Remote Power Management: Restart Frozen Servers Without On-Site Intervention
A hung server can be restarted remotely via the BMC, from a graceful shutdown to a switchable PDU. This article explains the five-step escalation chain and its limitations.
Virtual Media: Installing Operating Systems Remotely
Virtual Media allows you to install an operating system using a remote ISO file, without requiring any physical media on the server. This article explains the technology, supported hardware, and limitations when bandwidth is low.
Firmware Updates Across Hundreds of Servers: Centralized Management
Firmware updates on individual servers can be completed quickly, but when applied across hundreds of systems, it becomes a process in its own right. This article describes automation, RedFish standards, and a robust rollout process.
BMC Security: The Underestimated Point of Entry
BMCs operate independently of the operating system and are therefore often overlooked, while vulnerabilities such as CVE-2013-4786 or CVE-2021-39296 remain unpatched. This article assesses the current threat landscape.
IPMI Replacement: The Migration Path to Redfish
IPMI is no longer being developed; Redfish has been considered its official successor since 2020. This article describes a four-phase migration path and highlights the limitations of the transition.
KVM-over-IP at Fleet Scale: Architecture for Multiple Locations
Managing KVM-over-IP across multiple locations is a matter of balancing central control with local autonomy. This article compares common solutions and their limitations.
Out-of-Band Management: Accessing Servers When They Stop Responding
When SSH and Remote Desktop stop responding, out-of-band management via the BMC is often the only way to access the server. This article explains how it works, provides market statistics, and discusses the security risks associated with open controllers.
