I have a B.S. in Computer Science and will soon complete my Master\u2019s of Information and Data Science.<\/p>\n<p>In the early days of my IT career, I learned how to build systems from scratch, configure networks, and apply patches.<\/p>\n<p><strong>Like many, I was trained to focus on the obvious goals:<\/strong> keep things running, keep everything secure, and automate what I can.<\/p>\n<p><strong>But what no one taught me? <\/strong>What to do when everything goes dark \u2013 <em>literally.<\/em><\/p>\n<h3><strong>That\u2019s exactly what happened recently.<\/strong><\/h3>\n<p>ZPE\u2019s Fremont branch lost power unexpectedly and without notice from our provider.<\/p>\n<p><strong>One by one, our services went down<\/strong><\/p>\n<ul>\n<li>ESXi Hosts<\/li>\n<li>Backup Servers<\/li>\n<li>VPN Tunnels<\/li>\n<li>Core Routers and Switches<\/li>\n<\/ul>\n<p>[\/et_pb_text][et_pb_text _builder_version=&#8221;4.27.4&#8243; _module_preset=&#8221;default&#8221; header_font=&#8221;|700|||||||&#8221; header_text_color=&#8221;#358AAF&#8221; custom_padding=&#8221;||30px||false|false&#8221; global_colors_info=&#8221;{}&#8221;]<\/p>\n<h1>Here is the part that I wish I knew 20 years ago\u2026<\/h1>\n<p>You won\u2019t be rescued by dashboards, spreadsheets, or documentation when IT goes dark. <strong>What WILL save you is system design, <em>specifically out-of-band management.<\/em><\/strong><\/p>\n<p>And for which I am lucky that design did save us.<\/p>\n<p>Without Out-of-band (OOB), I would have had to spend the whole night at the office manually rebooting, configuring, and troubleshooting everything.

IT emergencies can really intrude on your life outside of work. It&#8217;s just part of the job.<\/p>\n<p>But I was so grateful to have OOB because it gave me a separate path dedicated to recovery, which was just what I needed.
