KVM Switches vs. Software-Based Remote Access Tools

Michael Bord

Many organizations rely on either enterprise KVM switches or software-based remote access tools to control multiple computer systems, often over geographically dispersed areas. While there may be some overlapping capabilities when it comes to mundane everyday activities such as server routine maintenance, both systems have inherent strengths and weaknesses that are important to assess before committing to one over the other. 

Metered PDU vs. Basic PDUs, and Advice on Power Load Balancing

Basic rack PDUs are little more than outlet strips. They deliver electrical power to IT devices and that is about all they do.

In addition to delivering electrical power, metered rack PDUs provide information about the power that is being consumed. It may be as simple as the voltage and the power being consumed by the PDU in total or it may provide much more power information and breakdown that information by each individual outlet. There is a wide range of PDUs that could fall under the description of a metered PDU.

Four of the Most Innovative Features of Rack PDUs

Rack power distribution units or PDUs have come a long way from where they started. Where once they were limited to supplying electricity to devices, they’ve now evolved to have sophisticated capabilities that help data centers manage their power chain more effectively. These are some of the most innovative features of rack PDUs today.

Why Choose a KVM with BIOS-Level Access

There are multiple remote access tools to make an IT administrator, Lab or Network Manager’s jobs easier.  Options include Remote Desktop Protocol (RDP), Virtual Network Computing (VNC), and KVM-over-IP, as well as many others. But only KVM switches provide the reliability you can depend on in the event of an emergency. 

Why the Hybrid Rack Transfer System is Superior to Both ATS and STS Systems

Lots of data center vendors offer transfer switches, but they normally fall into one of only two categories: relay-based Automatic Transfer Switches (ATS) or Static Transfer Switches (STS) that rely on silicon-controlled rectifiers.  Although effective in switching between power feeds, they both have inherent design flaws that hinder both performance and reliability – two areas where a hybrid rack transfer switch really excels.  But, to understand why the hybrid transfer switch is superior, you first need to understand the limitations of ATS and STS devices.
