Understanding a power distribution unit
Datacenter and its power distribution units have gained prominence due to the increasing dependence of the IT industry on data generation and its management. The entire operation of the IT infrastructure is dependent upon power distribution units (PDU) to disseminate power to the servers and business-critical equipment within the IT infrastructure facility. It has multiple outlets that connect with the networking equipment as well as storage devices within the rack. So, PDUs play an important role in distributing the power through multiple outlets to ensure consistent, reliable, and adequate power supply throughout the servers and networking equipment to ensure business continuity.
Choose your PDU wisely!
Now that the importance and reliability of PDUs are understood within the IT ecosystem, it is relevant to analyze the difference between a basic and intelligent PDU. This will help one to choose the PDU appropriate for the business to gain long-term value.
Basic vs. Intelligent PDU
A basic PDU is a standard and dependable power supplying unit. It distributes power from the UPS system, generator, or utility wall outlet to equipment racks within the Cabinets. It is a convenient and cost-efficient solution that complements the benefits and features of a UPS system by converting a single high-amperage UPS outlet to multiple low-amperage outlets. Hence PDU can be considered as the easiest and most efficient way of distributing power to multiple rack loads when the requirement is basic and clearly demarcated. However, perfect a basic PDU may appear it cannot handle the challenges a data center faces such as:
Now, compared to the basic PDUs, the smart or intelligent PDUs cater to specific IT infrastructure with complex requirements. It meets the need of modern data centers to make optimal use of power, space, and cooling. It can monitor circuit breakers that enable users to locate where the trip occurred to reset it. It is an advanced version of the standard PDU that hosts a wide range of features and has the capability to address all the challenges that a data center faces in a cost-efficient manner. Hence it is more operationally efficient, reliable, and environmentally sound for data centers with critical operational workflow.
Intelligent PDUs can be categorized into the following types.
Why does Netrack trust intelligent PDU?
Netrack offers intelligent power distribution units solutions to IT enterprises to improve utilization of power resources along with equipment uptime and capacity planning decision. The focus here is to save power, ensure business continuity, save money, and becoming a green data center. The SNMP alerts and user authentication through LDAP, MSAD, CCSG play a crucial role in it. Let us now consider the advantages of intelligent PDUs that gained trust.
Make a difference with intelligent PDU!
Ensure your business continuity with optimized power and cooling management through iPDUs while reducing both energy consumption and cost. Hence, boost your data center performance, capacity planning, and increase the uptime of business-critical equipment.
A PDU (Protocol Data Unit) is defined by which layer it is in. In the physical layer and network layer, it is synonymous with the packet, in the data link layer, it is the frame. In the transport layer, it is a datagram for UDP. A datagram holds one or more PDU's, as it is the basic unit of transferring information via packet switching.
The PDU at the Network layer is referred to as a packet. A PDU at the Data Link Layer is referred to as a frame.

The PDU (protocol data unit) @ transport layer (e.g. TCP or UDP) is called as 'segment' .

What is a PDU? corruption of a frame during transmission data reassembled at the destination retransmitted packets due to lost communication a layer specific encapsulation
yes but not the other way around
In networking, PDU means "protocol data unit", and it is the generic name of the "packets" of data used at different levels of the network. Using the numbering of the OSI layers: At layer 2, the PDUs are called "frame". Example: An Ethernet frame, a frame-relay frame. At layer 3, the PDUs are called "packets". Example: An IP packet. At layer 4, the PDUs are called "segments". Example: A TCP segment, a UDP segment.
