Troubleshoot a Fibre Channel SAN by proving the failed path first, then working from link state and optics through fabric login, zoning, LUN masking and host multipathing. Capture evidence before resetting anything; the failure pattern usually tells you where to look.
Choosing between VMware, Hyper-V, Proxmox, and HPE Morpheus in 2026 isn’t just a technical decision—it’s a question of long-term value versus cost, flexibility, and control. In this head-to-head comparison, we break down how each platform stacks up so you can decide which solution truly fits your infrastructure and budget.
A Proxmox VE 9 upgrade is an operating-system and platform migration, not a routine package update. Check restores, boot recovery, storage, networking, repositories, guests and cluster health before approving any node for the move.
LEGO’s 6,130-piece Executor Super Star Destroyer is a 136cm-long UCS display model that prioritises structural engineering and cinematic scale over play. At £649.99 and more than 5kg, it demands both collector commitment and serious furniture.
AWS AI can suit teams with sound AWS practices, usable data and a bounded problem. But Bedrock or SageMaker AI access alone does not establish readiness: costs, security, governance, skills, lock-in and measurable value all need testing.
The enterprise rush to deploy AI agents is running into a familiar problem in a new form: identity. If an agent can act, call tools, move data or trigger workflows, it needs a proper identity model, not a vague service account and a hope that logs will be enough. That shifts the discussion from ‘what can the model do?’ to ‘what can this agent prove it is allowed to do, and how is that enforced?’
US data centres consumed an estimated 17.4 billion gallons of water on site in 2023, but national totals obscure the decisive questions: local supply, seasonal demand, electricity-related water use and who funds new capacity.
Microsoft will make passkeys the default sign-in method in Entra ID from 1 September 2026 and retire Microsoft-provided SMS and voice delivery on 1 February 2027. The key risk is strand-through: recovery and helpdesk flows that still assume telecom MFA.

Critical unauthenticated code execution in specified Silicon One-based Cisco Nexus 9000 switches can give a reachable attacker root privileges and reload the device. Operators should urgently establish exposure, restrict access and upgrade using Cisco’s platform-specific guidance.

Broadcom’s VMSA-2026-0006.2 adds vSphere 7.0 guidance for two unauthenticated, network-reachable vCenter flaws rated 9.8. With no workaround available, restrict access and use the supported patch route as an emergency change.
A newer Microsoft Defender security intelligence update appears to restore failed scans on affected Windows PCs, highlighting why rapidly delivered endpoint-protection updates need monitoring, staged deployment and clear recovery procedures.
One useful technology briefing a week. New articles, practical fixes and the things worth paying attention to — no daily noise.
