 2) but run this on an element management system or CMDB or anything capable of running scripts. Just load our PX Software Developers Kit on the system where this will run.
If your racks are not configured so that a single circuit can handle a failover, it could be costly when you do have circuit failure. Because of these 3 exclusive features of Raritan's PX line of PDUs, you are able to keep loads under a set capacity. And not just report that something bad could happen, but do something about it, before catastrophe strikes. This is just one of many unique features of the PX series of intelligent rack PDU.

Top Four Concerns for Data Center Managers
Preparedness is often the first step for resolving potential challenges and devising solutions. As such, in order to properly prepare for the future of data centers, it is important to first understand the top concerns for data center managers.
1. Climate Change. -- In a recent 2018 study, more than 50 percent of participating organizations were concerned about the potential for climate change disruptions to existing data centers. Throughout the globe, organizations need to take into consideration the potentially negative impacts of rising temperatures, growing floodplains, and an increase in violent storms. All three types of climate change coincide with the increase in region-wide disasters. In order to prepare for this potential challenge, data centers need to include disaster and emergency planning efforts into the broader business continuity plans for the entire organization.
2. Data Center Infrastructure Security Threats. -- Due to the nature of the sensitive business and personal information that they hold, data centers need to remain vigilant for potential infrastructure security threats. Recent studies show that these attacks are more frequently being conducted on an IP-basis. As such, organizations need to effectively control how machines are connected to their data centers. Through private networks, a limited number of access points, and stringent monitoring systems, data centers can remain prepared to effectively combat infrastructure security threats.
3. Emerging Edge Computing Capacity. -- Edge computing is set to be one of the emerging technologies that disrupt the data center sector. This type of technology is a direct response for the need to process data closer to where it is generated, consumed, integrated, and computed. As with any emerging data center technology, the concern for many managers lies in security and data sovereignty. However, as organizations require access to data at the "edge," these solutions will continue to be implemented for a variety of purposes. From "store and forward," to data consolidation and backup, self-contained micro-modular data centers will play a key role in deploying a viable solution for edge computing.
4. DCIM Strategies. -- Data center complexity is on the rise. As a response to this increased complexity, the requirements for control, management, and visibility from DCIM software has also grown. Fortunately, DCIM products have recently matured to now offer rich, scalable, and stable management solutions to increase the forecasting, agility, and efficiencies of data centers. While it is still an under-deployed technology, it is expected that as it continues to mature, so too will it become a more widely adopted solution. The challenge for data center managers will be creating and implementing the operational changes needed to support DCIM software.
The Bottom Line: Be Prepared for Upcoming Challenges
Climate change, data center infrastructure security threats, edge computing, and DCIM strategies are all concerning areas for data center managers. As these emerging technologies continue to be adopted, data centers will need to take a proactive approach. Through a state of preparedness, data centers can more readily adopt the technologies needed to meet the growing needs of organizations. Finally, with the right knowledge and preparation, data centers can continue to grow and evolve as they adopt new technologies, address the concerns of data center managers, and meet the evolving needs of organizations.

With the rapid expansion of data centers creating highly complex IT infrastructures, it’s becoming more important than ever to find ways to increase the efficiency of day-to day operations. One of the most practical ways to achieve improved efficiency is through devices that are easy to use and easy to deploy.

Major changes in data centers operations have historically involved the location of data processing. At one time, this function was moved off-site to mainframes, but the advent of microcomputers, now known as desktops or PCs, brought data processing back to the customer’s own data center. Cloud servers and collocated data centers resulted in data processing being performed off-site once again.
Today, some organizations are using micro data centers to process data on their own premises. This solution can provide performance improvements that justify the initial expense of a data center and has the potential to gain wide acceptance in the near future.

If you’re an IT leader, you’ve probably made significant investments in data center management over the past few years. That’s because the success of the organization you serve depends heavily on the technical and economic performance of your data center. So the more digital your organization becomes, the smarter you have to be about how you manage your data center infrastructure.
Chances are, though, that you’ve focused on aggregate management of your data center as a whole. That’s good – but it will only get you so far. To fully optimize the value your business derives from its data center capex and opex, you must aggressively pursue operational excellence at the rack level.

An Intelligent Power Distribution Unit (iPDU) is a networked power distribution unit that increases the efficiencies of data centers with real-time remote power monitoring, environmental monitoring, and data center infrastructure integration. Intelligent rack PDUs deliver technologies which enables a smarter IT infrastructure so you can stay ahead of problems before they occur. They help achieve the ultimate goal of any data center manager, maintaining uptime while reducing cost.
